HD71222: FTA (PART) / DATUM TARGET DEFINITION DOES NOT FOLLOW FORM OF GE OMETRY

APAR status

• Closed as documentation error.

Error description

• FTA (Part) / Datum target Definition does not follow
  form of geometry
  .
  Process
  1) Start CATIA : "V5R17SP3" .
  2) Open the file : "xx98xx.CATPart" .
  Workbench : "FTA" .
  3)Expand "Datums" in the tree.
  4)Double click "Simple Datum.1(A)" in the tree.
  The "Datum Definition" window is opened.
  5)Click "Add" button in the tree. The "Datum
  Target" window is opened.
  6)Activate "Circular" .
  7)Input "10mm" in the box.
  8)Click "Fill1" in the tree. The "Datum Target"
  window . The "Datum Target" is created.
  .
  Problem1:
  The notation of "Datum Target" can be created with
  a circle although the associated Form is a
  rectangle.
  And the dimensions of a "Datum Target" are not
  reflected in the dimensions of a "Target Element".
  "Target Element" Type : Rectangular ,
  Dimension: 40x40
  "Datum Target" = Type : Circular , Dimension : 10
  .
  9)Click "Add" button in the tree. The "Datum
  Target" window is opened.
  10)Activate "Rectangular".
  11) Input "15mm" in the two box.
  12)Click "Fill.2" in the tree. The notation of "Datum
  Target" can be created with a "Circular" although
  the associated Form is a "Rectangular".
  .
  Problem 2:
  And the dimensions of a "Datum Target" are not
  reflected in the dimensions of a "Target Element".
  "Target Element" = Type : Circular ,
  Dimension : 55
  "Datum Target" = Type : Rectangular , Dimension:
  15x15
  .
  Expected Result: The contents of a setting
  of "Datum Target" should be follow the Form
  of "Target Elements" (ex: Fill) .
  A : The Form of Target Element should be reflected
  in a setup of a Form of Datum target.
  1.If "Target Element" is "Circular" ,"Datum Target"
  should be "Circular" and " Rectangular " .
  2.If "Target Element" is " Rectangular " ,"Datum
  Target" should be "Circular" and " Rectangular " .

Problem conclusion

• THIS MODIFICATION WILL BE INCLUDED IN THE
  DOCUMENTATION DELIVERED WITH CATIA
  VERSION 5 RELEASE 19 GA LEVEL.
  Documentation Reference
  3D Functional Tolerancing and Annotation
  User Tasks
  Creating a Datum and Datum Targets
  .
  MODIFICATION:
  In the 'Creating a Datum and Datum Targets' topic,
  added following information:
  You can select the geometry (which should be
  inside the geometry referenced by the datum
  feature).
  If selected geometry is a point or vertex, the three
  options are available to specify the form (point,
  circle, rectangle) and the size of the limited zone.
  If the selected geometry is a curve or a surface,
  the three options are disabled. This is because the
  selected curve or surface itself defines the form
  and size of the limited zone.
  .
  In the 'Creating Datum Targets', added following
  information:
  If the datum target is created on a point geometry
  then you can specify the form (point, circle and
  rectangle) and the size of the limited zone.
  Otherwise the options are disabled.
  .
  Additonal Information: The behavior is changed on
  R18SP05 and R19 GA. Hence the Documentation is
  updated in accordance with it on R19 GA.
