BOP TOP ONTOP UNDER INFRONT BEHIND
Description
This command places the current Component on the constrained centerline 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 centerline 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 centerlines so that the Tube emerging from its Leave point is zero clearance above /BEAM (refer to the Tube clearance relative to a fixed object image). |
|
BOP 30 BEHIND /FLAN |
The Component will be positioned on the constrained centerline so that the Tube emerging from its Leave point is 30 clear of the ‘far side’ of /FLAN (refer to the Tube clearance relative to a fixed object image). |
|
BOP 30 BEHIND PL OF /FLAN |
As above, but 30 to the far side of the Leave Tube of /FLAN (refer to the Tube clearance taking into account the Tube diameter image). |
