the HUD display state is now persistent between app restarts
updated the Distance Tool such that the right click of the mouse will cancel the tool unless it was a panning move
modified the PlotCanvasLegacy to decide if there is a mouse drag based on the distance between the press event position and the release event position. If the distance is smaller than a delta distance then it is not a drag move.

6.05.2020

wip in adding Exclusion areas in Geometry object; each Geometry object has now a storage for shapes (exclusion shapes, should I make them more general?)
changed the above: too many shapes collections and the performance will go down. Created a class ExclusionAreas that holds all the require properties and the Object UI elements will connect to it's methods. This way I can apply this feature to Excellon object too (who is a special type of Geometry Object)
handled the New project event and the object deletion (when all objects are deleted then the exclusion areas will be deleted too)

final fix for app not quiting when running a script as argument, script that has the quit_flatcam Tcl command; fixed issue #360
fixed issue #363. The Tcl command drillcncjob does not create tool cut, does not allow creation of gcode, it forces the usage of dwell and dwelltime parameters
in NCC Tool I've added a warning so the user is warned that the NCC margin has to have a value of at least the tool diameter that is doing an iso_op job in the Tool Table
modified the Drillcncjob and Cncjob Tcl commands to be allowed to work without the 'dwell' and 'toolchange' arguments. If 'dwelltime' argument is present it will be assumed that the 'dwell' is True and the same for 'toolchangez' parameter, if present then 'toolchange' will be assumed to be True, else False
modified the extracut and multidepth parameters in Cncjob Tcl command like for dwell and toolchange
added ability for Tcl commands to have optional arguments with None value (meaning missing value). This case should be treated for each Tcl command in execute() method
fixed the Drillcncjob Tcl command by adding an custom self.options key "Tools_in_use" and build it's value, in case it does not exist, to make the toolchange command work
middle mouse click on closable tabs will close them

in Excellon Editor fixed the display of the number of slots in the Tool Table after the resize done with the Resize tool
in Excellon Editor -> Resize tool, made sure that when the slot is resized, it's length remain the same, because the tool should influence only the 'thickness' of the slot. Since I don't know anything but the geometry and tool diameters (old and new), this is only an approximation and computationally intensive
in Excellon Editor -> remade the Tool edit made by editing the diameter values in the Tools Table to work for slots too
In Excellon Editor -> fixed bug that caused incorrect display of the relative coordinates in the status bar

15.08.2019

fixed bug Excellon Editor: Measurement Tool was not acting correctly in Exc Editor regarding connect/disconnect of events
in Excellon Editor every time a tool is clicked (except Select which is the default) the focus will return to Selected tab
added protection in Excellon Editor: if there is no tool/drill selected no operation over drills can be performed and a status bar message will be displayed
Excellon Editor: added relevant messages for all actions
fixed bug Excellon Editor: multiple selection with key modifier pressed (CTRL/SHIFT) either by simple click or through selection box is now working

added a verification on project saving to make sure that the project was saved successfully. If not, a message will be displayed in the status bar saying so.

20.10.2018

fixed the SVG import as Gerber. But unfortunately, when there is a ground pour in a imported PCB SVG, the ground pour will be isolated inside instead to be isolated outside like every other feature. That's no way around this. The end result will be thinner features for the ground pour and if one is relying on those thin connections as GND links then it will not work as intended ,they may be broken. Of course one can edit the isolation geometry and delete the isolation for the ground pour.
delete selection shapes on double clicking on object as we may not want to have selection shape while Selected tab is active

29.09.2018

optimized the combobox item population in Panelization Tool and in Film Tool
FlatCAM now remember the last path for saving files not only for opening

made all the transforms threaded and make them show progress in the progress bar
made FlatCAM project saving, threaded.

