Extrude object along curve not working 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.

Let me know what I've done wrong and thanks in advance!
Well I'm not sure what technique you are using to "extrude along a curve".  The array modifier is one way to do it as moonboots mentions.  Another one, which I used to create the image below, is to convert your profile mesh to a curve, then use it as the "Bevel Object" of your arch form curve.  You can then convert the resulting curve to a mesh (as I've done with a duplicate in the screenshot).  You will need to be sure to apply location, rotation, and scale to your objects, INCLUDING the arch curve object, to get this to work right, and even after that you may need to rotate the profile (and apply the rotation) so that the right bits are pointing in the right direction.
