Collection is compatible with Visio versions 2003 to 2013.  Stencil folder is My Documents\My Shapes\   (Path names vary for non-US English versions)
These stencils work best for any scale templates from 1:2 to 1:30 but NOT Visio's "Blank Page" which is 1 to 1 (no-scale)
Visio's "Blank page" causes much frustration.  Use our templates instead, they have all the right settings to make Visio much easier.
