Gap Manager

Gaps exist between the created HVAC components and sub-components. The gaps between the created components and sub-components are left undefined and are automatically filled with implied duct work to complete the design model in the 3D view.

To fill the gaps and to also ensure the design can be prefabricated, it is necessary to specify the required fixed lengths of duct work straights between the components and sub components. These standard and non-standard straights required to fill each gap are then created in the design database and displayed in the hierarchy.

If the used specification has a standard component length for straights defined in the catalog, Gap Manager can use the defined standard straight length as the shortest allowed length to fill gaps. For information about how to set standard component lengths, see Component lengths for HVAC Gap Manager and 4.3 HVAC Editor Window.

Use the Gaps functionality to shows and fill the gaps in implied HVAC. The gaps can be filled from either direction; gaps will not be filled where there is a joint. This functionality can be applied to a SITE, ZONE or HVAC element.

Note:
Once a modification has been made, you must selected CE (located at the top left hand corner of the HVAC Gap Manager window) again.

The HVAC Gap Manager window is displayed with all the gaps in the currently selected element in the hierarchy. Any gap that is shorter then the allowable length defined in the selected specification is highlighted (these gaps will not be filled). The gaps displayed can be filtered using filter criteria.

The gaps are highlighted in the 3D view and the gaps are represented by the HVAC tube translucency setting.

If the gap is highlighted in the gap list, it is also highlighted in the 3D view.

Use the right-click menu to center on the selection or zoom to the selection in the 3D view. Both options available for selection are toggles.

Center on Selection

Centers the selected gap in the 3D view.

Zoom to Selection in 3D View

Zooms to the selected gap in the 3D view.

Fill gaps from branch head

When checked (default), fills the gaps in the currently selected HVAC from the branch head. Un-check to from the gaps from the branch tail.

If the length of the gap is more than the allowable length (defined in the specification) and the Fills gaps from branch head check box is checked, the gap is filled with a number of straights matching the standard length defined by the specification in the direction of the branch head.

Note:
Standard lengths can be manually lengthened.

Highlight gaps

Highlights the gaps in the currently selected HVAC branch in the 3D view. The gaps that are within the allowable length are translucent; short lengths are highlighted red.

Show dimensions

Labels the gaps in the currently selected HVAC branch in the 3D view.

Note:
This functionality is not enabled until the Highlight Gaps is selected.

Preview fill

Highlights the gaps to be filled in the currently selected HVAC branch in the 3D view as red.

Note:
The highlight colour is by default red - this can be modified in the Colour Settings. refer to your System Administrator for further information.

Fill gaps

Fills all the gaps in the currently selected HVAC branch.

Unfill gaps

Un fills all the gaps in the currently selected HVAC branch

Note:
Undo also un fills the gaps.
