Troubleshooting

If you experience problems when running Adobe Reader 7.0, this section may help you to determine the cause of those problems. For general product information and additional troubleshooting information, visit the Adobe Product Support Knowledgebase at www.adobe.com/support, or choose Online Support from the Help menu in Adobe Reader.

• The Help and How To windows are not available when you open Adobe Reader from within a web browser. To access the Help button or the How To window from a task button, start Adobe Reader from outside of a web browser troubleshooting information, visit the Adobe Product Support Knowledgebase at www.adobe.com/support, or choose Online Support from the Help menu in Adobe Reader.
• The Help and How To windows are not available when you open Adobe Reader from within a web browser. To access the Help button or the How To window from a task button, start Adobe Reader outside of a web browser.
• The Detect And Repair feature in Windows repairs or replaces corrupt or missing installation components.
• You can drag the How to window anywhere on-screen. If you move the window from a docked position, it becomes a floating window and can be resized only by dragging the lower right corner. To re-dock a floating How To window, Control-click below the title bar and choose Docked Left or Docked Right. For more information, see the Adobe Reader Help.
• The Enter key and the spacebar function differently in the Accessibility Setup Assistant in Windows and Mac OS. In Windows, both the Enter key and the spacebar close the wizard. In Mac OS, the Enter key advances the wizard to the next page and the spacebar closes the wizard.
• Windows XP and 2000 include Microsoft Magnifier, an accessibility tool that uses the MSAA interface. When started, this tool activates acces¬sibility in Adobe Reader until you quit Adobe Reader. Each time you open a PDF document, the following message appears, "Please wait while the document is prepared for reading." To reduce the time that Adobe Reader requires to prepare a PDF document for reading, set the Page vs. Document preference to Only Read The Currently Visible Pages in the Reading Preferences. Setting the Reading Order preference to Use Reading Order In Raw Print Stream also speeds up this process but may interfere with the functionality of Magnifier.
• To improve the startup time and performance of Adobe Reader, defragment your hard drive by using the disk defragmenting utility before you install Adobe Reader. You can use the disk defragmenter included with your operating system or a third-party utility. Hard drives become fragmented through normal use (for example, installing and uninstalling applications, adding and deleting files). Over time, the computer is unable to locate contiguous blocks of free space and saves files in pieces across the hard drive, which increases the time required to open these files. Defragmenting the hard drive pieces files back together and improves performance.
• If you scan a PDF barcode into Notepad using a handheld scanner, the resulting data may contain null bytes or illegal characters (characters that can't be typed at the keyboard). This data may execute desktop shortcuts that cause windows to open. The problem doesn't occur with all handheld scanners. No solution exists.
• When you try to start Acrobat Reader in Windows 2000 after installing it on a non-system hard disk, the Acrobat installer starts and returns the message, "An installation package for the Microsoft Windows Journal Viewer cannot be found." See document 329118 in the Adobe Product Support Knowledgebase at www.adobe.com/support.
• If you open a PDF file in AOL 6.0 to 9.0, the file opens in a text editor. Save the PDF file to the hard drive and open it in Adobe Reader.
• Mac OS X v.10.3.x or later and Safari 1.2.2 or later are required to use Adobe Reader in a browser window.
• Although Adobe has tested Adobe Reader 7.0.7 on future versions of Mac OS, these operating systems aren't supported by Adobe Reader as final testing wasn't completed when Adobe Reader 7.0.7 was released.
• If you paste the CJK-A character U+3400 into the search field and perform a search, the search fails even if the character exists in the PDF document you're searching. The same applies to the U+3500, U+3600, and U+3700. Type the U+3400 character in the search field instead of pasting it.
• If you install Adobe Acrobat Elements 6.0 after installing the full version of Adobe Reader 7.0, you may encounter an error in Acrobat Elements when you try to convert a file to PDF asking if you want to run the installer in repair mode. If you click Yes, the same error appears the next time you try to convert a file to PDF in Acrobat Elements. Install Acrobat Elements 6.0 before you install Adobe Reader 7.0.7 to ensure that both applications are installed in the same folder. (Acrobat Elements 6.0 doesn't allow you to specify the install location.) Please note that Installing Adobe Reader 7.0.7 doesn't remove Adobe Reader 6.0, which is installed by Adobe Elements to the same folder. This installation of Adobe Reader 6.0 (unlike the downloaded version) doesn't interfere with Adobe Reader 7.0.7 functionality.
• If both Acrobat and Adobe Reader are installed and you uninstall either application, you must run Help > Detect And Repair in the remaining application. Acrobat and Adobe Reader share required components.

