Is there a way to control position of thick border lines?

[Jennifer]

If I give a shape, such as a circle or rectangle, a thick line (Format | Line | Weight),  the line is centered on the edge of the shape. This means that the apparent size of the shape is increased by one half the thickness of the line.

Is there any way to tell Visio to align the outside edge of the line with the outside edge of the shape so that the extra width is all inside the shape and the outside dimensions are preserved?

this would take 2 shapes....original and copy that is slightly bigger....centered on each other ...copy in the back...group them.

The difference between original an copy is that the width/height of copy = width/height of original + desired line weight.
(on the original you have to put the guard statement on its line weight....changes in lineweight would be applied to the group and copy only)

Both would need the groups PINX and PINY to stay lined up when you move them around

All this is done via shapesheet for the group, original and copy

Yikes!!! 

And if I change the line thickness, I'd have to redo it?

I was hoping for a way that would just allow me to tell Visio to put the extra width inside the shape.

Thanks.

if you set it up right....no you dont have to redo each time you change line thickness
(when you set up, you may have to play with the units since lines are weighted in pts and dimensions in mm or inches....maybe copy line weight to a user cell and covert to mm).

Look at the line connectors from June the Seconds ...they do what you want

June's stuff can also be found by googling "isometric visio"
