NBYIT Solution(www.nbyit.com) a Leading Technology firm and 3D modeling Service in particular, all the stronger part of our lives. It is difficult to imagine that any modern wherever it was encountered starting from the preparation of high quality visual material for a magazine or create a cartoon sverhtehnologichny to production equipment.
In my opinion the modeling can be divided into two branches:
A) 3D modeling Service, which is used in the practice designers, animators and game developers.
B) Engineering 3D modeling Service used by engineers and designers around the world to create real things and mechanisms.
Of course, the model made in such packages like 3D Max, ZBrush, Cinema 4D and others subjected to quality and rendering professional impression of its realism. They create a model that is almost indistinguishable from the real objects. At the heart of these programs is modeling using polygons, the use of which can significantly ease the "weight" models, reducing the load on the computer resources. This is especially true for developers of modern games, which is saturated with a large number of game scenes modeled objects and textures, involving the player in the "real" game world.
But engineering 3D modeling Service - is another matter. Models made in software packages for the "techies» (SolidWorks, Autodesk Inventor, Compass 3d, Pro / Engeneer et al.), Can not only see how it will look the projected product or assembly, but also involve these models later in production, allowing to organize full "life cycle" of the product, from idea to finished parts and mechanisms.
Basically they are using parametric modeling and mathematically accurate descriptions of curves and surfaces (NURBS modeling).
Pros parametric solid modeling are obvious: First, the basis of the creation of the 3d model is a kind of hierarchy of successive actions, forming a so-called "build tree," ie. it is possible to return to a definite step backwards to any desired change parameters or the size of a part or assembly without destroying it; in the case of polygonal modeling - all will have to correct, or at all, to build anew.
Secondly, modern packages of engineering modeling and 3d are constantly improving their already built-in plug-ins to create a high-quality presentation of scenes and movies, such as SolidWorks Photoview 360. Of course they are not as powerful as renderings for design programs, but to demonstrate the operation of certain their mechanisms is sufficient. In addition, there are already a large number of third-party renderers, allowing to easily import models made in CAD systems, for example KeyShot.
Thirdly, working in engineering CAD system can be immediately subjected to the projected product versatile physical, mechanical, thermal, and many other studies.
This allows you to immediately, on the basis of the data for calculating optimize their model by different criteria, which are placed in front of the designer. For example, to select an optimal beam profiles section starting from loads acting on it, determine the geometry and the heat sink area with minimum weight required for a predetermined amount of exhaust heat. In general, the range of tasks, where applicable calculations CAD huge.
Fourth, designing and creating a product from the assembly of parts may also be animated, and the process of its work, identifying shortcomings and optimizing design. This option we have when designing
