Standards

Standards (such as ISO, JIS, ANSI, ASME, etc. or company standards) specify the properties and styles of tolerancing and annotation elements such as dimensions, annotations, etc. so that they will be applied to all elements of a given type within a single part or product, as well as in all parts or products which use the same parent standard.

Standards are managed by an administrator. Each standard is defined in an XML file, which makes it possible to customize globally the appearance and behavior of tolerancing and annotation elements.

Standards in the 3D Functional Tolerancing and Annotation workbench are those used and customized in the Drafting workbenches: they are 2D standards, transposed to 3D. As they are defined for the Drafting workbenches, some standard parameters apply only to Drafting applications. However, a great number of parameters apply to both the 3D Functional Tolerancing and Annotation and Drafting products.

  • In a CATProduct document, the default standard defined in the settings is taken into account when the first annotation view is created.
  • In a CATPart document, when a standard is already imbedded in the document, for example when a 2D layout has been created with the 2D Layout for 3D Design product, this standard is reused when the first annotation view is created, otherwise the default standard defined in the settings is taken into account.
     
When you enter the 3D Functional Tolerancing & Annotation workbench and the current CATPart or CATProduct document embeds a standard, the Graphic Properties toolbar settings are reset according to the standard.

Once the first view has been created, modifying the standard file will not affect the document, but the other features standard-based will be affected, for example the 2D layout feature.

For more information on standards and their administration, refer to the User Tasks > Administration Tasks chapter in the Interactive Drafting User's Guide.
