Straighten Next Ducts

The Straighten Next Ducts command is used to make duct centerlines straight relative to the other centerlines to which they are connected. The first centerline you select will be treated as straight by the command. All of the centerlines that the selected centerline points to will be moved so they are either parallel or perpendicular to the selected centerline.

Any centerlines connected to the centerlines that are moved will have their starting points moved to stay connected. Their ending points will not be moved, which can result in centerlines that are no longer straight. Continue using the Straighten Next Ducts command until all of the centerlines are straight.

To straighten ducts, go to
Ribbon: DM HVAC→Ducts→  Straighten Next Ducts
Pulldown Menu: DM HVAC→Duct Centerlines→Straighten Next Ducts

You will be prompted to select the duct centerline that is straight.

Select the duct or label that is currently straight:

The next centerlines of the selected duct will be made straight.
