HD93134: SWEEP SURFACE IS NOT CREATED BY USING TWO GUIDE CURVE

APAR status

• Closed as Permanent restriction.

Error description

• SCENARIO:
  1Create a Guide1, Guide2, Profile1, PT1 and PT2 elements
  
  2. Create Sweep
  
  1) Click Sweep Icon
  
  2) Select Explicit as Profile type
  
  3) Select With two guide curves as Subtype
  
  4) Select Profile as Profile
  
  5) Select Guide2 as Guide curve 1
  
   6) Select Guide1 as Guide curve 2
  
  7) Click OK Button
  
  .
  PROBLEM:
  Surface is not created along Guide1.
  .
  EXPECTED RESULT:
  Surface should be created along Guide1.

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN CATIA.
  Additional Closure Information:
  Incident Diagnosis:
  The sweep does not follow the second guide.
  .
  Reason:
  If you do not explicitly select anchor points or anchor
  direction, they are automatically computed if the profile is
  planar.
  The anchor points are computed as follows:
  for Anchor point 1: intersection between the profile plane
  and first Guide curve.
  for Anchor point 2: intersection between the plane, passing
  through first Anchor point and normal to the spine, with
  second Guide curve.
  In this case, the sweep cannot follow the second guide. It is
  mathematically impossible because the profile is not in the
  spine plane.
