if I convert the surface to other data format?

if you mesh the torus maybe you can unweld the edge rings where those curves are?

Unweld mesh edges by indices

Hi everyone! I need to trim a mesh on specified edges, I tried creating trimming solid (mesh/brep) in several ways but it doesn’t work well. I think that the easiest way is to unweld the mesh at some edges selected by indices and then explode the mesh without unweld it again, but there isn’t any component in gh to do that operation, you can only unweld a mesh by a range of angles. In rhino it works with “unweld mesh edges + explode”, but you have to select the edges one by one with the mouse, …

How can I split mesh by edges?

Cut Cut V0.gh (18.0 KB) So, I have a Pikachu, I like to split it into two parts, the bun and the body. Now I have the cutter edges as lines and also indexes of the edges. How can I split the mesh with these two data? I can do it in many ways, but I really like to know how to split a mesh with its edges. Thanks! Edit: This guy is not Pikachu, he is Bulbasaur.
