Trying to rebuild a double curve surface, need some advice

roof test.3dm (4.6 MB) 2

Hello, I am given a surface and ask to parametrize this double curve surface. I first tried to find the logic to rebuild this surface in rhino. I tried to sweep and patch through the diagonal line and the four perimeter lines. But the curvature is not quite right. Then I sub-divided the surface into 8, and individual patch them, the result curvature is right, but the surface is no long one surface and lost its smoothness. I have attached my rhino file, hope somebody can shine some lights on this question.

Hi, there.
Do you mind to tell me how can I move this thread to the rhino category? I am quite new to this forum. Sorry for the inconvenience.

Hello, thanks for your help. Could you export a file with lower version? I am with rhino 6 now.

Hey @jiaxin.zhao18,

This conversation is already in the Rhino category. But in the future, just edit your original (first) post - there you can change the category.

No problem.
Thanks for pointing that out.
