2. Review

3. Floor-Plan Dimensions
Dimensioning system
Aligned dimensioning--dimensions are placed in line with the dimension lines and are read from the bottom or right side of the drawing sheet
Dimension lines are solid (Thin) and not broken
Dimensions are placed above dimension lines approximately 1/16” above line
All dimensions are 1/8” high, use guidelines

4. Aligned Dimensioning Example
Note:
Dimensions readable from the bottom of sheet and right side of sheet above the
dimension line

5. Writing the Actual Dimension
Feet and Inch/fractions: ’-7 1/2”
Even feet no inches: 4’- 0”
Feet and zero inches/fractions: 8’- 0 3/4”

6. Writing the Actual Dimension
No feet only inches: 10”
No feet only inches/fractions: 8 1/2”
Only fractions of an inch: /4”

7. General Rules to Follow for Placing Dimensions
Place exterior dimensions outside the floor plan, starting with the smallest first, then subtotals and finally overall totals
Place interior dimensions inside the floor plan in string fashion. Several strings may be required both horizontally and vertically

8. Spacing of Dimensioning Lines
First string of dimensions are usually placed about 3/8” to 1” from the object depending upon the amount of space available
Second string of dimensions are placed 3/8” to 1/2” from the first string of dimensions
Additional strings of dimensions are spaced like the second string of dimensions

9. Arrows or Terminators
For class project use diagonal lines for all dimensioning terminators
Use arrows for all leaders and callouts

10. Making Arrows for Leaders
Arrows for dimensions and leader lines should be the same
Arrows usually have a set proportion and have a slender look to them
1/8” to 3/16”
1/32” to 1/16”

11. Making Tick Marks for Terminators
Commonly 1/8” long at 45 degree
Usually done freehand
A thick slash is common on manual and CADD drawings
Freehand slash all in the same direction

12. Dimension Procedures 2) Brick or stone veneer over frame
Dimensions are placed on the drawing are dependant upon the type of material the walls are constructed of:
1) Frame or wood studs
2) Brick or stone veneer over frame
3) Solid masonry and cast concrete
Discussion today includes 3 and Interior dimensioning

13. Solid Masonry and Cast Concrete
Common wall thickness for cast concrete:
6”, 8”, 9”, 10”, and 12”
Typical residential practice for concrete wall thickness:
for frame walls use 8” concrete foundation
for veneer/frame walls use 10” concrete foundation
Solid masonry walls will vary to the actual structural need of materials used
Project Sizes

14. Solid Masonry and Cast Concrete
The procedure with this type of construction: dimension to outside surfaces and to openings in the construction

15. Foundation Plan Dimensioning Example
Notice:
1) Door openings
Column/Beam representation
Footings (Dash)
Notes on DWG.
Edge of Concrete

16. Interior Walls & Partitions
Typical interior walls are drafted 5” but are actually 4 1/2”
When dimensioning to interior walls the common practice is to locate the center of the wall
Generally the placement of interior dimensions is along a string of dimensions going the full length or width of house

17. Interior Dimensioning
Assumed locations of features without dimensions given
Standard features dimensioned with a note

18. Dimensioning the Interior of the Plan
Locate the center of interior partitions with short extension line
Place short extension line at exterior face of stud (exterior walls only)
Place string of dimensions locating these features

19. Interior Wall Dimensioning Example
Face of Stud
Center of Wall
To actual Opening
Face of Stud

20. Dimension Exercise #2 Follow all rules as they apply:
#1—Dimension exterior horizontal only of the concrete floor plan
#2--Dimension interior horizontally and vertical then Dimension exterior horizontal 2

21. Example of Dimension Exercise
Remember:
Place dimensions in string fashion
Face of stud exterior walls
Center of interior walls
Add extension lines and tick marks

22. Lab Time First--Work on Dimensioning Exercise
Second—Work on Project Floor Plan
