Matching Expectations with Reality for Model Re-Use

Getting from Point A to Point B is rarely a straight line route. Despite our noble expectations and careful planning, we encounter twists, turns, and free falls along the way. It can look and feel like chaos.


With four kids, two guinea pigs, and a dog, my husband and I have started referring to the chaos of our home as entropy.

ENTROPY = lack of order or predictability; gradual decline into disorder

Although at our house, it’s a quick decline. The reality of disorder has unfortunately become our expectation. But this was not always the case! I fondly remember those days when picking up the clutter was a quick task. Let’s just say my expectations have dramatically decreased.

Can you think of times in your professional life when reality fell short of expectations? Perhaps you failed to anticipate the devil lurking in the details?

Rosemary Astheimer, Continuing Lecturer at Purdue Polytechnic Institute, and Jennifer Herron, CEO of Action Engineering, will co-present at the 3D Collaboration and Interoperability Congress (3D CIC) about matching expectations to reality for 3D CAD interoperability and model re-use. 3D CIC will be held in Golden, Colorado on October 25 & 26, 2016.

Presentation Title: Matching Expectations with Reality for Model Re-Use             

Abstract: The curse of 3D CAD interoperability is that the devil is in the details. What we want to happen and what the technology is currently capable of executing are not the same. Much of this has to do with the differences in motivation of how and what CAD systems implement. However, practically, they cannot implement everything, so it is critical that we as users explain what, how, and why we want certain functions. Use cases include SOLIDWORKS, Creo, NX, and CATIA Model-Based Definition (MBD) data creation and data package generation.

About the Presenters:

astheimerRosemary L. Astheimer is a Continuing Lecturer in the Purdue Polytechnic Institute, Purdue University, West Lafayette campus. She received her BS in Mechanical Engineering from the University of Massachusetts in Amherst and her Master of Software Engineering from Brandeis University. In 2016, she earned the ASME Geometric Dimensioning and Tolerancing Professional (GDTP) Certification (Y14.5), Technologist Level.

Before joining Purdue in 2014 as a Visiting Instructor, Ms. Astheimer spent over 15 years working in the CAD industry. She started her career in software support, transitioned to a pre-sales applications engineer focusing on business development of new products in the automotive industry. Ms. Astheimer was most recently a Product Manager at PTC, one of the “big 3” CAD companies, working with aerospace and automotive customers to ensure their data exchange related tasks could be carried out in Creo. Her in-depth experience with major CAD systems, including CATIA V4/V5, NX, and Creo filters into her instruction style at Purdue where she is training both undergraduate and industry professionals in CAD design, MBD, PDM, and PLM.

Outside of work she is a mom, enjoys working out at the gym, watching Formula 1 racing, sewing clothing, and is an active member and league coordinator of the Executive Women’s Golf Association Boston chapter. She is the author of Re-Use Your CAD: The ModelCHECK Handbook, published in 2016.

Jennifer HerronJennifer Herron is the CEO of Action Engineering, a registered Women-Owned Small Business. She serves on the American Society of Mechanical Engineers (ASME) as chair of the ASME Y14.46 Subcommittee on Product Definition for Additive Manufacturing. Additionally, Ms. Herron is a committee member of ASME Y14.47 Digital Product Definition Data: Model Organization Schema Practices, and ASME Y14.37 Composite Part Drawings. Ms. Herron has extensive experience with hardware design, spacecraft flight hardware mechanisms and structures, large deployed radiators, ground robotics, and spacecraft layout. Ms. Herron regularly gives public seminars and consults on model-based topics and leads in-house CAD based trainings. She is an expert in multiple CAD packages, such as Creo, NX, and SOLIDWORKS. In addition to her involvement on many flight satellite systems, Ms. Herron has designed military robot platforms and has a patent for a snake propulsion mechanism. She is the author of Re-Use Your CAD: The Model-Based CAD Handbook, published in 2013.
