Curved roof Issue


I have an issue trying to recognize a curved roof.
I have modelled a new space into rhino that has a curved roof but when i select the geometries using the pollination tool, it gives me an error with “Non-planar surfaces”. See attachment:

Can someone help me to understand how to make pollination recognize these kind of spaces please ?

Thank you :slight_smile:


sorry but i have finally sort the issue after watching an old video where Mostapha explained how to use the Convert command into rhino.
That worked perfectly!

Thank you anyway,

I just recorded a video for you:


Thank you. That is helpful too.

I have watched this video to solve it as well:

Thank you.
