[. . . ] To turn Dynamic Input on and off, use the AutoCAD system variable DYNMODE, which has four settings: 0 to turn off all Dynamic Input features 1 to turn on pointer input 2 to turn on dimensional input 3 to turn on both pointer and dimensional input See AutoCAD Help for more information on Dynamic Input. Using SmartCorrect This one-pick selection method for Line and Polyline tools vectorizes a raster line with a single click. ProdNameShort automatically corrects the resulting line to conform to current drafting settings. The following sequence of decisions applies: If AutoCAD SNAP is active, the start point and the endpoint are snapped to the grid. If AutoCAD SNAP is inactive but OSNAP is active, ProdNameShort adjusts points that are within the tolerance defined in the Correction Tolerance section on the VTools General tab of the Raster Design Options dialog box. If both ends of the line are osnapped, no further correction is performed. Using SmartCorrect | 205 If OSNAP is inactive, or at least one point was not osnapped, ProdNameShort determines if POLAR or ORTHO snap is active. If so, ProdNameShort aligns the line by moving the endpoint. If one point was snapped earlier, then the free end is automatically considered the endpoint. ProdNameShort adjusts the angle about the start point without changing the length. The angle snap occurs only if the new endpoint falls within the tolerance distance. If Round Values is enabled, the line length is rounded to the precision specified on the VTools General tab of the Raster Design Options dialog box. For more information about adjusting SmartCorrect settings, see General VTool Settings (page 250). Vectorizing Raster Geometry ProdNameShort provides separate vectorization tools to convert raster lines, polylines, rectangles, circles, and arcs. Depending on which raster line type you select, ProdNameShort creates an AutoCAD line or polyline entity with the same position and dimensions as the raster original. 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. ProdNameShort moves the endpoint to the apparent intersection. 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. [. . . ] transparency color A selected color that is transparent in a grayscale or color image. If transparency is turned on for the image, all pixels of the transparency color become transparent. Any time you use a Rub command, the color of the rubbed area is changed to the transparency color. true color (24-bit) image An image that can contain up to 16. 7 million colors. [. . . ]
