I am using version 16.1. I have been on it for weeks plus am learning the software along if anybody in coventry is willing to teach then ill be glad to learn even at a fee.
Thank you very much @Pankaj. but am using the workbench platform and my major problem is that on the ACP Prepost screen, my model does not rotate i.e. i cant rotate the 3d format around to click in the hollow section.
