Setting length of walls to be fixed

[Hameed]

I'm drawing an architectural diagram in Visio 2007 and am drawing my basement
to scale.

One problem I have is that when I drag a wall onto the grid and set it's
length, as soon as I join another wall to the first on it's corner, the
length of the wall changes and I cannot change it back.

How do I lock in the length of a wall so that it does not change when I drag
it and join it to another wall?

Presumably you are measuring the inside distances...

Before "freezing" the wall length and taking away some of Visio
functionality, perhaps this will help understand what is happening. In a
nutshell, Visio adjusts the length of a wall to compensate for the adjoining
wall thickness...

If you notice when you place a wall, the connection points are on one side
of the wall only. This is critical to how you put the walls together. So,
if you have interior measurements, then, every wall must be placed such that
this edge of the wall is the interior surface. When two walls are joined, it
will be the exterior length that grows by the width of the added wall. If
you place the edge with connectors on the exterior side, and join walls, then
the interior length will shrink by the wall thickness. Actually, it's pretty
handy. The critical element is being consistent, interior to interior or
exterior to exterior. Yes, you end up doing a lot of flipping / rotating
before you join the walls together.

The one place this becomes a problem will be "T" intersections. Invariably,
there will be an interior / exterior mixture. I haven't tried overlaying two
walls on top of each other, say, the vertical leg of the "T", with the
connectors on opposing edges. That might help maintain some sanity.

Let me know if this helps.
