The surface profile basically describes how much it can vary from that. Surface profile can be equal bilateral, unequal bilateral or unilatera. Take a look at ASME Y14.5M-1994 section 6.5 if you work to American drawing standards. http://www.draftingzone.com/shoppingzone/dmpgt.pdfhttp://www.tec-ease.com/gdt-tips.htm http://books.google.com/books?id=ig...&oi=book_result&resnum=1&ct=result#PPA497,M13 This is a pretty basic level question, you really need to do some reading and preferably get some training if possible.
