Hi VeroniQ,

I already read your blog, excellent work! Thank you !

But it's not quit solving my problem.

I want to have the model as true as posible, so I have an .obj of the OEM manufacturer VELUX, that cannot be 'mount' to a vertical wall. Must be angled.

Besides I already designed the roof (very complex) with the 3D generator, meaning I had to design it your way all over again.

Is there really no way to cut objects, or to at least make them invisible partially?
