I am building a parts list for the maintenance of a machine.
I have all the AutoCAD drawings of the machine components.
What I would like to do is when the user selects a component, an image of that component appears and the user clicks on a part (let's say a specific bolt or nut) and thus the part information appears.

In other words I would like to make a mapped image (as in HTML) and refer to a record in a table.

Does anybody have any idea on how to do this?

Thanks.
