OOPS, I did not say anything about it being a SketchUp drawing, sorry!
Pete,
Do you still have Google SketchUp installed (do I remember you recently replaced your computer with no small pain)? This is the link to SketchUp, the current version is 7 (the posted file is still ver 6, but StetchUp converts it with just a small complaint).

Chuck, it is not a plug-in, but a whole little 3D drawing package from Google. You can even upload drawings (like of your house?) to Google Earth. There is a free version (I use that one) and a pay for version with additional stuff.
It is geared toward encouraging 3D drawings, and compared to some other drafting packages I have used the 3D stuff is tons easier. It does take some work to learn how it wants to be used, but if you need some 3D stuff, it can be really nice.
But just to look at the drawing it is not so hard to do.
Have fun,
Charles
