Controls the dimension and weight units that display in the sketch. The default settings shown on the Working Units tab are read from the project defaults that you set in I-Configure. If you are creating a new file, you are able to override the default values, but only for the new pipeline.
Coordinates
Specifies the dimension units that display for coordinate data in millimeters (mm), meters (m), or feet/inches (ft/in).
Bolt lengths and diameters
Specifies the dimension units that display for bolt lengths and diameters in millimeters (mm) or feet/inches (ft/in).
Weights
Specifies the weight units that display on the sketch in kilograms (kg) or pounds (lb).
Dimension precision
Controls the display of dimension line lengths in the sketch. When you select Round dimension line lengths to nearest mm, the software rounds the dimension up or down to the nearest whole number. The option has no effect on imperial units of measure.
