Error description

• PART:  MIRROR FAILS WHEN THE PAD IS CREATED
  WITH REFERENCE LINE DIRECTION.
  .
  SCENARIO.
  1. Start CATIA V5R18 SP03.
  2. Open file TEST.CATPart.
  3. Create Pad. During creation of Pad, select
  Sketch.1 for selection of
  profile and select Line.1 for reference of direction
  and specify 100mm
  for length.
  4. Select Pad.1 for Object to mirror and select
  Plane.2 for Mirroring
  element.
  Result A:-Warning message appears. Then click
  Yes button in Warning
  message popup window. Message of Update Error
  appears and mirroring fails. This is the problem.
  5. Click cancel and close the Mirror definition dialog
  box.
  6. Delete the Pad and recreate it without the
  Reference line.
  7. Mirror the Pad about Plane.2. The mirror is
  performed without any error.
  Error: Mirror fails when the Pad is created with
  Reference Line direction.

Comments

• Incident Diagnosis.
  Reference Line is created on YZ plane and Pad is
  created with this Line as direction. When Mirror of
  Pad feature is performed, a warning message is
  thrown which states that the wireframe elements
  would not be transformed. This implies that the
  direction of Pad under Mirror would not be
  transformed. It would still be the same Line.
  Now, note that Mirroring Plane is created at an
  angle 45 degrees to YZ plane. When user tries to
  Mirror Pad feature with respect to this Plane, Pad
  under Mirror would be created at 45 degrees to the
  Plane i.e. 90 degrees to YZ plane. This makes the
  direction of Pad under Mirror parallel to its sketch.
  This causes an error being thrown "Impossible to
  compute the geometry" and results in Mirror going
  into Update error. Hence only at this specific value
  of mirroring plane angle the mirror fails.
  .
  When the user instead of Pad feature selects the
  Partbody, in this case Mirror command only selects
  the outer skin of the Current solid and not the only
  Pad feature. And during any type of transformation
  when a particular feature is selected its
  specifications are also taken in account while when
  complete or current solid is selected then none of
  the features specifications are taken in account.
  Hence in this case direction of the Pad is not the
  Line but it is change to default that is Normal to
  profile and the mirrored solid is created correctly.
  .
  Correct Application.
  Change the angle for Mirroring Plane and Mirror
  would work fine.
