An AutoCAD project is a hierarchical set of drawings that are set up for creating, modifying, or viewing specific sets of drawings. The model on which you create the drawing is not the drawing you create, but rather a visual model for your drawing. If you create a drawing on top of an existing drawing, then the original drawing is the model, not the drawing. If you create a drawing from scratch, then you are the model. Although you are the model, if you then create a drawing, the drawing you create is in fact the model.
Creating your drawing is called “project-creation mode”. The model on which you create your drawings is called the project. There are four project types that AutoCAD supports:
· Simple drawings
· Multipart drawings
· Multipart xrefs
· Central Files (CAT)
The drawings you create using a project can be used alone, or they can be the members of another drawing—in this case, the multipart drawings and multipart xrefs. To see the drawings you have created, you will need to open those drawings.
There are two ways to open the drawings you create: by opening an existing drawing or by opening a simple drawing (called a Master Drawing). The purpose of a simple drawing is to store the basic components of a project, including the project organization and drawing hierarchy.
In order to open a drawing, there are two options: the Open dialog box and the File menu.
The Open dialog box is opened by pressing the Enter key on the keyboard or choosing the Open dialog box in the File menu. The Open dialog box can be used to open existing files or to create new files. In addition, the Open dialog box can be used to open the drawing or file specified in the file path of the first few letters of an entry in the Windows Explorer address bar.
Note: The file name (extension) of a drawing is shown after a dot and the drawing number (it is also the drawing’s Unique ID, and can be used to open the drawing by double-clicking on it) is shown after a slash.
To open an existing drawing, click on the listing in the Open dialog box. You can open a simple drawing file by clicking the Create button. You can also open a.dwg file by double-clicking it.
To open a file path, simply type the path in the dialog box
there are 2×2 thumbnail imageviewer at bottom right corner of the CAD on the windows.
AutoCAD LT, Autodesk’s prior version of AutoCAD, is a free, fully functional AutoCAD viewer. It supports 2D and 3D drawings. On September 14, 2011, Autodesk announced that AutoCAD LT would be discontinued after October 14, 2011.
On April 1, 2011, Autodesk announced AutoCAD WS, a web-based version of AutoCAD.
On April 14, 2011, Autodesk announced that AutoCAD Web Premium, a subscription-based web-based CAD software, would be available on Windows starting May 13, 2011. This is the first web-based release of AutoCAD since 2003’s release of AutoCAD 2002 and the first public release of AutoCAD since 2007’s release of AutoCAD R14.
AutoCAD supports both DXF and DWG (XML) 2D and 3D files (for example: DGN files). It is available on Microsoft Windows, macOS and Linux. Autodesk released a free cloud-based version called AutoCAD 360 in February 2015. Autodesk also offers a Free version which is available for schools or individuals on a trial basis.
AutoCAD 2009 included a new option for creating and modifying a binder.
New features include:
FAB-LK: “Freehand Line Keys”, providing the ability to interactively trace a line without moving the cursor.
DDD/DDO-LK: “Dynamic Dimension Line Keys”, which can be used to create dimension lines with just one keystroke, making the creation of dimension lines quick and easy.
SWITCH: This allows a user to create a new view and see both the dimension and model in the same view.
2D/3D HOVR: “High-Order Vector Replacement” allows the dimensions of the drawing to be scaled with a HOVR view.
SWITCH: “Switch” allows a user to view two different views of the same drawing on the same screen at the same time.
CAPS LOCK: Allows the user to have a full caps lock key on their keyboard when working in AutoCAD.
MONOCASTE: Allows multiple annotation layers to be created on the same drawing.
POWER, MAP and SURFACE: These three new commands allow the user to select and modify

Clicking an error message in the drawing pane displays a short description of the problem and shows the location of the object.
The attributes of the source object are imported when AutoCAD imports an object from another CAD application.
When you import a model from another application, the units of your model are automatically converted from the units of your originating application to the units of your new drawing.
You can display the AutoCAD annotation and selection tools in their own submenu.
You can define a context that can be applied to multiple drawings.
You can import alternative named objects, such as dimension lines and splines, and the names are retained when you rename the object.
You can import and export color schemes from a palette.
You can use the Textures, Patterns, and Transfers palettes to apply textures, patterns, and transfers to existing drawings.
You can use the dimension lines, splines, arcs, and fillets to generate editable dimensions, guidelines, and knots.
You can edit the color of all strokes in one tool.
You can import commands from other drawing packages or drawings.
You can use the Visible Structure setting to make parts of an object visible or invisible.
You can import, edit, and export the FCL properties of drawing components and drawings.
You can annotate and annotate visible text.
You can label geometry with SnapToGrid, SnapToPoint, and SnapToShape to align geometry to lines, points, or shapes in your drawing.
You can use the Label from Selection command to annotate the geometry you are drawing.
You can display the current axis, which is useful for aligning drawings to another drawing or for specifying the axis of a 3D model.
You can draw line geometries in 2D or 3D.
You can view and edit dimensions on top of a surface.
You can run a host of new C++ macros from the ribbon to perform various types of tasks, such as cut and copy.
You can run the Find Commands command and the Find and Replace commands from the ribbon.
You can edit attributes of linked drawings.
You can display the dimensions of a drawing or model in one window.
You can double-click to display the corresponding
