Corrupted srf

Hi,

I'm trying to cut a given srf using a crv.

Depending the srf I use I have correct or wrong result. I know Grasshopper is not the right software to do these stuff, but probably I'm doing something wrong or there is a way to fix the srf.

On the image below you can see that the white crv doesn't cut the red srf.

Thank you for your help!

It seems your curve has two parts which are not connected.

'Project' is producing two results from one input curve; in other words, a curve with a gap in it. I tried several things, all failed, so agree with the thread title - "Corrupted srf". Mysterious.

I guess I have to give up :(

I know, that's why I put wrong on that crv... but I can't understand why

Just remake the surface - try rebuilding it or making it with the edges via edge surface, patch, or network surface.

This worked for me.

Very similar surface, off by ~2 mm in places:

I guess yours is a check on the similarity of the srf.

My issue is that the srf is a given srf, that could have a bumb in the middle and I cannot have the same srf using just edge srf.

At the moment I will use this strategy because, as you noted, there is no difference.

probably the best way is to subdivide the original srf in n parts and use those with patch.

Thanks!

If there is a lot of variation in the surface (bump in the middle) you might also try and contour the surface with a density appropriate to the bumps and then loft those contours.
