If Fast Zoom is disabled, the drawing is regenerated at the completion of the ZOOM command. If Fast Zoom is enabled, you can use ZOOM Dynamic to change the current drawing view without regenerating the drawing. Right-clicking your pointing device in Realtime Zoom or Pan displays a cursor menu that enables you to switch between Zoom, Pan, Zoom Previous, and Zoom extents.ДЇast Zoom is a new option of ZOOM Dynamic. Realtime Zoom and Pan are now options of the ZOOM and PAN commands. Tracking constrains point selection to an orthogonal path. Tracking is unlike point filters in that a tracking point cannot snap to itself. Tracking combines both X and Y point filters and enables you to use them on the fly. Tracking is a new drawing aid that enables you to visually locate points relative to other points in your drawing. To change plotter configuration settings, you must use the PLOT command. To plot the drawing using the current configuration, select Plot. You can now use Real Time Zoom and Pan within the PREVIEW window. The new PREVIEW command enables you to view a drawing you are about to plot in Microsoft standard layout format. You can set this option with the Compatibility tab in the Preferences dialog box. The new system variable OSNAPCOORD enables you to override object snap settings with coordinate entry or settings made in a script. The Osnap button on the status bar enables you to switch object snaps on and off without losing your settings. AutoSnap settings can be changed on the AutoSnap tab in the Osnap Settings dialog box. You can press TAB to cycle through all the snap points available on the object. The performance benefits of demand loading are most noticeable when you either clip the xref to display a small fraction of it and a spatial index is saved in the externally referenced drawing, or when you freeze many layers of the xref and the externally referenced drawing is saved with a layer index.ДЄutoSnap is a new option of Running Object Snaps that indicates the snap points on an object with a colored marker and a tooltip as your aperture box moves over an object. When demand loading is enabled, AutoCAD loads into memory only the portions of the referenced drawing that are necessary to regenerate the current drawing. The 3D features, ACIS solid modeler, Image Support Module, DRAWORDER command, Multiline Text Editor, external databases, Match Properties, Internet Utilities, and Render are now demand-loaded ARX applications which only need to be loaded when they are used.Дemand-Loaded Externally Referenced Drawings (Xrefs) Modular Application Structure (Application Demand Loading) If you use the hatch feature frequently, you can reduce your drawing's file size and memory consumption significantly, as well as speed up drawing load and regeneration time. Hatch patterns are also now stored as single objects, which occupy less space in your drawing. If you use polylines frequently, you can reduce your drawing's file size and memory consumption significantly, as well as speed up drawing load and regeneration time.

Polylines are now stored single objects, which occupy less space in your drawing. The maximum number of active viewports in paper space has increased from 16 to 48. Transparent Zoom and Pan, and Realtime Zoom and Pan are both enabled in paper space. Regenerations in paper space following a zoom or pan operation have been almost completely eliminated. Replacement of AutoCAD ADI graphics pipeline with a modern, HEIDI-based graphics system has eliminated the refresh file and its memory demands. Drawing Productivity Enhancements -AutoCAD Release R14
