The American Society of Mechanical Engineers (ASME International) has announced a new technical standard, ASME Y14.41-2003, which establishes requirements for preparing, organising and interpreting 3-dimensional digital product images.
ASME Y14.41-2003, Digital Product Definition Data Practices, which represents an extension of the popular Y14.5 standard for 2-dimensional drawings, reflects the growing need for a uniform method of documenting the data created in today’s computer-aided design (CAD) environments.
Beneficiaries of Y14.41 include the departments of the US government and their subcontractors in industry, which for several years have sought a manageable system for preparing and interpreting CAD product data.
The standard also provides a guide for CAD software developers working on improved modelling and annotation practices for the engineering community. ASME Y14.41 sets forth the requirements for tolerances, dimensional data, and other annotations.
ASME Y14.41 advances the capabilities of Y14.5, Dimensioning and Tolerancing, the widely used standard pertaining to 2-D engineering drawings. Y14.41 defines the exceptions as well as additional requirements to existing ASME standards for using product definition data or drawings in 3D digital format.
ASME Y14.41-2003, Digital Product Definition Data Practices is available from ASME at (800) 843-2763. Online purchasing is available at the <a href=’http://www.asme.org/catalog’>ASME Digital Store</a>. The price of the standard is $95.
The ASME subcommittee that developed the new standard includes technical representatives from General Motors, Boeing, Caterpillar, Rolls-Royce, and Raytheon, among other leading industrial firms. The US Department of Defense and EDS PLM Solutions were also members of the subcommittee.
