D-27SASIG 3D Annotated Model Standard

Version 1, Dated 06/2008

FOREWORD Technical drawings are information displayed in the form of models or diagrams, which are drawn based on rules and information media. They are often drawn to a set scale and are commonly used to convey the information needed to manufacture a product from product development.

Today’s technical drawings usually include a combination of a 3D model and a 2D drawing. This is a more effective process than the traditional 2D only drawing because digital manufacturing processes today need the 3D model in order to develop tooling and fixtures, perform analysis, build prototypes, etc.

Tomorrow’s technical drawings will incorporate only a complete annotated 3D model containing all of the information necessary to manufacture a part. This will enable more digital manufacturing uses/re-uses of product data, i.e., feeding dimensional information into a CMM machine along with a 3D model. This annotated 3D model, which is used as a single master, is more efficient for product development than two or more technical drawings used today. When the 3D annotated models are converted to a viewing format in a single location, they are much more accessible to the extended enterprise. These viewing tools also enable improved communication and collaboration at a lower cost than with CAD tools.

Existing standards for 2D drawings can only be partially applied to 3D annotated models. This standard, in conjunction with ISO 16792 “Digital Product Definition Data Practices,” defines how to document all the information necessary for all areas (i.e., design, manufacturing, service) in the product creation process.

The method for showing the product characteristics in the 3D model is described in ISO 16792 “Digital Product Definition Data Practices.” However, the method is incomplete as a 3D annotated model standard because it does not address all of the types of information required in a technical drawing. This SASIG 3D Annotated Model Standard will address the information not covered in ISO 16792 for a completely 3D annotated model.

This standard is intended to be tool independent. This standard will be used for further development of CAD tools.

This standard was developed by the Digital Engineering Visualization Work Group (DEV) of the Strategic Automotive product data Standards Industry Group (SASIG), which began its activities in October 2003.

This SASIG 3D Annotated Model Standard represents the consensus reached by all companies of the global automotive standards organizations (AIAG, JAMA/JAPIA, GALIA, VDA, Odette-Sweden). This standard can also serve as a reference to non-automotive industries as the issues are very similar.

Special Implementation Considerations and Disclaimers

• The SASIG DEV Work Group is making every possible effort to harmonize this SASIG 3D Annotated Model Standard with existing related Global standards.

• This SASIG 3D Annotated Model Standard closely follows the ISO 16792 standard. • Ongoing efforts are in place to harmonize ISO 16792 and the SASIG 3D Annotated

Model Standard with other ISO publications. • The SASIG DEV Work Group has identified ‘discrepancies’ within different ISO

standards.

INTRODUCTION

Scope This SASIG 3D Annotated Model Standard is the global automotive industry standard for creating 3D annotated models. Though developed by the automotive industry, this standard is applicable to all industries. The primary emphasis of this standard is to ensure that all of the information required to completely define a product is captured within the product definition data set, e.g., model geometry, 3D annotations, management data, etc… as defined in ISO 16792.

This document can be used for vehicle and manufacturing design documentation.

This document is an enabler for the complete replacement of 2D drawings by 3D annotated models. For additional details and use cases, see the SASIG DEV Guideline Document (D-21).

Legal or regulatory issues pertaining to 3D annotated models are not within the scope of this document.

Terms and Definitions For the purpose of this standard, the following terms and definitions apply. Only terms not defined in ISO 16792 are listed below. Please reference ISO 16792 for additional terms and definitions.

Note: When the term ‘feature’ is used in this standard in reference to a model or drawing, it is referring to the digital representation of the feature.

area

Expressing the size of a region of space by the surfaces.

CAD System

An authoring tool for creating and modifying 3D annotated models. Note: If the viewer is used to create the 3D annotations and / or markups, then the viewer would become an authoring tool as well.

coordinate, global

Large-area coordinate system that is defined for the target space, or the coordinate values represented by this coordinate system.

coordinate, local

Localized coordinate system that is defined relatively for global coordinates, or the coordinate values represented by this coordinate system.

create history

The history (records) of CAD modeling.

design change

Change of product shape, a product characteristic, management data.

design change content

Detail of design changes.

The “design change” means the change of product shape, a product characteristic, management data.

design change history

The history (records) of design changes.

design change number

Number(s) displayed on the model to identify the design change.

dimensional parameter

Input variables to change a product shape.

dimensional parameters, relational expression for

A numerical equation relating a dimensional parameter with a value to set a dimensional parameter.



- 14 -


dimensional parameters, table for

model, 3D model, three-dimensional model

Model geometry displaying a three dimensional shape. They can be classified into solid models, surface models, and wire frame models. When an annotation to display product characteristics is added to a 3D model, this is also called a "3D model."

model, CAM

Models for processing.

model, solid

Model geometry displaying a 3Dimensional shape so that the space occupied by this shape is clearly specified.

model, surface

Model geometry displaying a 3Dimensional shape using surfaces.

model, wire frame

tabular

Annotation supplementing the content of the model in the form of a table. For example, a table containing multiple pieces of information necessary for processing, measuring, or testing.

texture mapping

Used in order to express the feel of a material of a 3D model.

title block, title panel

A table provided as part of a model for the entry of items required for model management and product management information related to the contents of the model such as part number, part name, company name, etc. in a single group.

viewers

1 PRODUCT DEFINITION DATA (3D ANNOTATED MODELS)

1.1 Purpose This chapter defines a 3D annotated model.

1.2 Requirements The 3D annotated model contains the model, product characteristics, and management data (see Table 1.2-1 and Figure 1.2-1.) Figure 1.2-1 shows the information configuration of 3D annotated models. Figure 1.2-2 shows an example of a 3D annotated model.

The 3D annotated model may be contained in multiple files that are collectively called a product definition data set per ISO 16792.

Table 1.2-1 Examples of information needed to define a product

Group Information necessary for definition of a product.

Model 3D shape, model coordinate system.

Product Characteristics

Dimensions with tolerances, notes, user-defined coordinate systems, and supplemental geometry.

Management Data Follow ISO 16792 sec. 3.18 for management data (i.e., part name, part number, quantity used, approval signature/date, design change history, destination, and configuration).

2 MANAGEMENT DATA

2.1 Purpose This chapter outlines the methods for annotating management data.

2.2 General Requirements a) Refer to ISO 16792, sec. 5.4 “Management data” for a general requirement for annotating

management data.

b) For requirements regarding notes and special notations, see ISO 16792 sec. 8.2.

c) Management data can be created in the CAD system and/or other electronic formats. Whenever possible, the data should not be duplicated (see Figure 2.2-1 and Figure 2.2-2.)

d) The location of all data required to completely define a part needs to be identified from within all data files.

e) Management data location and structure are determined by company policy.

f) Title block, notes, item block, and other management data should be arranged to avoid overlapping.

g) In general, management data will apply to the entire product. Exceptions would include multiple material specifications, finishes, etc. When these exceptions exist, the features that they apply to must also be identified within the 3D model.