Shortcut keys

Hebrew, Arabic, Thai, and Vietnamese Text

This version of Adobe Reader supports the entry and display of Hebrew, Arabic, Thai, and Vietnamese text.

Arabic and Hebrew language support

This version of Adobe Reader contains options for controlling the following aspects of the right-to-left languages Arabic and Hebrew in forms and digital signatures:

• Paragraph direction--You can select the paragraph direction to be from right to left, which properly lays out bidirectional text (right-to-left text containing numbers and text in other languages written from left to right).
• Digit style--You can select whether to use Western digits or Arabic-Indic digits when typing Arabic text.
• Ligature support--available only to Arabic text, optional ligatures will be automatically used if supported in the font.

To enable right-to-left language options in Adobe Reader:

1. Choose Edit > Preferences.

2. In the Preferences dialog box, select International Categories and select Enable Right-To-Left Language Options.

3. Click OK.

Enabling right-to-left language options displays the user interface elements for controlling paragraph direction, digit style, and ligature.

Note: The right-to-left language option is enabled by default under Arabic and Hebrew regional settings.

The following user interface elements let you control paragraph direction and digit style:

• Appearance tab of the following dialog boxes: Text Field Properties, Combo Box Properties, List Box Properties, and Button Properties, and Digital Signature Properties. In these dialog boxes, you select paragraph direction using radio buttons and you select digit style using pull-down menus. In the Radio Button Properties and Check Box Properties dialog boxes, the options to select paragraph direction and digit style are not available.
  The Appearance tab for the Digital Signatures Properties dialog box provides the digits style selection. The text direction of digital signatures is controlled by the Configure Signature Appearance dialog box available when a signature is applied to the document.
• Text Field Properties toolbar--When entering text in a Rich Text field or a Drawing Markup Text Box, you can select paragraph and font direction and digit style from the Text Properties Tool Bar.
  To change paragraph direction, use the Paragraph Direction button in the toolbar. Clicking this button displays two options: Left To Right Paragraphs and Right To Left Paragraphs, which apply to all paragraphs in the field. Paragraph alignment automatically changes according to your selection: if paragraphs are left-aligned and you change the paragraph direction to right-to-left, Adobe Reader makes all the paragraphs right-aligned, and vice versa. After changing paragraph direction, you can go back and modify the alignment of paragraphs individually.
  To change text direction of selected text and not entire paragraphs, use the Text Direction button to display a pull-down menu with three options: Automatic, Left To Right Text, and Right To Left Text. Selecting the Automatic option lays out the text depending on the paragraph's direction and the type of characters used. The Left To Right Text option lays out the text according to left-to-right rules, regardless of paragraph direction. The Right To Left Text option lays out the text according to the right-to-left rules, regardless of paragraph direction. Changing text direction is useful when the default writing direction for text in a paragraph is different for the paragraph's default writing direction or when the text direction cannot be automatically determined. For example, to make sure that phone numbers written with Western digits are displayed correctly in paragraphs of right-to-left Arabic text, select the phone numbers and choose Left To Right from the pull-down menu of the Text Direction button.
  To select the digit style of the text you type into a field, use the Arabic-Indic Digits button. This button toggles digit style from Arabic-Indic to Western and applies only to form fields with an Arabic-Indic default digit style. Using this button doesn't change the digits already in the text.
• Form Field Text Properties dialog box--In this dialog box, there are two tabs: Font and Paragraph.
  In the Font tab, you select paragraph direction using the Auto, Left To Right, and Right To Left radio buttons and you select the digit style using the Digits pull-down menus. Paragraph direction applies to the currently selected text. Digit style applies only to new digits, but not to existing digits.
  In the Paragraph tab, the paragraph direction radio buttons change the paragraph direction of all the paragraphs in the field and not just the direction of the currently selected text.
• Context menus--You can use context menus to change paragraph direction and digits.
• Configure Signature Appearance dialog box--This dialog box contains controls for specifying paragraph direction and digit style. Choosing a paragraph direction also changes the signature appearance. For example, if you set paragraph direction to Right To Left, the Name in the signature filed is placed in the right half of the field and the text is right-aligned and vice versa.

