Hi there, I contributed the plunge angle feature half a year ago, in commit c862fc006. I also now noticed that it was taken out again, with commit 84b3617c97, "PATH: Delete misplaced and unused files"... It seems the code is still there, but commented out in now unused routines, it was mos...

a Part and a Body ar local coordinate systems. So if you transform one of thse it does not affect the features beneath at all, they are at the exact same location in the local coordinate system as before. How would I transform a sub-object of a Body? The "Placement" property is not availa...

Hi there, apparently, there is now the concept of a "Part" and a "Body" in FreeCAD. (I have not quite understood how/why to use them and why only some objects are below such a hierarchy). This seems to create a problem for the Path Profile operation: Previously, I could easily ro...

Ok, done:

Meanwhile I found a much cleaner way to detect when the generated circle is wrong: Just look at the generated coordinates directly instead to compare them to some arbitrarily defined small value, see the PR.

Something wrong with the patch? Should I make a pull-request? Or is this not necessary anyway, as the "OCC native" method is never used by anyone anyway?

Another thing I noticed: Sometimes Profile inserts a full circle at tangential lines attached to an arc, I guess there is some numerical precision issue there: I've noticed this as well but I don't know why it occurs. The libarea algorithm doesn't seem to have the problem and is generally more reli...

But the lack of any decent topology information exposed to the Python layer makes all such endeavors quite painful. Does anyone know more about that, or has some hints for me? Can you elaborate on this a bit? I don't understand what you mean. Well, basic adjacency information: For example, given a ...

This is already implemented. Operations have a property called 'user label' that is used exactly this way. It doesn't have an input in the task panel yet, unfortunately. Perfect! Another thing I noticed: Sometimes Profile inserts a full circle at tangential lines attached to an arc, I guess there i...

This looks good to me. Works as described. I see no reason not to accept this pull request. Thank you! Glad you like it! I see it is merged now in the github repo, thanks. Regarding the labels on the profile operations [...] Anyway, is it helpful to change the labels like this or just annoying? I t...

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 com...
