Trim surface with curve

[kvi]

Hi

Im having trouble trimming off the surface outside my curve, on this surface.

I have made the surface as a patch, from the curve but the “automatic trim” didnt work.

Any ideas?

And also maybe a better way of making the surface.
The patch function gives me a more flat surface than I would like.

Sweep, loft etc.???

Can you post a file please?
It could be a problem with the curve or with a command option.

Hi John

Sure, here you go.

There’s no curve in that file and now it’s a polysurface so the game has changed.
If it’s going to be a polysurface, extrude your curve into a ribbon surface that intersects the polysurface, then check the normals and use a Boolean.
I’m making a lot of assumptions there.

Thanks.
I’m not sure what I’m doing as I am new to this game

I started out with a imported frame, which I used extractisocurve on, to get some geometry to work off.
Maybe there is a better way of doing it?

I would like to upholster the frame, so to say.
