AutoCAD Crack + Free Download For PC

One of the first features of AutoCAD that is notable for its power was its recognition that a raster graphics screen, in contrast to a vector graphics screen, has a fixed resolution. This made possible an easy-to-use drawing system with a resolution of 1,280 by 1,024 pixels (1,280×1,024), and saved a user the trouble of varying the resolution each time a drawing is made.

AutoCAD’s raster graphics screen resolution was usually an adequate trade-off for most designers. Even though the graphical quality was far from perfect, resolution was good enough for most designers’ purposes. When a new technology, such as shape editing and wireframing, was introduced, the designers were able to begin working at a higher resolution without worrying about losing quality in the rough drafts that were the norm for many users.

As CAD began to become a standard for the design of digital artifacts, the need for a higher resolution raster graphics screen became apparent. However, AutoCAD could not use a graphics screen of very high resolution without losing quality due to its screen resolution limitations. Although the ability to scale a graphic down in size provided some relief, scaling graphics up to large sizes was not feasible, due to the amount of time that it would take to redraw the scaled graphics.

AutoCAD’s inability to scale up a graphic, or to scale graphics by drawing over old graphics, meant that designers had to work at the screen resolution of the computer they were using, even when working on a display with a much higher resolution. However, a display of a given resolution is not the only factor that may limit a designer’s ability to work.

Since CAD started out as a desktop application, it did not always run well on low-end microcomputers with low-resolution graphics screens. Although it ran well on a higher-end microcomputer, the trade-off for that microcomputer was a higher price. In addition, a high-end microcomputer may have a low-resolution graphics screen that could not display much detail in a CAD drawing. At least, such a microcomputer user could not see much detail in the drawings.

Another drawback with desktop CAD was that it had to be used on a desktop computer. A laptop or other portable computer, although useful for some tasks, could not be used in many of the ways a desktop computer could be used.

Also, certain functions were unavailable on a portable

AutoCAD Crack Keygen ObjectARX is an object-oriented application programming interface for AutoCAD’s Drawing (DXF) file format developed by AutoDesk. ObjectARX allows programmers to create their own extensions for AutoCAD and add custom functionality to the AutoCAD drawing and modelling tools. ObjectARX is an object-oriented programming interface (OOPI) to AutoCAD’s Drawing (.DWT) file format.

AutoLISP is a programming language, based on LISP, which was originally developed for the AutoCAD 2010 product as the CAD scripting language. ObjectARX has been superseded by AutoLISP, which offers a more powerful and feature-rich environment for programming and CAD scripting.

AutoLISP was phased out of AutoCAD after 2013 as the new scripting language ObjectARX was introduced. The AutoLISP language was kept in parallel to ease migration for AutoCAD developers. ObjectARX is not the same language as AutoLISP but adds some additional features not available in AutoLISP.

Visual LISP
Visual LISP is a special-purpose computer programming language for developing applications for Microsoft Windows. The LISP script contains statements (called blocks) that are evaluated in sequence. Each of the statements has a block associated with it. The statement names are not case-sensitive. A statement block is a section of code enclosed in curly braces ({}).

By using one or more statements within a block, one or more procedure calls can be performed. Each procedure call is made with the keyword call followed by the procedure name and arguments. By default, procedures return values to the calling procedure. The LISP interpreter and compiler execute LISP statements that are entered into a buffer or window. A window contains a single set of statements or one statement in a series of statements separated by semicolons (;).

This is an example of a Visual LISP script:

Create a document, add a 2-D plane, and then move it into position using tools from the View menu.

Draw 2-D objects on the plane, and add dimensions to them.

What’s New In?

Improvements to the parameters of topological marking during distance and angle line creation:

Automatically set the base point for the start point and end point of a line when you right-click, in order to draw a line without an extraneous start or end point. Automatically reduce the line by 2 cm to accommodate common survey tolerance.

Performance improvements:

AutoCAD improves and simplifies some important performance aspects of the software. This includes performance improvements in annotations, automatically correcting line geometry for offset lines, improving rendering performance for large drawings, and others.

Ability to select and copy one or more segments of a closed figure (polyline) with a single keyboard command:

You can now move, copy, or paste one or more segments of a closed polyline, simply by selecting the segments you want to copy, and then pressing the keyboard shortcut Ctrl+C.

Improvements to the Automatic numbering option:

Prevent the automatic numbering of edges that would make the drawing frame unclickable. Use the Auto numbering option to force edge numbering at the corners of the drawing frame, which helps to keep the edges clickable.

Two-way copy from a complex shape:

When you copy from a complex shape, such as a polyline, you can now select what parts of the polyline you want to copy. For example, you can select parts of the figure that match the polyline’s individual edges. When you select which segments you want to copy, the polyline is automatically scaled and rotated to match the dimensions of the selection.

Export to PDF or other vector formats:

You can now export your drawing to PDF or other vector formats. Also, you can set the display resolution of the export image, making it easier to create accurate PDFs or print drawings.

Improvements to the dialog box on the file selection dialog:

You can now change the path and name of a file in the file selection dialog without using a complex path and without a lengthy file name.

General improvements:

You can now save a copy of your drawing to a new file location, with the “Save as copy” option.

Impose an “S” to the top of named drawings:

When you add a layer to a named drawing, the new layer will be displayed below the original layers.

Improved handling of ligatures in k
