Hi everyone,

I tried Ixlrlxi aka 600v aka SketchUp god SubD tutorial (https://3dwarehouse.sketchup.com/model/276574de12315fa9174441d8b698e801/tutorial-car-model-before-subdivision-and-after)

Well, the orange side is the original but when I tried to SubDivide the test part, the mesh looked weird and definitely not as it is supposed to be.

Any idea why? Can you please help me figure this out.
