[. . . ] The multi-pick method vectorizes any raster line that you define by clicking a start point and an endpoint. After you select the first start point, you are Vectorizing Raster Lines and Polylines | 207 prompted to enter subsequent endpoints to create a single polyline with multiple segments. After you select a raster line to vectorize, the AutoCAD command line displays a number of choices. You can select another entity to vectorize using the one-pick method, or you can use any of the following options on the vector line segment you just created: 2P, to select another entity using the multi-pick method. You can enter an angular value, or match the angle of another vector line. You can enter a length value, or match the length of another vector line. Undo, to remove the line. If you used the one-pick method to select the raster line, the following options are available to modify the vector line segment you just created: Start, to change the start point. Switch, to reverse the direction, moving the start point to the other end. Trim, to shorten the line by clicking an intersecting vector entity to trim to, or by clicking another entity that, if extended, would intersect the line you are trimming. Extend, to lengthen the line by clicking an intersecting vector entity to extend to, or by clicking another entity that, if extended, would intersect the raster line you are extending. ProdNameShort moves the endpoint to the apparent intersection. NOTE To make the most efficient use of vectorization tools, you should adjust the settings on the VTools General (page 362) tab on the Raster Design Options dialog box. TIP Use raster snapping to make picking points on the raster entity you are converting easier. For more information, see Raster Snapping (page 237). 208 | Chapter 8 Converting Raster Entities to Vector To convert a raster line to a vector line or polyline 1 For straight lines, click Image menu Vectorization Tools Line. The following prompt appears: Specify one-pick point or [2P]: NOTE When you use the one-pick method to select the raster entity, ProdNameShort corrects the point you picked according to the current drafting settings or rounding values. 2 Do one of the following: Select a raster line by clicking near the beginning of the line. The endpoint nearest the point you select is considered the start point. Enter 2p, then enter two points to define the raster line you are vectorizing. 3 NOTE You can cancel the selection of a point by typing undo after you pick the point. 4 Select another raster line using the one-pick method, or do one of the following: Enter 2p to select another raster line to vectorize using the multi-pick selection method. Enter a (Angle) to verify the angle of the vector line segment you just created. Enter l (Length) to verify the length of the vector line segment you just created. Enter u (Undo) to remove the last vector line segment you created. If you used the one-pick method to select the raster line, the following options are available: Enter st (Start) to verify the start point of the vector line segment you just created. Click to select a new start point. Vectorizing Raster Lines and Polylines | 209 Enter e (End) to verify the endpoint of the vector line segment you just created. [. . . ] Thumbnails are used in the ProdNameShort Insert Image dialog box, the Histogram dialog box, and the AutoCAD Image Adjust dialog box. Breaks the image data into rectangular, tiled regions for quicker processing. toggle To switch between two options of an electronic device, usually by pressing a single button. Example: The ProdNameShort Toggle command changes the visibility of the image frame. [. . . ]
