Hello.  Following up on my question from yesterday (which I marked "correct answer" since my original question was answered), I'm now trying the revolved cut on my railing spindle drawing as suggested instead of doing in 3 parts.  I'm getting the "zero thickness geometry" error even though I thought I was going about the steps the right way.  Suggestions on what I'm doing wrong?  I'm posting the .sldprt as well as a screenshot.  Thanks again.
