CAD – Popularly Beneficial

�ۿ۴�ý — Sat, 15 Oct 2011 05:39:59 +0000

Computer Aided Design, popularly known as CAD Design, refers to the use of computer technology for the purpose of designing and drafting in various fields. It is also known as Computer Aided Design and Drafting (CADD). CAD is extensively used in many fields, as a substitute for manual technical and engineering drawings. It is widely applicable in industries such as architecture, aerospace, multimedia, automotive, prosthetics, etc. The major benefit of Computer Aided Designs over the manual drawings is that the designers can complete the designs much faster. As a result, their productivity increases and more works can be completed in less time. The firms benefit much from this as they can finish more work with less labour.

The designs done using are of high quality and fewer errors are likely to occur when compared to manual drawing. If errors occur, they can easily be corrected and the design can be modified using the computer technology. Moreover, the design can be zoomed in and out for obtaining distinct views of the parts or components of the drawn object. With the CAD software, the designer can scale the image as per the needs and guidelines. In case the designer wants to add additional properties to an object, the Computer Aided Design software provides the option to create such custom properties.

The computer hard drive saves the data drafted with CAD. Hence, the backup is automatically created, which reduces the risk of losing the data. Furthermore, an easy conversion of 2D drawings into 3D is also possible with the use of CAD technology.

3D Rendering – Where Art Meets Design

�ۿ۴�ý — Mon, 14 Mar 2011 11:21:40 +0000

Computer Aided Design has come a long way since the early days of 2D CAD drafting tools. Today, a massive amount of information can be conveyed by 3D rendering of images, using professional software to give an uncanny degree of photorealism. One example is the 3D Max Render platform; a widely used mechanical design tool developed by Autodesk Media.

The 3D render process combines 3D modelling with photo realistic rendering. Using industry software, a physical object is created as a 3D wire-frame model on screen. This is then converted into a photorealistic image using techniques like texture mapping. In CAD animation, good quality 3D rendering can be almost indistinguishable from film footage. 3D Max Rendering has been used for video games, commercial TV productions and movies such as Avatar and 2012, as well as engineering and architectural design.

It would take several volumes to explain the full process of 3D photorealistic rendering. Basically, the image is generated from either a single wire-frame model, or a group of models (called a scene file). The more complex the scene file, the more difficult the process becomes, as attention must be paid to geometry, shading, texture, lighting and view points (as in traditional art). Otherwise, the effects can be unrealistic and, in the case of CAD animation, cartoonish.

We at �ۿ۴�ý Technologies employ a skilled team of 3D rendering experts, who using the latest 3D Max Render software can make your own design sketches an exciting reality.

Developments in CAD Animation

�ۿ۴�ý — Thu, 06 Jan 2011 15:08:39 +0000

The old-fashioned method of meticulously drawing and then photographing images to create a moving picture came to an end at the close of the 20th century. Then, animators began scanning or drawing their images onto computers, using CAD drawing software. CAD animation opened up enormous possibilities, not only in movie making, but in mechanical design as well. CAD drafting was already well known, but now engineers could see how mobile designs, such as cars and machinery, would actually look in performance. Computational fluid dynamics and fatigue analysis became possible too. The latest development has been 2D to 3D conversion of images and 3D CAD animation. It seems now that every new animated movie sells itself on the strength of its 3D animation, and again the implications on mechanical design have been enormous. Not only can you create the illusion of movement within your model, but you can also look at it from all angles and, again, utilize CFD. There are a number of different types of CAD animation, some of which are used in engineering design. Morph target animation: Images are stored as a series of vertex positions, moving each vertex to a new position, frame by frame. Used for animation of, for example, fabric and facial expressions. Again, widely used in advertising. Skeletal animation: Used to animate vertebrate movement, it is also widely used in mechanical design. In this case the ‘skeleton’ is a mechanical one. We at �ۿ۴�ý technologies offer CAD animation as one of our reverse engineering services; a field in which it has proven invaluable.
