Component lengths for HVAC Gap Manager

The HVAC Spec Standard Length form is used to define specific standard lengths and minimum lengths for STRT components when components are used by the HVAC Gap Manager application in the Model module. If ducting gaps are shorter than the defined minimum length, the gap manager will highlight the gap but not automatically fill the gap.

To open the HVAC Spec Standard Length form, on the HVAC ribbon, under Specification, select HVAC Spec Gap Standard Length.

Use the HVAC Specs list to select a specification that is included in the opened project.

You can browse to a specification you want to edit in the Catalogue Explorer, and then select the Add Current Element button to add it to the list.

The default values for standard lengths and minimum lengths for each component can be changed by typing in new values.

Catalog requirements for standard and minimum length data

To create new length data for a new specification, the associated DATA element must be selected in the Catalogue Explorer.

To store the standard and minimum length data, the following catalog hierarchy must be available.

When new length data for a specification is created in the HVAC Spec Standard Length window, a new SUBDAT element is atuomatically created under the dataset element to store the length data.

The CATE AVEVA-SPEC-GAPS-DATA element must include the following attribute values:

• Function [Project Name], for example ACP.

• Purpose STML

The DATA 1 element must include the following attribute value:

• Purpose STML
