Copyright Goodheart-Willcox Co., Inc. 208 Section 4 Reading Prints THE CONCRETE AND THE EDGE OF THE WOOD FRAMING SO THAT ALL EXTERIOR FINISHES COORDINATE PROPERLY. As noted in Unit 5, some architects follow a different practice. They start the dimensions for single-story frame buildings at the surface of the wall sheathing (which should align with the foundation wall), rather than the outside of the studs. Drawings should be checked carefully to verify the dimensioning practice used. Usually, interior walls of frame construction are dimensioned to their edges, but Dimensioning Floor Framing Normally, dimensions for exterior walls are given to the outside of the stud wall for frame and brick veneer buildings. See Figure 12-7. A note may be added to the 7 7 drawing to read: NOTE: EXTERIOR DIMENSIONS ARE TO OUTSIDE EDGE OF STUDS INTERIOR DIMENSIONS ARE ALSO TO EDGE OF STUDS WITHOUT DRYWALL OR FINISH MATERIAL.