23.09.2018

added support for "header-less" Excellon files. It seems that Mentor PADS does generate such non-standard Excellon files. The user will have to guess: units (IN/MM), type of zero suppression LZ/TZ (leading zeros or trailing zeros are kept) and Excellon number format(digits and decimals). All of those can be adjusted in Menu -> Edit -> Preferences -> Excellon Object -> Excellon format
fixed svgparse for Path. Now PCB rasted images can traced in Inkscape or PDF's can be converted and then saved as SVG files which can be imported into FlatCAM. This is a convolute way to convert a PDF to Gerber file.

22.09.2018

added Drag & Drop capability. Now the user can drag and drop to FlatCAM GUI interface a file (with the right extension) that can be a FlatCAM project file (.FlatPrj) a Gerber file, an Excellon file, a G-Code file or a SVG file.
made the Move Tool command threaded
added Image import into FlatCAM

21.09.2018

added new information's in the object properties: all used Tool-Table items are included in a new entry in self.options dictionary

fixed the utility geometry for Font geometry in Geometry Editor
work on selection in Geometry Editor
added multiple selection key as a Preference in Menu -> Edit -> Preferences It can be either Shift or Ctrl.
fixed bug in Gerber Object -> Copper Clearing.
added more comprehensive tooltips in Non-copper Clearing as advice on how to proceed.
adjusted make_win32.py file so it will work with Python 3.7 (cx_freeze can't copy OpenGL files, so it has to be done manually)

19.09.2018

optimized loading FlatCAM project by double clicking on project file; there is no need to clean up everything by using the function not Thread Safe: on_file_new() because there is nothing to clean since FlatCAM just started.
added a workspace delimitation with sizes A3, A4 and landscape or portrait format
The Workspace checkbox in Preferences GUI is doing toggle on the workspace
made the workspace app default state = False
made the workspace to resize when units are changed
disabled automatic defaults save (might create SSD wear)
added an automatic defaults save on FlatCAM application close
made the draw method for the Workspace lines 'agg' so the quality of the FC objects will not be affected
added Area constrain to the Panelization Tool: if the resulting area is too big to fit within constrains, the number of columns and/or rows will be reduced to the maximum that still fits is.
removed the Flip command from Panelization Tools because Flipping (Mirroring) should be done properly with the Transform Tool or using the provided shortcut keys.
made Font parsing threaded so the application will not wait for the font parsing to complete therefore the app start is faster

17.09.2018

fixed Measuring Tool not working when grid is turned OFF

added the .ROL extension when saving Machine Code
replaced strings that reference to G-Code from G-Code to CNC Code
added capability to open a project by serving the path/project_name.FlatPrj as a parameter to FlatCAM.py

15.09.2018

removed dwell line generator and included dwell generation in the preprocessor files
added a proposed RML1 Roland_MDX20 preprocessor file.
added a limit of 15mm/sec (900mm/min) to the feedrate and to the feedrate_rapid. Anything faster than this will be capped to 900mm/min regardless what is entered in the program GUI. This is because Roland MDX-20 has a mechanical limit of the speed to 15mm/sec (900mm/min in GUI)

14.09.2018

remade the Double Sided Tool so it now include mirroring of Excellon and Geometry Objects along Gerber. Made adding points easier by adding buttons to GUI that allow adding the coordinates captured by left mouse click + SHIFT key

remade the GUI in Preferences and removed unwanted stretch that was broken the layout.
if for a certain tool, the slots number is zero it will not be displayed
reworked Text to Geometry feature to work in Linux and MacOS
remade the Text to Geometry so font collection process is done once at app start-up improving the performance

09.09.2018

added TEXT ENTRY SUPPORT in Geometry Editor. It will convert strings of True Type Fonts to geometry. The actual dimensions are approximations because font size is in points and not in metric or inch units. For now full support is limited to Windows. In Linux/MacOS only the fonts for which the font name is the same as the font filename are supported. Italic and Bold functions may not work in Linux/MacOS.
solved bug: some Drawing menu entries not having connected functions

28.08.2018

icon changes and menu compress

23.08.2018

added Excellon routing support
solved a small bug that crippled Excellon slot G85 support when the coordinates are with period.
changed the way selection is done in Geometry Editor; now it should work in all cases (although the method used may be computationally intensive, because sometimes you have to click twice to make selection if you do it too fast)

