Show Gaps

Each gap between the pieces of HVAC and/or equipment in the selected branch is identified and the optimum combination of standard and non-standard ducting straights required to fill each gap is calculated.

The gaps shown in the 3D graphical view are dependent upon if a branch, a piece of HVAC or a piece of equipment is selected in the Design Explorer, identified as the CE. If a branch is selected, all gaps in the branch will be shown. If a single piece of HVAC or equipment is selected, only the gap between the selected piece and the next piece is shown.

  1. To identify each gap and calculate the required fixed length of ducting straight to fill it, select Utilities > Autofill with Straights > Show Gaps from the main menu to display the Highlight Implied Ductwork. (HVAC) window.

  2. After selecting the required pieces of HVAC in the Design Explorer, select Apply.

    The Highlight Implied Ductwork. (HVAC) window displays the:

    • Location, the preceding component.

    • Length.

    • Calculated fixed lengths of standard and non-standard ducting straights to fill the gaps.

      All corresponding lengths of implied ducting are highlighted red in the 3D Graphical View.

  3. Selecting Unhighlight removes all the red highlighting from the 3D Graphical View.

    Note: The red highlight is also removed from the 3D graphical view, once the Highlight Implied Ductwork. (HVAC) window is dismissed.
