Exercise V1: Setting Options and Creating Basic Vector Objects

In this exercise you learn how to set options for vectorization tools and convert basic raster geometry into vector entities.

The Vectorization Tools settings are contained in three of the tabs on the Raster Design Options dialog box: Raster Entity Detection, VTools General, and VTools Follower.

The basic elements of any drawing include lines, arcs, circles, rectangles, and polylines.

Before doing this exercise, ensure that AutoCAD Raster Design toolset options are set as described in the exercise Exercise A1: Setting AutoCAD Raster Design Toolset Options.

Exercise

1. In the ..\Program Files\Autodesk\ApplicationPlugins\RasterDesign2022.Bundle\Contents\Tutorials\Tutorial6 folder, open the drawing file VTools_02.dwg.

   Access the Raster Design Options Dialog Box

2. To display the Raster Design Options dialog box, click RasterOptions.
3. On the Raster Entity Detection tab, set the Max Jump Length option to 20.

   This setting specifies the maximum length of a gap that AutoCAD Raster Design toolset will tolerate when following a raster polyline. It can be used to jump over labels embedded in the line or to follow non-continuous lines such as dashed lines.

4. On the VTools General tab, ensure that the Removal Method is set to REM.

   This option erases the underlying raster while preserving intersecting raster data. To completely remove all raster data underneath the new entity, you would use the Rub option.

5. Click the Round Values option, click Specified Precision, and set the Length precision to 0.01.

   This setting overrides the AutoCAD precision for distances when creating vectors using single-pick options in vectorization tools. However, if you are manually selecting the dimensions, (multi-picking), the chosen points take precedence and the dimensions of the new entity use the AutoCAD precision.

6. On the VTools Follower tab, click End Current Polyline If Closed Loop Detected.

   This option causes new vector polyline entities to finish when a closed boundary or loop is encountered.

7. Click OK to close the Raster Design Options dialog box.

   Convert a raster circle to a vector using a single pick

8. To create a new circle, click Raster menu Vectorization ToolsCircle.
9. Click a point anywhere on the edge of the circle.
   

   Verify the circle properties

10. Enter r to enter a new radius for the circle.
11. Enter 1.75 for the new radius.

    This forces the new vector circle to match the labeled dimension (3.5 diameter).

12. Press Enter to exit the command.

    The command removes the raster data below the new circle, but preserves the intersecting raster dimension lines.

    

    Set a raster snap

13. To set a running raster snap, click RasterRaster Snap.
14. Select Raster Snap On, then click Clear All.

    This activates the raster snaps, and clears the default selections. Raster snaps select points on raster geometry in the same way an OSNAP selects points on vector geometry.

15. Select Corner, then click OK.

    This sets the raster snaps to select a corner where two raster lines connect.

    Convert a raster line to a vector using two picks

16. To create a new line, click Raster menu Vectorization ToolsLine.
17. Enter 2p to draw the line by selecting two points.
18. Select the lower left corner of the base of the part, then the lower right corner.
    

    Verify the line properties

19. Enter l (Length) to change the length of the line.
20. Enter 13.3 for the new length.

    This forces the new vector line to match the labeled dimension.

21. Enter a (Angle) to change the direction of the line.
22. Enter 0 for the new angle.

    This forces the new vector line to be orthogonal.

23. Press Enter to exit the command.

    The command removes the raster information below the new line.

    
24. Close the drawing without saving changes.
