Setup Before running the tutorial, several initial setup steps should be carried out. Certain sections of this tutorial take for granted that all previous steps have been completed. Place the demo.cel attachment in the <drive>:\bentley\program\microstation\irasb directory. Setup is a time saving step that enhances the speed at which vectorization can occur. Each drawing will need to have its own customized setup depending upon its nature. Many drawings with standards can use the same setup. Below are steps for this particular drawing and to help the user get familiar with the process. Section I Setting Working Units and View Preferences Start MicroStation I/RAS B using the demo.dgn file located in the Bentley\Program\MicroStation\irasb\Samples directory. 1. Access the Applications pull-down and switch to MicroStation. 2. In the MicroStation pull-down menu, go to Settings > Design File > Working Units. Set working units to FT, IN, 12, 10000 and use File > Save Settings to save the working units 3. Toggle back to the I/RAS B pull-down menu Applications - I/RAS B. 4. Use File > Open and access the Bentley\Program\MicroStation\irasb\Samples directory. Open the file demo.cit on Layer 0, Color 0. Use Raster File Header Transformation. 5. Access View > Fit Active Layer and click once inside all three views to fit. 6. Access Applications > Engineer > Preferences > Views. Enable Views 1, 2, and 3. Then under Setup, choose View 2. Enable Auto Move and Hot Box. To enable Hot Box select the SHOW button. Auto Move automatically shifts the specified view if data points are placed outside of the hot box. The region that causes the view to automatically move is called a hot box. 7. Enable Auto Zoom. Use Window Area to give View 2 a higher zoom level than View 1. Then set Apply for Auto Zoom. Auto Zoom automatically zooms to a user-defined magnification level. This option is only available for line tracing and QTR. MicroStation I/RAS B Engineer Tools Tutorial Workbook 1
8. Enable Auto Update after Raster Separation for View 2. MicroStation I/RAS B 9. Repeat steps 7, 8, and 9 for View 3. Window Area in View 3 giving an even higher zoom factor than View 2. 10. Once these steps are completed, in the View Preferences dialog box, choose the Layout pull down, and use Save As to save the preferences as demo layout. Dismiss the dialog. Different layouts can be saved for diverse types of drawings with different standards. Engineer has the ability to load, delete, save, and display different view preferences based upon the users needs. 11. Access the Quick Zoom dialog by selecting Applications > Engineer > Preferences > Quick Zoom pull-down. 12. Enable Views 2 and 3 and Apply to each View. Dismiss the dialog. 13. Once setup is completed for View Preferences, your screen should look similar to the graphic below: MicroStation I/RAS B Engineer Tools Tutorial Workbook 2
Section II Raster Separation and Snap Parameters MicroStation I/RAS B Raster Separation gives the user the ability to separate the raster (copy, move, delete) from the vector as the vectorization process is occurring. This allows to see what has been completed and has yet to be accomplished during vectorization. 1. Access the Raster Separation dialog by selecting Applications > Engineer > Settings > Raster Separation. 2. Enable Separation. 3. Set the Setup Option to Delete. 4. Enable Set Line Width. Use the button on the far right-hand side of the Line Width dialog to measure half the raster width of a line in View 3. This tells Engineer at what tolerance to search for raster and separate (in this instance delete) during the vectorization process. If this search tolerance is set too low, some of the raster may not be separated. If it is too high, unnecessary raster may be deleted.) 5. Enable the Backfill option and dismiss the dialog box. Using Backfill with raster separation provides the capability to reconstruct converted raster items that were deleted or moved during the raster separation process and which intersect raster items not yet converted.) 6. Access the Raster Snap dialog by selecting Applications > Engineer > Settings > Raster Snap. 7. Set Snap Mode to Dynamic. Enable Center, End of Line, Intersection, and Corner. Setup the colors respectively (Center = red (3), End of Line = blue (1), Intersection = green (2), Corner = yellow (4). Dismiss the dialog box. Dynamic Raster Snap allows users to find snap points, based on the colors they specified, without having to zoom in and out of the drawing. This speeds up the vectorization process. 8. Access the Vector Snap dialog by selecting Applications > Engineer > Settings > Vector Snap. Choose Snap To Existing Elements and dismiss the dialog. Section III Setting Up Line Terminators In this section, we will convert line terminators in order to speed up the conversion process. This section explains how to setup these parameters. MicroStation I/RAS B Engineer Tools Tutorial Workbook 3
