Welcome to the Functional Tolerancing and Annotation User's Guide!
This guide is intended for users who need to become quickly familiar with the product.
This overview provides the following information:

Functional Tolerancing and Annotation in a Nutshell

Functional Tolerancing and Annotation lets you easily define and manage 3D tolerance specifications and annotations directly on 3D parts or products.
The intuitive interface of the product provides an ideal solution for new application customers in small and medium-size industries, looking to reduce reliance on 2D drawings, and increase the use of 3D as the master representation for driving from design to manufacturing engineering process.
Annotations in Functional Tolerancing and Annotation can be extracted, using the annotation plane concept in the Generative Drafting product.
Finally, the 3D annotations can be reviewed using ENOVIA - DMU Dimensioning and Tolerancing Review 1 product (DT1) or DELMIA - DMU Dimensioning and Tolerancing Review 2 product (MTR), which offers comprehensive tools for interpretation of annotations and tolerances on specific areas of the design or across the complete digital mockup.
This manual is intended for users who need to specify tolerancing annotations on 3D parts or on 3D products. It assists designers in assigning the correct tolerances on the selected surfaces by:
  • Selecting the surfaces to be toleranced.

  • Choosing among the available options, the tolerance types, the modifiers, etc. The system offers a choice of options which are consistent with the selected surfaces.

  • Entering the tolerance value. The tolerance annotation is then created and displayed around the 3D geometry. It is also located and oriented in an annotation plane, using a standardized model (usual standards: ISO, ASME / ANSI).

As a consequence, designers do not need to wonder whether the tolerancing syntax is correct, because this syntax is directly elaborated with regard to the chosen tolerancing standards (ISO, ASME / ANSI).
Designers are ensured that their tolerancing schema is consistent with the part geometry. They do not need to be tolerancing experts, having in mind all the complex standardized tolerancing rules. Moreover, the tolerancing specifications will remain consistent whatever the geometrical modifications are.
See Reference Information for further detail.
Functional Tolerancing and Annotation allows you to work with the cache system, in other words in Visualization Mode. Annotations can be recorded or not with the related cgr document using this mode. From the cgr document, annotations are displayed and they can be queried and filtered. Of course, when you are editing an annotation the related document is automatically switched to Design Mode.
Note that three workbenches are available depending on whether you are working on:
  • a part (Functional Tolerancing and Annotation workbench)
  • a product (Product Functional Tolerancing and Annotation workbench)
  • a process (Process Tolerancing and Annotation workbench).
This guide is intended for users of all 3 workbenches, as the functionalities available are exactly the same from one workbench to another. However, note that the scenarios provided in this guide use parts (CATPart documents) as examples. 

Before Reading this Guide

Before reading this guide, you should be familiar with basic Version 5 concepts such as document windows, standard and view toolbars. Therefore, we recommend that you read the Infrastructure User's Guide that describes generic capabilities common to all Version 5 products. It also describes the general layout of V5 and the interoperability between workbenches.
You may also like to read the following complementary product guides, for which the appropriate license is required:
  • Product Structure
  • Part Design
  • Generative Drafting

Getting the Most Out of this Guide

To get the most out of this guide, we suggest that you start reading and performing the step-by-step Getting Started tutorial.
Once you have finished, you should move on to the User Tasks section, which deals with handling all the product functions.
The Workbench Description section, which describes the Functional Tolerancing and Annotation workbench, and the Customizing section, which explains how to set up the options, will also certainly prove useful.
Navigating in the Split View mode is recommended. This mode offers a framed layout allowing direct access from the table of contents to the information.

Accessing Sample Documents

To perform the scenarios, sample documents are provided all along this documentation. For more information about this, refer to Accessing Sample Documents in the Infrastructure User's Guide.
