HD42319: GSD \ SWEEP \ SWEEP GIVES ERROR IF INPUT CONIC CURVE PARAMETER IS REDUCED

APAR status

• Closed as program error.

Error description

• GSD \ SWEEP \ SWEEP GIVES ERROR IF INPUT
  CONIC CURVE PARAMETER IS REDUCED
  .
  1) 4 conic curves were created in the GSD
  Workbench and joined together as a line to create
  a swept surface with 4 locations for the vertices
  where values could be changed.
  2) When the conic values are 0.5 , a sweep can be
  created.
  3) Howvere if the first conic only is lowered to 0.4
  this fails with Internal error using geometrical
  package failed sweep topological error. The other
  three can be updated fine using 0.4 but not the first
  conic.
  .

Problem conclusion

• THIS PROBLEM WILL BE FIXED ON CATIA VERSION
  5 RELEASE 16 GA level.
  .
  Incident Diagnosis:
  "internal error" message raised on a specific
  draft sweep computation with imposed angle values.
  Very small inconsistency between curve lengths
  computations leads to too closed imposed
  sampling parameters and finally to an invalid knot
  vector in final sweep surface.
  .
  Correction Explanation:
  Now we check imposed sampling parameters
  equality with appropriate tolerance before
  elimination.
  .
  

Temporary fix
