Adding Clashes to the Approval List

Keywords

APPROVE

Description

Adds clashes to the approval list in any of the following ways:

• By specifically identifying a known clash between two named items

• By specifically identifying a known clash by means of its reference number in the latest clash report

• By generally referring to actual or potential clashes between named items; either before or after running a check to see what clashes exist

• By specifying actual or potential clashes within a single named element

  Approved clashes will be omitted from clash reports regardless of which way round the interfering items are specified in the obstruction list and the check list in subsequent clash-checking runs.

  Examples
  APPROVE HS TOUCH BOX1 OF /EQUI1 WITH /GASK1 OF /BRAN2	Approves hard/soft touch between named items (and any lower level touches; for example, HI, SS)
  APPROVE 5	Approves the fifth clash in most recent clash report
  APPROVE SIGNIF 5	Approves fifth clash in most recent clash report at significant element level, rather than at primitive level; where the significant elements are: Sites, Zones, Pipes, Branches, Equipments, Structures, Substructures, Hangers, Restraints, Ptracks, Frameworks, and Subframeworks
  APPROVE II CLASH /BRAN1-1 WITH /ZONE.EQUIP	Approves all Insulation/Insulation clashes between any elements below /BRAN1-1 and any elements below /ZONE.EQUIP
  APPROVE /ZONE.EQUIP WITH /ZONE.STEELW	Approves all types of clash between members of the named zones
  APPROVE HS CLASH /ZONE.EQUIP WITH /ZONE.EQUIP	Approves all hard/soft clashes between members of /ZONE.EQUIP (and any lower level clashes, touches or clearances)
