I am working on a project to make several drawings to be handed out to dealers in my field of work.  Thus being said there are several different sizes being made.  Mainly the length of the product is being changed in 2 feet increments.  I am using design tables to increase the length of the from one drawing to the next.  This allows me to just do a save as to create a new drawing.   The problem I am running into is changing dimensions or adding notes once I have completed several of the drawings.  There are about six pages per set of drawings and 300-400 drawings total.  So you can see how this would take a while to go through to add a snap point for a dimension to cling to.

So the question is how to change several drawings at once by changing snap points or adding notes to one drawing which will drive the rest.

Any help would be greatly appreciated!
