If you have a block with one cylindrical hole and a fillet on one edge there are some inconsistencies within using modeling. 1. select the fillet, RMB, change radius, enter the new radius, ok -> radius was changed 2. select the hole, RMB, change radius, enter the new radius, ok -> nothing happens 3. If the fillet has a radius of 10, click on an neighbour edge, create a new fillet with 10 -> error Other inconsistent usage: You have an assembly with 5 parts. Copy part - select three parts - new position - ok Share part - select three parts -> not possible
