My problem is that I can not trim this surface
The cutting object is the surface, and the objects to trim are panels.
I use network, and sweep but neither do not work.
What would be problem??? I don't understand.

Next time try to compress your 3dm files !
1.8 megas = 307 kb :)

ohhh I'm sorry!
I think realise the mistake...the curves didnt joint.
Sorry again.

Hi Andras - yes it looks like your cutting surface is actually 2 pieces which don't quite line up with one another, that's why they won't cut those panels.

You'll need to reconstruct the lower one so that it follows the same edge curve as the upper one, so that it can divide the panel into 2 pieces.

It looks like a cool project you are working on!
