  .
  Setup of the options:
  1) Select"Tools" > "Options" by menu bar.
  =>"Option" dialog box is displayed.
  2) Select "Functional Tolerancing & Annotation" on
  the tree.
  3) Select "Tolerancing" tab.
  4) Activate the "Always try to create semantic
  tolerances and dimensions".
  5) Activate the "Always try to create semantic
  general tolerances on dimensions".
  6) Activate the "Non-semantic tolerance creation
  allowed".
  7) Activate the "Non-semantic dimension creation
  allowed".
  8) Click "OK".

  Scenario
  0) Start CATIA V5R16SP2
  1) Open the file : "T8390.CATPart".
  Workbench : "Functional Tolerancing & Annotation".
  .
  // In the case of 2 faces. //
  2) Click "Tolerancing Advisor" icon.
  =>"Semantic Tolerancing Advisor" dialog box is
  displayed.
  3) Select 1 face in the solid on the geometry area.
  (Please see the "T8390.ppt" we send.)
  4) Select 1 face in the solid by "Ctrl Key" on the
  geometry area.
  (Please see the "T8390.ppt" we send.)
  =>"Semantic Tolerancing Advisor" dialog box is
  expanded.
  =>"Tab / slot" is displayed in the "Geometric
  feature type" cell.
  =>"Distance Creation" button exist in the dialog
  box.
  5) Click "Distance Creation" button.
  =>"Limit of Size Definition" dialog box is displayed.
  6) Click "OK".
  =>"Semantic Tolerancing Advisor" dialog box is
  displayed.
  7) Click "Close".
  =>"Linear Size" type of dimension is created.
  (This is the right behavior.)
  .
  // In the case of 2 holes. //
  8) Click "Tolerancing Advisor" icon.
  =>"Semantic Tolerancing Advisor" dialog box is
  displayed.
  9) Select 1 hole in the solid on the geometry area.
  (Please see the "T8390.ppt" we send.)
  10) Select 1 hole in the solid by "Ctrl Key" on the
  geometry area. (see the "T8390.ppt")
  =>"Semantic Tolerancing Advisor" dialog box is
  expanded.
  =>"Tab / slot" is not exist in the "Geometric
  feature type" cell.
  >>>This is problem.
  =>"Distance Creation" button can not select.
  >>>This is problem.
  =>"Linear Size" type of dimension is not created.
  >>>This is problem.
  .
  < Result >
  "Linear Size" type of dimension is not created
  when a hole and a hole are specified
  by "Tolerancing Advisor".
  >>>This is problem.
  .
  < Result to expect >
  "Tab / slot" should be displayed in the "Geometric
  feature type" cell when a hole and a hole are
  specified by "Tolerancing Advisor".
  ("Distance Creation" button should be displayed.)

  LINEAR SIZE TYPE OF DIMENSION IS NOT

  ADVISOR
  .
  Correct Application
  ISO standards do recommend to restrict the use
  toleranced dimensions to feature of size.
  FTA is supporting the following feature of size
  dimensions:
  - Diameter of cylinder, circle or sphere
  - Distance between 2 planar parallel faces
  - Distance between 2 cylidrical parallel faces that
  have the same diameter
  - Cone angle
  - Angle between 2 planar secant faces
  .
  For feature of size made of 2 components, FTA is
  explicitely identifying the feature of size in
  the "Geometric feature type" field of the
  Tolerancing Advisor.
  The "Tab/Slot" type is for feature of size made of 2
  planar parallel faces.
  The "Angular Tab/Slot" type is for feature of size
  made of 2 planar secant faces.
  The "Cylindrical Pin/Hole" type is for feature of size
  made of 2 cylidrical parallel faces that have the
  same diameter.
  .
  ISO standards allow also creating toleranced
  dimensions between 2 geometrical elements that
  do no correspond to a feature of size.
  These cases are supported by the Tolerancing
  Advisor thru the "Related" Geometric feature type.
  User has to use this type in the case that
  corresponds to the current incident description.
