Yes, I know that Illustrator already has that ( I use illustrator as well), but thought some might be interested in the release of Xara Xtreme 4 which includes the extrude, bevel and light tools that were formerly in their Xara3D software.
It is incorporated now and it's quite handy to do some quick extrusions and adjust all the colors, lights, fills and other powerful tools in Xara Xtreme.
No, I don't work for them, just like their Vector Program.
There is also a pro version of the software, more suited for those who publish.
Some quick examples of the new extrude tool. Yes, the extrude object can be rotated in any direction as shown in the image below.
