Re: A Path command for circular holes and some questions

It seems most of my issues with Profile went away again with the current master. Two little things remain: When opening a saved file, all Profile operations are suddenly called "(TC)", "(TC)001". The other small annoyance is that the label strings in the task panel are almost completely hidden, unle...

Re: A Path command for circular holes and some questions

I would call it a profile. The tool is only clearing the interior because either the radius of the tool is over half the radius of the hole or the depth goes all the way through or both. Profiling an interior face this way is very useful even if the hole is blind for the reasons noted (surface fini...

Re: A Path command for circular holes and some questions

Do you think the implementation could be extended as part of the Path Profile operation? In other words should it be possible to do a 'spiral descent' on any shaped profile that would avoid the plunge at each level? I guess I would think of this as more of a pocket than a profile, right? The idea i...

A Path command for circular holes and some questions

Hi all, I made a simple Path command to make circular holes (larger than the tool diameter) by helical milling motions. I used to do something similar with custom scripts in HeeksCNC, but as the Path functionality of FreeCAD is maturing I think I can finally do all my stuff in FreeCAD directly! Plea...

Re: Ramp feature for profile (patch included)

So if you have a selected edge you need iterate all faces in the document object and test all edges of the faecs with the isSame/isPartner/isEqual methods to the selected one. I got a new GUI command for helix drills working that way. It really is not topology information though - I still have to l...

OK - I see. isSame()/isEqual() was the thing I missed, I tried to compare objects via Python equality/identity, but apparen...

Re: Ramp feature for profile (patch included)

I am terribly sorry, for missing your firs post, without giving you a big hug and welcome to the FreeCAD forum :D Thanks for the warm welcome! What I initially wanted to do next was a command to make circular drill holes (larger than the tool) with multiple helix motions. However, I have a hard tim...

Re: Ramp feature for profile (patch included)

i was wondering if you knew about this helix and ramp feature in this commit c81a012 Ah, cool - I was not aware, I will have a look. For others interested: You do not need to compile a whole FreeCAD, my changes only touch two python files, https://github.com/dev-at-stellardeath-org/FreeCAD/blob/cb5...

Ramp feature for profile (patch included)

Dear all, in case anyone is interested, I made a small patch to (optionally) add ramping to the PathProfile Command. There is a new property "Ramp Angle" with which the downwards angle of the ramp can be specified. See https://github.com/dev-at-stellardeath-org/FreeCAD/tree/path_profile_ramp_angle K...