21.08.2018

added Excellon slots support when using G85 command for generation of the slots file. Inspired from the work of @mgix. Thanks. Routing format support for slots will follow.
minor bug solved: option "Cut over 1st pt" now has same name both in Preferences -> Geometry Options and in Selected tab -> Geomety Object. Solves #3
added option to select Climb or Conventional Milling in Gerber Object options Solves #4
made "Combine passes" option to be saved as an app preference
added Generate Exteriors Geo and Generate Interiors Geo buttons in the Gerber Object properties
added configuration for the number of steps used for Gerber circular aperture linear approximation. The option is in Preferences -> Gerber Options
added configuration for the number of steps used for Gcode circular aperture linear approximation. The option is in Preferences -> CNCjob Options

03.07.2018

fixed bug in rotate function that didn't update the bounding box of the modified object (rotated) due of not emitting the right signal parameter.
removed the Options tab from the Notebook (the left area where is located also the Project tab). Replaced it with the Preferences Tab launched with Menu -> Edit -> Preferences
when FlatCAM is used under MacOS, multiple selection of shapes in Editor mode is done using SHIFT key instead of CTRL key due of MacOS interpreting Ctrl+LMB_click as a RMB click
when in Editor, clicking not on a shape, reset the index of selected shapes to zero
added a new Tab in the Plot Area named Gcode Editor. It allow the user to edit the Gcode and then Save it or Print it.
added a fix so the 'preamble' Gcode is correctly inserted between the comments header and the actual GCODE
added Find function in G-Code Editor

27.06.2018

the Plot Area tab is changing name to "Editor Area" when the Editor is activated and returns to the "Plot Area" name upon exiting the Editor
made the labels shorter in Transform Tool in anticipation of Options Tab removal from Notebook and replacing it with Preferences
the Excellon Editor is not finished (not even started yet) so the Plot Area title should stay "Plot Area" not change to "Editor Area" when attempting to edit an Excellon file. Solved.
added a header comment block in the generated Gcode with useful information's
fixed issue that did not allow the Nightly's to be run in Windows 7 x64. The reason was an outdated DLL file (freetype.dll) used by Vispy python module.

25.06.2018

"New" menu entry in Menu -> File is renamed to "New Project"
on "New Project" action, all the Tools are reinitialized so the Tools tab will work as expected

22.06.2018

added export PNG image functionality and menu entry in Menu -> File -> Export PNG ...
added a command to set focus on canvas inside the mouve move event handler; once the mouse is moved the focus is moved to canvas so the shortcuts work immediatly.
solved a small bug when using the 'C' key to copy name of the selected object to clipboard
fixed millholes() function and isolate() so now it works even when the tool diameter is the same as the hole diameter.

Actually if the passed value to the buffer() function is zero, I artificially add a value of 0.0000001 (FlatCAM has a precision of 6 decimals so I use a tenth of that value as a pseudo "zero") because the value has to be positive. This may have solved for some use cases the user complaints that on clearing the areas of copper there is still copper leftovers.

added shortcut "Shift+G" to toggle the axis presence. Useful when one wants to save a PNG file.
changed color of the grid from 'gray' to 'dimgray'
the selection shape is deleted when the object is deleted
the plot area is now in a TAB.
solved bug that allowed middle button click to create selection
fixed issue with main window geometry restore (hopefully).
made view toolbar to be hidden by default as it is not really needed (we have the functions in menu, zoom is done with mouse wheel, and there is also the canvas context menu that holds the functionality)
remade the GUIElements.FCInput() and made a GUIElements.FCTab()
on visibility plot toogle the selection shape is deleted
made sure that on panning in Geometry editor, the context menu is not displayed
disabled App shortcut keys on entry in Geometry Editor so only the local shortcut keys are working
deleted metric units in canvas context menu
added protection so object deletion can't be done until Geometry Editor session is finished. Solved bug when the shapes on Geometry Editor were not transferred to the New_geometry object yet and the New_Geometry object is deleted. In this case the drawn shapes are left in a intermediary state on canvas.
added selection shape drawing in Geometry Editor preserving the current behavior: click to select, click on canvas clear selection, Ctrl+click add to selection new shape but remove from selection if already selected. Drag LMB from left to right select enclosed shapes, drag LMB from right to left select touching shapes. Now the selection is made based on
added info message to be displayed in infobar, when a object is renamed

