AutoCAD 20.0







AutoCAD Crack+ Download

AutoCAD was the first desktop app to include the ability to create two-dimensional (2D) drawings, three-dimensional (3D) models, and technical drawings. More recently, AutoCAD software developers have added significant support for advanced sheet metal design and other architectural projects. AutoCAD can be used for a wide variety of purposes, including creating architectural drawings, technical drawings, custom 3D models, and AutoCAD’s own design application.



AutoCAD is a commercial 3D CAD application developed by Autodesk, Inc. The application is used to create architectural, engineering, or engineering service drawings.

AutoCAD is built on an object-oriented framework, which means that every object in a CAD drawing is represented as an object, or a set of connected or related objects. Each object, in turn, is composed of objects and settings that together describe the attributes of the object. Settings include things like the object’s size, orientation, color, and more. The object’s attributes are read or set through a dialog box called a property inspector, or property palette. These objects, settings, and attributes can be moved, renamed, copied, and deleted, and can be modified individually or in groups. The user can also create a drawing by selecting an available template, such as a 2D architectural drawing or a 3D model. Templates are represented by separate file types that contain a number of data structures, such as the drawing’s overall size, a predefined set of layers and objects, and commonly used settings and objects.

AutoCAD’s drawings are composed of layers. Objects appear on different layers depending on their visibility settings. The visibility settings determine whether or not the object is hidden by the layers in the drawing below it, or whether the object is visible to the user.

The drawing’s layers can be locked, so that the user can’t move, resize, or edit any of the objects in the drawing. Locking layers also provides certain types of security by restricting what the user can do.

When objects are selected, they can be moved, rotated, scaled, and positioned on the drawing canvas using the same tools that a user would use to draw in any other type of drawing program.

You can export to multiple file types, including raster image files, vector image files, and DXF files, and you can publish your drawings to the web.

2000s and later

In 2000, the first version of Autodesk’s Dimension Update was released. It added simple ability to add and edit dimensions in a drawing.

In 2001, AutoCAD Crack Mac was released to all available platforms; the following year, the company released AutoCAD 3D, which became AutoCAD LT. In 2002, the ability to model or import parametric dimensions was added. The ability to edit existing dimensions was added in 2005.

In 2003, the Simple Drawing Property Sheet tool was added to the base software. A toolset for parameterized data entry, complete with parameterized constraints, was added in 2006. Also in 2006, Autodesk released version 11 of AutoCAD. In 2007, Autodesk released the first version of AutoCAD R14, their first release of AutoCAD for the MAC platform.

In 2008, Autodesk released AutoCAD 2008. This was the first version to run on 64-bit Windows and the first to use Windows 7 as its operating system. The final version of AutoCAD 3D 2008 (R13) was released in 2009. AutoCAD Mobile, released in 2009, was a first-of-its-kind application that runs on all mobile devices, including smartphones and tablets, including the iPad and iPhone.

In 2010, Autodesk released AutoCAD 2010. AutoCAD 2010 was the first version to run on Windows 7 Service Pack 1. In 2010, Autodesk released AutoCAD 2011, which was the last version to run on Windows XP. This version also introduced AutoLISP. AutoCAD 2011 also introduced some minor enhancements to the ribbon, including a few more shortcut keys and additions to the ribbon tabs.

In 2011, AutoCAD 2012 was released. This version had many new features including: a new user interface, new features and enhancements to the existing application, new user interface templates, and a new ribbon with several new buttons and tab options. The ribbon now supports several different toolbars, allowing flexibility and uniformity among toolbars. The ribbon now supports drop-downs for each ribbon tab instead of buttons, allowing easier customization for the user. New user interface features in AutoCAD 2012 included: a window shadow, display enhancements, new toolbars, and an updated start menu.

In 2012, Autodesk released AutoCAD 2013. It introduced some new features, including a digital compass and camera features, a new interface

2. Choose “Pipeline Analyzer” from “File” menu
3. Browse and find file “Z:\……\analysis_center.addin”
4. Right click on it and select “Pipeline Analyzer”
5. You will see an option “Run AutoCAD from the command line”
6. This command will create the link for AutoCAD to run with the Pipeline Analyzer.
7. To make sure that this link will work, you need to ensure that all the files are present in the correct paths (the paths are mentioned in the license agreement).
8. Close AutoCAD and AutoCAD Pipeline Analyzer, open AutoCAD
9. Choose Pipeline Analyzer from the “File” menu and choose “Run AutoCAD from the command line”
10. You should see the following output, confirming that it runs successfully.


Can a class be optimized with no polymorphism in it?

Suppose I have a class called Matrix that has two abstract methods: “get_row” and “get_column”.
class Matrix(object):
def __init__(self):
self.matrix = []

def __getitem__(self, index):
return self.matrix[index]

def get_row(self):
return self.__getitem__(0)

def get_column(self):
return self.__getitem__(1)

My friend wrote this Matrix class (named “MoreMatrix”) and he sent me the code:
class MoreMatrix(Matrix):
def __getitem__(self, index):
if self.__class__ == Matrix:
if index == 0:
return self.get_row()
elif index == 1:
return self.get_column()

What’s New In?

Additional updates in AutoCAD 2023 include:

UI improvements: Color gradients are easier to see in the recent feature. Previews are more useful and have a greater resolution. Navigation buttons are more efficient.