Users should determine if these items will be required when vectorizing their own drawings and organize their setup as needed. 1. Access the Line Terminators dialog by selecting Applications > Engineer > Settings > Line Terminators. Set the Option to Single. 2. Under Select Terminator Library, choose archpa.cel. Set the Active Terminator to LT1. Dismiss all dialogs. Section IV Toggles The Toggles dialog allows quicker access to a few important Engineer commands. Keeping this dialog box open during a session can speed up the overall vectorization process. 1. Access the Toggles dialog by selecting Applications > Engineer > Settings > Toggles. Review the Toggles dialog box. Notice Line Terminators, Raster Separation, Raster Snap, and Vector Snap are all enabled now that Setup has been completed for each function. 2. Access the Line Terminators dialog by selecting Applications > Engineer > Settings > Line Terminators. Use the Toggle dialog to disable Line Terminators. Notice on the Line Terminators dialog that the terminator changes from Single to Off. During a vectorization process, you can easily turn line terminators off and on as needed simply by using the Toggle dialog. 3. Access the Raster Snap dialog by selecting Applications > Engineer > Settings > Raster Snap. Use the Toggle dialog to disable Raster Snap. Notice on the Raster Snap dialog that the snap can be toggled from Off to Dynamic. During a vectorization process, you can easily turn raster snap off and on as needed simply by using the Toggle dialog. While Dynamic Raster Snap is very useful for vectorization, occasionally, turning snap mode off may be required. For instance, vectorizing circles by one point can occasionally benefit from having raster snap turned off since there are no intersections, corners or end of line to find in a raster circle. 4. Keep the Toggles dialog displayed on screen for use during the rest of the tutorial. Dismiss all other dialogs. Section V Understanding and Using Quick Zoom 1. Access the Quick Zoom dialog by selecting Applications > Engineer > MicroStation I/RAS B Engineer Tools Tutorial Workbook 4
Palettes > Quick Zoom. 2. Place the Quick Zoom dialog somewhere between View 2 and View 3 for easy access during the rest of the tutorial. Quick Zoom will allow easy access to specific raster data during the vectorization process without having to interrupt the workflow by zooming in and out. Engineer s Quick Zoom also stays in the specified command being used which alleviates having to place extra data points to access commands, thus further enhancing the vectorization flow. MicroStation I/RAS B Engineer Tools Tutorial Workbook 5
Tutorial I Vectorizing Data Now that you are familiar with the Setup process for Engineer, it is time to start vectorizing data! Below are steps that will further demonstrate Engineer s vectorization capabilities. If Setup has been completed correctly, View 1 should be a full view of demo.cit. View 2 should have a higher zoom factor than View 1 and View 3 s zoom factor should be high enough to see the raster data very clearly. At this point, we will be using the Engineer palette menu to further familiarize the user with the commands. The Engineer palette menu can be recognized by the I/RAS... at the top of the palette. I/RAS B s palette menus both have I/RAS B at the top. Keep the I/RAS B palettes docked, but tear off the Engineer palette menu. Converting Circles, Lines and Arrowheads 1. Choose the I RAS/E Convert Circle Point command. This command is third from the top on the left-hand side of the palette menu. 2. In the Toggles dialog, verify that Raster Snap is disabled. 3. In View 1, on the bottom right-hand side of demo.cit, locate a section of four circles directly on top of each other. (See Diagram below) Use Quick Zoom and enter a data point as close to the bottom circle as possible. Views 2 and 3 should jump to this circle. Reset and vectorize your first circle. MicroStation I/RAS B Engineer Tools Tutorial Workbook 6
