Hi @user246
It could be a multitude of different issues. The best you can do is to export the curves and surfaces you have so far to a new Rhino file (export selected), post it here and I’m sure someone will take a look!

Hello - make the side surfaces with say a Sweep2 or loft of the two long curves

Patch is generally a poor first choice for a primary surface, especially one that has four clear edges. Please see
