The .dwg File Format
Autodesk created .dwg in 1982 for use in its first version of AutoCAD software.1 DWG is a trademark owned by Autodesk, as is the name "AutoCad".2
Note:The use of DWG and AutoCad (both trademarks of AutoDesk) on this website in is soley for the purposes of recognizing the CAD standard set by AutoDesk and does not imply the endorsement of AutoDesk or AutoDesk's ownership for the material on this web site.
DWG2 Format Compatible CAD Libraries
Cad libraries are organized collections of dwg and supporting files. The primary advantage of using a CAD library is that it is more efficient and effective. By making it unnecessary to begin the drawing from scratch, the CAD library saves time and money. A slightly less obvious benefit is that these collections allow designers, such as engineers, architects etc., to quickly implement routine or standard items in their design. This allows them to focus creative energy on new items specific to their unique project.
CAD Blocks
CAD blocks are named groups of objects, sometimes called CAD Symbols, that act as a single object in your drawing. CAD blocks are used to create repeated content such as drawing symbols, common components, and standard details. Blocks help you save time, maintain consistency, and reduce file size by reusing and sharing content rather than re-drawing it every time you need it.4
Block libraries are essentially DWG Libraries for blocks. The terms "Block Library" and "Symbol Library" basically mean the same thing.
About our Libraries
The free cad library consists over 300 sample dwg files. (If you are looking specifically for free cad blocks, the free cad blocks are in a directory called Symbols--DWG.)
Our main library consists of over 9200 dwg files (CAD blocks, Cad Details etc.) for the fields of Archetechture, Engineering and Construction. The files (divided into the major categories of commercial and residential) are organized hierachically into over 150 categories so you can drill down to what you need quickly.
Our original library contains 5,500 2D .dwg format CAD construction details for both residential and commercial projects. All the elements in the drawings are composed of lines only (there are no hatches or embedded dimensions) and the drawings are fully editable so that you can customize them as if you had drawn them yourself. These highly detailed drawings cover 141 categories. They also are organized hierarchically for easy drill down.
The bonus material library contains more than 100,000+ useful and ready to use dwg cad drawing files in 71 categories.
These libraries are available for Instant Download or on DVD.

CAD Programs (Generic)
CAD stands for "Computer Aided Design". Generically, it refers to the process of using computers, rather than the traditional drafting board, to create and maintain technical drawings.

Computer Aided Desgin Software
By now "Computer Aided" design is the rule rather than the exception. It's important to remember that it's not always faster or more productive to create designs with a computer rather than with pencil and paper. The advantage comes when it's time to modfiy the design and reuse standard components. Desiging "the old way" often required that even small changes to a design would result in new drawing be created from scratch, requiring many expensive hours of rework. To make matters even more inefficent, much of each type of drawing was spent creating (from scratch) standard components or parts.
This new type of software, which was very expensive by today's standards, was well worth the price due to the great reduction in time for rework and for the creation of standard components, details and symbols.
Libraries of files, such as the ones we provide, are the reason Computer Aided Design software became so prevalent.
AutoCAD by Autodesk, is one of the earliest and arguably the most famous of all Computer Aided Design programs. They literally set the standard for CAD file formats. Because our libraries are compatible with AutoCAD 2000, they will work with nearly any standard CAD program.3
Analogies and Metaphors
Video Examples
When CAD Software was first introduced, the raw expense of computer power meant that only 2D drawings were possible. And, since floor plans and similar designs were always 2D, nobody saw this as unusual. Today, of course, 3D designs are common. What's important to remember, however, is that 2D drawings are foundational (no pun intended) to the creation of 3D drawings. One of the newer pieces of 3D design software, which is targeted at less experienced designers is SketchUp. As the name implies, by design, it lacks the depth of more sophisticated tools. However, it's fairly straight forward to use 2D DWG files in SketchUp as the following video shows.
Using CAD well is a learned skill that takes a lot of practice. As such, it is common for companies to provide free entry level versions of their programs to students and beginners. The following video is an example of such a program.