Working with 3D files

If your document has additional usage rights, you can interact with 3D models created in professional 3D CAD (Computer Aided Design) or 3D modeling programs. After you click a 3D model to activate it, you use the 3D toolbar to zoom in and out, rotate, and pan across the object. Use the Model Tree to hide or isolate parts, or make parts transparent.

When a PDF document with a 3D model is displayed in a browser, you can interact with 3D model using IE 5.5, 6.0, 6.0 SP1, or newer; Netscape 7.1 or newer; FireFox 1.0 or newer; and, Mozilla 1.7 or newer.

To show or hide the 3D Toolbar:

Right-click the 3D model, and choose Show Toolbar or Hide Toolbar.

You can also hide the 3D toolbar by disabling the 3D model by right-clicking the 3D model, and then choosing Disable 3D.

To use the 3D navigation tools:

When you navigate in 3D, it helps to think that you are viewing the stationary 3D model from a camera's perspective. You can rotate, pan (move up, down, or side-to-side), and zoom in or out. If the 3D toolbar doesn't appear, you may need to enable the 3D content by clicking in the 3D canvas area with the Hand tool.

Rotate. Orbits around objects in a scene. You can also rotate an object using the Hand tool if Enable 3D Selection For The Hand Tool is selected in 3D section of the Preferences dialog box.

Pan. Moves up, down, or from side to side. When the Hand tool is selected, hold down Ctrl (Windows) or Command (Mac OS) to pan the object.

Walk. Lets you go in any direction. It helps to think that you are the "camera," and the 3D model is a stationary object in front of you.

Zoom. Moves toward, or away from, objects in the scene. When the Hand tool is selected, hold down Shift to zoom in or out.

Distance Tool. Measures parts of the 3D model.

Default View. Returns to the original appearance of the 3D model. You can also select a view you've saved from the Views pop-up menu.

Pause/Play. Pauses or plays animation enabled by JavaScript.

To change the rendering mode, lighting and background:

The model rendering mode determines the surface appearance of the 3D model.

Do any of the following:

• To change the rendering style, choose an option from the Model Render Mode pop-up menu. For example, you may want to choose Transparent to see the inside of the 3D model.
• To view an orthographic projection, click the Use Orthographic Projection button. An orthographic projection effectively removes a dimension, preserving the size ratio between objects but giving the 3D model a less realistic appearance.
• To turn lighting on or off or to change lighting, choose an option from the Enable Extra Lighting pop-up menu.
• To change the background color, choose an option from the Background Color pop-up menu. For example, you may want to improve the contrast between the 3D objects and the background.

Using the Model Tree

The Model Tree includes three sections. The top section includes the tree structure of the 3D object. For example, a 3D object depicting a car may have separate groups of objects (called nodes ) for the chassis, engine, and wheels. In the top section of the Model Tree, you can move through the hierarchy and select, isolate, or hide various parts. The middle section of the includes a list of views that you can create. For example, after you isolate and rotate a part, you can save that particular view. After making other transformations, you can simply click the view you created to return the 3D model to the saved state. The bottom section of the Model Tree includes metadata information, if any, about the part; the metadata is not editable.

To view or hide the Model Tree:

1. Click a 3D object to select it.

2. Click the Toggle Model Tree icon on the 3D Toolbar, or click the Model Tree tab on the left side of the window.

In some instances, the author of the PDF document can set up a 3D model so that clicking it automatically displays the Model Tree.

To manipulate parts:

Some 3D models are subdivided into parts. You can use the Model Tree to hide or isolate parts, zoom in to parts, or make parts transparent.

