A few weeks ago we were in Los Angeles attending SOLIDWORKS World 2017. As usual, it was an overwhelming whirlwind of people, sights, sounds, and information while it was taking place, but has come into better focus now that some time has transpired for letting all of it sink in and make sense. One of the things I wanted to especially sort out was SOLIDWORKS’ take on model-based definition (MBD), where it stands today, and where it might be headed in the future
The last day of SOLIDWORKS World 2017 I sat down with Oboe Wu, SOLIDWORKS MBD Product Manager, and we discussed several aspects of MBD. Our discussion on SOLIDWORKS MBD centered around the creation and consumption of MBD data (that are tied to customers’ workflows), and the fact that MBD is transitioning from the “why implement” phase to the “how to implement” phase.
In the video below, SOLIDWORKS MBD Product Manager, Oboe Wu, discusses how to eliminate conversion of 3D data to 2D documents and fully leverage 3D design data throughout an organization and partners to reduce redundant tasks. He explains MBD from SOLIDWORKS’ point of view.
I read a lot of books, mostly non-fiction and technical in both hardcopy and digital formats. Although I get through most of them, there are some I don’t even try to finish, and a few become favorites that I keep for future reading and reference. I recently read a book entitled Re-Use Your CAD: The ModelCHECK Handbook by Rosemary Astheimer. When I saw Handbook in the title, I thought it would be another dry reference book, but I was pleasantly surprised that it was much more than that — it’s a good learning and reference resource.
The book’s author, Rosemary L. Astheimer, is an application engineer for Action Engineering, as well as a Continuing Lecturer for the Polytechnic Institute at Purdue University. She received her BS in Mechanical Engineering from the University of Massachusetts in Amherst and her Masters of Software Engineering from Brandeis University. Before joining the faculty in 2014, Ms. Astheimer spent over 15 years working in the CAD software industry. She began her career in software support, transitioned into a pre-sales application engineer focusing on business development of new products and was most recently a product manager.
Remember a long time ago when the so-called “paperless office” was just around the corner. Well, we’ve all turned a lot of corners over the years waiting for the nirvana that still seems to be “just around the corner.”
Of course, strides have been made for a way to communicate design engineering information in a paperless manner, but one of the most promising developments has been model-based definition (MBD) and model-based engineering/enterprise (MBE).
We spoke with Aaron Kelly, SOLIDWORKS’ Vice President, User Experience & Product Portfolio Management about many things regarding the SOLIDWORKS 2015 portfolio launch, including a brand new offering called SOLIDWORKS MBD. It is designed to help improve communication between design and manufacturing teams by enabling them to communicate product and manufacturing information (PMI) in 3D. The intent here is to use Model Based Definition and to no longer use 2D drawings to define products.
Over the course of a year I read a lot of books — technical, non-fiction, hardcopy, and digital. Most of them I get through, although there are some I don’t even try to finish, and a few become favorites and are kept for future reading on my bookshelf. I just finished a book entitled Re-Use Your CAD: The Model-Based Handbook by Jennifer Herron. When I saw Handbook in the title, I thought it would be just a dry reference book, but I was pleasantly surprised that it was much more than that — it’s a good learning resource.
First, a little about the author and model-based engineering/model-based design (MBE/MBD).
I’ve known Jennifer for several years as we’ve crossed paths at software conferences. She is the owner of Action Engineering, a company that specializes in the promotion, process development, and standardization of 3D CAD MBE and MBD. She is an expert in multiple CAD packages, which she uses along with her practical design experience to hone standards and processes that optimize the ROI of all CAD systems.
She also offers model-based documentation education seminars, MIL-STD-31000A schema and modeling best practice training, as well as planning consulting services for Model-Based Engineering implementation. Keep in mind as you read the book that based on her experience, she is a stickler for standards, such as ISO, but you realize that’s probably a good thing.
Her company is a consulting firm that transitions government organizations and companies to effectively and efficiently implement Model Based Engineering. With a specialty in training organizations to document and tailor their business practices to be compatible with CAD, PDM and PLM software tools, Action advises companies in: CAD modeling standards and best practice, designer modeling efficiency, CAD configuration management, MBE training, team collaboration and CAD interoperability.
The concept(s) of MBE/MBD have received a lot of attention in the past few years because this approach handles product development using a digital master model, and not just necessarily CAD. All downstream activities can be derived from the master model to develop a product. The MBE/MBD approach replaces puzzling documents and can minimize the need for physical prototypes before an optimized design has been developed. In other words, engineers and designers can simulate and iterate as much as necessary to refine a model while also meeting requirements and adhering to design constraints.
Now on to the book . . .
Reuse Your CAD Handbook
The book is structured in a logical manner for those both new and experienced with MBE/MBD. Throughout, it stresses the importance of standardizing, centralizing, documenting, and reusing a CAD database. It’s written in a CAD-agnostic manner, so its principles can be applied in any CAD environment, regardless of vendor.
A sampling of some of the topics covered in the book include:
Explanation of the philosophy of designing products using CAD model-based life-cycles
Implementation guide to model-based commercial (ASME Y14.41), government (MIL-STD-31000A) and company standards
Model-based benefits, risks, and action plans
3D MBD model organizational schema
3D MBD model protocols to satisfy the schema CAD agnostically
Part and assembly modeling best practice
Mass property implementation methods
3D model Data Exchange (DEX) methods
MBE support infrastructure requirements
Product data management (PDM) fundamentals and requirements
A good friend of ours at MCADCafe, Jennifer Herron, owner of Action Engineering, a company that specializes in the promotion, process development and standardization of 3D CAD Model-Based Design (MBD) just released a new video on reusing CAD parts.
In the video, Action Engineering calls a catalog part, a part or subassembly used more than once in a family of products. It may be a bearing, motor, bolt or washer. In a 3D model-based environment a catalog part model should be assembled into your organization’s native CAD assembly models and includes accurate geometry (as specified from the supplier), attributes (Material, Color), metadata (Part Number, Description, Supplier) and annotations (Dimensions and GD&T). A single catalog part model is the single authority for each catalog item used in your organization.
