Amazing I'm not even going to try and figure out how you did this

I have no idea how you managed to do that!
10/10!

Downright astounding, and well deserving of 10/10.

Did you use a loop to shift the coords of the vertices over to make the bolt 'turn'?

i see whats going on, but not how its done

I delete the screw and redraw it for each angular increment. I use a function I wrote called Scene.my.drawScrew(D, P, L, Rot); where D = screw diameter, P = screw pitch, L = screw length, and Rot = screw rotation. You can create a screw from the console by entering this function with some values (for example, "Scene.my.drawScrew(0.375, 0.0625, 1.00, 1.57)"). You can see the function code by entering "Scene.my.drawScrew".
