Varatech Engineering Consultants, Inc.

SigmundPro, a powerful tolerance analysis software for ProEngineer developed by Varatech, enables engineers to evaluate, optimize and validate assembly build quality, relative to piece part tolerance and assembly process variation. Fully integrated within Pro/Engineer, this value-added tool can be used early in the development phase before design solidification and hard tooling procurement. SigmundPro prevents costly tweaking delays at ramp-up as well as long-term variation problems. SigmundPro is integrated with Pro|Engineer 200i2, 2001, and Wildfire.

SigmundPro can predict the quality of a Pro/Engineer assembly based upon predetermined tolerance values or determine the component tolerances required to meet a given assembly build objective. SigmundPro even includes a powerful utility, which automatically optimizes all tolerances in a given model. SigmundPro's powerful utilities and easy to use menu-driven modeling capabilities greatly reduce modeling time and effort, and its succinct reporting module provides all relevant information in four easy-to-interpret reports. SigmundPro optimizes design and assembly process, add precision where needed and eliminates overly costly designs.
