Description: We are a non-profit organization dedicated to the free exchange of information related to the use of SOLIDWORKS. NMSUG provides a forum in which participants may assist each other in furthering their knowledge and abilities. Our roster includes seasoned users, rookies, college students, engineers and designers, machine operators, SOLIDWORKS professionals, and hobbyists. Network, share ideas, learn about new features and witness WOW! moments. Whether you are a business or an individual, we welcome your involvement. If you would like to learn more please visit the Contact Us page for information on who the current officers are and send them an email.

Geometric Dimensioning and Tolerancing is a language for defining and communicating the geometric properties of mechanical parts (e.g. ASME Y14.5). The language can be applied to both 2D drawings and 3D models, and is a significant improvement over "plus and minus" tolerances. Like any language though, getting started can be difficult. This presentation will help to lay a foundation for further study as well as provide examples of what "good GD&T" looks like.

The mantra of the NMSUG is: "Life is about Relationships. Relationships are about Communication. SOLIDWORKS is a Communication tool." Join us for this special event to learn some of the grammar in the language of SOLIDWORKS.


Wednesday February 21st, NMSUG Meeting Agenda:

  • 5:30 - 6:00 Arrive, Get Some Food, Meet Someone New
  • 6:00 - 7:00 Specifying GD&T for Mechanical Part Definition (Part 1)
    • Bob Goodwin (Sandia)
  • 7:00 - 7:15 Break
  • 7:15 - 8:15 Specifying GD&T for Mechanical Part Definition (Part 2)
  • 8:15 - 8:30 Wrap Up / Prizes / Giveaways



Specifying GD&T for Mechanical Part Definition

The intent of the presentation is to provide an overview of the application of the geometric controls most commonly used for machined-part definition (which includes most of the controls available) without going into the fundamental nuts & bolts of a basic GD&T class. Basic concepts will be presented as they apply to the particular geometric control being addressed. The most emphasis will be on the True Position control and its variations, from positioning holes, positioning surfaces or median planes, to composite position control. The Profilecontrol, which is the next most useful control, and then the application of the Form, Orientation, and Runout controls will also be described. The philosophy of functional dimensioning & tolerancing, and datum selection, as the basis for repeatable verification of manufactured parts will also be emphasized.



Bob Goodwin currently works in the Mechanical Design & Drafting Services organization at Sandia National Laboratories. He was recruited into the machine shop apprenticeship program, as an inspector, at Sandia in 2003 from the TVI (now CNM) Machine Tool Technology Program. After a year and a half he transferred to the Sandia Design Services organization, and also completed the Design Drafting Engineering Technology Program at CNM – though his best practical drafting training was through 2 ½ years of on-the-board classes in high school. Prior to working at Sandia, Bob worked as a Journeyman Electrician for 4 years, and then as a general and electrical contractor for 12 more. Bob has been doing mechanical design and drafting work at Sandia since 2004. He currently holds a GD&T Professional certification at the Senior level from ASME.
