Choosing a Standard   

This task shows you how to set the standard you need for tolerancing your part or assembly.
You must choose a standard before creating the first annotation in a document. See also Standards.

  1. Select the Tools > Options command.
    The Options dialog box is displayed.

  2. Click Mechanical Design then Functional Tolerancing and Annotation in the left-hand column.

  3. Select the Tolerancing tab.

    The Default standard at creation option provides seven conventional standards:
    • ANSI (American National Standards Institute)
    • ASME (American Society for Mechanical Engineers)
    • ASME 3D (American Society for Mechanical Engineers)
    • ISO (International Organization for Standardization)
    • ISO 3D (International Organization for Standardization)
    • JIS (Japanese Industrial Standard)
    • JIS 3D (Japanese Industrial Standard)

    See Tolerancing setting for further detail.

  4. Click OK to validate and close the dialog box.

    Note that this choice of standard must be expressed prior to specifying any tolerance.
    After any creation in the workbench, the standard may be modified but the corresponding syntax and semantic variation will not be taken into consideration.
