In my senior year in college, I had a project to work with a moulding company to create a web site for them. They needed a way to show their products online.
The first thing I noticed was that all their images were profiles (simple outlines) of the shape of each piece of moulding. That made it extremely difficult for a customer to see what it would actually look like.
So I used the extrusion feature in Blender 3D. I traced the outlines of the profiles in Blender with the image as a background. Then set the camera off at an angle, extruded my lines, and added a wood texture. Now you could visualize what the moulding actually looked like.
Below are some of the profile images and their extruded versions:
