Tools and Utilities. Participating in the Customer Involvement Program As a beginner, expert, or someone in between, you can play a key role in helping Autodesk design software to meet your needs and exacting standards. AutoCAD 2008 includes new automated functionality that enables you to contribute to the future development of AutoCAD without doing a thing! When you participate in the Customer Involvement Program, Autodesk automatically collects anonymous information about your system configuration and how you use the software. Periodically, this information will be sent to Autodesk. However, no personal information will be collected and no one will contact you. 6 AUTOCAD 2008 PREVIEW GUIDE Figure 5. Customer Involvement Program. Specifying Hardware Acceleration AutoCAD 2008 includes support for Microsoft® Direct3D® hardware acceleration providing more flexibility for video cards. You can specify Direct3D or OpenGL® hardware acceleration in the Manual Performance Tuning dialog box which is accessible using the 3DCONFIG command. Regardless of which option you select for hardware acceleration, new texture compression enhancements will require less video memory and improve performance when display images and textures. Figure 6. Hardware acceleration. 7 AUTOCAD 2008 PREVIEW GUIDE Figure 10. Redefine drawing block with tool palette block definition When you modify the location of tools on a tool palette, their order is maintained in the tool catalog (unless the catalog file is read-only) as well as in the profile. This enables you to share your tool palettes without having to manually reorganize the tools. The new TPNAVIGATE command enables you to set a tool palette or tool palette group current using the command line interface. Customizing the User Interface The Customize User Interface (CUI) dialog box has been updated, making it more powerful and easier to use. Enhancements to pane headers, borders, splitter bars, buttons, and tool tips make it easier for you to understand and manipulate the controls and data in the CUI dialog box. With the CUI dialog box open, you can drag and drop buttons directly on a toolbar to rearrange or remove them. In addition, you can Copy and Paste or Duplicate CUI elements such as commands, menus, toolbars from within the CUI dialog box. The Command List pane includes a new search tool that enables you to filter command names as you type. You can view the macro associated with a command by simply passing your cursor over the command name and you can drag and drop commands from the Command List directly onto a toolbar. The CUI customization tree enables you to create a new toolbar based on an existing menu. If you drag and drop a menu element to the top level of the Toolbars node, AutoCAD creates a new toolbar; if you drop it onto another toolbar, AutoCAD creates a flyout. A new Dashboard node enables you to customize panels in the AutoCAD Dashboard. Customizing a Dashboard panel is very similar to customizing toolbars, both within the CUI dialog box and on the Dashboard itself. In addition, you can create a new row of tools in a dashboard panel by dragging a toolbar from the Toolbar node to the Dashboard node. When you select a toolbar or dashboard from the customization tree, a preview pane displays a customizable representation of the selected element. You can drag commands from the customization tree or command list directly into the toolbar/panel preview. And you can drag and drop tools in the preview pane to rearrange or 10 AUTOCAD 2008 PREVIEW GUIDE remove them. When you select a tool in the preview pane, the corresponding tool is automatically selected in the customization tree and command list. Likewise, selecting a tool from the customization tree automatically highlights it within the preview pane and the command list. The Button Image pane displays the name of the image file below the icon preview and a tooltip displays the name of each button icon as you pass your cursor over the image. Figure 11. Customize User Interface dialog box. When you access the CUI dialog box by choosing Customize from the right-click menu of a toolbar, tool palette, or dashboard panel, it opens in a simplified state with only the Command List displayed. You can also access the CUI in this simplified state using the new QUICKCUI command. 11 AUTOCAD 2008 PREVIEW GUIDE Drawing Management AutoCAD 2008 offers new and enhanced functionality for managing the data within your drawings as well as for managing externally referenced drawing data. Working with DGN files AutoCAD 2008 enables you to attach Bentley’s MicroStation® V8 DGN files to your AutoCAD drawings and manage them as externally referenced underlays or import DGN data directly into an AutoCAD drawing. You can also export DWG™ files to V8 DGN format. You can use the new DGNATTACH command to attach a DGN file to your AutoCAD drawing as an externally referenced underlay. When you attach a DGN file, it is displayed in the External Reference palette along with other externally referenced files such as images, DWG xrefs, and DWF™ underlays. You can clip the display area of a DGN underlay using the new DGNCLIP command and you can adjust its properties, including contrast, fade, and monochrome, using the Properties palette or