Thanks for the comments. Much appreciated!
WillMSP, if I had a Xerxes, I’d be worried about mucking it up too. That’s supposed to be a very nice table.
Barb, one advantage of using CAD is that it makes it so much easier to explore alternatives. I usually go through many design iterations before committing to anything. Of course, the learning curve can be steep. In my case, I used to work for Bentley Systems, who produces a CAD system called MicroStation, so modeling things is second nature. When I retired and no longer had access, it felt like I’d lost an arm. Learning SketchUp was not that bad, though. It was just very different.
