yes i use the model tool for every project. i create a model layer, use the tool to make one model with all the layers i want, then save different views for different uses, excluding and including classes and layers that i want (a render view will have landscape and gingerbread layers on while a model for taking 3-d sections will only have a few on) i always use the model for sections, elevations, renders or whatever. for elevations i copy model to lines, put it on a model elevation layer and begin to draw polygons to cover shapes and use compose to make polys. i will go back to the model and choose 3-d objects and convert copy to polys so i can add it on top of the elevation drawings. (helpful for railings and stairs and stuff that creates a lot of lines when converting to line). the order of objects is important, i rarely trim or cut, just cover. i have found that adding more to the enormous amout of lines is faster than trying to take away-