4. Use Quick Zoom in View 2 and pan left to locate the circle labeled 29. Reset and continue vectorizing all other circles to the right ending with the circle labeled 38. If the views are setup correctly, as you vectorize circles, Auto Zoom and the hot box area defined should move you to the next circle. You can also use the Quick Zoom button to pan in View 3 to find more circles. Once you have found the next circle using Quick Zoom, a simple reset will return you to the Convert Circle Point command to continue vectorizing.) 5. Once all circles are converted, enable Raster Snap by toggling to Dynamic using the Toggles dialog. Run your cursor over the raster file in any view. Notice how the cursor and colors identify raster segments based on the colors defined for Dynamic Raster Snap. MicroStation I/RAS B Engineer Tools Tutorial Workbook 7
6. Choose the I RAS/E Convert Two Point Line command. This command is first from the top left-hand side of the palette menu. If you converted the circle labeled 38, you should be able to run your cursor close to the end of the line segment protruding from the circle. We are going to convert this line and arrowhead, as well as the lines and arrowheads protruding from the other circles we vectorized. 7. Convert the line string protruding from the circles just converted. Use Quick Zoom to pan to the end of the line if needed. If Quick Zoom is used, a simple reset will place you back in the Convert Two Point Line command, enabling you to find the end of the line. Line Terminators are set up and toggled to ON, so a line terminator should appear at the end of each line. Notice the blue cursor point that appears at the end of each line. Since End Of Line was set to the color blue in the Raster Snap dialog, you will be able to find the end of each line for conversion easily regardless of what view you use. 8. The final process should work easily following these steps: a. Use View 2 to find the end of the line indicated by the blue cursor. b. Use Quick Zoom to pan to the other end of this line in View 3. c. Reset. d. Place end of line with terminator, then enter a data point. e. Repeat steps a through d. MicroStation I/RAS B Engineer Tools Tutorial Workbook 8
9. After vectorizing all lines with terminators, use the Toggles dialog box to disable line terminators. Getting familiar with QTR (Queued Text Replacement) Once all the circles, lines, and terminators have been placed, you get familiar with QTR or Queued Text Replacement. What is QTR? Queued Text Replacement is a dual process that: Locates pixel groupings that potentially represent text. Presents the groupings in a queued environment for you to overlay with vector text elements. You define the size parameters for detecting the pixel clusters. You also define the proximity distance parameter for grouping the pixel clusters into character parameters. You can set the minimum, maximum and proximity distance measurements in two ways: Click the Text Size Measure button to measure the text size. Or Type a value in the Text Size field. MicroStation I/RAS B Engineer Tools Tutorial Workbook 9
1. Access QTR from the palette menu. It is the fourth button from the top on the left-hand side of the menu. Accessing this button brings up the QTR Edit dialog box. 2. On the QTR Edit dialog, select the QTR Process button. This brings up a larger QTR Process dialog box. 3. Using the numbers inside the circles you just vectorized, start measuring for QTR. Use Quick Zoom to enter a data point near the circle labeled 52. View 3 should zoom in close enough to allow you to measure the text. 4. Use the measure buttons on the large QTR Process dialog to measure the minimum text size, the maximum text size, and the proximity distance for the number 52. In this instance, for minimum text size, measure approximately a third of the numeral 5. Minimum Text size: If you choose to measure a character to determine the minimum size, a good starting point is to measure three-fourths of the width of the smallest character (such as a period) in your data. Maximum Text size: If you choose to measure a character to determine the maximum size, a good starting point is to measure diagonally across the largest character that you want to be queued in the section of text to be processed. Proximity Distance: If you choose to measure the proximity distance, a good starting point is to measure from a point one quarter of the way into one character to a point one quarter of the way into the next character. Recognition Options: Enables you to specify how text is presented and to select drawing types. The Text Recognition toggle turns recognition on and off, and the Drawing Type list box displays a list of files containing predefined recognition parameters. 5. Enable Text Recognition options. 6. Under Drawing Type choose Good qual num and up case (good quality numbers and upper case text). 7. Once the sizes have been measured, verify that Process Mode is Fence Rectangular and Orientation is Horizontal. 8. Once measurements have been taken, Engineer prompts you, in the MicroStation I/RAS B Engineer Tools Tutorial Workbook 10