20.06.2018

there are two types of mouse drag selection (rectangle selection). If there is a rectangle selection from left to right, the color of the selection rectangle is blue and the selection is "enclosing" - this means that the object to be selected has to be enclosed by the selecting blue rectangle shape. If there is a rectangle selection fro right to left, the color of the selection rectangle is green and the selection is "touching" - this means that it's enough to touch with the selecting green rectangle the object(s) to be selected so they become selected
changed the modifier key required to be pressed when LMB is ckicked over canvas in order to copy to clipboard the coordinates of the click, from CTRL to SHIFT. CTRL will be used for multiple selection.
change the entry names in the canvas context menu
disconnected the app mouse event functions while in geometry editor since the geometry editor has it's own mouse event functions and there was interference between object and geometry items. Exception for the mouse release event so the canvas context menu still work.
solved a bug that did not update the obj.options after a geometry object was edited in geometry editor
solved a bug in the signal that saved the position and dimensions of the application window.
solved a bug in app.on_preferences() that created an error when run in Linux

18.06.2018 Update 1

reverted the 'units' parameter change to 'global_units' due of a bug that did not allow saving of the project
modified the camlib transform (rotate, mirror, scale etc) functions so now they work with Gerber file loaded with 'follow' parameter

reworked the Properties context menu option to a Tool that displays more informations on the selected object(s)
remade the FlatCAM project extension as .FlatPrj
rearranged the toolbar menu entries to a more properly order
objects can now be selected on canvas, a blue polygon is drawn around when selected
reworked the Tool Move so it will work with the new canvas selection
reworked the Measurement Tool so it will work with the new canvas selection
canvas selection can now be done by dragging left mouse boutton and creating a selection box over the objects
when the objects are overlapped on canvas, the mouse click selection works in a circular way, selecting the first, then the second, then ..., then the last and then again the first and so on.
double click on a object on canvas will open the Selected Tab
each object store the bounding box coordinates in the options dict
the bbox coordinates are updated on the obj options when the object is modified by a transform function (rotate, scale etc)

15.06.2018

the selection marker when moving is now a semitransparent Polygon with a blue border
rectified a small typo in the ToolTip for Excellon Format for Diptrace excellon format; from 4:2 to 5:2

remade the Measurement tool, there is now a line between the start point of measurement and the end point of the measurement.
renamed most of the system variables that have a global app effect to global_name where name is the parameter (variable)

9.06.2018

reverted to PyQt4. PyQt5 require too much software rewrite
added calculators: units_calculator and V-shape Tool calculator
solved bug in Join Excellon
added right click menu over canvas

6.06.2018 Update

fixed bug: G-Code could not be saved
fixed bug: double clicking a category in Project Tab made the app to crash
remade the bounds() function to work with nested lists of objects as per advice from JP which made the operation less performance taxing.
added shortcut Shift+R that is complement to 'R'
shorcuts 'R' and 'Shift+R' are working now in steps of 90 degrees instead of previous 45 degrees.
added filters in the open ... FlatCAM projects are saved automatically as *.flat, the Gerber files have few categories. So the Excellons and G-Code and SVG.

6.06.2018

remade the transform functions (rotate, flip, skew) so they are now working for joined objects, too
modified the Skew and Rotate comamands: if they are applied over a selection of objects than the origin point will be the center of the biggest bounding box. That allow for perfect sync between the selected objects
started to modify the program so the exceptions are handled correctly
solved bug where a crash occur when ObjCollection.setData didn't return a bool value
work in progress for handling situations when a different file is loaded as another (like loading a Gerber file using Open Excellon commands.
added filters on open_gerber and open_excellon Dialogs. There is still the ability to select All Files but this should reduce the cases when the user is trying to oprn a file from a wrong place.

