Delete triangulation lines permanently (make a hole) within a surface

Hi
Is there a way to delete triangulation lines permanently (make a hole) within a surface. For example delete triangulation lines inside a reservoir (Pond) embankment

Hi @shashimanandhar1417,

It seems like what you’re looking for is to create a hide boundary. Deleting lines won’t make a hole because the surface will be re-triangulated. If you want to work with surface boundaries, there are some nodes in the Camber package that will help.
