The Offset Conduit command is used to create parallel runs of conduit. After inserting a single conduit run between two panels, use this command to create the additional conduit runs. The parallel runs can be either vertically or horizontally offset to the first conduit you inserted.
To offset a conduit run, go to
Ribbon: DM Electrical->3D-BIM-> 
Offset Conduit
Pulldown Menu: DM Electrical->Conduits->Offset Conduit
You will be prompted to enter the distance of the offset.
Specify offset distance:
You will then be prompted to identify which conduit is to be offset.
Select conduit to offset:
All of the conduits connected to the one you selected will be duplicated and offset.
The Inside Radius dialog box will appear.
See the Adjust Conduit Radius section for more information about setting the inside radius.
Select the Radius Criteria and press the OK button. You will be prompted to specify on which side the offset conduit is to be located.
Specify point on side to offset or [Up/Down/Multiple]:
Specify point: The conduit run will be offset to the side you select on the drawing.
Up: The conduit will be offset up. Use this setting to create vertical parallel runs of conduit.
Down: The conduit will be offset down. Use this setting to create vertical parallel runs of conduit.
Multiple: You will be able to offset the conduit multiple times. The Inside Radius will be used to set the radius value on all of the conduits that are offset.
After selecting Multiple, you will then be prompted to specify the directions to offset the conduit run, using the same options as before.
Specify point on side to offset or [Up/Down/<select Next object>]:
select Next object: Finishing offsetting the selected conduit and select a new conduit to offset.
