    Interactions        connect geometric object with function. Selecting the object activates the function.
    Joints              connecting points between models.
    ConstructionPlane   Select plane as new construction plane.

    Using function CAD:
      Mainfuncion CAD.
      Interactive creation and modification of objectcodes.

    Enable function CAD:
     Select the CAD checkbox.

    Button Help CAD:
      Information about CAD (this file).

    Button Help Func:
      Information about the selected function;
        eg for function Points - "PT cartes"

    Button Help Input:
      Information about the present active inputfield
        (how the necessary inputdata can be provided).

    Create objects:

     You have to select a CAD function. Example:
        "PT cartes" creates a point,
        "LN PT PT"  creates a line from point to point.

      All required fields are now displayed.
      The entries are made by selecting, indicating or the keyboard.
      Indicate: activate the left mouse button at the appropriate position.
      Close your inputs with the Tab key.

      The object will be stored and created with the OK button
      or with the Enter key ("Return")
      or with the right mouse button.

      When entering vectors, variables or modifiers,
      use the PageUp or PageDown buttons to select one of the existing values.

      Cancel the active function:
      - select other CAD - function or
      - key esc or
      - select the Cancel - button

    Edit objects:
      Finish and close the active CAD-function with the Esc-key.
        (several times until all inputfields are disabled)

      Select the the geometric object with the right mousebutton, function "edit".
      All parameters are entered in the input boxes.
      As an active CAD mode "MODIFY" is displayed.

      Modify the parameters (see "Creating objects" above).

      The modified object must be stored:
      - with the "OK-button
      - or with the right mousebutton.
      - or abort with button "Cancel" or Esc-key.

    Delete objects:

      Finish and close the active CAD-function with the Esc-key.
        (several times until all inputfields are disabled)

     To delete the most recently created object:
      Use Ctr-Z or the UNDO-button (red arrow to the left)
      Restore with Ctrl-Y or the REDO-button (green arrow to the right)

     To delete a particular object:
      Select the geometric object with the right mousebutten and "Delete"
      Restore with Ctrl-Y or the REDO-button (green arrow to the right)

     Delete a group of objects:
      Select the geometric object with the left mousebutten,
        (the obj is hilited and added to the group of active objects)
      delete obj with -
        - delete-key
        - or function "delete group" from menu with right mousebutton

      get position of cursor on selected object
      get parametric position of cursor on selected object
      get parentObject
