is used mainly for creating architectural designs or blueprints. Some of the available software in the market, allow users to mark different components of a design with different color variations. Some of the most advanced CAD drafting software available can support a million color variations.
CAD drafting software programs use different types of color numbering systems such as RGB (red, green, blue) and HSL (hue-saturation-luminance).

The availability of different CAD drafting software has helped in eliminating the need for manual design drafting. Complex can now be drawn and designed easily.

Since there is a lot of confusion about CAD files, I thought some of this would be helpful.

Almost every CAD program has their own binary CAD format.

And most CAD formats have many versions! For example:

AutoCAD 12 cannot read AutoCAD 14 DWG any more than Word 97 can read Office XP docs.

I’ve opened the gathering - http://en.wikipedia.org/wiki/Category:CAD_file_formats while looking for formats and found some.

Here is the excerpt:

There are some "more or less generic formats" used for exchange. Here are some:
DXF (many versions over the years)
IGES (Current version 5.3 ?)
STEP (*.stp - be careful of this one - several versions called "application

Autodesk was defeated in the first round of this battle in Seattle US District Court, May 21 2008:

Read Vernor versus Autodesk

Judgement Announcement

Interestingly, Autodesk is also resorting to more and more desperate measures to attack the Open Design Alliance:

The issues around this ruling are complex and a final district ruling is not due until June. But it could serve as an important benchmark for similarly licensed software sold by other companies. Such decisions can ultimately challenge the
