Using Advanced Modeling Techniques
Creating complex geometry isn't always as easy as opening the Family Editor and starting to model the shape that you think you're trying to create. Sometimes you need to model one form in order to create another form. And sometimes you need to model a complex, parameterized form in order to parameterize the actual shape that you're trying to create. So that you understand these advanced techniques, we'll first cover the available geometry types that can be created in Revit.
There are five discrete geometry types in the Family Editor: extrusions, blends, revolves, sweeps, and swept blends. Both solid and void forms can be modeled from these shapes.
Which one you select is important, but our advice is to use ...
