Pump(k)in' Up!

Halloween provided us inspiration to put our Revit family skills to work. Find the process of creating a fully parametric pumpkin using a single point adaptive component and a divided path. This tutorial was presented at the November 14 Redwood Empire Revit User Group.
You can create a parametric pumpkin by nesting a repetitive single point adaptive component into a tiny circular divided path.

It’s always been in the back of my mind every Halloween day. How to create a fully parametric pumpkin? The concept was very simple. Create a single ‘wedge’ component and array it. The challenge was that you can’t create polar arrays as we know it in the Mass environment because the command ‘Array’ simply does not exist here. The other challenge is with partial elliptical profiles. Unlike Arcs and Splines, partial ellipses are rigid to control intuitively because the start and end ‘nodes’ will not reshape the ellipse size after placement. So I had to drive the ellipse size via parameters. 
Dragging the ends of a partial ellipse will not change the ellipse size.

I created a polar arrays of components using a divided path on a circle with visible nodes, and nesting a single point adaptive components as a repetitive component, and viola!
