Hi Jack,
There's no Visio equivalent to the Normal.dot that Word users know and love.
However, you can get close.
When you start a new drawing, select NO shapes, then choose the line
rounding that you love - most easily with the Corner Rounding button on the
Format Shape toolbar.
Anything you draw after that will take this rounding. But shapes that you
drop on the page from stencils won't - they've been pre-formatted.
Your second option is to build a template (.vst) file that you use instead
of Blank Drawing. You can add styles to this drawing, set the rounding, open
the stencils that you use, add background pages, company logos, etc. to this
drawing so that your page is as-ready-to-go as possible. Then you can base
all your new drawings on this template.
Note, to get your template to show up in the File > New > Choose Drawing
Type screen, visit the template path settings located under: Tools > Options
Advanced > File paths button.

Hope this helps,
