Can't split surface with projected curve

Hi all,

I have problem with splitting one surface patch with projected polyline. There were several surfaces on which this polyline was projected and on only this one I’m unable to do so.
Error is - Split failed, objects may not intersect or intersections may not split object.

I uploaded the file to my drive:

Any idea what to do?
Thank you

Hi Viktor- your curve does not make it to the edge of the surface -


ExtendCrvOnSrf will get it there.


Thank you Pascal :+1:
