Floor-Plan DimensionsFloor-Plan Dimensions
Dimensioning systemAligned 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 brokenDimensions are placed above dimension lines
approximately 1/16” above lineAll dimensions are 1/8” high, use guidelines
Aligned Dimensioning Example
Aligned Dimensioning ExampleNote:Dimensions readable from the bottom of sheet and right side of sheet above the dimension line
Writing the Actual Dimension
Writing the Actual DimensionFeet and Inch/fractions: 6’-7 1/2”
Even feet no inches: 4’- 0”
Feet and zero inches/fractions: 8’- 0 3/4”
Writing the Actual Dimension
Writing the Actual Dimension
No feet only inches: 10”
No feet only inches/fractions: 8 1/2”
Only fractions of an inch: 3/4”
General Rules to Follow for Placing Dimensions
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
Spacing of Dimensioning Lines
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
Arrows or TerminatorsArrows or TerminatorsFor class project use diagonal lines for all
dimensioning terminatorsUse arrows for all leaders and callouts
Making Arrows for LeadersMaking 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”
Making Tick Marks for Terminators
Making Tick Marks for Terminators
Commonly 1/8” long at 45 degree Usually done freehand
Freehand slash all in the same
direction
A thick slash is common on manual and CADD
drawings
Dimension ProceduresDimension Procedures
Dimensions are placed on the drawing are dependant upon the type of material the walls are constructed of:
1) Frame or wood studs2) Brick or stone veneer over frame3) Solid masonry and cast concrete
Discussion today includes 3 and Interior dimensioning
Solid Masonry and Cast Concrete
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 foundationfor veneer/frame walls use 10” concrete foundation
Solid masonry walls will vary to the actual structural need of materials used
Project Sizes

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

Notice:
1) Door openings
2) Column/Beam representation
3) Footings (Dash)
4) Notes on DWG.
Interior Walls & PartitionsInterior 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
Interior DimensioningInterior Dimensioning
Assumed locations of features without dimensions given
Standard features dimensioned with a note
Dimensioning the Interior of the Plan
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

Dimension Exercise #2Dimension Exercise #2Follow 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