through the DGNADJUST command. Figure 12. External References dialog box and Properties palette. You can import V8 DGN data into your AutoCAD session as a new DWG file using the new DGNIMPORT and DGNEXPORT commands. The V8 DGN file format has also been added to the list of supported file types in the IMPORT and EXPORT commands. After selecting a DGN file to import, AutoCAD displays the Import DGN Settings dialog box. Using this dialog box, you can specify how DGN references should import into the AutoCAD drawing. You can choose to ignore external references, translate reference data into the drawing file, or create a DGN underlay. In addition, you 12 AUTOCAD 2008 PREVIEW GUIDE Working with Xref files A new option in the XCLIP command enables you to clip the inverse of a selected boundary. For example, if you select the Invert Clip option and then specify a rectangular boundary, everything within the rectangle is removed from the display. Figure 16. Inverted Xref Clip Working with Blocks Using dynamic blocks is more intuitive with new grip tips! When you hover the cursor over a dynamic block grip, the associated parameter description is displayed as a tooltip. Figure 17. Dynamic Block Grip Tooltips Recovering drawing files Enhanced drawing recover functionality enables you to select a corrupted drawing (DWG) file and automatically run the recover processes on it and all of its xref files. You can access the new recover functionality by selecting Drawing Utilities>Recover drawings and xrefs from the Files menu or by launching the RECOVERALL command. Figure 18. Drawing Recovery. 15 AUTOCAD 2008 PREVIEW GUIDE Managing Layers The Layer Properties Manager and the new Layer panel in the Dashboard offer many enhancements to simplify the process of creating and managing layers. You can easily rearrange the display order of layer properties by dragging and dropping the column headings and you can control which layer properties are displayed by turning them on or off from a right-click menu. A new Customize Layer Columns dialog box, accessible from the right-click menu, enables you to toggle the visibility of multiple columns. Figure 19. Right-click on column headers. A new layer creation option in the Layer Properties Manager enables you to create a new layer that is automatically frozen in all viewports. You can access this option from a button as well as from the right-click menu. Additionally, if you right-click on an existing layer, you can freeze that selected layer in all viewports. The Rename option in the right-click menu is also new in AutoCAD 2008. However, you can still rename an existing layer by pressing F2 or by clicking twice (slowly) on the layer name. 16 AUTOCAD 2008 PREVIEW GUIDE Figure 20. Right-click on existing layer. You can display objects differently in selected layout viewports while retaining their original layer properties in model space and in other layout viewports. With layer property overrides, you no longer need to use tedious and error-prone methods such as duplicating geometry on separate layers or making copies of xrefs. Instead, when working in a viewport, you can use the Layer Properties Manager to set overrides for VP Color, VP Linetype, VP Lineweight, and VP Plotstyle. When a viewport contains overrides, a Viewport Overrides property filter is automatically created and the override properties are indicated with a different background color. You can select the Viewport Overrides filter to view all layers that contain overrides. A right-click menu in the layer list enables you to remove viewport overrides and a new VPLAYEROVERRIDESMODE system variable enables you to temporarily ignore the overrides for viewing or plotting. Figure 21. VP Layer Overrides. The viewport overrides only affect the display of object properties that are set to BYLAYER. You can quickly change object properties including Color, Linetype, Lineweight, Material, and Plotstyle, of selected objects to 17 AUTOCAD 2008 PREVIEW GUIDE Figure 25. Unreconciled Layer Notification. The Layer Properties Manager automatically creates a layer filter for unreconciled layers. You can review the list of unreconciled layers and then manually select and reconcile layers using the Reconcile option from the right-click menu. Figure 26. Unreconciled Layers. The new Layer Panel on the Dashboard acts as a central location for your Layer tools. It includes all of the tools from the Layers toolbar and more! Figure 27. Layer Panel on the Dashboard. You can access the layer Isolation tools from the Layers panel of the Dashboard. The Layer isolate functionality (LAYISO) command includes a new option for you to lock and fade background layers rather than simply hiding them. You can control the amount of fading of using a slide bar or with the new LAYLOCKFADECTL system variable. Since objects on a locked layer cannot be edited, their grips are not displayed upon selection. 