Hi guys, first time poster here.

I'm trying to find a way to slice open a 3d file composed of multiple parts with some embedded inside a main piece. Basically it's a prostate with 2 lesions and the urethra running through it. I'd like to be able to split the main section of the prostate in a curve so that I can put the lesions and urethra inside of it (printed separately) and glue the whole thing together if that makes sense. Does anyone know how to do something like that?
