Export to blender

Hello

I’m having problems when exporting to Blender

The mesh has folds, here is an image of the Blender viewport:
It’s also like this in the render

How can I fix this?

Thanks

What render are you talking about? Blender or Rhino Render?

What file format are you exporting to?

Please share the 3dm file with this object in for further investigation.

Have you tried import_3dm?

Is there already a version of import_3dm for blender 4.2?

Thanks for your help

Yes, already since v0.0.12. The currently released version v0.0.13 also works in Blender 4.2. You can get it via the link I shared in my previous response.

with: import_3dm for blender 4.2 it decreased a lot but you can still see it.

here is the file:

MESH.3dm (5.9 MB)

thanks

You may want to select the object and do object > shade smooth in Blender. Looks otherwise fine to me in both Blender and Rhino Raytraced
