Welcome to the DMU Dimensioning & Tolerance Review User's Guide!
This guide is intended for users who need to become quickly familiar with the product.

This overview provides the following information:

DMU Dimensioning & Tolerance Review in a Nutshell

Everybody in the company must have a common understanding of tolerance information. Similarly the company must have the same understanding of the tolerance information used by its own customers and suppliers.
This understanding view is critical to avoid any loss of information or any misunderstandings in supplier/customer relationships.

International tolerancing standards define the "official view" and a system ensuring that what is created is consistent with this official view.

DMU Dimensioning & Tolerance Review allows you visualization, querying and filtering of mechanical dimensions and tolerances in the context of the collaborative design review environment of the full digital mockup. DMU Dimensioning & Tolerance Review allows transferring of the dimensioning and tolerancing information to all the users needing access to it, without having to execute the long and tedious 2D drawing generation step (constituting the 3D-only process). Note that this type of 3D-only process is supported by an ASME standard, currently being developed, the ASME Y14.41 on Digital Modeling. This development is also supported within ISO by the TC10 (Technical Committee) . Both of these standards will provide the ability to use either the 2D drawing or the 3D geometrical model in official data exchange.

DMU Dimensioning & Tolerance Review provides assistance to readers using not only the complete bilateral associativity between dimensioning and tolerancing, geometrical elements and features, but also explains the captured semantics.

DMU Dimensioning & Tolerance Review facilitates the full integration of Digital Mockup-centric processes within the global engineering environment of the customer.

Designed for users involved in the technological verification of mockups, it offers dimensioning and tolerancing visualization and navigation capabilities capable of handling digital mockups of all sizes from consumer goods assemblies to very large automotive, aerospace, plant, ships or heavy machinery mockups, while being entirely available on Windows and UNIX.

DMU Dimensioning & Tolerance Review delivers leading-edge technological visualization functions, based on a powerful graphic architecture, and advanced ease of use concepts which have all been already pioneered in the context of CATIA Version 4, and therefore validated by thousands of users in the context of the most advanced and demanding Digital mockup-based processes.

DMU Dimensioning & Tolerance Review allows you to make a review of 2D layout contained in a part and created with the 2D Layout for 3D Design product, from the part or assembly context. This review requires no license of 2D Layout for 3D Design and allows you to:

DMU Dimensioning & Tolerance Review 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.

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:

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.

The Workbench Description section, which describes the DMU Tolerancing Review 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.
