multiple cps

[bravo2080]

I am having trouble with multiple control points. I'm using 2005. I create a sphere by making a 2 point line, latheing it (lathing?) then I delete the bottom cps. I then highlight all the cps and rotate by typing in 90 degrees.

The result is a perfect sphere with the exception that multiple cps are created at each point.

When I pull one cp away, there is 1 or 2 more where I pulled the first one away.

Can anyone help with this?

Thanks

looks almost as if you extruded a section without an offset

Thanks for the quick response. How is that happening? I lathed a typical vase and am not getting the same result as with a sphere. It just seems to be happening when I'm trying to create a sphere.

thanks

hard to tell but somehow you doubled up it happens.... try again and stop at each step and check

Ok, I'll do that. Thanks again.

The problem is you're lathing a circle spline. You only need a semi-circle in the positive x axis.

I didn't know I couldn't do that. I tried with a half circle with success. Thanks for your help.
