2. Foot &/or inch marks are normally used on architectural dimensions. Sometimes a dash is used 8-4 or 8’4”.

3. Overall dimensions for the length of the building should be placed outside other dimensions.

4. Framed interior walls are dimensioned to the center of partitions. 5. Dimensions that cannot be seen on the floor plan or those too

small to place on the drawn plan are noted with leaders.6. Windows, doors, and beams are dimensioned to their centerlines.7. Architectural dimensions always refer to the actual size of building

regardless of the scale of the drawing.
