Fix Mesh/Surface

Hello, I export from Rhino to Blender a .obj file but my faces/mesh/whatever the name is,is not correct. How can I fix it

can you give some more detail here?

what is not correct?

can you post your file?

I think it is not correct because in Rhino it does not look like that and I when I export it as an .abc (I did a bend animation) it does not respond well with the light of the environment (in the back side)

you have given me nothing that I can help you with…

file? images?, screen shots,? a recording of your animation?

Anything that actually shows your problem?

help me help you…
