A Location_dimension is the dimension of the distance between two elements (origin and target).
A Location_dimension is a type of Geometric_dimension.
Each Location_dimension is a Curved_distance_dimension, a Linear_distance_dimension, or an Angular_location_dimension.
The data associated with a Location_dimension are the following:
The directed specifies a Boolean value designating the importance of direction for measuring a Location_dimension. If the value is 'true' the Location_dimension is measured from origin to target. A value of 'false' indicates that the direction for measuring Location_dimension is inconsequential.
NOTE This value may be used to indicate the sense of measurement of the distance to be privileged during metrology checks.
The description specifies additional information about the Location_dimension.
See location_dimension to multi_language_string for the application assertion.
The description need not be specified for a particular Location_dimension.
If present, there shall be exactly one object that defines the description for a Location_dimension.
The origin specifies the geometric or annotation element that is the origin for the Location_dimension.
See location_dimension to annotation_curve, location_dimension to constructive_geometric_element, location_dimension to derived_geometry, and location_dimension to shape_element for the application assertions.
There shall be exactly one object that defines the origin for a Location_dimension.
The target specifies the geometric or annotation element that is the target for the Location_dimension.
See location_dimension to annotation_curve, location_dimension to constructive_geometric_element, location_dimension to derived_geometry, and location_dimension to shape_element for the application assertions.
There shall be exactly one object that defines the target for a Location_dimension.
