User Definable Joints Set

Prior to VERSION 12.0 the joints available for use on the HVAC components were a fixed set of joints, such as FJ25, FJ30, RE , all defined in the macro hvcjoints.pmlobj. The HVAC Administrator is now able to define joints for rectangular, circular and flat oval ductwork.
There are 6 new sections (SECT) in the HVAC catalogue database.
/CADCHVACCATA-Joints-RECT
/CADCHVACCATA-Joints-CIRC
/CADCHVACCATA-Joints-FOVA
/CADCHVACCATA-Joints-RECT-Imp
/CADCHVACCATA-Joints-CIRC-Imp
/CADCHVACCATA-Joints-FOVA-Imp
These sections hold dataset elements (DATASET) for each joint, and each dataset has 7 data elements, …/DESC …/CODE …/ALPH …/NUME …/HVJA …/HVJB …/HVJC
Example:-

The data in these data elements define a joint and all its relevant information to be used and displayed in the Joints form.
The joints provided in the standard product now use this new mechanism so that HVAC Administrators can remove and create joints. The standard joints and codes available currently are:
