Problems extruding a circle along circular path I'm trying to extrude a circle along a circular path, ending up with a torus.

First, I added a Bezier circle centered at 0,0,0 and made it 10x10 in width and height (to form the path), then I added another circle, also at 0,0,0, and made it 2x2 in size.

When I select the smaller circle as the Bevel Object of the larger circle, the resulting shape resembles a swollen torus with a slight depression in the centre (where the hole would be) and becomes 20x20, larger than I expect.

I've tried positioning the smaller circle in different places, and at different angles before setting it as the Bevel Object, with similar results.

Any ideas what I'm doing wrong?

Here's an image of the two curves, then the end result:





Update

Just in case it helps anyone else, I think my problem occurred because I was scaling the larger circle (the path for the extrusion) via the Transform panel in Object mode rather than Edit mode.

Instead, if you add the (larger) circle, change to Edit mode and scale it to the correct size, and then change back to Object mode and set the Bevel Object, everything works perfectly.

Not sure if it's related, but a response on another site implies that you could also scale in Object mode, then Apply -> Scale, though this didn't work for me.
gandalf3's answer is the most likely answer and solution to the problem. Another thing you could try is shrinking the bevelled object with AltS. However, I see no advantages in obtaining a torus from curves that way. Why not just add a Curve > Circle and tweak the settings. To fatten, increase the depth and to get it smoother/rounder, increase the resoulution. Much easier to tweak and less work.
