APAR status

• Closed as suggestion for future release.

Error description

• SKETCHER \ SURFACE PROJECTION ONTO SKETCH
  IS NOT POSSIBLE WITH TREE SELECTION.
  .
  SCENARIO:
  1) Start CATIA.
  2) Open the file: Bracket_Error.CATPart.
  Workbench: Sketcher
  3) Select Surface.317ﾨ from Part tree.
  4) Select Icon ﾨProject 3D Elementsﾨ Projection
  fails. Error is displayed. This is the problem.
  5) Click OK.
  6) Pre-select Surface.317 in geometry area.
  7) Then click the Project 3D Elements icon.
  Projection is done without any error.

  Incident Diagnosis:
  It is not possible to directly create the projection of
  the feature Surface.317 onto a sketch with a VB
  script.
  User reports that it is also not possible to
  interactively project the selected feature
  Surface.317 whereas it is possible to create a
  projection if the face corresponding to Surface.317
  was selected. User believes that allowing the
  projection of the feature Surface.317 in the
  command will enable the projection in a VB script.
  This is not the case.
  .
  The geometry of Surface.317 is a single face.
  There is a hole in this face, thus the face has 2
  boundaries (internal and external). The sketch
  projection operator does not allow to project a face
  with more than one boundary. The VB projection
  calls the projection operator, that's why the VB
  script fails. This is normal behavior.
  .
  The projection operator also fails in the project
  command, both for the feature and for the face.
  Nevertheless the command does extra work when
  the projected object is a single face and the
  operator fails (the failure is not reported to the
  user).
  The bounding edges of the face are automatically
  projected one by one, creating as many Projection
  features in the sketch as edges. For each of these
  features, the projection operator succeeds. This is
  not done when the feature is selected because the
  result of a feature can be different from a single
  face. This is normal behavior also. This can be
  done in a VB script (see attached file
  Macro_projectingFace.catvbs), or with CAA APIs.
  .
  Development Request Justification:
  Modifying the command as suggested by the
  user is considered by DS to be an enhancement.
  Furthermore this would not allow the customer to
  create a projection of Surface.317 in a VB script.
  DS thinks that the real solution would be to allow
  users to specify a near element when defining a
  projection, interactively and in VB script.
  This would enable the projection operator to
  discriminate between the various boundaries of the
  geometry of a feature when it is needed.
  Something similar can be done in a VB script by
  using GSD Boundary + Near (see attached file
  Macro_usingBoundaries.catvbs)
  .
  Answer and By-Pass:
  See provided catvbs files.