4.06.2018

finished PyQt4 to PyQt4 port on the Vispy variant (there were some changes compared with the Matplotlib version for which the port was finished some time ago)
added Ctrl+S shortcut for the Geometry Editor. When is activated it will save de geometry ("update") and return to the main App.
modified the Mirror command for the case when multiple objects are selected and we want to mirror all together. In this case they should mirror around a bounding box to fill all.

3.06.2018

removed the current drill path optimizations as they are inefficient
implemented Google OR-tools drill path optimization in 2 flavors; Basic OR-tools TSP algorithm and OR-Tools Metaheuristics Guided Local Path
Move tool is moved to Menu -> Edit under the name Move Object
solved some internal bugs (info command was creating an non-fatal error in PyQt, regarding using QPixMaps outside GUI thread
reworked camlib number parsing (still had some bugs)
working in porting the application from usage of PyQt4 to PyQt4
added TclCommands save_sys and list_sys. save_sys is saving all the system default parameters and list_sys is listing them by the first letters. listsys with no arguments will list all the system parameters.

29.05.2018

modified the labels for the X,Y and Dx,Dy coordinates
modified the menu entries, added more icons
added initial work on a Excellon Editor
modified the behavior of when clicking on canvas the coordinates were copied to cliboard: now it is required to press CTRL key for this to happen, and it will only happen just for left mouse button click
removed the autocopy of the object name on new object creation
remade the Tcl commands drillcncjob and cncjob
added fix so the canvas is focused on the start of the program, therefore the shortcuts work without the need for doing first a click on canvas.

28.05.2018

added total drill count column in Excellon Tool Table which displays the total number of drills
added aliases in panelize Tool (pan and panel should work)
modified generate_milling method which had issues from the Python3 port (it could not sort the tools due of dict to dict comparison no longer possible).
modified the 'default' preprocessor in order to include a space between the value of Xcoord and the following Y
made optional the using of threads for the milling command; by default it is OFF (False) because in the current configuration it creates issues when it is using threads
modified the Panelize function and Tcl command Panelize. It was having issues due to multithreading (kept trying to modify a dictionary in redraw() method)and automatically selecting the last created object (feature introduced by me). I've added a parameter to the app_obj.new_object method, named autoselected (by default it is True) and in the panelize method I initialized it with False. By initializing the plot parameter with False for the temporary objects, I have increased dramatically the generation speed of the panel because now the temporary object are no longer ploted which consumed time.
replaced log.warn() with log.warning() in camlib.py. Reason: deprecated
fixed the issue that the "Defaults" button was having no effect when clicked and Options Combo was in Project Options
fixed issue with Tcl Shell loosing focus after each command, therefore needing to click in the edit line before we type a new command (borrowed from @brainstorm
added a header in the preprocessor files mentioning that the GCODE files were generated by FlatCAM.
modified the number of decimals in some of the line entries to 4.
added an alias for the millholes Tcl Command: 'mill'

27.04.2018

modified the Gerber.scale() function from camlib.py in order to allow loading Gerber files with 'follow' parameter in other units than the current ones
snap_max_entry is disabled when the DRAW toolbar is disabled (previous fix didn't work)
added drill count column in Excellon Tool Table which displays the total number of drills for each tool
added a new menu entry in Menu -> EDIT named "Join Excellon". It will merge a selection of Excellon files into a new Excellon file
added menu stubs for other Excellon based actions
solved bug that was not possible to generate film from joined geometry
improved toggle active/inactive of the object through SPACE key. Now the command works not only for one object but also for a selection

