Straighten Previous Ducts

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

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

To straighten ducts, go to

DM HVAC->Duct Centerlines->Straighten Previous Ducts

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

Select the duct or label that is currently straight:

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

See the Previous and Next Ducts section for more information on identifying the previous ducts.
