Add B-Spline/ NURBS visualization capability.
Direct visualization of NURBS --no discretization necessary!. NURBS is already a standard in computer graphics and the future of FEA (isogeometric analysis).
A merge request for rational Bezier cells has been submitted to VTK.
We hope it will be merged in VTK next version ( 9.0 ), but you can already use it from the merge request branch.

Would you be willing to pay to have a plugin that can read STEP, IGES, 3dm file ?
It's been four years and this is the second-highest-voted suggestion. Can you not even add quadratics, <i>which is part of the VTK standard</i>?
