AutoCAD 23.1 Crack+ Free [Win/Mac] (Latest)

The AutoCAD project began in the early 1970s as a tool designed to automate the production of mechanical drawing blocks for the large engineering firms that built the luxury cars of the era, such as BMW and Mercedes Benz.

The project was first codenamed «Inka» or «Fish», a name chosen because of the fish-shaped block pattern that formed the basis of each mechanical drawing block. The project was eventually renamed «AutoCAD» (Automatic CAD) and then commercialized by Autodesk in 1982.

AutoCAD is the largest desktop CAD application available and arguably the most popular CAD application in the world. In 2019, it was the top-selling desktop CAD application, and the third most popular paid app on both iOS and Android (in the United States).

AutoCAD 2020 is the latest iteration of this software which was released in December 2019.

Features of AutoCAD

Programming and drawing

AutoCAD is used to design architectural, civil engineering, and manufacturing blueprints. It features parametric drawing, which lets the designer vary the size, shape, and location of a model while design changes are being viewed on screen.

AutoCAD is designed to work within the macroscopic and microscopic environments. Macroscopic environments such as buildings, manufacturing equipment, bridges, and the like are often designed using drawings. Microscopic environments such as atomic structures, circuits, and circuits, are often designed using models. Models can be produced through 2D or 3D computer-aided drafting.


AutoCAD 2D is the main drawing application in the product line and is available in either tablet or desktop versions. It includes a drawing canvas, and a variety of tools and options for creating drawings. The drawing canvas consists of layers which contain features and objects that can be drawn.

When modeling a plan, level, or section, an orthogonal or isometric view can be selected to view the model as a flat, rigid surface.


AutoCAD 3D is the main drawing application in the product line and is available in either desktop or mobile versions. AutoCAD 3D includes a full range of tools, libraries, and functions for creating 3D drawings. The drawing canvas consists of layers which contain features and objects that can be drawn.

AutoCAD was originally developed by Autodesk, then a small company, and it debuted in 1989 as Autodesk AutoCAD (1989). The name AutoCAD was chosen in an attempt to be recognized as «comprehensive design software» rather than as a generic word for CAD. AutoCAD quickly became the standard CAD software package of the architectural, engineering and construction industry. Later the naming concept was applied to a series of other CAD packages, such as AutoCAD LT, AutoCAD Map 3D, AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D, AutoCAD Engineering, AutoCAD Mechanical, AutoCAD Plant and AutoCAD Mechanical PLM. Autodesk acquired a number of competing CAD companies in 2009, including CorelDRAW, and a number of third-party software developers such as T-Rad.

Legacy products include AutoCAD 2010, the successor to AutoCAD LT, and a series of professional packages including AutoCAD 2010, AutoCAD 2013, AutoCAD LT 2015, AutoCAD 2017, AutoCAD LT 2019 and AutoCAD Architect 2017.

Software development history
From 1989 to 1994, the Windows 95 version of AutoCAD used an object model that was not well suited to the Windows API. As a result, the Microsoft Windows team had to change AutoCAD’s development model, and it had to use native Windows code.

Autodesk acquired Softimage in 2001. In 2003, Autodesk acquired Alias, which originally used AutoCAD as its main product. In 2004, Autodesk acquired British-based software design company Inventor, creators of the Simplify 3D and Freedom CAD CAD-modeling systems. In 2005, Autodesk acquired Digitale AG from the German company of the same name, makers of the LiDAR-based BAM modeling and technical design software. Also in 2005, Autodesk acquired the VectorWorks product line of software and acquired FullView Technologies, creators of the FullView CAD-modeling tool.

With the acquisitions of Alias and Inventor, Autodesk added full-fledged 3D CAD and 3D modeling to the core AutoCAD product line. The new Autodesk Inventor product was initially intended to be a 3D design and modeling system. Eventually Autodesk acquired Magnetics Audio in 2006, which had developed an entertainment audio

AutoCAD 23.1 Crack + With License Code

Open the folder where you saved the generated file (in our example it will be called «Test.r3d») and open the.r3d file with Autocad.

In Autocad, go to the menu and choose «File/Import Surface».

At the next screen, choose the one that matches your file type. In our case «3D Model (*.r3d)» and choose «Include only the selected objects».

Then click on «OK».

Finally choose a file location and click on «Finish».

Happy CADing!


How to write C-like printf-style function in Go?

I’d like to write some C-style function in Go.
Please look at example:

static void go(const char *fmt,…)
char buffer[1024];
va_list args;

va_start(args, fmt);
vsprintf(buffer, fmt, args);
«, buffer);

int main()
go(«Hello World %d
«, 123);
go(«Hello World %s
«, «Hello World»);
go(«Hello World %s %d %u %f
«, «World», 3, 4, 5.5);
return 0;

I expect to print Hello World 123, World, World, 3, 4.5 but instead of it I get «Hello World «Hello World «World 123».
My question is what is wrong in my function? How can I fix it?


You need to «print» a slice []byte, you need to fix your vsprintf to return a slice (a slice of bytes). And also you need to pass a slice (or a string slice) as argument to go, rather than pass a slice of chars.
See How to pass arguments to a C function from Go? to know more about the differences between passing slices of strings (or chars) and a slice (or a string) as arguments.
You can try this for an example (I changed your vsprintf to return a slice):
package main

import «fmt»
