I am doing a little fishing in the dark.

What i want to accomplish is creating a checker that will determine if a drawing is fully constrained and this is how i plan to do it.

1. Any given dimension is connected to a face, edge, or hole center. Is there a way to make a connection from the edge the drawing to the edge or face on the model?

2. If i can do that and create a list of beginning and end faced and edges. how would i take this list and compare it to all existing faces to see if there are and not      dimensioned?

3. figuring out faces that are though other dimensions

I know this will take a lot of work and programming and any advise will be vary helpful.