20 AUTOCAD 2008 PREVIEW GUIDE Figure 28. Faded locked layers. Managing Layouts and Sheets AutoCAD 2008 offers many enhancements that make it easier for you to work with drawing layouts and sheets. In-place editing enables you to rename a layout by double-clicking on the layout tab and you can drag and drop layouts to reorder them. Use familiar tools (Ctrl and Shift) to select multiple layouts then and drag them to their new location. If you press Ctrl as you drag and drop the layouts, AutoCAD will create copies or the layouts rather than moving them. Figure 29. Drag and drop to move or copy layouts If you are using sheet sets, you can easily add a layout from the current drawing to the active sheet set. Right click over the layout tab and select the new Import Layout as Sheet option from the right click menu or simply drag and drop the layout tab onto the sheet list. Using either of these methods will display the Import Layouts as Sheets dialog box listing all the layouts in the drawing, with the specified layout already selected. You can easily select additional layouts to import without having to access the right-click menu or drag and drop for each layout. 21 AUTOCAD 2008 PREVIEW GUIDE Figure 30. Import layouts from a drawing into the current sheet set. A new option in the right-click menu of the Sheet List tab enables you to publish your sheet set in reverse order. When this option is enabled, the sheets that you plot using Publish to Plotter or Publish using Page Setup Override will plot in reverse of how they are listed in the sheet set manager. Figure 31. Publish in Reverse Order. Two additional enhancements provide greater flexibility when plotting from the Sheet Set Manager. When using the Publish using Page Setup Override option to create a DWF file, it will honor the Sheet Set Publish Options enabling you to publish to a multi-sheet DWF file. Also, a new system variable, PUBLISHCOLLATE, allows you to disable homogeneous plotting when you publish using Page Setup Override option. Disabling homogeneous plotting allows plots from other drawings or sheet sets to enter the plot spool. 22 AUTOCAD 2008 PREVIEW GUIDE In addition to applying the annotative property on a per-object basis, you can create annotative styles. The Annotative option has been added to the Text Style, Dimension Style, and Multileader Style dialog boxes. If the Annotative option is enabled for a style, that style name will be preceded by an Annotative icon helping you identify which styles are annotative when viewing them in a style list. The annotative object property is automatically enabled for objects, including Text, MTEXT, Dimensions, Tolerance, Leaders, Multiple Leaders, which use an annotative style. However, you can override the annotative property on a per-object basis using the Properties Window. Figure 34. Annotative Styles. When you redefine a style or definition to be annotative or non-annotative, existing objects that reference that style or definition are not automatically updated to reflect the annotative property of the style or definition. Instead, a new ANNOUPDATE command enables you to update the annotative properties of selected objects to match those of the object’s style or definition. When you enable the Annotative property for an object, the object automatically takes on the current annotation scale and a cursor icon indicates that the object is annotative. Once the Annotative property has been enabled for an object, you can add as many annotative scales as you want. However, to optimize the drawing file and performance, you should only add scales that are necessary. It is most helpful to consider at what scale you will represent the drawing and then set that as the current annotation scale when you create new annotative objects. This process will enable you to quickly create annotative objects that are size appropriate and it will minimize the number of additional annotative scales you need to create. For example, if you know a drawing will need to be displayed at ¼”=1’ and ½”=1’, you can set the current Annotation Scale to ¼”=1’ before creating the annotative objects. The new annotative objects will automatically include the scale ¼”=1’. You can then edit the annotative objects to add the ½”=1’ scale. You add or remove the annotative scales using the Annotation Object Scale dialog box, which is accessible from the Properties window or from the right-click menu for a selected annotative object. You can also access it box using the OBJECTSCALE command. 25 AUTOCAD 2008 PREVIEW GUIDE Figure 35. Annotative Scales. AutoCAD automatically creates a representation of the annotative object for each of the specified scales. When you select the object, you can see the multiple scale representations. If you prefer not to see all the supported scale representations when the objects is selected, you can use the SELECTIONANNODISPLAY to display only the current representation. The current scale representation, the one AutoCAD displays even when the object is not selected, depends on the annotation scale of the current viewport (or modelspace). For example, if the annotation scale of the current viewport is 1:4, the 1:4 scale representation of the annotative object is displayed. You can select and grip-edit the current scale representation without affecting the other scale representations. You can easily restore the scale representations of selected objects to their default positions using the ANNORESET command. Figure 36. Annotative Scale Representations. New controls on the status bar enable you to control the annotative scale of the current viewport (or