No, there is no native thickness in AE. You will have to use effects like Shatter or Card Dance to fake it, but there are quite some limitations. also there are several scripts and tutorials on fake "text extrusions" using stacks of layers.
I cant believe they havent put something like that in AE with everything else it can do! Oh Well! Well I found some tutorials on the shatter effect that seems to work but the problem Im having with it is when I extrude it to give it thickness, then rotate it a little to see its thickness, It doesnt seem to have "filling" in between. Its like 2 paper thin layers over each other but with some walls connecting (attached a pic to show what I mean). I generally do minor 3D effects like this with Illustrator, but with my desire to learn AE, I want to try to keep all the layout within AE as much as I can

Yeah, and I'm still waiting for my microwave oven to do my house cleaning. Why haven't they added this feature? It's so obvious! Forgive the sarcasm, but none of that should bhe assumed to be simple, easily apparent or even logical. Software development is hugely insane. And if you are an AI user, you should have a pretty thick skin in terms of missing, defunct or only half-working features. No different with AE...
