OK so I'm on the road to mastering this software and I've just started my trip. I'm working with a geometry for practice that has three separate parts in it. I want to block mesh those parts but they are not connected at all so I need three different blocks. How can I create three separate blocks that do not depend on each other? When I do make more than two blocks the software asks me if I would like to merge or replace the current block. If I replace then the work I've done is gone but if I merge then it changes the parameters in the first block. How do I use multiple blocks?
