That does make sense. I suppose it’s similar to the way exec’s were not meant to be converted back to source. It was mostly a question out of curiosity. Though planes/cubes and the likes do convert currently, the tubes and spheres have posed a small hurdle to get over. It’s easy to remake them roughly to what they were, but yes indeed, being done in the actual conversion would certainly be so much easier in the long run. It’ll be really nice to have this in the next version!
