Auto-number drawing based on model
We have automated numbering for our models. For our drawings, we use this convention: drawing number = model number + "-DRW".
The downside of this is that the engineer has to manually number the drawing. Sometimes they number it incorrectly, and sometimes, duplicate drawings are created. I have the fun job of finding those issues and cleaning them up.
Is there a way to get drawings to auto-number based on the model?
One additional caveat: sometimes our engineers like to include multiple models in a drawing.
I was thinking of trying to create a workflow that ran on check-in to handle this, and assign a task to the user if the primary model number couldn't be determined. I'm hesitant because then I'd have to have that workflow run on every CAD file checked into the system.
Any other ideas of how to accomplish it?
