Although AutoCAD has made significant advances in its approach to engineering and drafting since its early years, the capabilities and features of AutoCAD are constantly expanding and changing. Like all software programs, AutoCAD has bugs and other potential problems.

This guidebook provides essential AutoCAD tips and references to aid you in using the program properly.

What is AutoCAD?

AutoCAD is a 2D- and 3D-based, commercial CAD software application for drafting, design, and engineering that runs on Windows, macOS, and Linux platforms. It was developed by Autodesk and is available as desktop, mobile, and web-based applications. It is used by thousands of engineers, architects, and drafting professionals worldwide. AutoCAD has won numerous awards for its software since its debut, including a “Product of the Year” award in 2005, 2006, and 2012. It is also compatible with most CAD programs from other manufacturers.

AutoCAD was introduced to the market in December 1982 as AutoDraft by the London-based company BEP-International as a desktop application running on microcomputers with internal graphics controllers. The first version of AutoDraft was released to business customers, but the technology behind AutoDraft was also used for consumer and student CAD programs.

In 1986, Autodesk acquired BEP-International and merged it with its previously established computer-aided design (CAD) division. Autodesk released AutoCAD, first on microcomputers, and later on mainframe computers and minicomputers. The first time AutoCAD was introduced to the broader market, it was an initial success.

Although Autodesk may have coined the term “AutoCAD,” it is not the only software application capable of performing the functions that AutoCAD does. It is not “Auto” anything because other applications perform some of the functions that AutoCAD performs. Many CAD programs can perform basic 2D and 3D drafting, for example. CAD programs can also perform various engineering functions. AutoCAD is unique, however, because of its features, capabilities, and the strong community of users.

What is AutoCAD Used For?

AutoCAD is used by thousands of engineers, architects, and drafting professionals worldwide. Some of the jobs that AutoCAD users perform include:

Drafting 2D and 3D architectural and construction drawings

Drawing bills of materials and assembly

Adoption
After being introduced in 1999, it was broadly adopted. By 2005 the number of AutoCAD users had grown to 14 million.

SketchUp
In 2007 Autodesk acquired SketchUp, a free 3D modeling tool. SketchUp is based on the free Vectorworks platform. Autodesk launched SketchUp Pro, a commercial version of SketchUp, at the 2008 meeting of the BIM.SG conference in Singapore. At the same time, Autodesk released AutoCAD 2008 SP1, to allow the export of models made with SketchUp, in addition to the ability to import them. A similar product was released for Architectural Foundation (ArchRF) for Civil 3D. In October 2010, Autodesk updated AutoCAD to version 2011. AutoCAD 2010 and the new LT systems are also known as AutoCAD Pro, and as AutoCAD Architecture and AutoCAD Civil 3D, respectively. AutoCAD LT is an LT for 3D buildings, maps and surfaces. The AutoCAD LT system is also available for free. In August 2012, Autodesk released AutoCAD LT 2012.

CAD key products

AutoCAD

AutoCAD is used for drawing architectural, construction, interior, mechanical and engineering drawings. In addition to its AutoCAD Architecture application, it is also used to create many third-party applications. In the architecture profession, it is the primary 3D design application.

AutoCAD can be used for either drafting or drafting-and-annotating. In drafting-and-annotating mode, as opposed to drafting mode, the user manually traces over the desired path by using the pen.

Additionally, the AutoCAD application is also used to create architectural design models. By using the appropriate Add-on software, AutoCAD can be used to produce floor plans, elevations, sections, and 3D models.

Among the 3D architectural applications are ArchRF, AutoCAD Architecture and AutoCAD Civil 3D. ArchRF is a set of AutoCAD LT add-on products for the design and analysis of architectural buildings. AutoCAD Architecture is a set of add-on products for architectural design in AutoCAD LT. AutoCAD Civil 3D is a set of add-on products for civil engineering design in AutoCAD LT.

AutoCAD and its add-on products include a number of AutoCAD modules:

Q:

How to replace a portion of a string in an array element in C?

This is a function that prints out an array, but I am unsure how to replace only part of the string. I am trying to replace a certain portion of a string in a particular array element.
void printArray(char *c)
{
int i;
printf(“%s
“, c);
for (i = 0; c[i]!= NULL; i++)
printf(“%c
“, c[i]);
}

Input:
abc
Output:
abc
a
b
c
d

Input:
cdcdcd
Output:
cdcdcd
c
d
d
d

Input:
abc123
Output:
abc123
a
b
c
123

Input:
abc123abc123
Output:
abc123abc123
a
b
c
123abc123

This is what I tried so far:
if(c[i] == NULL)
printf(“%c
“, c[i]);
else
{
c[i] = (c[i] – ‘a’) – (‘0’ -‘a’);
}

It’s not working. The output is always a c.

A:

Try this:
void printArray(char *c)
{
int i;
printf(“%s
“, c);
for (i = 0; c[i
