Thanks Eduardo for asking for non-manifold topology. It was a very unique and strong feature of DS Studio and I think Dynamo would benefit from it. Anyone reading this, please post a reply here if you think we should have that feature back in Dynamo. One of the features that I also needed in conjunction with non-manifold is to allow surface, and lines to have ‘children’ (sub-surfaces and sub-lines). This becomes extremely useful for glazing ratios in thermal simulation and in determining linear thermal bridging using different materials along the edge.
I don’t think it matters if not many people know about it. In fact, just a few years back, not many knew about many of the concepts in DS and Dynamo. But once they see the features, they will use them.
For now, I am using non-manifold in 3DS Max to conduct EnergyPlus Simulations! (See below) Would love to port my work back to Dynamo.
