CoCreate’s Free 3D: OneSpace Modeling Personal Edition

CoCreate Software, Inc., a leading provider of 3rd generation PLM software applications for high-tech electronics and machinery, today introduced the world’s first free Dynamic Modeling based 3D CAD software, CoCreate OneSpace Modeling Personal Edition (PE).

OneSpace Modeling PE is a freely available download offering all the power of CoCreate’s enterprise OneSpace Modeling 3D CAD system for assemblies up to 60 parts.

This version enables any engineer, designer or student to experience the extraordinary power of a Dynamic Modeling based approach to 3D product development, the cornerstone of the CoCreate OneSpace Suite. And even the most casual user or hobbyist will be immediately productive through a full set of self-paced tutorials, quickstart projects, online help and user forums.

Key benefits available in this release include:

  • Easily import and completely edit standard 2D and 3D file formats to experience the unparalleled interoperability of the CoCreate platform, where geometry is always king.
  • Radically transform existing designs from nearly any source to satisfy new market requirements, while shaving weeks to months off development timelines.
  • Respond to unexpected or changing requirements more easily, more frequently and much later in the development process through a history-free approach.
  • Discover an easier to learn and use 3D CAD system that combines 2D’s ease of use with the inherent benefits and power of 3D. Moving from 2D to 3D has never been this easy.
  • 100% faster product development through empowered design teams, lean product development methodologies and the CoCreate platform.

  • There are two approaches to 3D product development. OneSpace Modeling PE brings Dynamic Modeling to engineers and designers worldwide, giving them choice and liberation from the overhead and complexity of history-based modeling.

    “Customers tell us that CoCreate gives them extreme speed, flexibility and responsiveness to change in 3D product development. These traits come from a Dynamic Modeling based approach,” said William M. Gascoigne, CoCreate CEO. “OneSpace Modeling PE ends the industry’s status quo, and lets the 3D CAD users see that there is a fork in the road for 3D product development tools.”

    For companies and individuals wanting more, the CoCreate platform is easy to grow into. All 2D drawings and 3D models created within OneSpace Modeling PE can be unlocked and carried over to CoCreate’s full production environment. Subscription licensing (rent versus own) and a 15 minute, 6 button click deployment model for CoCreate’s powerful data management are just a few of the examples of how easy it is to adopt the CoCreate platform. More importantly, CoCreate’s Dynamic Modeling based interoperability strengths means there is no switching cost in moving to the CoCreate platform.

    This is a time limited opportunity until March 31st to secure your free copy of OneSpace Modeling PE – so act now! To register and download your personal copy:

    Commentary By Jeffrey Rowe, Editor

    OK, I’ll admit up front here, I was skeptical about the “free” software thing. My skepticism was quickly dashed, though, after I talked to some CoCreate folks about the offer and its implications.

    Although CoCreate isn’t the first or only MCAD vendor to offer free software, this activity is part of a bigger plan whereby the company hopes to more aggressively compete in this cutthroat market. This offer is actually an important part of the company’s commitment to this market. Other aspects that are currently in play include the fact that it is in the process of expanding its sales channel by increasing its number of resellers, and a number of flexible ownership options are available, including an option to rent the software by the week. With all that is going on, the company seems to be backing the effort across the board 100%, and that’s a good thing.

    CoCreate’s OneSpace Modeling philosophy works on the same major tenet of lean practices of any type – keep things that are essential and eliminate those that are not. Probably the biggest thing that set OneSpace Modeling apart from the competition is Dynamic Modeling based on a history-free design approach. While not for everybody, this approach can provide some surprising benefits. So, what are some of the pros and cons of history-based versus history-free modeling?

    Today, the majority of mechanical CAD products are parametric, history-based applications. CoCreate’s OneSpace Modeling, however, is one of the exceptions. OneSpace Modeling’s history-free architecture can make it easier to make design changes to 3D models without the need to know how a design was originally created. CoCreate calls this “dynamic modeling,” and is a unique method for designing parts and assemblies. Some users may not like the absence of the history at first, especially those who have experience and a comfort level with parametric, history-based systems. However, I think that just as many users will appreciate the shorter learning curve and the
    likely faster changes that can be made to a design without having to deal with its design history and associated graphical model feature tree.

    Parameters can unintentionally apply the brakes where the speed of design changes can be critical. For example, in parametric models, each entity, such as a line or an arc, has parameters associated with it. These parameters control the various geometric properties of the entity, such as the width and height of a rectangle or the radius of a fillet. They also control the locations of these entities within a part model.

    Parameters can (usually) be changed to create a desired part for design optimization or maintaining original design intent (although that’s another potential point of debate). History-based parametric modelers create and maintain a record of how a part model is built. When parameters in a model are changed and it is regenerated, the CAD application repeats the operations from its history, using the new parameters, to create a new part model. An advantage for this type of modeling is that you can perform “what if” scenarios and test various sizes of parts to determine which is the “best” part for a given purpose by simply adjusting a part model’s
    parameters and regenerating the part.

    So, while parametric history-based modeling can be a powerful design method, it can also complicate things and make models created using this method difficult or impossible to work with, especially late in the design process, based on inherent dependencies. This is exactly what OneSpace Modeling plays off of for collaborative design teams who need to perform design changes without having to concern themselves with constraints, parametrics, and history-based feature trees.

