Overview

Welcome to the 3D Functional Tolerancing & Annotation User's Guide.

This guide is intended for users who need to become quickly familiar with the product.

3D Functional Tolerancing & Annotation in a Nutshell

Functional Tolerancing & Annotation application lets you easily define and manage 3D tolerance specifications and annotations directly on 3D Parts or between them.

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 & Annotation can be extracted, using the annotation plane concept in the Generative Drafting product.

This manual is intended for users who need to specify tolerancing annotations on 3D Parts. 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).

    Note that geometrical tolerances require some settings to be defined in addition for their numerical display, see Tolerances settings.

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 3D shape 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.

Before Reading this Guide

Before reading this guide, you should be familiar with basic Version 6 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 6 products. It also describes the general layout of Version 6 and the interoperability between workbenches.

You may also like to read the following complementary product guides, for which the appropriate license is required:

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 user tasks, which cover all product functionalities.

The Interface Description section, which describes the commands that are specific to 3D Functional Tolerancing & Annotation, and the Customizing section, which explains how to customize settings, will also certainly prove useful.
