How to Edit, Move, Copy, Rotate, and Scale Drawings in AutoCAD

AutoCAD is designed to let users quickly create, edit, move, copy, rotate, and scale drawings. The capabilities of the various functions depend on what type of file is being used. When a drawing is used as a layout plan, the drafting features that are available will be limited, as will the functions available for creating and editing text. These limited functions are further limited if the drawing is being used as a template or a general-purpose drawing. If the drawing is intended for use in construction, the available drafting features are broadened, and the editing functions are broader.

The wide variety of available drawing features is a result of the unique features of AutoCAD, the most prominent of which is that the software program can be used as a drafting tool as well as a CAD application.

AutoCAD commands follow the same general format as the commands used in other CAD programs. The following chart summarizes the most commonly used commands and provides an indication of the options available to modify the command. See the Help menu for more information.

Shortcut: Shift + Ctrl + CMD [Functional Assignment]

Shortcut: Ctrl + F [Functional Assignment]

Shortcut: Cmd + F [Functional Assignment]

Use these shortcuts with these commands:

Commands Description f (Functional Assignment) Selects a group of commands, function, or toolbars for activation. Use f to select a group of commands, function, or toolbars. Your default command group is the Functional group. You can select another command group by selecting Customize from the menu and choosing a command group name. Then select OK from the menu.


To select just the Functional group, type f.

To select the Dynamic group, type d.

To select the Dynamic Analysis group, type df.

To select a specific command, type the name of the command. This must be in quotation marks

AutoCAD Crack+ Serial Key

File and memory management
AutoCAD, AutoCAD LT, and AutoCAD Architecture (for Windows) use a memory manager to control allocating and freeing memory. This is a multi-threaded application that is based on a multi-tenant model. It manages memory like a database and utilizes a master server which ensures that work is distributed evenly across the system. In AutoCAD, the allocation of new objects is limited by the capacity of the memory manager to allocate.

The AutoCAD memory manager handles memory in two parts: the system memory and the in-memory allocation. The in-memory allocation is where AutoCAD uses memory to draw objects, run tools, and save documents. The current memory consumption is displayed in the System Information panel. When the system memory capacity is low, the user receives an «out of memory» message, and AutoCAD refuses to launch. The default behavior in AutoCAD 2011 is that in-memory resources are allocated before the system memory. If the memory manager cannot allocate the memory required for in-memory allocation, it fails to launch. If the system memory becomes fully utilized, the memory manager shuts down some or all of the AutoCAD processes.

AutoCAD supports the concept of a buffer pool for storing file and memory objects. When an object is created, its first use is to allocate an entry in the buffer pool. When an object is deleted or no longer needed, its entry in the buffer pool is returned to the free memory list and it can be reused.

Memory model
AutoCAD (since 2009) supports a memory model that addresses issues such as the buffer pool and memory fragmentation. Memory fragmentation, which is an object’s location in a contiguous memory block which is not fully used, can cause the system to fail when the object is needed. The AutoCAD memory model handles the issue by continually moving objects from the buffer pool to the free memory list and back again.

AutoCAD applies a memory model that minimizes the use of system memory, increasing efficiency and reducing memory consumption. Objects which are not in use are not stored in memory. When a user selects and activates an object, all the related objects are first cached in the in-memory allocation. If the object is not used, it is returned to the free memory list and then the system memory can be used again for other objects. If a buffer pool is unavailable, an alternative is to allocate memory using the system memory. All objects are