status bar, to place a fence around the text you wish to have queued. Place a fence in View 1. 9. Enter a data point in the upper left-hand corner of the circles you have vectorized and then enter a data point again at the lower right hand corner of the same circles. Place your fence such that the only raster data within the fence are the numbers of the circles you have recently vectorized. 10. Once the fence is placed, QTR processing starts. 11. Wait for the message Process QTR Successfully Completed to appear. Click OK. 12. Then, locate the QTR Edit Start, which is the second button from the left located on the QTR Edit dialog. 13. Next, locate the QTR Edit Settings dialog box and verify the following settings: color = red (3) and weight = 2. 14. The QTR editing process should start. Inside the QTR Edit Text Review dialog, it should start showing the pixel groupings that it has processed. These should reflect the numbers inside the circles. 15. As the numbers appear in the QTR Edit Text Review box, hit Apply if the text is correct. MicroStation I/RAS B Engineer Tools Tutorial Workbook 11
16. If you have queued noise or other items that you do not wish convert, you can hit the Skip button and QTR will skip to the next queued item. Normally, this occurs because unrecognizable raster data fell within your fence definition, such as tick marks or small dashed lines. 17. If the text is not correct and QTR has not queued it, you can enter your own text in the QTR Edit Text Review dialog and then hit Apply. 18. If the text is not correct, QTR may show a list of characters it believes falls within the parameters you specified. Choose the correct text from the list if it is present and hit Apply. 19. Continue this process until all text is queued and replaced. Once you reach the end of the queue you will see the following message: End of queue reached. Do you want to continue to the first item? Click Ok to end the process. 20. To stop the QTR processing, locate the QTR Edit dialog box and exit by choosing the last button on the right-hand side of the dialog. The following message should appear: Data has been tentatively placed. Are you sure you want to exit without verifying?. Click OK. MicroStation I/RAS B Engineer Tools Tutorial Workbook 12
21. To stop the QTR process completely, click the QTR Exit button in the QTR Edit dialog box. It is the last button on the far right. 22. Dismiss all QTR dialog boxes. Your first QTR process has been completed! The numbers within the circles you vectorized should now all be vectorized as well. Section VI Setting Up Symbology Sets In this section, we will convert symbology sets in order to speed up the conversion process. This section explains how to setup these parameters. Users should determine if these items will be required when vectorizing their own drawings and organize their setup as needed. 1. To create new Symbology Sets select Applications > Engineer > Settings > Symbology Sets, and select New. Symbology Sets allow the user to create linear or text sets based on weight, color, line style, and font, depending upon their specific needs in a drawing. These sets can be saved and used for various drawings. 2. Create a new symbology set called red solid. This set should have the following parameters: Type = Linear Level = 1 Color = red (3) Weight = 2 Line Style = 0 3. Create a second symbology set called green dashed. This set should have the following parameters: Type = Linear Level = 1 Color = green (2) Weight = 2 Line Style = 4 4. Once the symbology sets have been created, dismiss the dialog box. The setup process for Symbology Sets has been completed. MicroStation I/RAS B Engineer Tools Tutorial Workbook 13
Tutorial II Converting Line Strings This section covers converting line strings, as well as using the Symbology Sets you created earlier. 1. Access the Quick Zoom button located between Views 2 and 3. 2. In View 1, locate the part identified by number 7, which is located on the left-hand side of demo.cit, approximately 1/4 of the way up from the bottom. In the graphic below, note that in Window 2, the part we will vectorize is denoted by the line terminator. 3. Enter a data point near the part in View 1. 4. If Quick Zoom and Auto Move were setup correctly, Views 2 and 3 should jump to show this part more clearly. 5. Access the Active Symbology Sets dialog by selecting Applications > Engineer > Palettes > Active Symbology Sets. MicroStation I/RAS B Engineer Tools Tutorial Workbook 14
