Is there a way to stop walls in Visio automatically snapping so they're 90deg? I have two walls which meet at about 85deg, but Visio thinks it knows best.
I'm looking at Visio 2007, so this might be different in other versions.
You can specify the measurement manually: View > Size & Position Window. select the object. Type in the angle you want.
To turn on/off snapping, show the snap toolbar: View > Toolbars > Snap & Glue
