How do I configure ProMax to use A4 size paper?
In Options.xml, change the //ProMax/ReportOptions/Paper node text from “A” (letter) to “A4” (without quotes). You also will likely want to change the default Visio template from a letter size based template to an A4 size based template. This is accomplished by changing the //ProMax/ProjectTemplate node text to Project-A4.vst.
