I can not seem to find the command to make a 3d text layer with depth (extrude). I can manipulate the layer in 3d, but the layer has not depth. I have found something in the EFFECTS > 3D Channel that has variaables for the "Z depth". Changing the Z dimension does not seem to affect the depth of the text.
I am using AE 6.5 and am well versed in other 3d programs such as 3D Max.
