CAD Model Design Practices

Device/Equipment

Basic requirements for a standard CAD model of a device/equipment must have

 

  • Parametrics envelope for packaging – what is the shape and size
  • Mounting definition – how device/equipment will be mounted 
  • Mating definition – how and where device connector will meet 
  • Identification/Part Number 

Active Harness Component

Basic requirements for a standard CAD model of an active harness component must have

 

  • Parametrics envelope for packaging – what is the shape and size
  • Mounting definition – how component  will be mounted 
  • Device Mating definition – how and where device connector will meet 
  • Wire Mating definition – how and where wire will be terminated
  • Pin definition – how and where wire will be terminated
  • Connector Position Assurance (CPA) feature
  • Terminal Position Assurance (TPA) feature
  • Dress Cover definition
  • Identification/Part Number 

Passive Harness Component

Basic requirements for a standard CAD model of an passive harness component must have

 

  • Parametrics envelope for packaging – what is the shape and size
  • Mounting definition – how component  will be mounted 
  • Bundle definition – how many wires it can hold
  • Interlock definition – how iwires will be oriented
  • Identification/Part Number 

Wiring Harness

Basic requirements for a standard CAD model of a wiring harness must have

 

  • Active and passive harness components in installed position, (it is a best practice to use library interface to bring the components inside the wiring harness assembly model)
  • Wire Bundle representation
  • Wire Bundle Protective Covering representation
  • Identification/Part Number
