AutoCAD 2017 21.0 With Product Key Free Download (April-2022)







AutoCAD Crack +

AutoCAD Cracked Accounts is an extension of the program EasyCAD, a commercial program for the Apple II, released by Steve Mclaughlin and Don Paarsch in 1981. Paarsch initially created EasyCAD in 1979, and Mclaughlin founded EasyCAD Systems in 1980 to market it, which was originally called EasyCAD II. Mclaughlin and Paarsch had previously created a color graphics program for Apple’s Programmer’s Workshop.

EasyCAD II was developed in three phases over two years, and contained software code, documentation and sample graphics. The first version was released in April 1982, and was re-released as EasyCAD II Version 2.0 in March 1984. Version 2.0 introduced an integral text editor and a new font system, along with a 2D topology view.

Later in 1984, Mclaughlin and Paarsch joined Autodesk, where they worked on a 3D modeling program for the Apple II named Autodesk 3D, but discontinued it in 1985, along with EasyCAD II. In the same year, Autodesk introduced AutoCAD Torrent Download, an Apple II and PC DOS application that combined both 2D and 3D drafting features.

AutoCAD was re-released in July 1986 as a DOS application. Version 1.0 was the first release that included true 3D modeling and 2D drafting features. The same year, Autodesk acquired the EasyCAD firm, and integrated its EasyCAD product into AutoCAD.

Following the acquisition, Autodesk introduced AutoCAD LT in 1987, a low-end version of the software. It is targeted towards beginners and would allow basic modeling and drafting features. In 1989, Autodesk introduced AutoCAD R14, the first version of AutoCAD to use pre-rendered 3D images rather than a wireframe model.

In July 1990, AutoCAD Revisions 1 to 9 were introduced, allowing users to preview and print files from previous releases. In 1991, AutoCAD LT 3D and BIML were released, an architectural and engineering program.

By 1993, Autodesk had a list of approximately 80 clients, including Johnson Controls, British Petroleum, and an American aerospace company. It was estimated that between 8 and 10 million AutoCAD users had licensed AutoCAD by that year. In 1994, Autodesk introduced AutoCAD 2000, which was available only on Microsoft


AutoCAD Full Crack has a variety of XML-based APIs.

Geometrical calculation

AutoCAD Product Key supports the “geometric calculation” system, which allows users to define constraints on geometry, and then specify that an algorithm should automatically calculate the geometry that satisfies the constraints. For example, suppose there is a constraint on the length of a length dimension. The user specifies this with a command such as CONSTRAINT LENGTH, which tells AutoCAD that the algorithm should calculate a length dimension with a constraint that its length is less than 10 centimeters. If the user does not want this constraint to be permanent, the command can be followed by the qualifier PERMANENT.

Geometric calculation is not limited to constraints on length; there are many constraints on geometric elements such as areas, volume, circumscribes, centroids, midpoints, and intersections.

In early versions of AutoCAD, it was difficult to specify constraints. To specify constraints, the user could type the constraint into a field on the display canvas, or use a special command such as the FIND CONSTRAINT command, which displays a list of constraints that can be modified.

Although it is possible to calculate the geometry for more than one user in a drawing, geometric calculation cannot make changes to shared geometries (for example, those created by SOLIDWORKS).

In AutoCAD 2014 and later, it is possible to specify geometric constraints by typing them into a text field, and then using a dialog box to select one or more types of geometric constraints. It is also possible to assign a name to a group of geometric constraints, and then use that name as a filter in the CONSTRAINT command.

AutoCAD can calculate geometries for objects that are displayed only in a hidden part of the drawing. For example, a door might be hidden at the front of a house; as a result, its length and height can be calculated.

AutoCAD can calculate the area, centroid, circumscribes, midpoint, and normal of polygons and polylines.

There are many optimization algorithms for calculating geometries. For example, the ANTIC algorithm calculates the optimal solution for an area or a volume. There is an API that allows applications to make use of these algorithms; for example, the IBM Robot Studio uses an algorithm for robot planning.

There is an API for users to “sign up” to be notified when
