Head or Tail Positioning Using End Components

Model Reference Manual

Piping, Ducting and Cable Trays : Connecting the Head or Tail : Head or Tail Positioning Using End Components

These commands allow the Head or Tail position to be set by using the end Component in that Branch or Hanger. This will normally occur when the Tail is to finish with a piece of variable length Tube. This command treats the Tail position as a pseudo-Component and places it at the specified point along the previous Component’s Leave p-point direction. If the Head is to be positioned in this way, Backwards Routing Mode must be in force.


Example:
POS PT DISTANCE 1000	The TPOS attribute will be set to the position 1000 from the leave p-point of the last Branch member (i.e. previous Component).
POS PH THROUGH E3000 (In BACKWARDS mode)	The HPOS attribute will be set to the intersection between the line from the Arrive p-point of the Previous Component and the perpendicular plane through E3000 N0 U0 in owner coordinates.
