Sigmetrix makes available a new training course for users of its EZtol 1D tolerance stackup analysis software. The EZtol Fundamentals Computer-Based Training Course is part of the company’s comprehensive computer-based training courseware series. 

EZtol is used to assist engineers in understanding the impact of assembly-level requirements on accumulation of part-level dimensional variation and part-to-part assembly variation. 

The new course uses a combination of lecture videos, software demonstrations, detailed exercises, quizzes and a training manual to teach EZtol fundamentals. The company says that upon completion of the course students will be able to analyze multiple 1D stackups on CATIA, NX and SOLIDWORKS models and make design decisions to optimize nominal designs and tolerance assignments. 

The coursework is broken into tasks that students complete at their own pace. 

Topics include: 

  • Brief background reviews on tolerance analysis fundamentals, including a discussion in statistical analysis methods
  • Overview of the interface followed by more in-depth explanations and exercises on the tools provided to analyze stackups
  • Detailed explanation, with examples, of results and associated information provided
  • Reporting and data management

Sigmetrix says engineers and designers using CATIA, NX or SOLIDWORKS who are responsible for assigning tolerances to part dimensions and features will now be able to learn the fundamentals of EZtol at their own pace. The online course uses the same information as their instructor-led course. 

Sigmetrix is a specialist in mechanical variation management, with 25 years of experience in the field. “Whether we are training an individual student or working at the enterprise level to elevate the skills and knowledge of entire teams and departments throughout an organization, we have a solution that ultimately will help yield better products through mechanical variation management,” says James Stoddard, president of Sigmetrix.
