2. Dimensions Introduction Provide measurements used for construction
Found on all types of architectural drawings
Presented using lines, numerical values, and symbols, or notes and specifications
Drawings must include all dimensions needed for construction

3. Floor-Plan Dimensions
Aligned dimensioning
Dimensions are 1/8” high
(3/16” ok with computer)
(4” when using 1/4” = 1’-0” scale)
Units are in feet and inches above 12”

4. Exterior Dimensions
Overall dimensions are located outside of stud walls
First line is smallest dimension from exterior wall to center of a window, door, or inside edge of an interior wall
Second line is from outside wall to major jogs in walls
Third line is the overall room sizes
Fourth line is overall sizes

14. Designing Floor Plans Using Standard Construction Modules
Material conservation and construction labor simplification is important to consider
Standard inch construction modules are 12", 16", and 24"
When possible, design the overall building and major projections using these modules
