At menu: "Modify -> Edit strings -> Create a Boundary around a model" You can even Triming by length… Question is: "How to put this in MOSS code, and code trimming for short in number, it seems only a draw option. I want to use it as Crosssection cut to copy section set in Boundary, and as Boundary or PBRK in Triangle creation. Thanks a lot Li
