Equipped with the right applications, a computer can be of great help in virtually any domain of activity. When it comes to designing and precision, no other tool is as accurate as a computer. Moreover, specialized applications such as AutoCAD give you the possibility to design nearly anything ranging from art, to complex mechanical parts or even buildings.
Suitable for business environments and experienced users
After a decent amount of time spent installing the application on your system, you are ready to fire it up. Thanks to the office suite like interface, all of its features are cleverly organized in categories. At a first look, it looks easy enough to use, but the abundance of features it comes equipped with leaves room for second thoughts.
Create 2D and 3D objects
You can make use of basic geometrical shapes to define your objects, as well as draw custom ones. Needless to say that you can take advantage of a multitude of tools that aim to enhance precision. A grid can be enabled so that you can easily snap elements, as well as adding anchor points to fully customize shapes.
With a little imagination and patience on your behalf, nearly anything can be achieved. Available tools allow you to create 3D objects from scratch and have them fully enhanced with high-quality textures. A powerful navigation pane is put at your disposal so that you can carefully position the camera to get a clearer view of the area of interest.
Various export possibilities
Similar to a modern web browser, each project is displayed in its own tab. This comes in handy, especially for comparison views. Moreover, layouts and layers also play important roles, as it makes objects handling a little easier.
Sine the application is not the easiest to carry around, requiring a slightly sophisticated machine to properly run, there are several export options put at your disposal so that the projects itself can be moved around.
Aside from the application specific format, you can save as an image file of multiple types, PDF, FBX and a few more. Additionally, it can be sent via email, directly printed out on a sheet of paper, or even sent to a 3D printing service, if available.
To end with
All in all, AutoCAD remains one of the top applications used by professionals to achieve great precision with projects of nearly any type. It encourages usage with incredible offers for student licenses so you get acquainted with its abundance of features early on. A lot can be said about what it can and can't do, but the true surprise lies in discovering it step-by-step.

Features & Benefits

Show You The Way

Often, an architect or engineer, for example, will need to calculate, model, analyze, and visualize a building, road, or rail project. With AutoCAD, the user can begin by creating a drawing. This drawing can be a floor plan, an elevation, an area layout, a wire frame, or an imported drawing.

An example of a floor plan.

From here, the user can annotate the drawing to identify potential problems with the design and create a drawing that shows how the parts of the building will be connected. If the user has an architectural, engineering, or other related design program that is not integrated into AutoCAD, he or she can import the drawing into the other program and save the drawing as a DWG or DXF file.

Model

AutoCAD helps you get the most out of your design. With AutoCAD, you can create 3D models by using the drawing tools and manipulating a 2D image (a sketch, for example) into a 3D, solid model. You can do this by using a variety of commands, including vector drawing and project-based commands. In addition, you can create complex, 2D model that can be subsequently transformed into 3D.

Simplify

When you draw lines and polylines on a screen, you’re creating geometry. These geometric entities can become complicated if you’re having to draw more than one line

History
AutoCAD was originally developed by Peter Meliker and was originally called PolyJetDraw. AutoCAD debuted in 1987. The original AutoCAD was written in LISP and LispWorks.

AutoCAD LT (ADT, LT) was released in 1999. It was developed by Michael Burt who was a LISP developer and the LISP and LispWorks were replaced by Visual LISP in 1992.

AutoCAD LT 2D and 3D were introduced in 2006. It is the first time that a release used the name AutoCAD for a new release. Also, the development version of AutoCAD that was used for the development of AutoCAD LT was called AutoCAD LT 2D and 3D.

In 2013, AutoCAD LT was replaced by AutoCAD WS, which is made up of two components, AutoCAD WS and AutoCAD WS Projector. AutoCAD WS is written in Visual LISP and ObjectARX (C++) programming language. AutoCAD WS Projector supports only the Visual LISP.

Compatibility

Originally, AutoCAD programs worked only with operating systems of that time, such as DOS, OS/2, Windows, and IBM OS/2, and even then only on specific models. In 2007, it gained Microsoft Windows 2000 and XP support, thus operating system compatibility was not a problem anymore, and later programs could run on all computers (desktop and laptop) with these operating systems.

Currently (as of 2017), AutoCAD is available in English, Hungarian, Dutch, Norwegian, Polish, Portuguese, Spanish, Russian, Japanese, Chinese, Korean, German, Czech, Swedish, Danish, French, Italian, and Ukrainian. In addition, there are also AutoCAD LT and AutoCAD WS available for German, Italian, Japanese, Spanish, and Dutch.

AutoCAD has several operating systems support: Microsoft Windows (2000, XP, Vista, 7, 8, 10), Apple Macintosh (Mac OS X), and Linux.

AutoCAD and AutoCAD LT were available on the Windows 95, Windows 98 and Windows NT OS family. Since Windows Vista and later, it can run on the Windows 7 and later OS family. Windows 95 and Windows 98 can run AutoCAD LT and AutoCAD. AutoCAD LT 2D and AutoCAD LT 3D can run on Windows Vista and later.

Q:

How to get upper bounds from (or lower bounds from) the mean and standard deviation?

Is there any formula to get upper bounds from the mean and standard deviation or lower bounds from them?
For example, I have a data set (say a distribution of numbers). The mean of the data is the average of numbers in the data set. Then, is there any way to get a “min value” and a “max value” from the distribution?
I know how to get one from a Gaussian distribution with probability density function $f(x) = \frac{1}{\sqrt{2 \pi}} e^{ -x^2 /2}$. I could get one from $f(x) = \frac{1}{\sqrt{2 \pi}} e^{ -x^2 /2}$ as follows:
\begin{align} u &= \mu + 1.6426 \times \sigma &\text{(based on the 95th percentile)} \\ &= \sqrt{\frac{2}{\pi}} + 1.6426 \times \sqrt{\frac{2}{\pi}} &\\ &= 2.2513 & \end{align}
Then, we can set a range $[0, u]$ and $[u, \infty)$ to search for the data. The data I have is about
