Default Torus Wanted

Does anyone have a Torus that I can add to the AC3D shapes. Thanks.

Add a circle in front view, and a second in top view.

In Object mode, select the small circle then shift select the large circle (order matters!) Then choose Object->Extrude along path. Change to Vertex mode and delete the half that isn't closed...

Finally, choose Object -> Mirror -> X+ (or as appropriate), then vertex mode, Vertex->Snap together by distance and Vertex->Weld.

This final image shows a couple of levels of subdivision as well. I make these fresh each time because its much easier to edit the individual pieces before the extrude since I rarely want a perfect torus shape.

That's a nice illustrated tutorial for extruding along a line but for a torus, it's probably faster to create a circle and use Object->Revolve. There's a small example in the AC3D manual (available from the help menu).

That's probably a better method if an exact torus is needed, but I often want to model toroidal-ish things like this pear-shaped carabiner-ish object.

I must be totally dense in reading the manual. I create the circle in the front window. Select Object Revolve, set the resolve panel as shown in the manual, click revolve and I get a sphere, not a Torus. Totally newb. Any thoughts?

Haven't read the manual but... Revolve works around the origin, if you're creating your circle at 0,0,0 and revolving it, you will get a sphere.

Thank you for the quick response! That's what it was, I was trying to do this on the origin. Great to know that revolve works around it.
