This command allows to create datum targets for ISO geometric tolerancing according to the ISO 5459 standard.

 

Creation stages / Use:

 

Select the Detailing > Datum target... command from the drop-down menu.

 

  1. Select the view on which you want to create datum target.

  2. Switch on the next step using the arrow.

  3. Create Datum target symbols.

  4. Validate the datum targets sketch.

  5. Select the datum target geometry.

 

 

 

Available options:

 

 

 

Allows to set how to display the size of the selected geometry (point, line or area). This size is displayed in the upper part of datum target.

  • Automatic:

 

- Square: square symbol before the side value.

- Circle: diameter symbol with diameter value.

- Rectangle: length × width.

- Other: empty.

  • Manual: enter the text to be displayed. The Symbols button at the end of the field allows to add special characters.

  • Export type: allows to export or not the text outside the datum target according to the Automatic, Exported and None modes. The Automatic mode will export the text when it does not contain into the datum target.

 

Examples of size display according to the selected geometry

 

 

 

 

 

 

  • Datum feature: allows to force the text value.

  • Index: This field a strictly positive integer. It is automatically incremented at the validation of the dialog.

A verification of the uniqueness of the couple letter/number is made on the 2D view.

 

 

 

 

Allows to add a movable target and define its properties.

  • Direction: allows to define the orientation of the movable target.

  • Align symbol position along movable direction: allows to force the arrow alignment with the given direction. In this case

Allows to retrieve settings of existing datum target style.

 

 

 

 

Allows to define the framing of the note and its line color.

  • Font: Displays the name and size of the font used. Use the Font cell to activate the button and then modify the settings (font, height and style). The button displays changes.

  • Unit format: allows to define units, separator, precision, ...

  • Target frame size factor: allows to define the size of the symbol. This size is the result of the factor you entered multiplied by the height of the font.

  • Movable symbol size factor: allows to define the size of the movable symbol. This size is the result of the factor you entered multiplied by the height of the font.

  • Export dimension leader extremity marker type: when the text of the size does not contain in the upper part of the symbol it can be exported (automatically or manually). This option allows to customize the type of end of the arrow.

  • Color: To use another color, select the color cell and select a new one to use.

  • Layer: Assign a layer to the element. The layer can be created on the fly by clicking the "+".

 

 

 

 

  • Extremities: allows to modify arrow extremity of the datum target.

  • Local attributes: allows to modify local attributes of the datum target.

Symbols and datum target can be created in a 3D document using annotations commands and retrieve in a drafting document in two ways:
