AutoCAD Open or Save a Drawing

You can use several methods to find and open drawings, even damaged drawings. You can save and backup drawings automatically. Technical Data used in the field explained in autocad course in Rawalpindi.

Open a Drawing:

You open drawings to work on them just as you do with other applications. In addition, you can choose from several alternative methods. Some more details about this field of autocad course in rawalpindi are as under. To open a drawing, you can

■ Use Open on the File menu to display the Select File dialog box. If the FILEDIA system variable is set to 0, the Command prompt version displays instead of a file navigation dialog box.

Double-click a drawing in Finder to launch AutoCAD® and open the drawing. If the program is already running, the drawing opens in the current session.

■ Drag a drawing from Finder onto the AutoCAD icon in the Dock. If you drop a drawing anywhere outside the drawing area—for example, the command line or the blank space next to the toolbars— the drawing is opened. However, if you drag a single drawing into the drawing area of an open drawing, the new drawing is not opened but inserted as a block reference.

■ Use the Project Manager to locate and open the drawings in a project data (DST) file. Work on Drawings During Loading You can work on drawings before they are fully open. This is useful when you work on large drawings and you want to begin working immediately. To take advantage of this capability, three conditions are required.

■ The drawing must have been saved in paper space.

■ The INDEXCTL system variable must be set to a non-zero value.

When these conditions are met, you can create or modify visible objects, pan or zoom, turn off or freeze layers, and any other operation that does not require displaying objects not visible when the drawing was last saved.

Work with Large Objects:

AutoCAD 2010 supports object size limits greater than those available in previous releases. With increased object size limits you can create larger and more complex models. Using increased object size limits can result in  compatibility issues with legacy drawing file formats (AutoCAD 2007 and

earlier).

When working with drawings that you might need to exchange with others using AutoCAD 2009 and earlier, set the LARGEOBJECTSUPPORT system variable to 0. Setting LARGEOBJECTSUPPORT to 0 warns you when a drawing contains large objects that cannot be opened by a release of the program prior to AutoCAD 2010.
