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.
AutoCAD History and the Origin of the Icon
AutoCAD was created by Tom Waddell of the Graphic Arts Technical Foundation (GATF), who was hired to design and develop a computer-aided design (CAD) system for the GATF’s Auto-Matic Division. Waddell was recruited to build the new system after previously designing a drafting and CAD software package for an Epson range of dot matrix plotters. His new software was designed to be used with a low-cost Hewlett-Packard HP2000 series of minicomputers.
This first version of AutoCAD, nicknamed A and a half, only contained two command modes: vector/straight and dimension. However, it offered very advanced features for a desktop CAD program at the time of its release. This original version did not have the ability to draw objects, such as a circle, but it could draw lines and move objects around on a page. Many current users incorrectly assume that this first version of AutoCAD did not offer basic tools for users to edit objects.
Prior to the release of AutoCAD, most commercially available CAD software was either for minicomputers (for mainframe use) or written in assembler language, which is difficult for programmers and users to maintain. GATF’s system was based on a RADIC-6 development environment and was written in BASIC, which was the predominant computer language at the time. The RADIC-6 development environment was originally developed for the RC4000, a small minicomputer designed by the U.S. Department of Defense (DoD).
GATF had originally intended to release the AutoCAD system with its original software, but a software update was required before the system would be marketable. The AutoCAD software development company found that the newly created software was similar to the code for the RC4000, and as such, they decided not to rewrite the software, and instead released AutoCAD with the graphics technology that was used for the RC4000. Because of this, AutoCAD was initially developed for a microcomputer with a monochrome display and a low-resolution raster graphics system.
Following a highly publicized court case between Graphic Arts Technical Foundation and AutoCAD manufacturer, in 1985 the AutoCAD 1.0 program was released. AutoCAD 1.0 added a 3D, rather than 2D, environment and was much more like the
A distinguishing feature of AutoCAD for Windows is the ability to run independently of Microsoft Windows operating systems.
The program is usually installed on a Windows workstation, along with the company’s other CAD software. This can be a client workstation or a server. AutoCAD can run on a personal computer or workstation or can run on a centralized server. When installing, a license key is required to allow installation on multiple computers. In addition, a permanent Internet connection is required for use, especially for updates. AutoCAD LT, with a lesser set of features, can run without a permanent Internet connection. AutoCAD Professional licenses do not require a permanent Internet connection.
There are two versions of AutoCAD available, AutoCAD LT and AutoCAD. Each version has a wide array of features. This section is intended to be a reference guide for the most frequently used features.
AutoCAD includes standard drawing features such as text, lines, splines, arcs, circles, ellipses, text boxes, and more. It also includes a number of advanced drawing features.
Arc and arc segment
An arc or arc segment is created by either tracing the outline of an arc with the drawing tools (the arc tool) or drawing the arc with the arc tool.
The arc tool, a small box, is a versatile tool for creating an arc or arc segment. Its functionality is similar to the drawing tools for other objects. (See Drawing tools.) The arc segment tools include:
Arc segments can be either open or closed. The arc segment tool allows the user to:
Set the endpoint and start angle of the arc segment
Set the size of the arc segment, defined by a radius and a step size
Set the direction of the arc segment and the number of degrees from the start angle to the end angle
Arc segments can be overlapped, with a single point of intersection.
A single point can also be added or deleted, causing the arc segment to snap to a line of intersection.
Different types of arcs can be created, such as:
In the Create Arc dialog box, the horizontal and vertical options are available under Arc Type (under the Drawing tab). The End Angle option can be set to:

Modifying the “return” statement in jquery
I’ve got a div with some html in it, and I’m trying to write a function that will take that div as a parameter and return the resulting html.
//These functions are inside a document ready
//This isn’t doing anything
Does anyone know if there is a way for me to make this work?
That’s because you’re calling $() before you use the function. Try this instead:
I’m not sure, but I think you want to do:

Overexpression of FGF-9 or FGF-20 confers a cancer stem cell-like phenotype in colorectal cancer cells.
Colorectal cancer is the third leading cause of cancer deaths in the United States. Intratumoral heterogeneity of colon cancer includes a subpopulation of cells that can self-renew and generate differentiated progeny. These cells are thought to be responsible for initiation, progression, and recurrence of cancer. The majority of research on cancer stem cells (CSCs) has been conducted on acute myeloid leukemia and solid tumors that originate from the breast, prostate, and lung. However, in contrast to these other solid tumors, very little is
