Implementation of follow me/sweep (by Rune)
Hi, I think it would be nice if not necessary to have some sweep/follow me method for more sophisticated shapes (screws) or sculpted surfaces. Any thoughts on how this could be coded/accopmplished?

Any ideas of how to go about this? It's also related to question

Anyone on Sweep/Follow me (by Rune)
Jonathan and others.
I've been using solvespace for a year now with some success for 3D printing. However I constantly have to redraw in another cad when a sweep is needed. (Threads, springs irregular shapes etc.)
If only a sweep/follow me function could be implemented it would be a complete CAD program.
What would it take to implement a function that creates a solid from sweeping a sketch along a spline?
Best regards
Rune

While I agree its a needed feature (eventually), it is non trivial. And on the machining side, modeling threads is completely unneeded (so I've spent 0 time thinking about it).

I'm not sure what Jonathan's personal needs are.

Thanks for the reply. The motivation for the requirement is this exoskeleton project: http://mecfes.wikispaces.com/Free+Omega where sweeps are necessary. Since we want to use FOSS tools for this opensource project solvespace could be just perfect as it can also simulate the dynamics. However despite numerous attempts for workarounds, the lack of extrusion along a curve remains a serious limitation.
I think it's a real pitty, otherwise it would have been superior to the heavy and huge cad programs out there.

We are planning to reimplement SolveSpace's NURBS backend using, most likely but unfortunately, OpenCASCADE. As you all know OpenCASCADE is truly disgusting, but also probably our best chance to get a very good NURBS backend.

This will probably take a few months to do, though. I will keep you updated.
