HD65827: GSD : THE DISPLAY OF REVOLUTE SURFACE DOES NOT WORK EVEN AFTER CREATING IT WITH FIXED 3D ACCURACY EQUAL TO 0.02

APAR status

• Closed as Permanent restriction.

Error description

• CASE: 3D Accuracy = 0.02
  < Tool / Option Setting >
  Options / General/ Display / "Performance" tab /
  3D Accuracy/ "Fixed = 0.02"
  .
  < Process >
  1) Start CATIA V5
  2) Open the provided CATPart file
  Workbench : "GSD"
  ==> the "Incident Report" displays
  and "Revolute.1" surface does not display in the
  geometry. These are Problems!!
  .
  CASE: 3D Accuracy = 0.2
  .
  < Tool / Option Setting >
  Options / General/ Display / "Performance" tab /
  3D Accuracy/ "Fixed = 0.2"
  .
  < Process >
  1) Start CATIA V5
  2) Open the provided CATPart file
  Workbench : "GSD"
  ==> the Color of "Revolute.1" surface is not right.
  This is the Problem
  .
  < Result to expect >
  Even if 3D Accuracy sets to what value,
  the Revolute surface should be displayed correctly.
  .
  < Remark >
  How the "Revolute.1" surface has been created ?
  -Options / General/ Display / "Performance" tab /
  3D Accuracy/"Fixed = 0.02"
  -Create "Revolve" element.

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  .
  Incident Diagnosis :
  THE DISPLAY OF REVOLUTE SURFACE DOES NOT
  WORK EVEN AFTER CREATING IT WITH FIXED 3D
  ACCURACY EQUAL TO 0.02
  .
  Restriction Explanation :
  The problem is due to too many Triangles. The
  Tessellation of huge Revol Surface is made (this is
  almost the same than a Sphere with a radius equal
  to 187287mm. With a 0.2 Sag, there are more than
  2 million triangles. With a 0.02 Sag, there will be
  minimum 10 times higher : there is no enough
  memory for such operations.
  .
  By-Pass :
  Choose the proportional and appropriate 3D Sag.
