I get degenerated bezier surfaces in my meshing because of having triangular patches in rhino model. For my solver, I need all my beziers be quadrilateral and can’t read triangular ones. So, it generates degenerated beziers in reading the model and effects my results very badly. Is there any way to convert those degenerated beziers to quadrilateral ones? Thanks

To find out which beziers are problematic, when I am reading the geometry I check singularity of the sides of each bezier using bezier.Issingular(0-4)! Then, I need a way to create quadrilateral beziers manually.