1. In the Model Tree, click the part you want to manipulate.

2. From the Options menu, choose any of the following:

• Model Render Mode changes the surface appearance of the entire 3D model.
• Show All Parts displays the entire 3D model.
• Display Bounding Box displays the box that encloses the 3D model.
• Set Bounding Box Color changes the color of the bounding box. Choose this option, select a color, and then click OK.
• Hide removes the selected part from view. You can also click the Eye icon next to the part to hide that part.
• Isolate displays on the selected part. All other parts are hidden.
• Zoom To Part changes the center focus from the entire 3D model to an individual part. This is especially useful when rotating the part, allowing it to rotate around its own center focus rather than the entire model's.
• Transparent lets you see through the selected part.

Commenting on 3D designs

Comments added to a 3D object are associated with a particular view. If the view is changed--for example, if the 3D object is rotated or moved--the comments are no longer visible. If you don't want a comment to be associated with a 3D view, add the comment outside the 3D object area. When the view of a 3D object is changed, any comment associated with that object disappears.

To add comments to a 3D object:

1. Select a tool from the Commenting or Drawing Markups toolbar. (The Text Edit tools have no effect on 3D objects.)

2. Add a comment to the 3D object area.

When you add a comment, a new view is created automatically. If your comment disappears, click this view to see the comment again.

To display comments, click the view in the Model Tree that contains the comment you added, or click the comment in the Comments list. The 3D object returns to the view in which the comment was created.

Creating and managing 3D views

Setting a default (initial) view of a 3D design lets you quickly revert to their starting point at any time as you interact with the model. A default view is different from a poster frame, which determines what the 3D model looks like when it's not active. The list of all available views for the 3D design appears in the Views dropdown menu on the 3D toolbar.

You can also create additional views of the 3D model in Acrobat that you can quickly navigate the 3D content based on the views you'd like to see (such as top, bottom, left, right, inside, outside, exploded, or assembled). A view includes lighting, camera position, rendering mode, the Model Tree state, and transparency and cross section settings. When you add a comment or markup to the 3D model, a view is created automatically. You can link views to bookmarks in the Bookmarks tab, or you can use the Go To 3D View action to link views to buttons and links that you create on the page.

To set a default (or new) view:

1. Click the 3D model to enable it.

2. Use the tools in the 3D toolbar to navigate to the view you want to save.

3. In the Model Tree, click the New View icon.

4. To rename the new view, click the view name in the Model Tree, click it again, and then type a more descriptive name.

To create and manage views:

1. Use the tools in the 3D toolbar to navigate to the location you want.

2. In the 3D toolbar, choose Manage Views from the Views pop-up menu.

3. In the Manage Views dialog box, click New View.

4. Select the view from the list box at the right, and then do any of the following:

• Click Use As Default to specify the view that will appear when the user enables the 3D content.
• Rename the selected view by typing a new name in the text-entry field and clicking Rename.
• Click Move Up or Move Down to move the selected view up or down in the list.
• Click Delete View to remove the view from the list.

To display a view:

Do one of the following:

• From the 3D Toolbar, select the view from the Views pop-up menu.
• In the Model Tree, click the view name.
• To return to the default view, click the Default View icon.

To add a 3D view to a bookmark or link:

1. Right-click the bookmark or link, and choose Properties.

2. Click the Actions tab.

3. From the Select Action menu, select Go To A 3D View, and then click Add.

4. In the Select A 3D View dialog box, select the view you want, click OK, and then click Close.

Applying Cross Sections

Applying a cross section of a 3D model is like cutting it in half and looking inside. Use the Cross Section Controls dialog box to adjust the alignment, offset, and tilt of the cutting plane.

To apply a cross section:

1. Click the Toggle Cross Section icon on the 3D Toolbar to turn on or off the cross section.

2. To change cross section properties, choose Cross Section Properties from the Cross Section pop-up menu on the 3D Toolbar.

3. To change the alignment, select whether the cross section applies to the x, y, or z axis. Click Align To Face to align the camera to the selected axis, moving the view perpendicular to the cutting plane.

