Historical Relevance
AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk, AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers. Before AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal.
AutoCAD initially ran only on PCs with a 16-bit video adapter and an internal raster graphics device such as the DEC VAX-11/780 or 8088–based Apple IIe. With a typical hardware cost of $10,000, its initial price was about $1,500. Despite the price, AutoCAD was quickly adopted by the architectural, engineering, and manufacturing communities and remained a dominant force in the industry for the next 20 years.
AutoCAD was released as AutoLISP before the 1985 introduction of the Macintosh platform. It remained the only Autodesk product with native support for the Mac until 2002, when the company released a 64-bit version of AutoCAD.
AutoCAD was originally developed using an object-oriented programming language called AutoLISP. AutoCAD’s user interface was initially based on the toolkit graphics program called ABLE; as AutoLISP became more popular and AutoCAD grew into the largest software program of its kind, the company modified its object-oriented development system, calling it “ACE” (from Autodesk Embedded). The most recent version of AutoCAD (AutoCAD 2018) has been released under the title AutoCAD LT, as part of the Microsoft Windows software platform.
AutoCAD LT replaced AutoCAD on PCs. On Windows, AutoCAD LT was initially an AutoLISP program that was compiled to a native Windows app using ACE.
AutoCAD LT came in two versions: $649 Professional, and $399 Student.
AutoCAD LT 2018 is the current release for the Windows platform. The main difference between AutoCAD LT 2018 and its predecessors is the introduction of Microsoft SQL Server as a database backend, replacing the previous Sybase OpenEdge database, which was replaced by Microsoft Access.
AutoCAD LT 2018 is also available for macOS, although the interface is different due to the absence of an internal raster graphics device.

Formats
Two important file formats, “Drawing” and “DWG” are natively supported. These are the top-most level of the DGN and are used by AutoCAD to create drawings and exporting. The “Drawing” is the only format that can be loaded and saved in any version of AutoCAD. A “Drawing” can be exported to several formats such as, PDF, SVG, DWG, DXF, VRML, 3D, etc. The “DWG” format was introduced with AutoCAD 2002, which is typically used to save the drawings of architectural models.
Drawings
The “Drawing” is a binary format natively supported by AutoCAD that contains all objects in the model along with their geometric and non-geometric properties. Drawing can be exported to several formats such as, PDF, SVG, DWG, DXF, VRML, 3D, etc. It contains all the information required to display a drawing in any view or printing, and information is always saved automatically.
The DWG file is based on the Draw4Autocad format, a binary format to save 2D CAD drawings. AutoCAD is a native DWG software application that allows users to edit, print, and export drawings. It is a proprietary format developed by Autodesk and is used to save the drawings of architectural models. DWG was first released with AutoCAD 2002.
Exporting to CAD
The capability to export drawings to AutoCAD is available since AutoCAD LT version 1.0. Before AutoCAD LT, AutoCAD had the ability to export to DGN, now known as DWG, which is a native format.
Another native DWG file format, DWGP, was also available in Autodesk 3D Studio Max for many years.
Drawing features
The core features of the “Drawing” are explained below:
It contains all the information required to display a drawing in any view or printing.
It automatically saves geometric and non-geometric properties such as text and annotation into the DWG file.
It contains layers, and supports multiple view.
Views
Autodesk provides a view of a drawing that provides the most commonly used views in AutoCAD, and is the tool used by designers for the creation and construction of architectural designs.
These views are available to the user when

Revive the Align markups in AutoCAD to use them together with the DWG format and to allow them to be reused. Use the new alignment styles to make complex markups appear visually consistent. The object tracking and alignment tools now work together with DWG files.
Improvements to the Unicode character system to allow more unique characters. Character abbreviations are now supported, and there are improved properties and scaling for other unicode characters.
New MText, MapEdit, MapInfo and MapSurfer data formats.
New import and export filters for Excel.
New: Added Application Performance Profiler. (video: 2:39 min.)
Drawings Export:
Export Drawing Data (XML) to Sharepoint for use with Power BI.
Export Drawings to DWF, DXF, DWG, DWFx, PDF, SVG and DXF.
Export to Illustrator (a.ai file).
Export to HTML.
Export to PostScript, Raster, Vector, SVG and PDF.
Export to Excel (XLS, XLSX).
Tabs Import:
Import drawing tabs from DWG files into AutoCAD.
Outlines and Layers:
The Outline style now supports hidden elements. This helps to hide repetitive groups and objects in an outline. The new shape constraint line tool now supports the options to show and hide the shape constraint lines.
Group objects based on the current selection. The Selection Group command allows grouping of objects based on the current selection.
A new dynamic Outline Style Editor tool enables you to quickly modify the Outline Style of an object with a drag-and-drop. The new InPlace Outline command enables you to outline and group objects in existing drawings.
Layer objects by any combination of their bounding boxes, or by any selected features.
Unique sub-sorting and filtering for layers that support a hierarchical structure.
Visual styles and effects are now reflected in the Outline Style editor and Layer Style editors.
The Options Bar now lists a “Load Subset” option to open a subset of drawing files.
Outline Options dialog box now allows you to select which points to show on an Outline in addition to the properties of the Outline.
