HD13978: 3D WIREFRAME NOT PROJECTING CORRECTLY INTO A SECTION VIEW

APAR status

• Closed as unreproducible in next release.

Error description

• 3D wireframe not projecting correctly into section
  view (accuracy proportional)
  Scenario:
  1. Open the part and the drawing.
  2. View the part. Look at the sketch "Outer / Inner
  Profile of Spring" that is within the "DRAFTING
  GEOMETRY" open body.  This sketch consists
  of four splines that outline the profile of the
  spring.
  2. Now view Section View A-A on the drawing. This
  view has been dressed-up with the addition of the
  3D wireframe from the part. Notice the wireframe
  shown in Red. It appears as a two straight lines
  within the view instead of as a a curve.
  3. Go back to the part and hide the Part Body.
  4. Return to the drawing and update the view.  Now
  the wireframe appears correctly as a curve!
  My accuracy settings are:
  3D accuracy - Proportional 0.05
  2D accuracy - Proportional 0.02
  
  .
  

Local fix

Problem conclusion

Temporary fix

Comments

• Incident Diagnosis
  The 2D view of a curve (an ellipse) is not nice
  when the 2DAccuracy is proportionnal.
  Correct Application
  The result is correct since the radius of this ellipse
  is 4030 (I do not know how it came to be), maybe
  from the projection. And since the formula for 2D
  accuracy is sag x radius of ellipse/100, if the radius
  is very big then you get an accuracy which is also
  high and the drawing is not precise.
