How to Change the Origin of Ordinate Dimensions in a Drawing

Problem

In SOLIDWORKS Drawings, Ordinate dimensions are dimensions measured from a user-defined origin in a drawing. At some point, the user may want to move the origin. This article explains how to change the origin so that the ordinate dimensions will update to match the new origin. The example drawing below starts with the Origin at the left.

Solution

  1. Open SOLIDWORKS and open the Drawing
  2. In SOLIDWORKS 2023 or older, drag the origin dimension leader to a new edge. The example will drag it to the rightmost edge.
