Connecting the Head or Tail

Model Reference Manual

Piping, Ducting and Cable Trays : Connecting the Head or Tail

The CONNECT command, when applied to Branches (or Hangers), sets up the Head or Tail to match exactly the item to which it has been connected. For example, if the Head is connected to a 3-inch flanged-faced nozzle at E3000 and pointing North, the CONNECT command will set all the Head attributes (HBOR, HCON, HPOS and HDIR) to corresponding values. In addition, the Head and Nozzle are logically ‘tied together’ by two attributes which ‘point’ to each other - the Nozzle CREF will point to the Branch, and the Branch HREF (Head Reference) will point to the Nozzle.

Examples:
CONN PH TO /1205-N5 (Where /1205-N5 is a Nozzle)	The Head attributes of the current element (Branch or Hanger) are set to match the position, orientation, bore and connection type of the Nozzle (see Figure 8:1.: Connecting a Branch Head or Tail).
CONN PT TO LAST MEM	The Tail attributes of the current element will be set to match the Leave Point of the last Component (that is not an Attachment point).
CONN PT TO /100-A8/T2 (Where /100-A8/T2 is a TEE)	The Tail attributes of the current element will be set to match the free p-point on the specified TEE (see Figure 8:1.: Connecting a Branch Head or Tail).
CONN PT TO P4 OF /VF205 (Where /VF205 is a VFWA.)	The Tail attributes of the current element will be set to match the specified p-point.
CONN PH TO PT OF /100-A8/1 (Where /100-A8/1 is another Branch)	The Head attributes of the current element will be set to match the Tail of the specified Branch.
CONN PH TO ID NOZZ@	As in the first example, but with the Nozzle identified by cursor selection.
