Summary
Ordinate dimensions measure the horizontal or vertical 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.
List of Prompts
The following prompts are displayed.
Specify feature location: Specify a point or snap to an object
Specify
leader endpoint (page 309) or [Xdatum (page 309)/Ydatum
(page 310)/Mtext (page 310)/Text (page 310)/Angle (page 310)]:
Specify a point or enter an option
Leader Endpoint Specification Uses the difference between the feature
location and the leader endpoint to determine whether it is an X or a Y
ordinate dimension. If the difference in the Y ordinate is greater, the dimension
measures the X ordinate. Otherwise, it measures the Y ordinate.
Xdatum Measures the X ordinate and determines the orientation of the leader
line and dimension text. The Leader Endpoint prompt is displayed, where you
can specify the endpoint.
