as long as I'm wasting space

"I want Visio to create the drawing via database, it should come out as rectangular blocks. Hard to describe but for example, say that you have a car diagram and you want to highlight/indicate which parts can tolerate which temperature settings"
The good news is this is relatively simple. There are a couple of examples already floating around in here on reading Excel sheets and dropping boxes for different reasons (flowchart demo's are the most common). All you need is to read the sheet that has the name and pinx/piny locations.
