Thanks for the swift response Andy.

Looking at the information at the top of the control panel certainly helps, - I had not been taking note of that.

Probably I was trying to run before walking, but my question was a result of trying to understand the process of constructing a complex model - such as the f16 in the sample library. I was getting nowhere trying to isloate the consituent Objects by boundary boxing likely candidates. Since reading your post I have learned the value of the Tools > Hierarchy view - which does the isolating for me.

You are also right about the vetex selection. I was only dragging around one visible vertex, but that catches the one behind it. All works as it should if I simply click on that same vertex.

This is turning out to be more interesting/fun than I thought it would.
