AutoCAD 23.1 Patch With Serial Key PC/Windows (Final 2022)

AutoCAD is a cross-platform CAD software application, and is available for Microsoft Windows (x86), macOS (x86, x86-64), and Linux, and for mobile devices including Android, iOS and Windows Mobile. The software is fully interoperable with other popular CAD software, and has been part of the Corel Software ecosystem since 2010.


The following tutorial was first published in 2010 and was updated to include the 2015 and 2017 releases of AutoCAD as well as most of the CorelDraw 2016 software suite. All details are included, but readers should have basic knowledge of the software applications used.


This tutorial provides an introduction to drawing in AutoCAD, with the aim of enabling students to create basic shapes and linework, and to use perspective projection to draw complex geometries. The tutorial contains two models, a 2D and 3D drawing, which is suitable for students at a suitable stage of their studies.


This tutorial introduces the concept of drawing in AutoCAD, and provides the information needed to learn how to use the application in a productive way. The tutorial is not designed to teach students how to use the software, but to introduce them to the range of tools available for use in the application. The tutorial covers the following topics:

The concepts of drawing in AutoCAD

Creating a new drawing

Drawing basic objects in 2D

Navigating and manipulating the drawing environment

Drawing and editing components

Understanding the coordinate system

Manipulating objects using the drawing interface

Drawing using the Graphical Edit Tool

Drawing and editing linework using blocks

Using the drafting features

Understanding the concepts of drawing

In AutoCAD, a drawing is a specific type of model that has a defined set of properties. A drawing is therefore a 2D or 3D representation of an object, and is composed of objects, lines, and blocks, in which each object has a specific purpose, and may be composed of other objects and blocks. AutoCAD therefore has a number of different types of objects that can be used to represent specific types of geometric entities. For example, the AutoCAD drawing environment has the following objects:

Components (also referred to as properties)

(also referred to as properties) Lines

(also referred to as blocks) Properties

(also referred to as blocks)

Render engine
The AutoCAD Activation Code LT 2016 software release introduced a new 3D engine called Rendu, which uses the Allegro Graphics Library. Rendu is the first Autodesk platform to utilize Allegro, and can render to the 2D and 3D formats, plus its own format (called Revu). It supports a wide range of surfaces, and can export to a number of 3D formats. It also supports higher levels of color.

The syntax of AutoCAD is based on the structure of a programming language. Its syntax is a combination of the ASCII character set and the Basic programming language. It also draws from the LISP programming language, especially its s-expressions, because AutoLISP was used to create the earliest versions of AutoCAD.

Object orientation

AutoCAD can take advantage of object orientation, with classes and objects to store configuration data. A 2D class with attributes, properties, methods and properties can be described using an object-oriented programming language, such as Visual LISP. The classes form the basis for multiple-instance objects, which enable drawing at different levels of detail. This is similar to AutoCAD’s 3D model.

The LISP programming language allows the definition of object-oriented programming language: classes, methods, properties, and properties. A class is an object, and each instance of the class has its own variables. The data types of a class are variables. Properties are stored in each instance, and functions can be called from each instance. A 2D class is represented by an element, and a 3D class is represented by a block.

LISP supports functions for each element. A function is represented by a name, parameters and return values. Two functions can be written in LISP that are equivalent:

((defun c1 (x)
(+ x 1))
((defun c2 (x)
(+ x 2)))

The above code would produce the following values:

c1: 5
c2: 3

The functions c1 and c2, when called, would return the following values:

c1: 5
c2: 3

Unary operators (prefix forms)
The AutoLISP programming language, one of the features used in AutoCAD, is largely an extension of the programming language Lisp. The logical and operator in AutoLIS

Struts 2 interceptor not working

I’m having trouble getting my Struts 2 interceptor to work. I’m simply trying to keep a counter from being incremented when a specific action is run and display the results in the view. I have the JSP working properly, so that is not my problem, just the interceptor. I believe my code is correct, but when I run the app, nothing is displayed. I’ve tried to remove all Struts 2 code from the application and just keep the interceptor working with nothing else, but that still doesn’t work. Any ideas on what I might be doing wrong?

Summary of Environmental Practices:

What’s New In AutoCAD?

Substructure and Complexity Styles:

Create and annotate shape structures with more detail and fidelity. Style based on directed and context-based analysis of the structure, with functions including colored and shadowed views, textured views, and border and fill styles.

The ability to add direct relationships between layers. You can also create and apply layer relationships automatically as you create a drawing.

Accuracy and Retentiveness Improvements:

New AutoCAD drawing tools: Measure, Fit, FitTo, Slide, and Slip. When you define a distance to measure, a tool shows up and you’re ready to measure. You can also use Fit and FitTo tools for other shapes and objects. The Slide tool enables you to create and edit a slide along a given path.

Handling and Graphic Zoom Improvements:

Simplify the process of creating documents and settings for print layouts, which are now easier to manage.

New AutoCAD Tools:

Arc, Polyline, Polygon, Cylinder, and PolarCylinder tools create and edit polygons and polylines. The Twist tool rotates a closed path along a spiral. The Hook tool extends a line segment and creates a right-angle bend. The Axes and Ellipse tools create grids and circle templates. The Intersect tool creates polyline and polygon intersections.

The Union tool merges polylines, paths, and multiline objects. The Polyline Intersect tool intersects lines and polylines. The Polyline to Spline and Polyline to Multiline tools convert polylines to spline or multiline objects. The Circumscribe tool creates a frame around a closed shape. The ConvexHull tool creates a convex hull around a polyline or path.

The LineTo3D and PolylineTo3D tools convert polylines and multilines into 3D line segments or polylines.

The BezierCurve interpolate and AutoBezier interpolate tool enable you to create and edit Bezier curves.

The AsShape tool is a conversion tool that lets you convert polylines and polyline, multiline, and spline objects into arcs, circles, ellipses, and rectangles.

Some of the following new tools are hidden in new user interface (UI) features, like the expanded Object Browser. The tools are described in “New Tools” later
