Summary0002896: More advanced Draft WB Bspline editing
DescriptionI'm trying to edit a Bspline and certain points seem to be locked it - I can't move them, can't remove them, they just sit there and I can't do nothing about it.

Here's a video demonstrating the problem:

@abdullah do you mind weighing in on this thread since this involves bsplines? Thanks!

This is for Draft BSpline. I generally work with Sketcher BSpline.

Draft is written in Python. I barely can read Python. Sketcher is written in c++. I can code c++.

Sorry but I am not the right person for commenting on this ticket.

Can I use Sketcher to manipulate the bsplines too? Maybe such problem won't happen there? Is that funcionaliy available in 0.17 (freecad-daily) release or do I need something special?

I had a very quick look at the thread above. It seems to me that what you want to do is generate some profiles using bsplines and then loft the profiles to generate a shape.

This can be done with the BSplines in the Sketcher and loft with part design.

BSplines support in the sketcher was merged quite recently (January/February 2017). I see you use linux, then I would either use the daily-build or compile from source.

Currently those Sketcher BSplines have some limitations: No knots editing, no knot multiplicity setting (yes you can set the weights of the poles). If you can live with that, then it may be an option for you.
