Design Agility a Key Pain Point
6/28/2012

Engineers who responded to the PTC survey said modifying imported designs is painful, such as this example, of placing the white bolts properly based on the recognition of the pattern.   (Source: PTC)

Compatibility issues

Is there any progress being made toward compatability in CAD, Beth? I remember when there were about 12 different word processing programs that weren't compatible. That changed with time as compatibility improved and one program became the standard (except in the law profession). Any chance of this happening with CAD?

There is definitely progress and PTC's release of this study and its implications that it will continue to work on solving one of its customers' biggest pain points is a sign of that. Most CAD vendors today recognize that it is a heterogeneous world out there and with today's design initiatives involving suppliers, outsource partners, etc., there is no way everyone is going to be working with the same CAD tool, let alone same version of the same CAD tool. Siemens PLM Software has done a lot of work around open standards with JT Open and most CAD vendors consistently talk about their ability to work with other CAD formats whenever they do a new release. It's not perfect yet, but it's definitely moving there. A far cry from years past, no doubt.

Yes, Siemens PLM seems to be concentrating on making the managment of design easier. A lot of their recent releases seem to be focused specifically on addressing ways to handle design technology efficiently and effectively.

Excellent selection of subject matter on CAD challenges and incompatibilities that still persist today.  This article addresses the 'white elephant' in the room that CAD vendors are typically reluctant to talk about.  I'm glad that PTC is willing to openly discuss solutions for this potentially large productivity gain.

It is a fact that many companies work in a heterogeneous CAD environment and have to edit and work with 3D solid models that are not 100% compatible with each other.  Yes, 3D models can be imported between CAD systems using IGES, STP, etc. formats.   However, in the majority of these cases, the complete model associativity is lost and the imported design can't be completely edited or modified.  Then if a design change is needed, delays typically occur because this imported model can't be truly modified.

I look forward to reading more about PTC and other CAD suppliers approach to this issue.

Virtual Reality (VR) headsets are getting ready to explode onto the market and it appears all the heavy tech companies are trying to out-develop one another with better features than their competition. Fledgling start-up Vrvana has joined the fray.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
While every company might have their own solution for PLM, Aras Innovator 10 intends to make PLM easier for all company sizes through its customization. The program is also not resource intensive, which allows it to be appropriated for any use. Some have even linked it to the Raspberry Pi.
solidThinking updated its Inspire program with a multitude of features to expedite the conception and prototype process. The latest version lets users blend design with engineering and manufacturing constraints to produce the cheapest, most efficient design before production.
