Create and explore conceptual mass families with this workflow. 
In most cases conceptual masses go through several design iterations before meeting the desired project requirements. 
- Open a new family using a Mass or Generic Model Adaptive template. 
- Sketch the points, lines, and 2D shapes that will comprise the 3D form. 
- Extrude the 2D geometry into a form. 
- (Optional) Divide form surfaces to prepare the form for components 
- (Optional) Apply parametric components. 
- Load the conceptual mass into a project.
