DXF/DWG Import - Document Settings

While using the DXF/DWG Import wizard to create a new b-sizeformat, I was unable to select the B-size paper as it wasgrayed-out. I suspect it is due to the settings described in theSolidWorks help file below. What is the default path for thedocument import template?

Output file properties
Paper size. Sets the drawing sheet size. Select User Defined tospecify the Width and Height.

Document template. Sets a document template for the importedentities. If Paper size, Width, and Height are specified in thesheet format of the template, these settings update accordingly.This template information is saved in the registry for DXF files,and used in future DXF file imports unless you change the template.
