In Bentley Substation CE Update5 we introduced the ability to select unique phase levels for cables or bus so that they can easily be distinguished for clash detection purposes.
Specify the Sag and other desired settings and then Click OK to the Cable/Bus Object Settings dialog to complete the placement.
The Properties Control allows you to set a ‘Phase’ property which can be applied to any cable / bus that you insert while the Properties Control is running. The Phase you set in the Properties Control will drive the default Phase level in the Cable / Bus Placement Options dialog.
Note: If you want to visualize the phases in different colors you can set different colors for the levels or utilize the Thematic Manager.
