I'm trying to create a series of arches based on a single molding profile. I've created each arch as a curve and the plan was to then take the profile (a single face at the moment) and extrude it along the curve to create the arch I want. However, something I can't even explain is happening and the extrusion is not conforming to the curve. I've also tried extruding first and then attaching a curve modifier and get the same result.
If it will help, you can download my blender file here. http://www.mediafire.com/?27kos3cwfkf2c
Let me know what I've done wrong and thanks in advance!