4. To change the display settings, do the following:

• Select Show Intersections so that lines indicate where the cutting plane slices the 3D model. Specify a different color, if desired.
• Select Show Cutting Plane to display the transparent field that cuts the 3D model. Specify a different color and opacity, if desired.
• Click Align Camera To Cutting Plane to rotate the 3D model so that it's level with the cross section's cutting plane.

5. To change the position and orientation, do the following:

• Click Flip to reverse the cross section.
• Drag the Offset to determine how much of the 3D model is sliced.
• Drag the two Tilt sliders to determine the angle of the cutting plane.

6. (Optional) Click Save View to create a view that you can return to later.

Measuring 3D objects

You can use the Distance tool to measure the distance, angle, and radius of 3D models added to a PDF document. You can also annotate the measurements by adding comments.

To measure 3D objects:

1. Click a 3D model in a PDF document to enable it.

2. Click the Distance Tool icon on the 3D toolbar, or choose Tools > Measuring > Distance Tool. The 3D Measurement Tool palette appears when you move the pointer over the 3D model.

3. In the 3D Measurement Tool palette, do any of the following:

• Choose an option from the 3D Measure Type menu to determine what kind of data is measured in the 3D Measurement Tool palette.
• To change the scaling ratio (such as 3:2) on the drawing areas, specify the appropriate numbers in the 3D Measurement Tool palette. If desired, change the unit of measurement next to this ratio.
• Select Measurement Markup in the tool palette if you want the lines you draw to appear as an annotation. If desired, type the text that will appear in the annotation. Unless Measurement Markup is selected, the object you draw will disappear when you measure another object or select another tool.
• To ensure precise measurement, make sure that Options > Snap To 3D Content is selected.

4. Measure the 3D model:

• As you drag the pointer over other points and edges, Acrobat 3D displays the measurement between the initial selection and the current position.
• If Measurement Markup is turned on, the first two clicks determine the measurement, and the third click determines the location of the markup. For example, to measure a radius, move the pointer over a circular shape. When a circle appears, double-click the circle, drag the pointer where you want the markup to appear, and click again. To measure a distance, click the first point, then click the second point, and then move the pointer where you want the markup to appear and click again.
• If you begin a measurement and change your mind, right-click and choose Cancel Measurement.
• To delete a measurement markup, select it using the Distance Tool, and then press Delete.

To change 3D preferences:

You can determine whether the 3D Toolbar and Model Tree display by default. You can also specify a default renderer and determine whether animations are allowed.

1. Choose Edit > Preferences, and then click 3D.

2. Specify any of the following, and then click OK.

• Preferred Renderer. The rendering engine affects both performance and quality, so it's important to select the appropriate renderer. Depending on your system, you may want to change your render engine. For Windows XP, you can select DirectX 8, DirectX 9, or Software. For Mac OS 10.3 or later, you can select OpenGL or Software. If you select a DirectX or OpenGL option, all rendering takes place using the graphics chip on the video card. If Software is selected, rendering may take more time, but the performance may be more consistent with the original model's.
• Open Model Tree On 3D Activation. Determines whether the Model Tree is displayed when the 3D model is activated. Choose Use 3D Content's Setting to use whichever setting the author used when adding the 3D model to the PDF document.
• Default Toolbar State. Determines whether the 3D toolbar is displayed or hidden when a 3D model is activated.
• Enable Toggle For 3D Toolbar Control. Displays a button on the 3D model that lets you hide or display the 3D toolbar.
• Enable Double-Sided Rendering. Some model parts have two sides. To save time and space, you can deselect this option to render only the side facing the user. If the user looks inside a part rendered with only one side, the back side would be invisible.
• Enable Camera Animations. Some 3D models include animations enabled by JavaScript. Deselect this option to prevent 3D animation.
• Enable 3D Selection For The Hand Tool. Lets the user select and highlight parts of the 3D model using the Hand Tool. If this option is not selected, use the Object Data Tool (Tools > Object Data > Object Data Tool) to select the object.
• Consolidate 3D Tools On The 3D Toolbar. Selecting this option places the manipulation and navigation tools under the Rotate Tool, thereby shortening the 3D toolbar.
