Hollow Connector Line

[SWL Developer]

How can I make a connector that looks like 2 parallel lines (or a hollow line)?

I want the features of a connector (stay connected to blocks, re-route at 90
degree angles around other shapes), but I want the line to appear as 2
parallel lines (or a hollow line).

So far all I can think of is make a thick black connector line and then draw
another thinner white one on top. But when I do this, I have to create 2
separate entities, and I have to move 2 separate entities if I want to make
changes.

Your method would work fine if you referenced the corresponding ShapeSheet
cell in one of your two connectors from each geometry cell of the other.
The more obvious solution, however, is to create a custom line pattern.
Look up custom patterns in Visio help. When you go to create the custom
pattern shape, just draw two horizontal lines on opposite ends of the
pattern shape's drawing page.
