CAD technology is used in the design of tools and machinery and in the drafting and design of all types of buildings, from small residential types houses to the largest commercial and industrial structures hospitals and factories.

CAD is mainly used for detailed engineering of 3D models or 2D drawings of physical components, but it is also used throughout the engineering process from conceptual design and layout of products, through strength and dynamic analysis of assemblies to definition of manufacturing methods of components. It can also be used to design objects such as jewelry, furniture, appliances, etc.

Furthermore, many CAD applications now offer advanced rendering and animation capabilities so engineers can better visualize their product designs. CAD has become an especially important technology within the scope of computer-aided technologies , with benefits such as lower product development costs and a greatly shortened design cycle.

CAD enables designers to layout and develop work on screen, print it out and save it for future editing, saving time on their drawings. Computer-aided design is one of the many tools used by engineers and designers and is used in many ways depending on the profession of the user and the type of software in question. CAD is one part of the whole digital product development DPD activity within the product lifecycle management PLM processes, and as such is used together with other tools, which are either integrated modules or stand-alone products, such as:.

CAD is also used for the accurate creation of photo simulations that are often required in the preparation of environmental impact reports, in which computer-aided designs of intended buildings are superimposed into photographs of existing environments to represent what that locale will be like, where the proposed facilities are allowed to be built. Potential blockage of view corridors and shadow studies are also frequently analyzed through the use of CAD.

CAD has been proven to be useful to engineers as well. Using four properties which are history, features, parameterization , and high-level constraints. The construction history can be used to look back into the model's personal features and work on the single area rather than the whole model.

Parameters and constraints can be used to determine the size, shape, and other properties of the different modeling elements. The features in the CAD system can be used for the variety of tools for measurement such as tensile strength, yield strength, electrical, or electromagnetic properties. Also its stress, strain, timing , or how the element gets affected in certain temperatures, etc.

There are several different types of CAD, [10] each requiring the operator to think differently about how to use them and design their virtual components in a different manner for each. There are many producers of the lower-end 2D systems, including a number of free and open-source programs. These provide an approach to the drawing process without all the fuss over scale and placement on the drawing sheet that Open Hardware Power Supply Engine accompanied hand drafting since these can be adjusted as required during the creation of the final draft.

Each line has to be manually inserted into the drawing. The final product has no mass properties associated with it and cannot have features directly added to it, such as holes. The operator approaches these in a similar fashion to the 2D systems, although many 3D systems allow using the wireframe model to make the final engineering drawing views. Basic three-dimensional geometric forms prisms, cylinders, spheres, and so on have solid volumes added or subtracted from them as if assembling or cutting real-world objects.

Two-dimensional projected views can easily be generated from the models. Basic 3D solids don't usually include tools to easily allow motion of components, set limits to their motion, or identify interference between components.

There are two types of 3D solid modeling. Top-end systems offer the capabilities to incorporate more organic, aesthetic, and ergonomic features into designs. Freeform surface modeling is often combined with solids to allow the designer to create products that fit the human form and visual requirements as well as they interface with the machine.

Originally software for CAD systems was developed with computer languages such as Fortran , ALGOL but with the advancement of object-oriented programming methods this has radically changed. Typical modern parametric feature-based modeler and freeform surface systems are built around a number of key C modules with their own APIs. A geometry constraint engine may also be employed to manage the associative relationships between geometry, such as wireframe geometry in a sketch or components in an assembly.

Unexpected capabilities of these associative relationships have led to a new form of prototyping called digital prototyping.

After trying other 3d graphics engines, Ogre3D was by far the best for a good combination of qualities: clean and understandable code, excellent documentation, and a great community. Those three characteristics make me choose it and so far, after almost a year and a half, I have never regretted that decision.

Ogre3D has helped us a lot by speeding up the prototyping phase, testing new techniques for the physics algorithms really quickly, and, as part of my Argo Engine, serving really well as the presentation module. When we looked at Ogre the bar was instantly raised, it easily fulfilled all our criteria and more. The clean, extensible, object oriented architecture was well suited to our needs.

Some open source projects often consist of cryptic, un-maintainable, spaghetti code. The thing I like most about Ogre, is that I do not feel compelled to have a shower every time I touch the code.
