Database application based on AutoCAD drawing ???

I want to create an application that displays a drawing in one pane
and some database information in another (side pane).
The drawing should have on it some images that represent records in a
database and are "hotspots".
When a image is mouse-clicked the information in the side pane is
changed to show information relivant to that database record (or
image).

I have no idea where to start, I need some expert guidance.

Is this possible using something like AutoCAD or should I be looking
at writing something from scratch using VB.Net (for example)??


Any help would be greatly appreciated

Thanks in adavnce,  SKIP
