Use the HVAC Joints functionality to add and/or modify the joints for custom components, to display each joint for the currently selected element and the others in the HVAC branch, display the configuration (arrive/leave), view a close up of the currently selected element in the 3D view and carry out compatibility checks. Some of the joints have geometry which can seen in the 3D view.
Note:
Joints can be modelled into specifications, but there will be no compatibility checks.
The functionality available in the PIPING discipline (COCO tables) is not available
in this release.

The HVAC Joints window is initially displayed empty. To display a list of available joints, select the required HVAC element in the 3D view or model hierarchy. The default joint is highlighted in the list. These joints are governed by the custom settings.
Note:
This list of available joints can be filtered.
The functionality available for selection is dependent upon the currently selected element of the HVAC branch. For example - if the currently selected element is a standard HVAC component with an arrive and leave, branch connector or threeway HVAC element.