    As I said earlier, beyond OneSpace Modeling, today, the majority of mechanical CAD products are parametric, history-based applications. There are, however, some notable exceptions – IronCAD and KeyCreator. CoCreate’s OneSpace Modeling is a 3D CAD tool based on a dynamic history-free architecture that can make it easier to make design changes to 3D models with no need to know how a design was originally created. CoCreate calls this “intuitive modeling,” and is a unique method for designing parts and assemblies, but may put off some users at first, especially those who have experience and a comfort level with parametric, history-based systems. That said, though,
    parameters aren’t always what they’re cracked up to be.

    Some parametric modelers also allow constraint equations to be added to models. These can be used to construct relationships between parameters. If several parameters always require the same value, or a certain parameter depends on the values of several others, this is the best way to ensure that these relationships are always correct. This ability, however, can also lead to problems, especially if changes are made to parts that are heavily parameter-dependent.

    CoCreate is doing a lot of things to increase its presence in the MCAD market, and the company seems to be going about it in a methodical and calculated way. Will they appeal to everybody? Well, no, but the way they are going about it says that they are in for the long haul.

    I’m looking forward to downloading CoCreate’s OneSpace Modeling PE myself and checking out what it can do. I’ll report back what I discover.

    Review Article

      I want to provide clarification regarding the CoCreate platform and what it means to have a Dynamic Modeling based approach.

      There are two approaches to 3D product development: history-based and Dynamic Modeling based (or history-free). Each approach is different and each has its own benefits and applications for a company. Which is best for an organization is based upon the company, their product, and their product's lifecycle.
      Sometimes the differences between the two, and what it means to be Dynamic Modeling based, is best shown rather than described. In support of this, we created an on-demand webcast that presents the benefits of our approach followed by a product demonstration highlighting the product’s applications and strengths.
      On-demand webcast: http://www.cocreate.com/rd/dd
      The benefits we enable are supported through a long list of customer successes across the high-tech electronics and machinery industries. These stories span the small to mid-size business up to the corporate enterprise. Some feature companies that at first tried a history-based approach and then switched to CoCreate’s platform because of the characteristics of their product development process.
      Success stories: http://www.cocreate.com/success_stories.cfm
      We separate the discussion of history and parametrics. CoCreate also offers parametric capabilities within its product. Parametric relationships are important for some types of product development environments and we recognize that. Rather than having a fully constrained model, CoCreate lets you add them as needed.
      The primary difference between these two approaches is in the geometry creation and modification process. And that comes from either being history-based or Dynamic Modeling based.
      I hope that the above resources help clarify and support CoCreate’s position within the CAD and PLM industry.

      Thanks for the Article Jeff, might be an interesting tool for people that have to work on designs that they did not develop, or if they don't own a Hybrid Modeler like 'all_trades_jack' mentions...
      But for people that design their own products from scratch, there is no doubt in my mind that they would want a history based modeler. Of course that should be one that keeps all previously chosen parameters accessible to future definition and change. If hybrid dynamic modeling was used to modify an existing design the change will hopefully become a parametric history based 'change-feature' until somebody goes and exports to a simple geometric solids description file format and effectively looses the history information again. But lets be aware that having to describe a geometry will almost certainly take much more storage space than to only have to store the object tree of the historic creation and modification of 'features'. And don't even imagine having to modify applied patterns repeated many times, or changing your mind about an earlier applied feature! So if you want to be able to reuse your designs, create parametric variations and exploratively try out things; don't flush your investment! Keep your History!

      The article explains what history-based (parametric) modeling is, but does not explain what CoCreate's "Dynamic Modeling" is. So, the claims that Dynamic Modeling are superior are just that: claims. No substance.
      Also, the buttons in the page to go to the next page make no sense. One seems to jump to some other random article, rather than a continuation of the existing article.

      As a user who moved from Solidworks to CoCreate due to a job change, here's a hands on perspective. It honestly took a day of training for me to 'get' what CoCreate means by history free or dynamic modeling. But now there is no chance I'm going back to history based modeling. On almost every project before using CoCreate, I *hated* changing requirements, especially those we did not plan for (most of them). Inevitably, 'just one more change' and the model would break and I'd start from scratch rather than try to fix it. That always meant working later at night than planned. But with CoCreate OSDM, they've managed to put a ton of intelligence into thier modeler and somehow elimated the history tree (I still don't get how, but it is amazing). OneSpace Designer Modeling is a parametic modeler, it's just a history free one, which is great. It's the best of both worlds. And I can even open up files from all kinds of other tools and edit them as if I deisnged them myself (absolutely amazing). As for Taylor (All Trades Jack) above who is a Product Manager for UGS/NX, better take a closer look at OSDM before ripping on it. Your statements are like saying that Windows is antiquated based on looking back at Windows version 3.1. I watched the video and you should too.

      It's always interesting to watch companies that have been left behind in the dust technologically market their antiquated solution as "revolutionary." Non-parametric modeling used to be the *only* way to work. While I can see the advantage in a hybrid system (like NX from UGS) that allows both parametric modeling and direct manipulation of the geometry, The CoCreate claim that parametrics are completely useless is just plain silly. "Retro" is kinda cool for living room furniture, but certainly less desirable in a mainstream design tool.
