Head and Tail Positioning by Bottom or Top of Pipe

Model Reference Manual

Piping, Ducting and Cable Trays : Connecting the Head or Tail : Head and Tail Positioning by Bottom or Top of Pipe

This command allows the Head or Tail of a Branch to be moved vertically to a specified clearance above or below a Design element or Point. If the Head or Tail Tube has been selected, then its cross-section will be taken into account. (Otherwise the HPOS or TPOS will be moved to the specified clearance, as no Tube geometry is available.)


Example:
BOP ONTO /BEAM (At the Head)	This will position the Tube on top of /BEAM with a clearance of 0.
TOP UNDER U3000 (At the Tail)	This will position the Tail under the elevation U3000 with a clearance of 0.

Note:

If no Tube can be found emerging from the point specified, then only the point’s position can be used.
