I created one complex geometry of plane surface, but it had a lot of gaps between each plane surface. So I converted the geometry into mesh, and I filled the gaps. But I wanted the filled mesh geometry to have surfaces rather than mesh. So I converted the mesh geometry into NURBS surfaces. However, the geometry has had a lot of NURBS surfaces rather than plane surface. I was just wondering if the NURBS surfaces could be changed to plane surface without the gaps.