6. Choose red solid as the active set and dismiss the dialog. MicroStation I/RAS B 7. On the palette menu, first button from top on left should be the IRASE Convert Two Point Line command. If you click on the command and hold the button down, several other buttons will appear. Choose the IRASE Trace LineString command which is the fourth button over to the right. 8. On the Trace LineString command, you will be going Straight at Raster Intersections and Snap To Existing Vector Lines. 9. Enable Gap Connections and choose Setup. Under Setup set the Distance to 0.045 ft and the Angle to 0.18 degrees. Dismiss this dialog. 10. Enable Smooth and Filter and set the option to Smooth and Filter. Choose Setup, and set Smooth to 0.00015 ft, and Filter to 0.00015 ft. Dismiss this dialog. 11. If you are no longer in the Trace LineString command, select the command again. Enter a data point on the bottom section of the part identified by number 7. The line string should be traced in one direction. In the MicroStation command window it should prompt you: <D> to enter point/<r> to end this direction 12. Hit Reset to end this direction and trace in the opposite direction. Then reset again. 13. Do the same for the upper section of the part identified by number 7. The part should be traced, vectorized and raster separated (deleted). MicroStation I/RAS B Engineer Tools Tutorial Workbook 15
14. Access the Active Symbology Sets dialog by selecting Applications > Engineer > Palettes > Active Symbology Sets. 15. Choose green dashed as the active set and dismiss the dialog. 16. Using Trace Ling String, trace the line in the very center of the part number 7 you just vectorized. You may have to choose the command again before entering another data point. Notice the difference in the lines created with each symbology set. Dismiss all dialog boxes except the Toggles dialog. Section VII Setting Up Cell Libraries In this section, we will convert cells using existing cell libraries. This section explains how to setup these parameters. Users should determine if these items will be required when vectorizing their own drawings and organize their setup as needed. 1. Access the Cell Library dialog by selecting Applications > Engineer > Settings > Cell Library. Navigate to the Bentley\Program\MicroStation\irasb\Samples directory and choose demo.cel. 2. Enable Cleanup and dismiss the dialog. Cleanup places the cell and automatically deletes the section of the line that intersects the boundary of the cell. MicroStation I/RAS B Engineer Tools Tutorial Workbook 16
Tutorial III Working With Macros Engineer allows you to define and run macros to further speed up the vectorization process. A macro in Engineer is a combination of commands that are executed in a specific sequence to perform digitizing. 1. Above part 7 you just vectorized, use Quick Zoom to locate a string of lines and cells identified by the cell numbered M212SH2. This cell is located on the left-hand side of demo.cit about a quarter of the way up from part 7. Select red solid as the Active Symbology Set. a. Use Quick Zoom to enter a data point in View 1. Views 2 and 3 should jump to a closer magnification into the cell. 2. On the palette menu, choose the IRASE Command Macro. This button is second from the top on the left-hand side. a. The Engineer Command Macro dialog box should appear. b. Choose the Edit button. 3. Under the Engineer Command Macro Builder choose Convert Cell and then Replace. a. Select Convert Two Point Line and then Append. b. Select Convert Cell and then Append. MicroStation I/RAS B Engineer Tools Tutorial Workbook 17
c. Select Convert Line String and then Append. d. Choose Convert Cell Along Line Segment and then Append. e. Click OK to dismiss dialog. 4. Since you will be converting some cells along with line strings, bring up the Active Cells dialog. On the left-hand side of the palette menu, the fifth button from the top will activate this dialog. a. Choose the Select Active Cell button from the IRASE Convert Active Cell dialog box. b. Select the cell labeled RLABEL. 5. Under the Engineer Command Macro dialog box, choose Start. a. Mode should be set to Manual. 6. Place the RLABEL cell. Notice how the next command in the macro automatically starts once this command is done. 7. Next, place the two-point line from the end of the RLABEL cell to the end of this line. Use Quick Zoom to help find the end of the line without having to exit the command. Reset and then place the end of this line. 8. Choose the next Active Cell BLOWER. Place this cell. 9. Use Quick Zoom to zoom back towards the left and find the line string that intersects the two-point line you just converted. Use the Convert Line String command to convert this line string with the cell above it labeled CD29. MicroStation I/RAS B Engineer Tools Tutorial Workbook 18
