I am trying to create a nightstand leg that tapers from a 2x2 square to a circle with a 1” radius. In the attached model I placed a leg that is square, with a rectangle at 5” from the bottom, where I want the taper to start. In front of that on the left is a cylinder with a 1” radius, and next to it is the same cylinder with a 2x2 square on top. I then drew guidelines from the center of the circle to each point of the circle (only one shown here, too messy to show them all. I then connected each of the points from the square to the corresponding point on the circle at the bottom of the cylinder, those can be seen in the part that looks like a wire frame. Needless to say, this did not form a solid. Now I am stumped as to how to do this and will appreciate any help the forum members can provide regarding how to accomplish this.

Something like this?

Manually you could stictch between the square and the circle using the Line tool. Faster would be to use the Curviloft extension to automatically create the surface around the leg.

Curviloft is available from Sketchucation.

Side note about your model. I would suggest you leave the model axes visible and keep your model close to the origin. As it is, your model is located below the ground plane and quite a distance from the origin.

Also, do your modeling with the camera set to Perspective. Save Parallel Pojection for scenes for dimensioning.

Maybe these post can help?

You would probably get a nicer leg shape if you rounded the corners of the square face.

I was playing around with your model. Rounding the corners of the leg does make the transition nicer. I also slightly reduced the diameter of the foot.

Instead of Curviloft for this version I used Extrude Edges by Rails in TIG’s Extrusion Tools. Also available from Sketchucation.

I had a bit of a play. I hope you don’t mind. No idea what you really want the table to look like.

By the way, there’s no need for both horizontal and vertical versions of textures. One will do.

And, for the curious, see this SU file for more ideas. Similar to Dave’s model.

Dave - as always, thanks for the help. FWIW, the leg was copied from a model of a bedroom and is placed properly with respect to the axes when the whole model is viewed. I just did a copy/paste to a new file to post to the forum. Thanks again, I know I can always count on quick and accurate help from you and others on the forum.

Thanks for the reply and the tutorial
