Right, sorry if the pictures are a bit small, but look at the group on the right where I'm previewing a 3D effect.


Notice how there are three turquoise stripes running along it. (You can look at the 2D version)

Basically, I change the extrude depth from 50pt to 30pt and for no reason at all, the middle turquoise shape vanishes!!

Is this a bug or what?

It's a bug in the 3D effect display. You can try changing the perspective by 1 degree or adjust some rotation by a minute amount.

Basically, you just have to play with minor adjustments until everything appears correctly.

Illustrator's 3D effect is "adequate" at best. It's never been wonderful.

Thanks very much for clarifying that. Appalling to be honest, considering this is version six and costs £30 a month. Slight deviation, but do you know of any dedicated 3D vector programs, then? – Starkers Jul 23 '13 at 11:08
Actually vector 3D is a tough thing to find. Swift.3D and Google SketchUp are probably the two best I've found. It is a shame Adobe doesn't address 3D in vector form a la Dimensions (from the 90s). – Scott Jul 23 '13 at 11:19