modelspace). When you select or activate a viewport, the status bar includes two scale lists; VP Scale and Annotation Scale. These scale lists are inaccessible if the viewport is locked. However, a Lock/Unlock Viewport button enables you to quickly toggle viewport locking on or off. The VP Scale and Annotation Scale lists display the same set of scales that you will find in other locations in AutoCAD including the Plot dialog box and the Viewports toolbar. You can add or remove the scales displayed in these scale lists using the Edit Scale List dialog box, which is accessible using the SCALELISTEDIT command or by selecting Custom from the list of scales. The scales list is now stored in the drawing file so it can vary per drawing. When drawing files are externally referenced, any named scales (referenced by annotative objects in the xref file) that do not appear in the host drawing are temporarily added to the scales list. 26 AUTOCAD 2008 PREVIEW GUIDE Figure 37. Scale List. When you specify an Annotation Scale, the corresponding Viewport Scale is automatically applied and the annotative objects for the selected scale are displayed using their appropriate scale representations. Any annotative objects that do not contain a scale representation for the specified annotation scale are not displayed. However, you can use the Annotation Visibility button (ANNOALLVISIBLE system variable) to display annotative objects for all scales even if they are not supported by the viewport’s current annotation scale. To avoid having annotative objects “disappear” when you change the annotation scale to a value that is not supported by those particular objects, you can enable the Automatically Add Scales to Annotative Objects When the Annotation Scale Changes status bar option (ANNOAUTOSCALE system variable). Lock/Unlock Viewport Viewport Scale Automatically Add Scales to Annotative Objects When the Annotation Scale Changes Annotation Scale Annotation Visibility Figure 38. Annotation Controls on the Status Bar. When you select a scale from either the VP Scale or the Annotation Scale list, the other scale (VP or Annotation) will update to match. The viewport will zoom to the appropriate scale factor and the appropriate scale representations of annotative objects will be displayed. If the viewport is not locked and you zoom rather than setting the viewport scale, the Annotation Scale doesn’t change and the current scale representations remain visible. The VP Scale, however, changes to display the actual scale of the viewport based on the zoom. In addition to the annotation scaling tools on the status bar, several tools have been included on the new Annotation Scaling panel of the Dashboard. Using these tools you can add or delete the current annotation scale from selected objects as well as access the Annotation Object Scale dialog box. 27 AUTOCAD 2008 PREVIEW GUIDE Figure 43. MultiLeader Style Manager. Overrides for some of the multiple leader properties are available from the Options selection when creating a multiple leader. And you can use the Properties window to modify properties of existing multiple leaders. Additional tools, available from the Dashboard or right-click menu enable you to add or remove leader lines; creating a single leader object that points to multiple locations in the drawing! And, you can easily grip-edit different parts of the leader while maintaining associativity between the leader and text. Figure 44. Multileader with multiple leader lines. The Multiple Leader Align tool (MLEADERALIGN command) and enables you to quickly align a set of leaders along a line and you can control the spacing between them. Figure 45. Multiple Leaders before and after aligning. 30 AUTOCAD 2008 PREVIEW GUIDE Using the Multileader Collect tool (MLEADERCOLLECT command), you can combine multiple block–type multiple leaders into a single multiple leader with multiple blocks. Figure 46. Collected Multiple Leaders. Working with Text The MTEXT Editor has been updated in AutoCAD 2008; providing more flexibility and control over your text. And, the new Text panel on the Dashboard provides easy access to text-related tools including multline text, single line text, Find, Spell Check, text styles and text height. Figure 47. Text Panel on the Dashboard. When creating or editing multiline text, new controls in the Text Formatting toolbar, provide more formatting options for your MTEXT objects. Figure 48. Text Formatting toolbar. New column controls enable you to wrap an MTEXT object across multiple columns. You can specify dynamic or static columns and adjust the number of columns as well as the column and gutter width and height. Grips and the text formatting ruler provide visual editing options. 31 AUTOCAD 2008 PREVIEW GUIDE Figure 49. Column controls. A new Paragraph dialog box enables you to specify tabs and indents as well as paragraph alignment and spacing. Figure 50. Paragraph dialog box. Spell checking has been enhanced in AutoCAD 2008 to further automate the spell checking process. When you launch the spell checker, the Check Spelling dialog box is immediately displayed without first requiring you to select objects. The Check Spelling dialog box has a new drop-down list from which you can choose where AutoCAD should check for spelling errors. The default is to check the entire drawing enabling you to simply choose Start to begin checking the entire drawing for spelling errors. Alternatively, you can choose to check only the current space/layout or specific objects that you select. When AutoCAD detects a spelling error, it automatically highlights and zooms to the word in the drawing. 