AutoCAD 21.0 Download
Although AutoCAD was not originally intended as a commercial product, it was commercialized almost immediately by its development team. In November 1982, Autodesk produced the first version of AutoCAD on a microcomputer, the MSX personal computer (PC).
AutoCAD is the world's second-best-selling CAD application and is sold in more than 130 countries around the world.
This article focuses on AutoCAD's computer-aided drafting (CAD) features and overview of its key elements. For information on AutoCAD's related software, visit Autodesk.com.
What is AutoCAD?
AutoCAD is a software application for designing, drawing, and drafting 3D and 2D models. In addition to the 3D features, it also includes other drawing tools, and it can be used to create technical drawings, specifications, design documentation, and more.
The following graphic shows a sample AutoCAD drawing:
A drawing of a single block in a steel shaft. The three horizontal lines on the block represent the three axis that intersect at the center of the block.
Two views of the same drawing. The top view (with the blue cylinder in the foreground) shows the block's overall geometry. The bottom view (with the gray cylinder in the foreground) shows the block's surface (or cross-section) geometry.
What makes AutoCAD a specialized CAD application?
While the other popular CAD programs listed here work on a similar model, their applications are designed for a range of tasks. AutoCAD, on the other hand, is designed for drafting and designing a very specific type of technical drawing: the detailed 3D drawing of a mechanical or architectural object. The following sections examine the specific features and functions of AutoCAD, including:
Drafting and designing a block or line drawing
Creating a parametric drawing
Using measure, mark, and draw tools
Creating 3D geometry and parametric modeling
Using camera tools
Using direct and reverse engineering tools
Using datums, coordinates, and layers
Creating 2D and 3D drawings
Modeling parametric geometry
Using advanced drawing functions
Using imported and native AutoCAD objects
Drafting and designing a block or line drawing
The heart of AutoCAD is its software for drafting and designing 3D drawings. These 3D drawings are

Do programs like gzip, m4, and Make for which every command takes at least 1 second to run really make a difference?
For example, if I were to make a personal backup and compress it, using the commands
gzip -1z "$1"
and
m4 -mu "$1"
Will that make a difference? I have not tried, but I assume that if all of those commands are called in a one-second window, they will all run in the same amount of time. Is this true?
A:
It depends on the version of m4 you're using. GNU m4 is very fast (one of the fastest implementations, in fact). I believe the current m4 supports multi-threading, which helps.
Another aspect is the CPU speed of the host you're executing the m4 on. If your CPU is slow, it'll have a lot of trouble to do multiple
