AutoCAD 23.1 [Latest]

AutoCAD has been praised for the robustness of its design and engineering tools, a user-friendly interface, and stable performance. It supports numerous standard and industry-specific 2D and 3D drawing file formats and standard drawing dimensions. AutoCAD and related products provide users with tools for the graphic creation and manipulation of technical drawings, and for the engineering design and planning of physical objects.

Autodesk also publishes a number of related CAD software applications, including AutoCAD Architecture, AutoCAD Mechanical, AutoCAD Electrical, AutoCAD Civil, AutoCAD Plant, AutoCAD Electrical, AutoCAD Land, AutoCAD Electrical, AutoCAD Plant, AutoCAD Land, AutoCAD For Construction, and AutoCAD Raster graphics.


Autodesk, Inc. was incorporated in 1980 and launched the first version of AutoCAD on December 20, 1982. The initial version was a four-person project, with the developers—Andrew Birke, Kevin Michalek, David Lucente, and Ewing Lusk—chosen because of their prior experience with Apple II-based CAD applications, which were in the experimental phase at the time.

The first version of AutoCAD was a limited product—it only supported simple drawing tasks. It consisted of a drawing window on a black background and several panels that could be selected. The application was not designed for multiple simultaneous users or for plotter-based graphics. A later release (AutoCAD Version 2) simplified the user interface and added features such as 3D drawing, toolbars, and a drawing workspace (rectangular area).

In 1987, AutoCAD was released for personal computers using Windows 3.1, and first supported 3D drawing. Starting in 1989, the first Windows-based AutoCAD for personal computers also supported a drawing surface, and renamed the black background to the “Canvas.” AutoCAD 1.1 was first released in 1990 and was a major update to the AutoCAD interface, and was the first version of AutoCAD to support input from plotters (or “input devices”).

Starting with version 2.5, AutoCAD was offered for multiple users on the same PC (multiple windows on the screen), and was designed for use with plotters. In the 1990s, Microsoft released the Windows 3.x and Windows 95 operating systems. AutoCAD continued to be released for Windows, and the PC

External tools and libraries
The Autodesk Exchange Apps store has thousands of third-party tools, libraries and scripts available for use in AutoCAD. Many of these are contributed by customers and partners, and are generally made available for free under an open source licence.

Topology Tools
Autodesk Exchange Apps includes several topology tools. These are listed here, from least to most complex.

Bill of materials (BOM)
The component-level BOM tool allows the user to insert drawings of subassemblies in order to create a database for parts and parts lists. When the final drawing is assembled, the user can access the database and generate a BOM.

Virtual block graphics (VBG)
The VBG tool enables the user to insert schematic diagrams as blocks in a drawing. VBG supports simple schematics as well as a “schematic line-drawing” mode which allows the user to insert line segments in the schematic to make it more complex.

Autodesk Exchange Apps includes a free VBG viewer and VBG editor. In addition to the basic features available in the Viewer and Editor, there is also a VBG Explorer plug-in, which enables easy display of VBG files in the Autodesk Exchange Apps Studio.

Workspace graphics (WGS)
The WGS tool is designed for schematic diagrams of workstation configurations.

The WGS component consists of two parts: a graphic and a CAD file. The WGS component has a small footprint because it is mainly designed to be viewed in a corner of the screen and can be easily resized to the window size.

The WGS component contains three main views: top view, detail view and diagram view. The top view allows the user to view all the components in a drawing. The detail view displays an exploded view of a component. This view has tools for selecting, deleting and creating components. The diagram view is a schematic view of the component.

Workspace diagrams (WSD)
The WSD tool is designed for the generation of workspace diagrams. WSD can generate a block of an assembly, a workspace diagram, or both a block and a workspace diagram.

The other tools include:

The Other category includes Autodesk Exchange Apps tools that do not fall under one of the previous categories.

Some tools in the Exchange Apps are available as stand-alone products that do not require

AutoCAD 23.1 License Key Full

Open the file registry/regedit.exe.
Go to the key HKLM\Software\Tridion\Autocad\xxxxx.
Create a new key with any name and name it “Inactive”.
Insert the value with the given data for the key.
In this example we use the command “0000ff”.

Importing a design

The exported file must be in a format the autocad app recognizes and will import in the normal manner.

Redefine variables in the constructor

When using a namespace, do I need to define variables at the start of the file?
namespace MyNamespace{
class MyClass
int myVar;

Is it required to set myVar at the start of every method, or can I just leave the initialization as above?
I was looking at this example:


C++11 does provide the ability to initialise class members in constructors:
class Foo {
int _bar;
Foo() : _bar(42) {}

But this is not done in your example:
MyClass() : myVar(42) {}

But it is not needed, provided that the constructor does not change myVar at all, because the default constructor initialises members of the class. It is legal to leave the default constructor alone and define a constructor that initialises members. For example:
class Foo {
int _bar;
Foo() : _bar(42) {}

The above class is a strict initialiser. _bar will be initialised to 42, so
