We would like to be able to add a mesh to the SolidWorks feature tree (this is for a part document), and have it visible in the view, so that the user can (1) have it saved in the part document, and (2) use it as a visual reference while modeling. The mesh would be created from data already held in memory by our C# SolidWorks plugin. What is the most appropriate and/or future-proof way of doing this, solely through the API? (We don't want the user to have to save/reload an STL file, for example.) Thanks!