26.05.2018

made conversion to Python3
added Rtree Indexing drill path optimization
added a checkbox in Options Tab -> App Defaults -> Excellon Group named Excellon Optim. Type from which it can be selected the default optimization type: TS stands for Travelling Salesman algorithm and Rtree stands for Rtree Indexing
added a checkbox on the Grid Toolbar that when checked (default status is checked) whatever value entered in the GridX entry will be used instead of the now disabled GridY entry
modified the default behavior on when a line_entry is clicked. Now, on each click on a line_entry, the content is automatically selected.
snap_max_entry is disabled when the DRAW toolbar is disabled

24.05.2015

in Geometry Editor added a initial form of Rotate Geometry command in toolbar
changed the way the geometry is finished if it requires a key: before it was using key 'Space' now it uses 'Enter'
added Shortcut for Rotate Geometry to key 'Space'
after using a tool in Geometry Editor it automatically defaults to 'Select Tool'

23.05.2018

Added key shortcut's in FlatCAMApp and in Geometry Editor.

FlatCAMApp shortcut list: 1 Zoom Fit 2 Zoom Out 3 Zoom In C Copy Obj_Name E Edit Geometry (if selected) G Grid On/Off M Move Obj

N New Geometry R Rotate S Shell Toggle V View Fit X Flip on X_axis Y Flip on Y_axis ~ Show Shortcut List

Space: En(Dis)able Obj Plot Ctrl+A Select All Ctrl+C Copy Obj Ctrl+E Open Excellon File Ctrl+G Open Gerber File Ctrl+M Measurement Tool Ctrl+O Open Project Ctrl+S Save Project As Delete Delete Obj'''

Geometry Editor Key shortcut list: A Add an 'Arc' C Copy Geo Item G Grid Snap On/Off K Corner Snap On/Off M Move Geo Item

N Add an 'Polygon' O Add a 'Circle' P Add a 'Path' R Add an 'Rectangle' S Select Tool Active

~ Show Shortcut List Space: Rotate Geometry Enter: Finish Current Action Escape: Abort Current Action Delete: Delete Obj

22.05.2018

Added Marlin preprocessor
Added a new entry into the Geometry and Excellon Object's UI: Feedrate rapid: the purpose is to set a feedrate for the G0 command that some firmwares like Marlin don't intepret as 'move with highest speed'
FlatCAM was not making the conversion from one type of units to another for a lot of parameters. Corrected that.
Modified the Marlin preprocessor so it will generate the required GCODE.

21.05.2018

added new icons for menu entries
added shortcuts that work on the Project tab but also over Plot. Shorcut list is accesed with shortcut key '~' sau '`'
small GUI modification: on each "New File" command it will switch to the Project Tab regardless on which tab we were.
removed the global shear entries and checkbox as they can be damaging and it will build effect upon effect, which is not good
solved bug in that the Edit -> Shear on X (Y)axis could adjust only in integers. Now the angle can be adjusted in float with 3 decimals.
changed the tile of QInputDialog to a more general one
changed the "follow" Tcl command to the new format
added a new entry in the Menu -> File, to open a Gerber with the follow parameter = True
added a new checkbox in the Gerber Object Selection Tab that when checked it will create a "follow" geometry
added a few lines in Mill Holes Tcl command to check if there are promises and raise an Tcl error if there are any.
started to modify the Export_Svg Tcl command

20.05.2018

changed the interpretation of the axis for the rotate and skew commands. Actually I reversed them to reflect reality.
for the rotate command a positive angle now rotates CW. It was reversed.
added shortcuts (for outside CANVAS; the CANVAS has it's own set of shortcuts) Ctrl+C will copy to clipboard the name of the selected object Ctrl+A will Select All objects "X" key will flip the selected objects on X axis "Y" key will flip the selected objects on Y axis "R" key will rotate CW with a 45 degrees step
changed the layout for the top of th Options page. Added a checkbox and entries for parameters for skew command. When the checkbox is checked it will save (and load at the next startup of the program) the option that at each CNCJob generation (be it from Excellon or Geometry) it will perform the Skew command with the parametrs set in the nearby field boxes (Skew X and Skey Y angles). It is useful in case the CNC router is not perfectly alligned between the X and Y axis
added some protection in case the skew command receive a None parameter
BUG solved: made an UGLY (really UGLY) HACK so now, when there is a panel geometry generated from GUI, the project WILL save. I had to create a copy of the generated panel geometry and delete the original panel geometry. This way there is no complain from JSON module about circular reference.
removed the Save buttons previously added on each Group in Application Defaults. Replaced them with a single Save button that stays always on top of the Options TAB
added settings for defaults for the Grid that are persistent
changed the default view at FlatCAM startup: now the origin is in the center of the screen

