Re: Flatpak version of FreeCAD flickering on Fedora 38 and 39

You can make FreeCAD run natively on wayland. You have to compile yourself and use a libcoin that does NOT try to initialize glx (as that is an X11 extension and leads to core dump when running under wayland), and of course your Qt needs to support wayland. It is definitely useable but not completel...

Re: Getting consistent cutting mode : climb/conv

I would certainly like to see consistent climb/conv cutting mode throughout each operation. [...] At the very least I would be nice to have consistent cutting direction on a simple pocket shape. I suspect that can be done without too much difficultly once there is understanding of how the libarea c...

Re: Getting consistent cutting mode : climb/conv

As it seems there is breakage of existing Path Jobs already, I wonder if this would be a good moment to clean up the CW/CCW and climb/conv mess? IMO for operations like profile, what should be specified is climb vs. conventional milling, and not the direction of travel, which would result in climb c...

Re: (RESOLVED) Profile Operation (Path workbench) only does outside, not inside of shape

You can also select the bottom face, in combination with "process holes" it generates path inside and outside (russ' test file)

Deburr operation

While looking at some problems in Path Profile operation, i noticed that Deburr uses a different method to generate offset polylines. In my naive imagination, Deburr is more or less Profile with some added sugar for tool height calculation. Does that matter in practive? Maybe. Path Profile uses arcs...

Re: Profile cut direction reverses with extra offset != 0 and compensation off

It took a while, but I prepared a PR and (rudimentary) unit tests for Path Profile.

Re: Profile cut direction reverses with extra offset != 0 and compensation off

I'm pretty sure this https://github.com/FreeCAD/FreeCAD/blob/master/src/Mod/Path/Path/Op/Profile.py#L355 is the offending location, but I'm unsure of the rationale why it is reversing cut direction if compensation is off. Seems this is done deliberately, and with extra offset = 0, cut direction is a...

Re: Profile cut direction reverses with extra offset != 0 and compensation off

If somebody can reproduce this and confirm this is indeed not the intended behaviour I will try and fix it. Thanks.

The discrepancy of reversed path with the "CW/CCW" setting messes up the LeadIn/LeadOut dressup and possibly other stuff too.
