HI Paul,

To build your floor plan you can use the interal stencils from the Shapes dialog box (left-hand side of the screen when you open a file) and click on "More Shapes" to access the stencils. Then click on "Maps and Floor Plans" / "Building Plan" the scroll all the way down and you will find the Walls, Doors, Windows, etc stencils to build the floor plan. Of course, there are other stencils you may find useful.

I, again, tried to upload a file (.vsd extension) but, again, got the "invalid File" response. Wish I could help further in that regard.

Hope this helps...
