Error description

• DMUNAV:POSITION OF ORIGIN CHANGED
  INCORRECTLY IF SKETCH IS SHOWED.
  .
  SCENARIO:
  1.Open "PRODUCT1.CATProduct".
  2.Cylinder part is defined from sketch on XY plane.
  3.Sketch is hide is initially.
  4. Change to DMU Space Analysis WB, and select
  Section command, then select Positioning tab,
  and Edit Position and dimensions icon.
  5. Confirm that the Z Value of Origin is 50mm, then
  close and cancel the section definition.
  6. Now show the sketch of the Pad.
  7. Select Section command again, then select
  Positioning tab, and Edit Position and dimensions
  icon.
  8. Confirm that the Z Value of Origin is 33.032mm.
  It is incorrect.
  9. Close and cancel section definition.
  10. Change to GSD workbench.
  11. Select Extract command, then select bottom
  surface to extract.
  12.Return to DMU Space Analysis Workbench and
  select section command,then select Positioning tab,
  Edit Position and dimensions icon.
  13.Confirm that the Z Value of Origin is
  32.962mm.It is incorrect.
  14.Close and cancel section definition.
  .
  RESULT:
  - Position of origin is changing if we try to show the
  sketch.
  .
  EXPECTED RESULT:
  -Position of origin should not be changed if we
  show sketch or other features in the bounding
  sphere.

  Incident Diagnosis:
  DMUNAV:POSITION OF ORIGIN CHANGED
  INCORRECTLY IF SKETCH IS SHOWED.
  .
  Correct Application:
  -The position of section plane depends on shown
  elements and it is computed on their bounding
  elements.
  -In this scenario, the sketch has a BE and if you
  show it, the position of plane will be a little
  bit different because of the global bounding box of
  the assembly (part+ sketch).
  .
  - In the DOC: Positioning planes using the edit
  Position and Dimensions COmmand
  .
  1. Enter values in Origin X, Y or Z boxes to
  position the center of the plane with respect to
  the absolute system coordinates entered.
  By default, the center of the plane coincides with
  the center of the bounding sphere around the
  products in the CURRENT selection.
  2.and even in this part in DOC: Creating section
  planes/About Section planes
  .
  The plane is created parallel to absolute
  coordinates Y, Z. The center of the plane is
  located at the center of the bounding sphere
  around the products in the selection you defined
  .
