I'm almost sure, my question is a dumb one and the underlying problem is easy to solve...
I've drawn a planar wire and now I'd like to modify it (moving/adding/removing corner points etc.) using the Edit tool.
However, other than in any help/screenshot/tutorial video I've found so far, the point handles are white here with me instead of black as with others and I can't seem to modify anything. I've tried shift/ctrl-clicking and dragging on open as well as closed wires, and many other things, but nothing worked so far.
While I'm comfortable with the Sketcher and many other functions of FreeCAD meanwhile, I'm turning round in circles for hours now and it feels like I'm missing something really basic. Please bear with me!
What is my mistake?
Thank you very much!
