Rosemary Astheimer, continuing lecturer in Purdue University’s Department of Computer Graphics Technology, has been certified as a Technologist Geometric Dimensioning and Tolerancing Professional by the American Society of Mechanical Engineers (ASME). She is the only Purdue-affiliated professional on the list of certificate holders.
The certification indicates Astheimer has demonstrated competencies in understanding Geometric Dimensioning and Tolerancing (GD&T) as it applies to engineering drawings and related documentation.
As an instructor in the virtual product integration program in the Department Computer Graphics Technology at Purdue Astheimer works with the GD&T concept regularly. She developed and teaches the model-based definition certificate program, which is targeted at working professionals to inform them on an emerging industry technique whereby information traditionally captured on 2D drawings is now being captured in 3D CAD models. This technique allows for wider dissemination of product data through an increasingly digital product lifecycle, including automated manufacturing and metrology systems.
"Rosemary’s certification is a great acknowledgement of her expertise in the field,” said Nathan Hartman, professor and director of the Product Lifecycle Management Center at Purdue. “In her courses on model-based definition and communication, she is able to help companies leverage the precision and sophistication afforded by digital methods to make better business decisions and better support their end customers.
