"I imagine it was done in Illustrator. I know you can copy and paste the logo, downsize it, place it behind the original, do a blend and combine the blended steps. However, doing this does not show the "planes" of the letter. The only way I can think that you did it was to sit and painstakingly draw each line with the pen tool. Am I right/wrong? Any help would be appreciated."
Those logos were done using KPT Vector Effects, which is a great set of plug-ins for Illustrator. There's one called "3D Transform" that lets you control the angle, perspective, depth, bevel size, etc. KPT plug-ins are great, and this is no exception.
The filter is geared more towards metallic-looking realistic stuff, so to get the "hard line" comic-book look, set the "Complexity" and "Metallic" settings as low as they'll go, ignore the color settings, and after you apply the filter, set the whole object to Black line/White fill with round corners.
Note: Vector Effects has not been updated by Corel for OSX or recent versions of Windows. However, Illustrator CS2 now has a 3D effect filter built-in, which appears to do basically the same tasks, though we've yet to check it out.
