• Dimensioning a Drawing


  The purpose is to provide a clear and complete description of an object
• Dimension Lines


  • Fine broken line that contrast well with the outline of the object
  • Contacts the extension lines with long, slim arrowheads
• Extension Lines


  • Fine line which is used to clearly show the dimension limits
• Center Lines


  Used to locate centers of objects, arcs and circles and sometimes used as extension line
• Leader Line


  Straight lines leading from a dimensions value or an exploratory note to the feature on the drawing to which the notes apply
• Numerical Value


  Gives the actual distance of the objects. They are the figures for dimension values which must be lettered in vertical or inclined styles
• Notes


  Provides a means of explanatory information along with a size. Notes applying to the object as a whole are given leader in some convenient place in the drawing
• Guidelines in Dimensioning a Drawing


  • Accurate
  • Clearness
  • Completeness
  • Readability
• Unidirectional


  Also called the horizontal system. The figures are oriented to read from the bottom of the drawing. The guideline is horizontal regardless of the direction of the dimension
• Aligned


  The figures are oriented to be readable from a position perpendicular to the dimension line with the fraction bar in line with the dimension line
• AUTOCAD Dimensions


  The dimension area on the ribbon panel will look like the below image
• Linear Dimension


  Creates a linear dimension with a horizontal, vertical, or rotated dimension line. This command replaces the DIMHORIZONTAL and DIMVERTICAL command
• Aligned Dimension


  Creates a linear dimension that is aligned with the origin points of the extension line
• Aligned dimension


  Displays the true or exact value of the slanted lines, while the linear dimension does not
• ANGULAR


  Creates an angular dimension. Measures the angle between selected objects or 3 points. Object that can be selected include arcs, circles, and lines, among others.
• ARC LENGTH


  Creates an arc length dimension. Measures the distance along an arc or polyline are segment. The extension lines of an are length dimension can be orthogonal or radial. An arc symbol is displayed either above or preceding the dimension text.
• RADIUS


  Creates a radius dimension for a circle or an arc. It measures the radius of a selected circle or arc and displays the dimension text with a radius symbol in front of it.
• DIAMETER


  Creates a diameter dimension for a circle or an arc.
• ORDINATE


  Create ordinate dimensions. Measure the horizontal or vertical distanced from an origin point called the datum
• Ordinate dimensions don't indicate the measurements of any individual elements in your drawings, but instead show a position on the XY-plane. So, using the ordinate dimension feature, you can find the exact location of any point from an origin.
• JOGGED


  Create jogged dimensions for circles and arcs. The dimensions are created when the center of the circle or arc is located off the layout.
• Accurate

  • Correct values must be given
• Clearness

  • Dimensions must be placed in appropriate positions
• Completeness

  • Nothing must be left out, and nothing duplicated
• Readability

  • The appropriate line quality must be use for legibility
• Linear

  • DLI OR DIMLINEAR
• Aligned

  • DAL OR DIMALIGNED
• Angular

  • DIMANG OR DIMANGULAR
• Arc length

  • DAR OR DIMARC
• Radius

  • DIMRAD OR DIMRADIUS
• Diameter

  • DIMDIA OR DIMDIAMETER
• Ordinate

  • DIMORD OR DIMORDINATE
• Jogged

  • DIMJOGGED
