Just in the planning stages of finishing my basement.
When I actually start to locate my 1st wall, what's the correct method to get it/them squared?
Thought I remember someone talking about a 2,3,4 rule?
Is it easier to start with an inside corner or an outside corner first.
Do I take measurements / plumb from an overhead I-beam towards the first wall I plan to work on?
Just trying to plan ahead.
Thanks Dave
