I am using 3dconnexion SpaceNavigator spaceball. That is working correctly for me within both versions 19 and 20 of FreeCAD. I had to look at my Linux system's syslog for an unrelated issue (disk drive flagged by SMART), I noticed something I did not expect: spacenavd is flooding my syslog with mess...

... pressing the "simulate" button on the controller prior any job. :) ... (snip) Doing a simulate, without saving the gcode instruction sets generated for that simulation , implies the control will re-calculate at every run ... while cutting . That is not safe because calculation glitche...

Thank you for responding, drmacro. They see it as a major refactor of nontrivial code that is not currently on their radar. Your response suggest you have much awareness with the OCCT development activities. Would you not say that their prioritizing of such a request is skewed because they are focus...

Thank you for responding, drmacro. Actually adding the dressup things like the under cut is best done in the sketch. I will partly acknowledge that undercuts should be included in a sketch of the cross-section of a part. If a particular undercut/chamfer/fillet is standard practice on a given section...

Thank you for responding, chrisb. ... In this case you have to make a Groove ... (snip) I acknowledge the power and flexibility of Groove, since it uses a task-specific sketch. I also looked at trying to identify the sketch constraints that I have to "suspend", in order to modify the exist...

Trying to take a stab at "retrofitting" the PartDesign Chamfer code to offer the additional option for Undercuts . I located " TaskChamferParameters.cpp ". That led me to " FeatureChamfer.cpp ". This last identified the need for " mkChamfer.AddDA " ... which I...

I'm trying to find a function to perform an edge feature, similar to fillet or chamfer, but which does an undercut instead. Undercuts are a common design feature when a turned surface is intended to be a positioning surface for assemblies, to ensure faces are flush and no interference from leftover ...

I looked around and could not find references providing details on the level of compliance of the generated STEP file that the engine used by FreeCAD can provide. I did confirm that the generated STEP file is reporting itself as formatted to ISO 10303-214 . However, three is no indication if that is...

... with all the same dimensions/art but different names on each one. ...(snip) Is it possible that what is being asked for is the ability to create a library of stored fixture setups ? If such were available, the user could be offered to use one of two options: "new", which would initiat...

Thank you, chrisb, for replying. I was thinking that having a "freeze" attribute would protect geometry ... a) from being accidentally selected/modified, on the one hand, or b) from being manipulated by scripts that might auto-select for action, not knowing that those items are not "a...
