When the Conduit tool is selected, the Modify | Place Conduit tab provides the following options for placing conduit:
Justification. Opens the Justification Settings dialog where you can specify Horizontal Justification, Horizontal Offset, and Vertical Justification for the conduit.
Automatically Connect. Lets you automatically connect to the snaps on a component when starting or ending a conduit segment. This option is useful for connecting segments at different elevations. However, when drawing conduit at a different offset or to disable snapping to an non-MEP element, clear Automatically Connect to avoid making an unintentional connection.
Tag on Placement. Applies the default annotation tag to a conduit segment when it is placed in the view.
