Architectural Dimensioning Part 2 Masonry/Concrete Construction Interior Dimensioning

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

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

Writing the Actual Dimension t. Feet and Inch/fractions: 6’-7 1/2” feet no inches: 4’- and zero inches/fractions: 8’- 0 t. Even 0” t. Feet 3/4”

Writing the Actual Dimension t. No feet only inches: 10” t. No feet only inches/fractions: 8 1/2” t. Only 3/4” fractions of an inch:

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

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

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

Making Arrows for Leaders t. Arrows for dimensions and leader lines should be the same t. 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 t. Commonly 1/8” long at 45 degree t. Usually done freehand A thick slash is common on manual and CADD drawings Freehand slash all in the same direction

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

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

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

Foundation Plan Dimensioning Example Notice: 1) Door openings 2) Column/Beam representation 3) Footings (Dash) 4) Notes on DWG. te e r c n o C f o Edge

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

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

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

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

Example of Dimension Exercise t Remember: t Place dimensions in string fashion t Face of stud exterior walls t Center of interior walls t Add extension
