Creating a Composite Surface from an Imported Mesh.
I'm currently investigating Onshape for our company, to replace Autodesk Inventor. Referring to a discussion here https://forum.onshape.com/discussion/5248/recognize-stl-as-a-solid-for-use-of-full-suite-of-part-studio-tools#latest I have a need to be able to convert an imported mesh into a composite surface, mainly so that I can use the Intersection tool in a sketch to derive section curves from the surface. The only way I have found to do this so far is to use the three vertices from one element of the mesh to define a plane, do a sketch on the plane of a triangle defined by the three vertices and use that to create a small surface. You would need to do that for every element on the surface to convert the whole mesh. Is this something that could be done using FeatureScript? Maybe the script could have an option to select an area of the mesh, rather than the whole mesh, to reduce computation time?
