I work routinely with some fairly large assemblies.  In the process a lot of parts are added and/or deleted from the assembly file and it makes for quite a bit of work maintaining the drawings.

One issue that I am dealing with is that while parts may be deleted, the explode steps for the drawing views are not.  I've dealt with explodes with as many as 150 steps, but many turn out to be empty.  I've worked the issue so far by manually walking through each of the explode steps and deleting the empty ones.  But others in my office are not so skilled or patient.

Is there a command I am missing that will help me get this job done or (more likely) has anyone ever heard of a macro that will do the job?
