**Describe the bug** When using curves with unclamped knotvector, if you try to insert a knot near the right end of knotvector (more precisely, try to insert `u_bar` which is...
Hi, tangent and normal operations does not work with nurbs, please check the 5.3.1 code. (return empty tuple) 5.2.10 seams that does not suffer of the issue. Thank you and...
I have some troubles. First, I used Nurbs-Python to create 3D nurbs curves and planned to export them, but found that 3D curves could not be exported to 3dm format...
**Describe the bug** u,v, parametric values of a closed Bspline surface do not appear to correspond with the anticipated model geometry. This happens on a B-spline-with-knots surface exported by the...
**Describe the bug** I have several nurbs curves and they all compare equal to each other, which they shouldn't. The issue seems to be [here](https://github.com/orbingol/NURBS-Python/blob/5.x/geomdl/abstract.py#L367), where `self._precision` is 18 and...

**Describe the bug** I used `knot_insertion` to split a NURBS curve, then tried to use `knot_removal` to merge the two parts again. The output was different from the original: the...
It looks like there is a problem with the remove knot implementation. I'd like to investigate it a bit more and fix it. However, I don't want to block the...
This is a replacement for PR #121, which ended up having a conflicting branch name. It doesn't look like it's possible to substitute the submitted branch within the GitHub system....
