Is it possible to run a pyhton script on an unopened mxd? I was thinking of a havinga "Master" map that users could digitize polygons in and then run a tool that applied their new polygon (as a definition query) to three other mxds. I have scripts that run individually (1 per map) and was hoping to combine them into a single tool. Am I way off base? Is it simply a matter of referencing the three mxds? Thanks.
