We've had a total argument with our architects on this one. Not so much with "gridlines" but with dimensioning. They want to dimension to finish face of walls while we want to dimension to face of stud.
Their argument: We need to set corridor widths, clearances and simple-finish distances to line up with ceiling grids, doors, etc. If we dimension to face of stud, we have to add small, cumbersome dimensions to our drawings and that's a lot of work.
Our argument: Dimensioning to the face of gypsum board or to dryvit is ridiculous as the contractor must first build the studs and footings in the first place. If you give him the finish distance, he has to do field math with fractions to lay out his walls.....pretty risky.
Architects design spaces....engineers design the material that encompasses the spaces....we each come from two different directions and thereby tend to want two different means of getting to the finish line.
