Solid Model Tolerancing
(Based on ASME Y14.41)

Understand the fundamental definitions, concepts, and methods from the new ASME Y14.41-2003 Standard.

Exclusively from ETI, the Solid Model Tolerancing Workshop will help you to understand the benefits of a math-based product development process. You’ll learn:
• How to use solid models to eliminate 2D drawings
• How to apply GD&T to solid models
• The new symbols and conventions used in Y14.41
• The changes required in GD&T when tolerancing solid models
• The annotated model method and the drawing plus model method from Y14.41
• Six factors to determine which method is best for your organization
• The issues and challenges encountered when adopting the tolerancing of solid models
• How to use the flexibility in Y14.41 for a practical transition to a math-based development process
• Six organizational issues that must be addressed when implementing solid models to replace drawings

Course Developer: Alex Krulikowski, Past Chairman of the ASME Y14.41 Committee on Solid Model Tolerancing

Our Solid Model Tolerancing course was developed by an expert on the subject: ETI founder, Alex Krulikowski is the former Chairman of the Y14.41 Committee. The new standard advances the capabilities of Y14.5, Dimensioning and Tolerancing, the widely used standard pertaining to 2D engineering drawings. Y14.41 defines the exceptions and additional requirements to existing ASME standards for using product definition data or drawings in 3D digital format.

About the Course
The Y14.41 Standard establishes requirements for preparing, organizing and interpreting 3D digital product images.The Solid Model Tolerancing course is not based on any single CAD system or product development process. It covers concepts and standards that can be applied with a number of CAD systems.

Who Should Attend
This course intended for designers, engineers, and managers who are considering implementation of a math-based product development process.

Skill Level Needed
Attendees must have a basic understanding of Y14.5 Dimensioning and Tolerancing practices.