32 AUTOCAD 2008 PREVIEW GUIDE Creating Dimensions AutoCAD 2008 offers new and enhanced dimensioning functionality, which includes automatic alignment options, dimension breaks, jogged dimensions, text placement, and tolerances. The new Dimension panel on the Dashboard provides easy access to the many dimensioning tools. Figure 55. Dimension Panel on the Dashboard. The new Dimension Break tool (DIMBREAK command) enables you to break dimension or extension lines where they intersect geometric objects or other dimensions. After specifying the dimension that you want to break, you can select intersecting objects to use as cutting edges or you can choose the Auto or Manual options. When you break a dimension by selecting objects or using the Auto option, the breaks will automatically update when the intersection point moves. If the objects are moved so that they no longer intersect, the break will disappear and if they are moved back the break will automatically return to the proper location. The Manual option enables you to specify start and end point of the break. You can use the Restore option to remove all the breaks from selected dimensions or leaders. Figure 56. Dimension breaks. A new Inspection Dimension tool (DIMINSPECT command) enables you to create inspection dimensions, typically used to indicate critical operating tolerances, from existing dimension objects. You can add or remove inspection dimensions and control their appearance including the shape, label and inspection rate. After you convert a dimension to an inspection dimension, you can edit the inspection dimension properties using the Inspection Dimensions dialog box or the Properties window. 35 AUTOCAD 2008 PREVIEW GUIDE Figure 57. Inspection Dimension dialog box. You can add a jog to linear dimensions to represent measurements whose values are not the same length as the dimension line. Jogged dimension lines are typically used when a sheet is too small to display the true length of a dimension line. Using the Dimension Jog tool (DIMJOGLINE command), you can select the dimension and indicate where you want to place the jog. You can edit the jog location using grips and you can turn off the jog or edit its height using the Properties window. Additionally, a new option for linear jog size is included on the Symbols and Arrows tab of the Dimension Style dialog box. Figure 58. Jogged Linear Dimensions The new Dimension Space tool (DIMSPACE command) enables you to evenly space selected dimensions. You can specify the spacing distance between dimension lines or let AutoCAD automatically determine a minimum spacing distance. 36 AUTOCAD 2008 PREVIEW GUIDE Figure 59. Dimension Spacing Enhancements to diametric, radial, and jogged radial dimensions enable you to dimension an arc beyond its endpoints. The process for creating these dimensions hasn’t changed. However, when you specify the location of the dimension line, you can drag beyond the endpoints of the arc. AutoCAD will automatically create an arc extension line using the same properties, such as extension line color and extension line offset, as traditional extension lines. Figure 60. Arc Extension Lines A new option for angular dimensions enables you to place the dimension text outside of the angle being measured. You can access the new option, Quadrant, from the right-click menu when prompted to specify the dimension arc line location. The Quadrant option asks you to specify the quadrant (angle) that you want to dimension separate from specifying the dimension arc line location. If the dimension arc line location that you specify is outside of the quadrant that is being measured, AutoCAD will automatically create an arc extension line to the dimension text. Figure 61. Angular dimensions with and without the quadrant option. The Tolerances tab of the Dimension Style dialog box has been updated to include controls for aligning tolerances. You can align stacked tolerances using either the decimal separator or the operation symbol. 37 AUTOCAD 2008 PREVIEW GUIDE Figure 65. Excel data links. You can edit, rename, delete and preview existing data links using the Data Link Manager. When you create a new data link or edit an existing one, an expandable dialog box enables you to customize the data link settings. For example, you might specify that the cell contents from the AutoCAD table can be written back to the source file. Figure 66. Modify Excel Data Link. When you create a table from a data link, the data is read directly from the linked file. If the data in the linked file changes, a bubble notification automatically displays and a link within the bubble enables you to quickly update the AutoCAD table to reflect changes from the linked file. 40 AUTOCAD 2008 PREVIEW GUIDE Figure 67. Data link notification bubble. The linked cells in the AutoCAD table are locked to prevent editing from within AutoCAD and the range