19.05.2018

last object that is opened (created) is always automatically selected and the name of the object is automatically copied to clipboard; useful when using the TCL command :)
added new commands in MENU -> EDIT named: "Copy Object" and "Copy Obj as Geom". The first command will duplicate any object (Geometry, Gerber, Excellon). The second command will duplicate the object as a geometry. For example, holes in Excello now are just circles that can be "painted" if one wants it.
added new Tool named ToolFreeformCutout. It does what it says, it will make a board cutout from a "any shape" Gerber or Geometry file
solved bug in the TCL command "drillcncjob" that always used the endz parameter value as the toolchangez parameter value and for the endz value used a default value = 1
added preprocessor name into the TCL command "drillcncjob" parameters
when adding a new geometry the default name is now: "New_Geometry" instead of "New Geometry". TCL commands don't handle the spaces inside the name and require adding quotes.
solved bug in "cncjob" TCL command in which it used multidepth parameter as always True regardless of the argument provided
added a checkbox for Multidepth in the Options Tab -> Application Defaults

18.05.2018

added an "Defaults" button in Excellon Defaults Group; it loads the following configuration (Excellon_format_in 2:4, Excellon_format_mm 3:3, Excellon_zeros LZ)
added Save buttons for each Defaults Group; in the future more parameters will be propagated in the app, for now they are a few
added functions for Skew on X axis and for Skew on Y menu stubs. Now, clicking on those Menu -> Options -> Transform Object menu entries will trigger those functions
added a CheckBox button in the Options Tab -> Application Defaults that control the behaviour of the TCL shell: checking it will make the TCL shell window visible at each start-up, unchecking it the TCL shell window will be hidden until needed
Depth/pass parameter from Geometry Object CNC Job is now in the defaults and it will keep it's value until changed in the Application Defaults.

17.05.2018

added messages box for the Flip commands to show error in case there is no object selected when the command is executed
added field entries in the Options TAB - > Application Defaults for the following newly introduced parameters: excellon_format_upper_in excellon_format_lower_in excellon_format_upper_mm excellon_format_lower_mm

The ones with upper indicate how many digits are allocated for the units and the ones with lower indicate how many digits from coordinates are alocated for the decimals.

[ Eg: Excellon format 2:4 in INCH excellon_format_upper_in = 2 excellon_format_lower_in = 4 where the first 2 digits are for units and the last 4 digits are decimals so from a number like 235589 we will get a coordinate 23.5589 ]

added Radio button in the Options TAB - > Application Defaults for the Excellon_zeros parameter After each change of those parameters the user will have to press "Save defaults" from File menu in order to propagate the new values, or wait for the autosave to kick in (each 20sec). Those parameters can be set in the set_sys TCL command.

15.05.2018

modified SetSys TCL command: now it can change units
modified SetSys TCL command: now it can set new parameters: excellon_format_mm and excellon_format_in. the first one is when the excellon units are MM and the second is for when the excellon units are in INCH. Those parameters can be set with a number between 1 and 5 and it signify how many digits are before coma.
added new GUI command in EDIT -> Select All. It will select all objects on the first mouse click and on the second will deselect all (toggle action)
added new GUI commands in Options -> Transform object. Added Rotate selection, Flip on X axis of the selection and Flip on Y axis of the selection For the Rotate selection command, negative numbers means rotation CCW and positive numbers means rotation CW.
cleaned up a bit the module imports
worked on the excellon parsing for the case of trailing zeros. If there are more than 6digits in the coordinates, in case that there is no period, now the software will identify the issue and attempt to correct it by dividing the coordinate further by 10 for each additional digit over 6. If the number of digits is less than 6 then the software will multiply by 10 the coordinates

