Tube (Bottom of Pipe) Clearance

Model Reference Manual

Piping, Ducting and Cable Trays : Component Clearance Positioning : Tube (Bottom of Pipe) Clearance

This command places the current Component on the constrained centreline so that the Tube cross-section at its Leave point is a specified clearance from another fixed object. The clearance can either be specified as a dimension along the constrained centreline in-front-of/behind the object or vertically on top/under it. If the Arrive or Leave points of the fixed object are used, then its Tube cross-section will also be considered. Using this command, pipes can be spaced on the beams of a rack by Tube-to-Tube clearance.


Examples:
BOP ONTO /BEAM	The Component will be positioned on the constrained centreline so that the Tube emerging from its Leave point is zero clearance above /BEAM (see Figure 8:28.: Tube clearance relative to a fixed object).
BOP 30 BEHIND /FLAN	The Component will be positioned on the constrained centreline so that the Tube emerging from its Leave point is 30 clear of the ‘far side’ of /FLAN (see Figure 8:28.: Tube clearance relative to a fixed object).
BOP 30 BEHIND PL OF /FLAN	As above, but 30 to the far side of the Leave Tube of /FLAN (see Figure 8:29.: Tube clearance taking into account the Tube diameter).
