After you complete a duct run, you can move the features of that run. By moving the features, you can alter the route of the duct, connection points, or component placement. Using this ability to move features of your duct runs, you can precisely locate each feature in the layout of your HVAC systems.

You can move route objects by selecting one or more features using the Move Command on the main ribbon bar, or using the Move From and Move To  commands on the modify feature ribbon bar. We recommend that you use Move to move large sections of network to maintain the connectivity. Use Move From and Move To to move a feature.

  • You can only move a route object if (1) you have Full Control or Write access to the permission group in which the object belongs, and (2) the object's Approval Status is Working.

The various types of features that you can move in this method include:

Straight Features

The straight feature and other connected route features move subject to the following rules:

  • Moving the straight feature moves the entire leg to which the feature is connected.

  • The move direction is always perpendicular to the axis of the straight feature.

  • The end of an adjacent leg not in the plane of motion is modified to connect to the new position of the moved leg.

  • A branch feature connected to the moved leg maintains its original angle.

  • Movement stops when parts on the associated leg overlap, or when they overlap with adjacent parts on connected legs.

  • When equipment moves, the leg moves with the equipment nozzle to remain collinear with the nozzle as much as possible.

Turn Features

The turn feature and other connected route features move subject to the following rules:

  • If the branch and header are in the motion plane, the along leg feature-branch parent function and the branch feature move along the branch leg.

  • If the branch and header are not in the motion plane, the end of the branch leg, the along leg feature-branch parent function, and branch feature move to keep the branch angle constant.

  • Along leg features that are not branches maintain a position at a constant distance from the fixed end of the leg.

  • If you move a turn to a position where two adjacent legs are collinear (that is, the turn reaches 180 degrees), the software deletes the turn.

  • The turn stops moving when it starts to overlap with an adjacent along leg feature.

End Features

The end feature and other connected route features move subject to the following rules:

  • Moving the end feature edits the end feature and the length of the straight feature on its leg.

  • Moving the end feature edits the topology, or layout of the surface, of the turn feature or the branch feature if connected to another leg. The default motion plane is the connected turn feature or along leg feature with branch parent function.

  • You cannot move an end feature connected to a nozzle.

  • You must end the move when the end feature touches a nozzle or free port of the base part of a feature other than a straight feature (when the straight feature length is reduced to zero).

Branch Features

  • You cannot move branch features. You can move the branch parent feature only.

Branch Parent or Run Change Features

The branch parent or run change feature and other connected route features move subject to the following rules:

  • You can move the branch parent feature or run change feature along the associated straight feature. As you move the branch parent feature, the angle between the branch parent feature or run change feature and the branch leg appears in a dynamic readout. The angle is not applicable for run change features.

  • The size of the run change header connections is determined by the size of the connected straight feature, and therefore you cannot change the size independently.

  • You can move features only after you finish routing a duct run and placing components. Edit commands are not available until you complete routing or placement.
