I have found several threads with discussions about having invalid meshes due to duplicate vertices. In the old .NET sdk this was not the case. Duplicate vertices were allowed. My plugin creates meshes which I import and export as regular grids, that is I write rows of vertices and the number of rows and columns. This format is required for some of our simulations. The simulations handle duplicate vertices fine and this is how we deal with surfaces that come to a point. The restriction on duplicate vertices in Rhino6/RhinoCommon leaves me scratching my head about how to deal with this. No clean solutions come to mind.
This may blow up my plugin for RhinoCommon all together, since these type a if surfaces show up frequently.
Does anyone have any potential solutions for this? Removing duplicate vertices destroys the ordering of the vertices, which is critical.
