Hello, I actually have this situation. But I’m in a dilemma. When I select “Weld Angle” this happens with the texture, but when I remove the Weld Angle, the final geometry in sketchup has visible lines. If I send the model back to my client who uses Sketchup, he will complain. Is there a way to use the “Weld Angle” without messing up the faces?
Here’s a sample file:
ImportSKP.skp (2.7 MB)
I need to import this in Rhino, model other things, then export to SKP again for my client.
And need the objets to return smooth as they were when he sent me. How do I do this? 
This is the config I use to make it smooth, but bugged.
