Re: Draft Workbench - why is my pattern so faint?

I seem to remember a discussion about the "Number of decimals" setting and how it should not restrict user input (as it does here*). I cannot find it now. Was a conclusion ever reached? I remember there was at least one such discussion, probably more than one. Couldn't find it either. I recommend s...

Re: Error in Mirror if contents are not visible

The interesting stuff appears to be happening in _getTopoShape() routine found in PartFeature.cpp.

The problem is, it's :shock: :shock: :shock: :shock: long. And complicated.

Small remark: the order of arguments in the Python wrapper is different to the C++ function and different to the slerp() function of the Rotation class. Could we harmonize it to be more consistent?
Yes, I think I just screwed this up :oops:

The interpolation takes a helical path. * as pow() method in python, to interpolate between origin and the placement * as sclerp() method in python, to i...
