HD64431: GSD: EXTRAPOLATE: EXTRAPOLATION GIVES ERROR FOR A PARTICULAR LI MIT AND BEYOND

APAR status

• Closed as Permanent restriction.

Error description

• GSD: EXTRAPOLATE: EXTRAPOLATION GIVES
  ERROR FOR A PARTICULAR LIMIT AND BEYOND.
  .
  Scenario:
  1. Load the CATPart in GSD
  2. Click on extrapolate icon
  3. Select the vertex and then the curve
  4.Choose curvature continuity
  5. Insert the value as 17mm
  6. Click OK
  .
  OBSERVATION:
  We get an error message stating that extrapolation
  cannot be created and a smaller value to be
  chosen.
  .
  EXPECTED RESULT:
  There should be no error message and the
  extrapolation should be created.
  .

Problem conclusion

• null
  ==========*===========*==========
  THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA
  .
  Diagnosis:
  The extrapolation for a specific curve failed for
  17mm
  .
  Restriction Explanation:
  This curve is made of two geometries: one a plane
  and an other one on a fillet. As we refer to the
  original CATPart that has been sent. We can
  observe that this is the extract of an edge
  bordering two faces of a solid: you could see
  clearly that one of this face is the result of a fillet
  and the other one a plane. This is the reason why
  the extrapolation failed for 17mm because the two
  geometries extrapolate together till a defined
  parameter(16 mm). After this, the geometry
  shapes diverge and no more merge is possible
  between the two geometries, hence too long
  extrapolation is not possible for this specific curve
  .
  By-Pass
  The curve have two supports: a fillet surface and a
  plane. Make an extrapolation of the fillet surface of
  20mm and intersect it with the plane. And then to
  get the result of extrapolation of 17mm, build the
  plane normal to the extract curve you want to
  extrapolate, make an offset of this plane of 17mm
  and split the intersection by this offset
  .
