Create Ordinate Dimensions
Ordinate dimensions measure the perpendicular distance from an origin point
called the datum to a feature, such as a hole in a part. These dimensions prevent
escalating errors by maintaining accurate offsets of the features from the
datum.
Ordinate dimensions consist of an X or Y value with a leader line. X-datum
ordinate dimensions measure the distance of a feature from the datum along
the X axis. Y-datum ordinate dimensions measure the distance along the Y
axis.
