Cheetah SolverBreakthrough in Geometric Constraint Modeling

Computer-Aided Design (CAD)

• No matter what you want to do: to construct a mechanism, to build a house, or just to rearrange furniture in your room – you need a plan• Technical drawing or drafting is the act of composing plans that

visually communicate how some parts are to be constructed• The traditional drafting procedure is to place a piece of paper on a

smooth surface and to draw something by pencil using some set of manual tools, such as T-square, Ruler, Stencil etc.• Nowadays, the technics of a drafting task have been significantly

automated and accelerated through the use of CAD


Computer-Aided Design

• Computer-aided design is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design• Nowadays CAD systems began to provide much more capability than

just an ability to replace manual drafting with electronic drafting. Namely:• automated generation of the Bill of Materials (BOM);• auto layout in integrated circuits;• interference checking;• performing engineering calculations;• and many other tasks.


Coordinate-Driven Approach

• The original 2D CAD was coordinate-driven. It means that, while operator is creating points and lines in 2D sketch, the software record the coordinates of all and points in the drawing• The problem with this approach arise when you need to modify the

design – even a small changes usually require to update manually the coordinates of numerous points influenced by this small change• Parametric approach allows to think in terms of dimensions (linear

dimensions and angles) and geometrical constraints instead of coordinates


Parametric Approach

• Using parametrics you draw geometric entities (points, lines, curves), set dimensions between different entities, and set geometric constraints (like parallel, perpendicular, tangent etc.)• The software itself writes equations from these constraints. In these

equations coordinates of points are the unknowns and dimensions are the parameters of equations, that define the solution• With parametric approach when you change some dimension you

don’t need to modify sketch manually, the system automatically recalculates coordinates of all points and regenerates the model


User’s Pain in Parametric CAD

• The idea of parametric approach is quite simple and very attractive, but the resulting system of equations can be very large and very complicated. For complex geometric models it may contain many thousands of equations with millions of variables• All modern parametric CAD applications are not able to process

complicated geometric constrained models. Very often their behavior is unstable even for models containing a small number of entities• Even, if such a solver is capable to resolve some intricate model, users

often have to wait long time to obtain a result


Cheetah Solver of Cloud Invent

• Today’s solver engines, were developed decades ago. They were not changing in years. They are using slow archaic mathematical methods and working in one thread mode even on multi-core CPU• Cheetah solver can work with geometrical models that contain

hundreds times more geometric entities and resolve them thousands times faster than you can do with any competitor solver• Our solver works in parallel threads so it’s performance can be scaled

infinitely by increasing number of cores in your system. It can work on multi-core CPUs, many-core GPUs, and intel Xeon Phi cards


AutoCAD Plugin

• The first implementation of our solver is the plugin for AutoCAD 2015+• We chose to start from AutoCAD because it is one of the most popular

CAD-system, but it has very poor parametric functionality. The other reason for us was that AutoCAD has very developer-friendly .Net API• Our plugin embeds into AutoCAD and intercepts all handlings to solver.

So, you have the same user experience as with the built-in solver• When you start using Cheetah Solver plugin for AutoCAD, it does not

mean that you can’t use built-in solver. You can easily switch back and forth from one solver to another by pushing a single button

Our Roadmap

• The first version of Cheetah Solver Plugin covers only 2D parametric functionality of AutoCAD• The next version (end of 2015) will provide for AutoCAD full-featured 3D parametric functionality• In parallel we are working on implementation of our solver for other

CAD-systems (Autodesk Inventor, SolidWorks of Dassault, Solid Edge of Siemens etc.) and for different hardware platforms (NVidia CUDA, Xeon Phi, Amazon Cloud Cluster, Windows Azure etc.)


Our Market• For AutoCAD plugin our potential customers are all AutoCAD users• Autodesk claims to have 12 million registered users. About half of them

(6 million) are AutoCAD users• We can create similar plugins for the other CADs. So, our potential

customers are all engineers and designers who use parametric CAD• Autodesk holds about 1/3 of the CAD market. If we will add Siemens

(SolidEdge and NX), Dassault (SolidWorks and CATIA), and PTC (Creo Parametric), then we will cover about 80% of all CAD users• The size of the whole CAD-market is about $10 B per year. • Our Cheetah Solver plugins can add to this market the new segment of

the size minimum $100 M per year


Our Market• Now we are launching beta-testing of Cheetah plugin for AutoCAD and

we are planning to launch commercial version next year (3rd quarter). • Our business model: • Subscription: $9/month or $99/year for access to any available plugin and for

any available hardware-specific solver (CPU, GPU, cloud)• Purchasing: $99 for base plugin and $99 for each hardware-specific solver

• Pessimistic estimation is $1 M customers (from more then 30 million CAD users), so it will be about $100 M per year• But we estimate not less than 10 million customers. Therefore, it will

be about $1 B per year


Investments• Now our team is small and we can concentrate just on one way – we

chose AutoCAD as a CAD platform, and CPUs and NVidia GPUs as hardware platforms• We are receiving requests for possibility to use our technology with

other CADs, other hardware (such as ATI GPUs, AMD Mantle, Itanium processors etc.) and on cloud (Amazon cloud, Windows Azure, etc.)• We can satisfy this requests, but to do this we need the growth• In order to grow we need more investments• If we will get $500,000 we will be able to do 3D parametric core and

2D plugins for SolidWorks and Solid Edge simultaneously
