To show the application of solidworks in (lateral) surface development to my students, I would like to develop lateral surface of full solid or truncated solids in solidworks. i am facing problem in case of full solid like hexagonal pyramid. I have done surface development of truncated pentagonal pyramid (see attachment-Pentagonal pyramid) is it right? Please help me to solve problem in case of (lateral) surface development of full solids (See attachment- Hexagonal Pyramid) and also for cylinder and cone. A reference image is also attached.
