Hi !
So, I wanted to test and run this sample code:
I cloned the repo, and built the specific solution for “SampleExportMeshPlugin”. I also successfully got a .rhp file and have installed it. The problem is, it doesn’t have any commands which I can type and run.
This particular plug-in works through the Save As… dialog, where you select the .mesh file type. When you give a valid file name and confirm Rhino will call the WriteFile() function for this plug-in.
