Modelsheets

Hey guys, I'm currently in the process of making modelsheets, but I remember there was talk last class about having the trees modeled in sections that are attached together. Does this fit the description? And also, how should I go about creating the before and after versions of the trees? Should I have separate model sheets for those for separate models? Or some houw make a trunk with branches which the "lush" sections can attach to?
