ZWsoft Gets Caught, Apologizes, Pays Settlement, Done. Or Is It?

Wednesday, November 25th, 2015

In its latest legal challenge and triumph, Autodesk as plaintiff and WCAD Software Co., Ltd., ZWCAD Design Co., Ltd., HK ZWCAD Software Ltd., and GLOBAL FORCE DIRECT, LLC. (doing business as ZWCADUSA) (collectively, ZWSoft)  have agreed to settle lawsuits pending in the Hague and the U.S. District Court for the Northern District of California.

In these lawsuits, Autodesk alleged that the AutoCAD source code had been misappropriated and improperly used when developing ZWCAD+. Autodesk had filed suit before the Hague in the Netherlands in February 2014  and in the U.S. District Court for the Northern District of California in March 2014.

Although it initially denied the allegations, ZWSoft’s subsequent internal investigation revealed that an employee had, in fact, improperly used AutoCAD intellectual property when developing ZWCAD+ (another AutoCAD wanna be) and concealed it from ZWSoft’s management team. This sounds something akin to the VW emissions fiasco, and you have to wonder; how could this happen without the knowledge of management?

After the “discovery,” ZWSoft and Autodesk worked to assess and remedy the inappropriate use of Autodesk’s intellectual property. Upon learning these facts and admitting fault, ZWSoft stopped selling ZWCAD+. Customers who purchased ZWCAD+ are eligible for a free replacement version of ZWCAD Classic.

Check out the video below that demonstrates some of the features of ZWCAD+ 2015. Does it look or feel much like AutoCAD? You be the judge.

Forget Just Data Interoperability; Remember Data Obsolescence

Thursday, November 19th, 2015

For as long as I can remember, CAD/CAM/CAE data (I’ll just refer to it as engineering data) has been saddled with a perpetual problematic issue – interoperability. That is, the ability (or inability) of a completely understood load of code to work with other current or future products or systems without any restricted access or utility.

The term, interoperability, was originally defined for information technology or systems engineering services to allow for information exchange. A broader definition takes into account organizational factors that impact system-to-system performance. In other words, the tough task of building coherent services for users when the individual components are technically different and managed by different organizations.

IronCAD Continues To Be Iron Solid

Thursday, November 12th, 2015

When I ask people in the MCAD community to name four or five mechanical CAD products, I get the same answers about 90% of the time. Just based on conversation, I’ve come to regard these four to five products loosely as “first tier,” based solely on mention, not capabilities. This is more of a marketing thing than a functional thing.

When I ask the same people to name another four or five products, the answers vary all over the place. I’ll call this “second tier, “ or mid range, again based on frequency of mention, not capabilities. That’s unfortunate, because a number of products in this tier (or range) have a number of interesting and often unique features and capabilities that can often provide a better user experience. Although I could name several in the so-called second (or mid-range) tier, a product I’ve followed for a long time is IronCAD.

Class Project Turns To Possible Class Action Lawsuit

Thursday, November 5th, 2015

As a first-year Denver Math Fellow (I assist math teachers and tutor in small groups), last week I was give a reprieve from my daily grind of lesson plans and teaching by participating in what my school calls Explore Week. This is a week where I was partnered with a teacher, chose a topic to explore with students, made a video promoting our explore class, and had students sign up to join us.

The topic my teaching partner and I decided on was “Creating Furniture Using Non-Traditional Methods and Materials.” Our course included designing and creating furniture models from cardboard, as well as 3D printing simple models. It was a lot of fun, and as I said, a nice change of pace, not to mention I really felt I was in my comfort zone.

Explore Week was made possible by the efforts of several companies, including:

Software we used for the project:

  • Onshape for 3D design for 3D printing
  • Autodesk 123D Make for converting 3D designs to 2D cardboard designs for laser cutting of cardboard

Hardware we used for the project:

Example 3D printed models were generously provided by:
