Creating Zero and Negative Value Dimensions

You can specify zero and negative values for sketch dimensions. This is helpful when you want to flip an entity's sense of direction.

In the Dimension PropertyManager or the Modify dialog box, reverse the sense of a position dimension by:
  • Clicking Reverse Direction (PropertyManager) or Reverse the sense of the dimension (Modify dialog box)
  • Typing a negative number

To reverse a position dimension in a sketch:

  1. In the graphics area, select a position dimension.
  2. In the PropertyManager, under Primary Value, click Reverse Direction PM_reverse_direction.gif.
    The location of the object relative to the reference point changes to the reverse of the original value. In this sketch, the line position is fixed and the dimension to change is from the line to the top of the rectangle:

    If you click Reverse Direction PM_reverse_direction.gif, the top line in the rectangle now appears 30 units above the line:
