HD83372: PD:IMPOSSIBLE TO CREATE 3D LINE WITH CORNER OF A SKETCH

APAR status

• Closed as Permanent restriction.

Error description

• PD:Impossible to create 3D line with corner of a
  sketch.
  .
  SCENARIO:
  1. Start CATIA V5
  2. Open the supplied CATPart
  3. Try to create a line from the point (point 2) to
  the corner of sketch.1
  4. An error message is thrown saying: The selected
  element is a non connex element.Input element
  Sketch.1\Vertex has to be connex.Use another
  element, or extract connex entity with NEAR
  operator.
  .
  RESULT:
  Line is not created from point to the corner of the
  sketch .

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  ncident Diagnosis:
  The design leads to a Generic Naming ambiguity.
  Two elements have the same name that identify
  them in the system. The 2 points cannot be
  discriminated during selection.
  .
  Restriction Explanation:
  2 subelements (endpoints of the line) coming from
  the sketches have the same inner naming (the
  same ID).This is generic naming ambiguity. It
  happens because both these points share the same
  topological neighbours (the semi-circle and the
  line). So during selection both (the 2 subelements
  with same ID) are selected at the same time.
  The behavior is a restriction in CATIA. The
  selection cannot differentiate the end points as both
  the endpoints have a single generic name in this
  case.
  .
  By-Pass:
  Following are 2 By-Passes recommended :
  A.
  Step1) Create a Point with type as 'On curve' at the
  vertex (corner) of the sketch.
  Step2) Then create a line between this point and
  point.2.This will solve the naming ambiguity and a
  line can be constructed
  .
  B.
  Break the line in the sketch into 2 parts.with the
  Break command. This will solve the naming
  ambiguity and a line can be constructed.
