GrabCAD Announces Integration with PTC Creo and Workbench Summer 2014 Release

GrabCAD Workbench is a cloud-based file management platform that makes it easier for users to manage and share CAD files.

It appears the folks at GrabCAD have been quite busy. The Cambridge-based startup is making two significant announcements today: the integration of its Workbench cloud-based file management platform with PTC Creo CAD software and the release of Workbench Summer 2014. Since PTC Live Global was just held this week in Boston, we’ll start with that one. The integration of Workbench... Read More

PTC Releases Creo Elements/Direct v19.0

PTC Creo Elements/Direct 19 now offers support for multi-CAD environments, via Unite technology

Another announcement made at this year’s PTC Live Global event was the release of PTC Creo Elements/Direct 19.0, direct modeling software that now includes productivity enhancements in modeling, drafting, collaboration and data management. As mentioned in the Creo 3.0 blog, the company also unveiled new technology it’s calling Unite technology that better supports multi-CAD... Read More

Creo 3.0 Announced at PTC Live Global

The new release of Creo 3.0 will enable customers to work and consolidate data from any CAD source.

Amid the excitement of users, partners, analysts and members of the press–along with hundreds of Boston-based employees, PTC announces the release of Creo 3.0. Among the most impressive of its enhancements and feature upgrades is what PTC has dubbed Unite Technology. Designed to help its customers overcome the struggles of dealing with CAD data in multiple formats, Unite... Read More

Luxion Releases KeyShot 5 Rendering Software

New features in KeyShot rendering software enable engineers to make their workflow more efficient and take their visual assets to the next level.

Rendering software is increasingly being put to use by design engineers to create downstream product collateral used to support, maintain and sell products–often before the product even exists in physical form. Rendered 3D models are also created and used early in the design process to speed the process of obtaining customer or management approval. Rendering vendors are working... Read More

Debating the Most Efficient Way to Go from Concept to Documentation

This concept design for Yamaha was created by a Alberto Agnari. It included concept boards, sketches and traditional and digital renderings.

The conceptual phase of design is the only one within the product development window that must be inherently fluid, and in a sense, should be done in a leisurely manner. What, you ask? The word “leisure” is probably not used often when it comes to designing products, right? OK, let me explain. In order to fully evaluate a suitable number of potential design concepts,... Read More

The Role of Associativity in Direct Modeling

Design associativity is not exclusive to history-based 3D modeling approaches. Image courtesy of PTC.

When designers and engineers think about design associativity, they often think about history-based 3D modeling systems. CAD software that deploys a history-based approach to modeling requires engineers to anticipate and define feature constraints, relations and dependencies, which ensures that any design change will update all related downstream geometry. That’s design associativity.... Read More

Preparing Models for Simulation: Which 3D Modeling Paradigm is Best?


Simulation technology has its origins in the labs of universities and specialists groups within the aeronautics and automotive industries. Today, however, simulation software has moved from research labs into mainstream product design and engineers and designers are increasingly using simulation tools to guide their design choices. How simulation tools are used today As designs... Read More

The Challenges of Model Editing in the Multi-CAD World

Nearly half of all product development companies continue to struggle with how best deal with CAD data originating in other CAD systems. Image courtesy of Siemens PLM.

In today’s world, most engineers and designers are now accustomed to dealing with CAD data created in other CAD systems. With design collaboration with suppliers, partners, and customers being a key component of today’s product design, the use of multiple CAD systems has become the norm. As a result, companies must become proficient at working with CAD data in multiple... Read More

The failed promise of parametric CAD, final chapter: A viable solution

Model reuse

What is the failed promise of parametric CAD? In short, model reuse. It’s a lot more difficult than it ought to be, for a variety of reasons. Several months back, I wrote a series of articles discussing those reasons, as well as some of the solutions that have come up over the years.  What was missing from the series was a final chapter; a detailed description of what could... Read More

The failed promise of parametric CAD part 5: A resilient modeling strategy


The model brittleness problem inherent with parametric feature-based modeling is a really big deal. And it’s something, honestly, that I don’t have a great answer for. I’ve even asked a few power users who I know, and their answers seemed to involve a bit of hand-waving, and a reference to having lots of experience. While best practices are a potentially good step... Read More