14.05.2018

fixed bug in Geometry CNCJob generation that prevented generating the object
added GRBL 1.1 preprocessor and Laser preprocessor (adapted from the work of MARCO A QUEZADA)

13.05.2018

added postprocessing in correct form
added the possibility to select an preprocessor for Excellon Object
added a new preprocessor, manual_toolchange.py. It allows to change the tools and adjust the drill tip to touch the surface manually, always in the X=0, Y=0, Z = toolchangeZ coordinates.
fixed drillcncjob TCL command by adding toolchangeZ parameter
fixed the preprocessor file template 'default.py' in the toolchange command section
after I created a feature that the message in infobar is cleared by moving mouse on canvas, it generated a bug in TCL shell: everytime mouse was moved it will add a space into the TCL read only section. Now this bug is fixed.
added an EndZ parameter for the drillcncjob and cncjob TCL commands: it will specify at what Z value to park the CNC when job ends
the spindle will be turned on after the toolchange and it will be turned off just before the final end move.

Previously:

added GRID based working of FLATCAM
added Set Origin command
added FilmTool, PanelizeTool GUI, MoveTool
and others

24.04.2018

Remade the Measurement Tool: it now ask for the Start point of the measurement and then for the Stop point. After it will display the measurement until we left click again on the canvas and so on. Previously you clicked the start point and reset the X and Y coords displayed and then you moved the mouse pointer wherever you wanted to measure, but moving the mouse from there you lost the measurement.
Added Relative measurement on the main plot
Now both the measuring tool and the relative measurement will work only with the left click of the mouse button because middle mouse click and right mouse click are used for panning
Renamed the tools files starting with Tool so they are grouped (in the future they may have their own folder like for TCL Commands)
Commented some shortcut keys and functions for features that are not present anymore or they are planned to be in the future but unfinished (like buffer tool, paint tool)
minor corrections regarding PEP8 (Pycharm complains about the m)
solved bug in TclCommandsSetSys.py Everytime that the command was executed it complain about the parameter not being in the list (something like this). There was a missing “else:”
when using the command “set_sys excellon_zeros” with parameter in lower case (either ‘l’ or ‘t’) now it is always written in the defaults file as capital letter
solved a bug introduced by me: when apertures macros were detected in Excellon file, FlatCam will complain about missing dictionary key “size”. Now it first check if the aperture is a macro and perform the check for zero value only for apertures with “size” key
solved a bug that didn't allowed FC to detect if Excellon file has leading zeros or trailing zeros
solved a bug that FC was searching for char ‘%’ that signal end of Excellon header even in commented lines (latest versions of Eagle end the commented line with a ‘%’)

============================================ This fork features:

Added buttons in the menu bar for opening of Gerber and Excellon files;
Reduced number of decimals for drill bits to two decimals;
Updated make_win32.py so it will work with cx_freeze 5.0.1
Added capability so FlatCAM can now read Gerber files with traces having zero value (aperture size is zero);
Added Paint All / Seed based Paint functions from the JP's FlatCAM;
Added Excellon move optimization (travelling salesman algorithm) cherry-picked from David Kahler: https://bitbucket.org/dakahler/flatcam
Updated make_win32.py so it will work with cx_freeze 5.0.1
Corrected small typo in DblSidedTool.py
Added the TCL commands in the new format. Picked from FLATCAM master.
Hack to fix the issue with geometry not being updated after a TCL command was executed. Now after each TCL command the plot_all() function is executed and the canvas is refreshed.
Added GUI for panelization TCL command
Added GUI tool for the panelization TCL command: Changed some ToolTips. ============================================

Previously added features by Dennis

"Clear non-copper" feature, supporting multi-tool work.
Groups in Project view.
