If the modeling room in C5 won't be improved then I will consider not continuing to work with Carrara. I have invested several versions and asked them to improve it but they did not. Beazer curve function and symmetrical pointers (mirror on sides) and improved tessellate tool is probably what all pro modeler needs. I do not want too many complicated tools in the toolbar like in Hexagon. What I suggested is simple and complete necessity tools to make a model, it is perfect for Carrara.
