I have many large spreadsheets outlining the dimensional details of very simple parts. The parts are classified as Styles A through G, with a maximum of 6 dimensions per part. I would like to find a way to model these parts automatically without manually creating a sketch for each one.

I would also like them to be in the same part file as separate bodies.

Is there any easy way to do this?  I've heard design tables mentioned, but that tool doesn't seem to lend itself well to this.  Of course, I may not be using it correctly!
