First of all, I am new to the software Rhino. What I am trying to do is to create NURBS surface from 4 curves (Each opposite side has the same curve parametrization- same number of control points and degree).
When I use “sweep rails”, the surface is generated with NURBS elements intersecting the boundaries (for my purposes, the lines should not intersect). This seems like a simple problem but I could not figure out a way to form a NURBS surface with no lines intersecting any lines.
Attached are the four curves and the generated NURBS surface with intersecting lines. res1.pdf (15.9 KB)
Later on, I am interested in the analysis of the surface using isogeometric analysis.
I appreciate any help!