10. Now, convert the cell CD29 by using the cell labeled BVALVE. a. In the Engineer Command Macro dialog box, select Stop. b. Notice how the intersecting lines within the cell you converted along the line segment are cleaned up. It is generally a good rule of thumb to place all lines, intersected by cells first, in order for the cell cleanup command to work properly. 11. Dismiss all Macro and Active Cell dialogs. MicroStation I/RAS B Engineer Tools Tutorial Workbook 19
Tutorial IV More on QTR As explained previously, Engineer has the ability to capture textual data by using QTR. In this section, the examples include text series that are not high quality data like the numbers you converted earlier. 1. Using Quick Zoom, locate the words BECHTEL and VENDOR directly above the cells and line work you just converted as seen in the following diagram: MicroStation I/RAS B Engineer Tools Tutorial Workbook 20
2. Access the QTR command (fourth button from the top, on the left). 3. Access the QTR Process command (first button from the left on QTR Process dialog). 4. Using what you learned from the previous QTR exercise, take the measurements for minimum height, maximum height and proximity distance for the word VENDOR. Measure the proximity distance between the letters O and R since these characters are the farthest apart in proximity. 5. Place the Fence Rectangle around the word VENDOR while trying not to include any other raster within the fence except the word itself. 6. Once the QTR Process is completed, start the queuing process with the QTR Edit Settings dialog (Second button from left on QTR dialog box). 7. The word VENDOR should be barely recognizable. This is because the Drawing Type is still set to good qual num and up case. The word VENDOR is closer to poor qual num and up case. By defining your Drawing type, Engineer has the ability to aid in capturing your textual data. 8. In the QTR Edit Text Review dialog (as seen above), choose Skip to allow the QTR process to ignore the textual data. 9. Hit OK on the End of queue reached. Do you want to continue to first item? message. 10. In the QTR Edit dialog, end the QTR process. (Last button on far right of dialog). a. Choose OK on the Data has been tentatively placed. Are you sure you wish to exit without verifying? message. 11. Start the QTR process again. You do not need to measure, as the MicroStation I/RAS B Engineer Tools Tutorial Workbook 21
measurements from your previous session should be saved. MicroStation I/RAS B a. This time, under Drawing Type, choose poor qual num and up case. b. Replace your fence around the word VENDOR. c. Once the process is completed, queuing should present more satisfactory results, as seen below: d. Preserve VENDOR in the Alternatives list and hit Apply. e. Choose OK on the There are no more unedited items in the queue. message. f. Exit the QTR process. 12. Start the QTR process again. This time, take measurements for the word BECHTEL in the same manner as you would take them for a word with a horizontal orientation. a. Set the Process Mode to Fence Polygon and Orientation to Vertical. b. After the measurements have been taken, you are prompted to place a fence around the data. Use a polygon fence to carefully fence in the word BECHTEL. c. Once the QTR process has finished, start the queuing process with the QTR Edit Settings dialog. Since the C in BECHTEL is not very clear, Engineer is unable to recognize it as a C, as seen below: MicroStation I/RAS B Engineer Tools Tutorial Workbook 22
d. To alleviate this problem, manually replace the L in BELHTEL with a C for BECHTEL, and hit Apply. 13. Exit the QTR process and notice that the word BECHTEL has been placed at the correct orientation with a minimum amount of effort. MicroStation I/RAS B Engineer Tools Tutorial Workbook 23
Tutorial V Using ITR (Interactive Text Replacement) This section explains how using ITR (Interactive Text Replacement) can help clean up data that may touch linework or data that could be considered poor quality data. With a minimum amount of effort, Engineer will interactively place text that the QTR process is unable to queue because it is handwritten, illegible data or data that touches linework. 1. Use Quick Zoom to locate the cell CD29 directly below the BECHTEL/VENDOR data you just vectorized. 2. Choose the ITR command. This is the fourth button from top, on righthand side of the palette. It is located directly across from the QTR command. 3. On the Engineer ITR Process command dialog box, set the following: Font = 1 Weight = 2 Level = 1 Color = 3 4. Enable Set Text Size. 5. Measure the Text Height from the bottom of the D in CD 29, to the very top of the D. MicroStation I/RAS B Engineer Tools Tutorial Workbook 24
