Architectural DimensioningPart 2 Masonry/Concrete Construction Interior Dimensioning
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
Aligned Dimensioning Example Note: Dimensions readable from the bottom of sheet and right side of sheet above the dimension line
Writing the Actual Dimension • Feet 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 • 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 • Place exterior dimensionsoutside 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 • 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 Terminators • For class project use diagonal lines for all dimensioning terminators • Use arrows for all leaders and callouts
1/8” to 3/16” 1/32” to 1/16” 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
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
Dimension Procedures • 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
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
Solid Masonry and Cast Concrete • The procedure with this type of construction: dimension to outside surfaces and to openings in the construction
Foundation Plan DimensioningExample • Notice: • 1) Door openings • Column/Beam representation • Footings (Dash) • Notes on DWG. Edge of Concrete
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
Interior Dimensioning • Assumed locations of features without dimensions given • Standard features dimensioned with a note
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
Interior Wall Dimensioning Example Face of Stud Center of Wall To actual Opening Face of Stud
2 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
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
Lab Time • First--Work on Dimensioning Exercise • Second—Work on Project Floor Plan
