Small Stellated Dodecahedron - Shout At The Devil!

I woke up to an email from Yoda at Autodesk challenging me and another blogger to make one of these in Revit:

as featured in some MAKEZINE Blog....

Being a dutiful Padawan, I jumped right in....First stop, Wikipedia, to find out what exactly a Small Stellated Dodecahedron is.  They said its one of these:

Aha!  Its a bunch of stars all wrapped around each other....that should be easy.  First thing to do is make a Pentagram...a tilted Pentagram....so come now children of the beast and take a walk with me....


Point 1 is the origin of the whole affair.
Point 2 is a Z offset from Point 1
Point 3 is a Y offset from Point 1
Using Trigonometry, these points establish both the tilt and height of the star.
Points 4 & 5 are offset from Point 3 and will establish the width at the base of the star.
Point 6 is a backward offset from the angled reference line in order to create the circle.

Now you can see the circle...and the devil is coming home to roost!
Setting out the circle is important because it was the only way I could figure out how to locate Points 7 & 8 accurately.
Point 9 is the host for the circle and it located at the midpoint of a reference line between Points 2 & 6.

I created an adaptive component with 10 points which would establish the surfaces on the finished form.

I nested my tilted pentagram rig into a new conceptual mass family and started stitching in the adaptive component.  This is only one half of the final form.  To complete the deal, I nested this one inside yet another family and then flipped it upside down like this:

add in some bubbles and bones...


and Booyah, I believe I'm the Devil's Child....
