AutoCAD Crack + [Updated] 2022

Since the introduction of AutoCAD, it has become the most popular CAD tool used by architects, engineers, and drafters. More than 36 million users around the world use AutoCAD to design everything from buildings, bridges, pipelines, and trains to surgical instruments and airplane parts.[1] AutoCAD offers the most features of any CAD program, but it is not widely used in construction or production industries due to its complexity, steep learning curve, and high price.[2]

In 2009, Autodesk sold AutoCAD to Chinese private equity firm Lenovo, marking the company’s first acquisition.[3][4] Autodesk also acquired the rival SketchUp program in 2013.


AutoCAD’s name comes from the first letters of “automated” and “cadastre”, the Spanish word for registration. In the 1970s, drawing technology was still primitive, and CAD software was needed to manage the large amount of data used in architectural design. On the mainframe computers that most CAD programs ran on at the time, each designer used a separate graphics terminal connected to the mainframe through a data cable and separate telephone lines.[5] AutoCAD introduced a line-by-line system to manage the design of architectural structures, where each line represents a single structural element. The software was introduced in 1982 to the market as AutoCAD, an acronym for “Automated Constructional Drafting”, to avoid being confused with “automobile” or “automation”.[6]

AutoCAD 1.0 was released on December 19, 1982.[7] AutoCAD was first installed on a Zilog Z80 microprocessor-based system that replaced an existing minicomputer. It was able to output to nine different graphics terminals and could import common CAD files from Xerox and Adobe.[8] AutoCAD ran on a new operating system, DOS/MS-DOS, which was developed by Microsoft. In June 1986, AutoCAD 2.0 was released, featuring a new user interface, printer support, and the first version of AutoLISP.[9][10]

In 1987, the software started being shipped in boxes with a CD-ROM instead of the documentation paper.[11] In 1990, AutoCAD Extended (ACE) was released. ACE added a user-definable grid to the drawing canvas, multiple layers, and the ability to insert text and dimensions on the objects. In 1990, AutoCAD

AutoLISP is a macro programming language that is used for programming AutoCAD in both the Drafting and Annotation views.

AutoLISP is a functional programming language, with object-oriented programming features.

The AutoLISP object hierarchy is similar to other object-oriented programming languages. As an example, let us consider the following series of statements, which creates the following symbols:

ValueError: non-unique counter for label

I’m making a classifier for food types using a CNN model, and I am receiving the error

ValueError: non-unique counter for label

I assume that this is because of the variable len(labels_name) as the script uses a lot of labels, but I have no idea how to fix it. The labels are mapped from the data file, and the labels are names of food types.
Any suggestions?


The solution is to use a python dictionary and label the label names to the indices, for example labels_name[“chicken”] will be “chicken”.

Dose-dependent antagonism of oxotremorine-induced ptosis in mice by nicotine.
We investigated the effects of i.p. administered nicotine on ptosis induced by oxotremorine in mice. Nicotine at doses of 2.5-5.0 mg/kg produced a dose-dependent antagonism of ptosis induced by oxotremorine, whereas a dose of 10 mg/kg, which is about four times the effective dose, potentiated oxotremorine-induced ptosis. The alpha 4 beta 2-subtype nicotinic receptor agonist talsaclidine also produced a dose-dependent antagonism of oxotremorine-induced ptosis. The results suggest that endogenous acetylcholine in the brain modulates the muscarinic receptor system in a dose-dependent manner.When the man became a captive of the Quar’rax he found his heart broken by the extreme heat, so he ordered all of the slaves to go to the river and cook food to get rid of the heat. The Quar’rax who was building a barn inside of it, became surprised by the fact that the slaves had been able to cook the food, and he ordered the slaves to be killed so that he could build his barn in peace. The man then vowed revenge against the Quar’rax who had killed his wife and children, and they have not left each other’s side since.

According to the man’s survival story, the Quar’rax cannot speak, but only screams. When the man cut off the creature’s hand it began to scream in pain and so the man cut off his head.


The Quar’rax is a rather tall and deformed creature with numerous claws on his feet and

AutoCAD will read the same text from a file or import CAD data from Excel, MS Word, and Open Document text formats. Make sure that you read the detailed help information to learn how AutoCAD can read your text.

If you need to import data from paper, AutoCAD 2023 provides improved methods of reading Post-it notes, index cards, and more.

Wherever you are in the drawing creation process, you can still open, resize, edit, and manipulate AutoCAD objects and drawings in a number of different ways, including Tablet, mouse, and keyboard. You can navigate with either the mouse or the pen and stylus.


The ribbon layout is enhanced. You can now choose a tab for commands, drawing views, ribbon layouts, and panels.

All panels now have a ribbon that is connected to a specific tab.

When you select one of the tabs, it will display the buttons associated with it in the ribbon.

The majority of drawing views are now collapsible to reveal more work space.

View | Collapse All draws all drawings views except the one you are currently viewing in to the bottom of the screen.

View | Pane | Collapse All draws all drawings views and all panes to the bottom of the screen.

When you collapse the drawing window, you can see more work space by selecting View | Undock.

The Help menu has been completely redone. The Help Topics screen now contains a comprehensive set of AutoCAD help topics that