of linked cells is indicated by green corner brackets. If you select a linked cell, its status is indicated by the locked and linked icons as well as by information in the tool tip. Figure 68. Linked Table Cells. Although linked data cells are initially locked, you can add columns and rows to the AutoCAD table enabling you to enter additional data. The changes you make to the AutoCAD table will be retained even after you update the table to reflect changes from the external file. If you want to data in linked table cells, you can unlock selected cells using the Cell Locking option on the right-click menu. When a cell is unlocked, you can edit its contents and even write the new values back to the original spreadsheet. Additional right-click options enable you to update the data link, open the linked file, or detach the data link. If you detach the data link, the table data becomes static and the AutoCAD table behaves just as it would if you had started with an empty table and entered the cell data manually. Figure 69. Table cell right-click menu options. The third option in the Insert Table dialog box enables you to automatically create an AutoCAD table from object data in the drawing. Selecting this option launches the Data Extraction Wizard (DATAEXTRACTION command). Using the Data Extraction Wizard, you can specify the type of data to extract, including objects specific data such as the length of lines and then refine the extracted data based on multiple sorting options. 41 AUTOCAD 2008 PREVIEW GUIDE For example, if you use lines and arcs to represent the gas, drainage, and water lines on a subdivision layout, you might want to extract the length property of all the lines and arcs on the Gas, Drainage, and Water layers. Figure 70. Object Data Extraction. Depending on the type of data you extract and how you wish to use it, you may choose to export the data to an Excel spreadsheet for further calculations. You can also link data from an Excel spreadsheet into your data extraction table. For example, your drawing might include blocks that represent various manufactured parts. Using data extraction, you can extract the item number and quantity count from the drawing blocks and then link the corresponding item number, cost and description from an Excel spreadsheet. The process for linking an Excel spreadsheet to extracted data requires you to specify a data link. You can view a list of all the available data links using the External Data Options dialog box. If the list does not yet include an appropriate data link, you can launch the Data Link Manager to create a new one. After selecting a data link, you must specify a data key column from the AutoCAD table that corresponds to a data key column in the external file. In my example, the item number would be the key column. Figure . Data extraction and external data linking. 42 AUTOCAD 2008 PREVIEW GUIDE Visualization Managing Materials The Materials palette has been updated to provide faster, easier access to materials properties. It includes expandable panels, which enable you to view and edit material setting without having to access multiple dialog boxes. Figure 74. Materials palette. In the Material Editor panel, you can specify the type of material and select from a wide range of pre-defined templates. The pre-defined templates include appropriate values, such as shininess, opacity, and translucency, for common materials. Using these templates, you can quickly create realistic materials without being a “materials expert.” 45 AUTOCAD 2008 PREVIEW GUIDE Figure 75. Material Editor Panel. The Maps panel enables you apply diffuse, opacity, and bump maps to a material and you can synchronize any or all of the maps with the material. When the maps are synchronized with the material, any changes you make to the material will automatically apply to the specified maps, saving you time and reducing errors. The list of supported map types has been increased to include more procedural maps, such as Checker and Tiles, enabling you to achieve more realistic results than from texture maps alone. A button next to the Map Type provides access to map-specific properties by replacing the current Materials panels with Map-specific panels. When you finish customizing the map properties, you can easily return to the general Materials panels. Figure 76. Maps Panel and Map-specific panels. 46 AUTOCAD 2008 PREVIEW GUIDE The Advanced Lighting Override panel enables you to adjust material lighting parameters for greater realism. Adjustable overrides include Color Bleed, Indirect Bump, Reflectance, and Transmittance Figure 77. Advanced Lighting Overrides. The Material Offset and Preview panel enables you to preview the material as well as adjust the offset and rotation values. Figure 78. Material Offset and Preview panel. Applying Photometric Data In AutoCAD 2008, you can create realistic rendered images by applying real-world photometric properties to light sources. For example, you can reference the lighting catalog for a specific fixture and then use the candela, lumen, or lux values to adjust the lamp intensity. Photometric properties are accessible from the Command line when you create a new light or from the Properties window when you select an existing light. 47
