Hi All-

I'm trying to create a 3D dome in AE CS6 using the ray-trace features. I've managed to create a 3D sphere, but can't seem to cut it in half. Does anyone have any ideas?

If it helps, I'm trying to re-create this landmark in 3D space...

I've managed to make the pillars and the pedestal, but can't make the top!

Any help would be greatly appreciated...

Best,

Ae CS6 lacks modeling tools. If you can't extrude/bevel it, you can't make it in Ae. (You can only make full spheres via a clever bevel hack.)

Tom's advice to use a plugin like Element is probably best.

You can make a full sphere pretty easily by typing a . and then setting the bevel style to convex, bevel depth to 100, hole bevel depth to 0 and extrusion depth to 10. Just can't really mess with the shape afterwards in Raytrace 3d.

Thanks though.

That's the clever hack I was referring to.

In a proper 3D package, you have primitives, which are elemental pieces of geometry that you can easily generate: spheres, cubes, pyramids, planes, etc. Ae CS6 doesn't have these, so to get a primitive sphere, you have to bevel the heck out of a circle as you describe. As you note, once you do this, you can't really do anything else to it (like modify the polygons or cut it with a Boolean operator and a box).
