Nope, Analysis Situs is a single-part thing. For assemblies, we are working on another software that uses Analysis Situs as an SDK (to take advantage of its XDE bindings), but it's far from completion.Hi, does this software have a function to select individual parts of an assembly directly like selecting vertices, egdes, faces, etc. I used the “Explore...” function you mentioned, and I feel like it's redrawing a selected part instead of directly selecting a part that already exists in the assembly, which would take up a lot more memory if the assembly is very large, right?