6. Measure the Text Width from the bottom left of the 2 in CD 29, to the bottom right of the 2. 7. Raster Separation should be set to Two Point. 8. On the Toggles dialog box, disable Raster Snap. 9. In the MicroStation Command Window note that the ITR process is prompting you for text. [1] Itr> 10. Key-in the text CD 29. 11. Hit Enter. 12. Select the text origin and place the text as desired. 13. Engineer s ITR command then prompts you to place a fence around the data you just placed in order to process the Raster Separation. Notice the raster below the text you just placed is deleted. 14. Continue this process for the 1 1/2 text to the right of CD 29. Continue this process for the CE2 V13 text located in the cell underneath CD 29. Congratulations! You have finished the MicroStation I/RAS B Tutorial focusing on the Engineer Raster to Vector conversion functionality! Continue to practice all that you have learned from this tutorial to vectorize other areas of demo.cit.

Engineer Commands View Preferences Create and save multiple view layouts. Allows a variety of layouts for different users, workflows, or drawing types. Quick Zoom Command Zoom in to a specific area of the design file. Each view has a preset level of zoom magnification. Re-zoom or return all applied views to the previous zoom levels. MicroStation I/RAS B Engineer Tools Tutorial Workbook 26
Raster Snap Allows snapping to corners, intersections, open symbols, and solid symbols. Dynamic snap visually displays the snap points as the movement of the cursor is tracked. Vector Snap Vector snap is available for the software s conversion commands. Options for snapping include Snap To and Snap To And Break existing vector elements. MicroStation I/RAS B Engineer Tools Tutorial Workbook 27
Raster Backfill Reconstructs or backfills raster intersections where items normally deleted or moved from a raster separation process also intersect raster data not yet converted. Raster conversion with separation is easier and more accurate. With Backfill Without Backfill Convert Circle by One Point Command Convert raster circles with a single data point. Define the actual radius of the circles. MicroStation I/RAS B Engineer Tools Tutorial Workbook 28
Copy Element with Raster Separation Command Copy existing vector elements with raster separation honored. Useful for converting many like raster items sequentially. Copy Parallel Extend Command Copy and place vector lines parallel to the original line and then extend to a user-defined set of boundary vectors. Useful for converting sets of parallel lines that must have a uniform length. MicroStation I/RAS B Engineer Tools Tutorial Workbook 29
Line/Arc Command Trace raster data and convert it into vector lines, arcs, or a combination of lines and arcs. Convert existing complex vector line strings into lines, arcs, or a combination of these elements. Cell Cleanup Clean up existing vector lines to the edge of the cell. Produce cleaner looking transition from line to cell. Before After MicroStation I/RAS B Engineer Tools Tutorial Workbook 30
Convert Cell Along Line Segment Command Place cells in line with existing vector lines regardless of orientation and without additional manipulation. Cell cleanup is honored. Convert Cell Interactive Command Interactively placed cells are first rotated and then scaled. Place and dimension cell operations are more accurate. Rotate Scale QTR/Text Recognition Raster text is automatically recognized. Only requires validation for conversion to MicroStation text strings. Software can be taught to recognize text strings more accurately. Alignment of converted text strings is available. MicroStation I/RAS B Engineer Tools Tutorial Workbook 31
Axis Lock Axis lock can be set while converting with Trace Line String and Line/Arc and is honored by these commands. Clip Lines Command Trim or clip converted lines to a user-defined vector line. Options include clipping all lines or selected lines to a specific side of the clip line. Line Terminator Placement Place single or double ended line terminators automatically. Available for all line conversion commands including Trace Line String and Line/Arc. MicroStation I/RAS B Engineer Tools Tutorial Workbook 32
