HC82596: ASSEMBLY DESIGN: OFFSET CONSTRAINT , OPPOSITE ORIENTATION EMPLOYS ARBITRARY ROTATION

APAR status

• Closed as user error.

Error description

• Worbench: Assembly Design
  Function: Offset Constraint
  
  Context:
  
  In a product, insert two simple parts with one longer than the
  other to allow for the input of a offset constraint at the
  assembly design level.
  Both parts use the same origin and are relatively well
  positioned to one another without any constraints (using either
  Snap or the compass).
  
  Scenario
  Create an Offset constraint between the parallel faces of the
  ends of each part , OK
  4) Update as needed.
  5) Double-click on the constraint to edit it.
  6) Press the "More" button
  7) Select the Opposite as opposed to the Same orientation.
  8) Update (if required).
  9) Note that the alignment is now askew.
  .
  Result: An arbitrary rotation was used and the user must now
  reposition the components.
  .
  Expected Result: A simple flip around the symmetry plane common
  to both parts' offset constraint.

Comments

•  INCIDENT DIAGNOSIS:
  Part is not moved as expected by the user.
  .
   TECHNICAL EXPLAINATION
  When user selects same or opposite orientation, part makes
  a rotation of 180 degrees . Catia V5 sofware choses an
  arbitrary axis to make this rotation. It is why the part
  does not have a correct position.
  .
   CORRECT APPLICATION:
  The part is under constrainted. To keep the correct position,
  user should use a parallel constraint (angle constraint with
  parallelism option activated) to avoid an arbitrary
  rotation.
