Generic Model Outline Families

Complex building forms frequently require different individual forms joined to or cut from one another to create the final building shape. Just as in any other family, the more complex it gets, the more difficult it is to properly constrain. Each form element requires its own set of constraints and parameters and sometimes requires additional constraints on the original form element to keep it stationary when the second element is flexed. Multiply this by 10 form elements, and you can imagine how difficult it could be to keep control of the family.

Fortunately, there are alternatives to this highly complex environment. Nesting families into other families simplifies what would otherwise be a difficult family to ...
