ELSA POWER

What Is ELSA POW ERdraft?

Integrated Driver

ELSA POWERdraft is a Quadro workstation application utility.

The driver software is integrated into the AutoCAD environment. 32-bit display list technology and knowledge of the NVIDIA graphics adapter are combined to provide significant improvements over existing driver technology.

Note: The AutoCAD display driver (WHIP!) is part of the AutoCAD plotting engine,

which is a new feature in AutoCAD 2000. ELSA POWERdraft replaces the “WHIP!” display pipeline, but does not replace the “plotting” pipeline or affect the AutoCAD plotting functionality.

Utilities

The ELSA POWERdraft driver includes the MagniView, MultiView, and Cockpit utilities that enhance the AutoCAD drafting environment without interfering with its functionality. Fully dynamic and integrated through the NVIDIA SmartFocus technology, each utility is transparent to AutoCAD and available during any AutoCAD command.

DRAFT

VERVIEW

1. The NVIDIA SmartFocus technology is used in all ELSA POWERdraft windows to eliminate switching of Windows input focus between ELSA POWERdraft utilities and the AutoCAD drafting window. After you use a function in an ELSA POWERdraft utility, keyboard input or cross hair movements will immediately make the AutoCAD window the active window; you don’t need to click the mouse as with other drivers.

Cockpit

Cockpit lets you use your pointing device to dynamically pan and zoom the AutoCAD view. Fully integrated into the AutoCAD MDI (multiple document interface) environment through the NVIDIA SmartFocus technology, Cockpit has an easy-to-use graphical interface that lets you take full advantage of the enhanced ELSA POWERdraft performance.

MultiView

Also fully integrated into the AutoCAD MDI environment, the MultiView utility provides a visual history of previous views, where each view is represented on a button face. Instant access to previous views allows you to record and playback selected views in a consistent manner. Using MultiView, you can also efficiently manage AutoCAD Named Views.

MagniView

The MagniView utility functions as a graphical magnifying glass for detailed viewing.

Toolbar

The ELSA POWERdraft toolbar provides convenient access to several ELSA POWERdraft commands.

Hot Keys

For common actions—such as Pan, Zoom, and Redraw All—ELSA POWERdraft provides configurable key combinations called Hot Keys. Hot Keys work transparently and are always accessible within AutoCAD.

3D Hardware Renderer

To support AutoCAD 3D functionality, the 3D Hardware Renderer accelerates AutoCAD 3D viewing modes such as 3D Orbit or Gouraud Shaded.

Drawing Optimization

ELSA POWERdraft provides a configurable Display Update cache to accelerate the execution of Lisp scripts.

Online Help

When you have any Workstation Applications window open, press F1 to display online Help, which provides detailed user information about the application. You can also view the Help outside the application.

Model space views are restored to the last active viewport.

• If unchecked, restoring a model space view from a Layout tab leaves that Layout tab as the active tab. In this case, model space views will be restored to a floating viewport.

• If checked, model space views are restored to the last active “model space capable” viewport, which may imply a previous switch from a Layout to Model tab.

Accelerating 3D Viewing with Hardware Renderer

Accelerated 3D Viewing Modes

AutoCAD 2000 uses the ELSA POWERdraft 3D Hardware Renderer to accelerate the following 3D viewing modes:

• 3D Orbit

• 3D Wireframe

• Hidden-line

•Flat Shaded

• Gouraud Shaded (with Edges On and Off)

Configuring the 3D Hardware Renderer

After ELSA POWERdraft is successfully installed, the 3D Hardware Renderer is already configured for use with AutoCAD 2000.

To change the AutoCAD 3D graphics configuration

1 Click the Tools menu, then click Options to open the AutoCAD Options dialog box.

2 Click the System tab.

3 Click Properties in the Current 3D Graphics Display group box. The 3D Graphics

System Configuration window opens.

Acceleration configuration section.

4 Select the driver you want in the Acceleration box, and then click Apply and Close.

The original configuration of AutoCAD is Software. The ELSA POWERdraft configuration is Hardware with driver file NVIDIA6.HDI for AutoCAD 2000 based applications, or Hardware with driver file NVIDIA7.HDI for AutoCAD 2000i and AutoCAD 2002 based applications.

Accelerating Lisp Scripts with

Accelerating in Non-Interactive Mode

When Drawing Optimization is enabled, POWERdraft caches the graphics output while AutoCAD is in non-interactive mode.

The configurable Display Update cache accelerates Lisp scripts and, depending on the Lisp script, may significantly accelerate the execution of AutoCAD.

Configuring Drawing Optimization

To configure Drawing Optimization:

1 From the Menu bar, click ELSA POWERdraft ->

Settings.

2 Click the General tab.

Drawing Optimization

Adjust slider to select the degree of caching.

3 Inside the Display Update group, adjust the slider to one of four positions.

Immediate Update: No caching—the display is updated immediately.

•

Intensive Caching: Maximum display caching. The display is updated

•

approximately every 2 seconds.

• The two intermediate settings provide progressively lower levels of caching from the

maximum.

The degrees of caching apply when running scripts (such as a Lisp scripts), and do not apply in interactive mode. When AutoCAD enters interactive mode, no caching is performed and the display is updated immediately.
