How to add U size to custom stencil?

[Steven]

I built a custom stencil for a piece of rack-mounted equipment but I can't
get it to display the U size. I tried doing it through the "custom
properties" settings but it still won't work.

Any help would be appreciated.

Are you trying to emulate the behaviour of the Rack Mounted Equipment in
Visio 2003 Pro?
If so, do you have the formula
=SETATREF(Prop.UCount,SETATREFEVAL(SETATREFEXPR(0.2667
m)/User.OneUHeight),TRUE)+ROUND(Prop.UCount,0)*User.OneUHeight

in the Height cell? (and have all the referenced cells)
