In the second quarter 2009, all CAD developers will be able to license the software toolkit, which facilitates development of the applications with functionalities of variational direct modeling in the shortest possible time. Endeavoring to make the new technology immediately available to the CAD users, LEDAS is releasing a free add-on application for the popular 3D design system Google SketchUp in October 2008; which will gradually — from version to version — open all opportunities of the new technology. LEDAS has also announced its plans to develop similar applications for other well-known 3D modeling platforms.

«We announce our plans to welcome co-operation with companies and individual CAD developers that can already share their opinions on the prospects of the new technology and participate in financing our project», said David Levin, CEO, LEDAS Ltd. «Unlike some companies that announce new technologies but do not licence them to developers, we are open for co-operation with all CAD vendors without exception».

The end-user paradigm of direct (also called explicit or dynamic) modeling in CAD involves direct manipulation with the boundary elements of a solid model (faces, edges, vertices). It considerably simplifies creating and editing 3D forms, making it easy-to-use by the amateur users and enhancing designers? efficiency. As a practical alternative to history-based modeling, direct modeling in its pure form has a significant shortcoming: it completely ignores the design intent, established in the model by its creator.

«We offer the approach based on the concept of variational modeling combined with direct model editing», explains Dmitry Ushakov, Director, Product Management and Marketing, LEDAS Ltd. «Using geometric and dimensional constraints which are automatically generated according to the topology and geometry of a boundary model (BRep), according to the features, or are directly specified by the users, our solution enables smart parametric modification — preserving the logic, directly or indirectly put in the original model».

A geometric model with constraints is calculated by a special software component — LGS 3D variational geometric solver, which solves the systems with thousands of simultaneous constraints in the on-line-mode. The solver can be successfully integrated with all geometric modeling kernels available on the market and serves as the basis for implementing the new technology of variational direct modeling.

I have experience in using Catia V5 so I am familiar with the way to contrain a model whether it s 2D or 3D.

In Rhinoworks I would like to coincide endpoints of 2 lines. I can't seem to be able to do that. Is there a way to solve this ?
I d also like to see a good 2D tutorial as an example on your website. I ve seen some neat videos of 2D animations but would like to see how the constraints were done.
All in all it s an excellent plug in and will definitely add it to my rhino plug-ins list

Kind regards,

Alexandre

I want to make sure the license will work for me. For Rhino and Rhinocam I use my main notebook at home, but I have a pc in my home shop attached to a cnc mill where I also use them. At my day job I own a desktop and I use them there too. One thing they all have in common is that I am the only user on any of these machines and they are all used one at a time, never simultaneously. This is not a problem for rhino or rhinocam but I want to make sure this type of use is supported for rhinoworks. And who knows, when those slick windows 8 notepad type machines are available I might want it there too.

FYI I am an experienced Rhino user.

It would be most excellent if the 'Constraint Value' field would accept 'Constraint Names'; for example the Value for 'Distance4' would be able to = 'Distance3', thus tying Distances 4 & 3 together...

A more explicit version of the inbuilt Design Intent feature.

Great plugin-in; please keep up the excellent work!

In the attached file, every time I try to make a full rotation of the given model, it shows me the error dialogue. I can't seem to figure out the reason why.
Could you please explain which components to select as the first object, second object, and what to choose with the axis option?

Thank you very much in advance,

Is there a 64 bit build of RhinoDirect available?

Best regards,.

Reading about DirectX11, which seems to promise support for physics based calcs on the GPU.

It strikes me physics calcs are like kinematics, which are like the constraints solving calcs.

Will the LEDAS solver be able to leverage the GPU / multicore thru something like DirectX11 or OpenCL or CUDA?


Cheers
