Dimensioning standards

[Galingula]

I've always dimensioned architectural plans this way, and it says so in our general notes....

Interior stud walls are dimensioned to the center line. Exterior walls are dimensioned to the outside fiace of the plate.

Is this a standard? Or am I off base?

That is how I was taught, but then again at the firm I work at now the dimension inside face of wall for interior.

Interior: centerline-to-centerline.

Exterior: out-to-out.

Yep. Works for me.

Its the way I was taught how to dimension....and the architectural books seem to agree. The only interior walls you dimension face-to-face are masonry walls.

Some contractors prefer interior walls be dimensioned to their face and that might be why they do it that way at your company.

In our office we do face of finish to face of finish. However we are currently changing over to center of stud to center of stud. The only finished face dims we will be showing is the overall layout.

At one place I worked, they dimensioned to both sides of the interior stud. Where I work now, they dimension to one side of stud on the interior, and on the exterior they sometimes dim the total wall thickness (frame + masonry) or just to the very outside face of the wall (masonry).

I personally don't like dim to center of stud because it's easier for contractor in field to layout interior stud placement if you dim to one side of stud. I also don't like dim to finish for the same reason and also because I have seen an arch do it that way before and then he changed him mind 5x on the size and type of finish, therefore created a lot of unnecesary work.

I was told that dimensioning to the center accommodates dimensional variances in the wood. Same goes for steel beams and columns. Dimension to the centerline. The manufacturers are given "nominal" dimensions to work with. A little more (or less) one way or the other is acceptable. Did I state that correctly? Come on Stykman, save me here...I'm drowning.
