Trimming and Extending Dimensions

You can trim or extend all forms of linear and ordinate dimensions. To trim or extend a dimension, AutoCAD first creates an example line and then trims or extends the dimension elements to that line. The example line is an invisible line that extends between the two extension line definition points on linear dimensions. On ordinate dimensions, example lines extend from the feature location point to the endpoint of the leader.

To trim or extend an ordinate dimension, AutoCAD moves the feature location point (2) to the boundary edge perpendicular to the measured ordinate (1), so the ordinate value remains unchanged.
