Creating Horizontal Linear Dimensions

The HorizontalDimension command lets you create horizontal linear dimensions. The horizontal distance between the defining points is measured and the dimension line is parallel to the X-axis.

To create horizontal linear dimensions:

1. Type HorizontalDimension at the command prompt.
2. In the graphics area, click to set the first and second extension line origins.
   
   - or -
   
   Press Enter, then select an entity to dimension. You can specify Lines, PolyLines, Circles, and Arcs. The start and end points of linear entities, or the diameter of circular entities are measured.
3. Click in the graphics area to place the dimension lines or specify an option:
   
   Angle, Note, or Text: See Editing and Formatting Dimension Text.
   
   The measurement is placed as dimension text based on the definitions of the current DimensionStyle.

  To dimension the real length of Lines not parallel to the X- or Y-axis of the coordinate system, use the ParallelDimension command.
