![]() The AutoCAD objects will now match the Raster objects in the image ![]() To change the AutoCAD lines back into “Raster” simply select the AutoCAD objects and then right click > select “Merge Vector To Raster Image” Once the edits have been made, you will need to plot the drawing but the AutoCAD lines will look so different from the rest of the image. You may also need to use the Touchup tool to clean up left over pixels… When using this to recognize lines that should meet at their corners, it may not work as precisely as you’d like, but you can clean them up by using FILLET with a ZERO radius. To accept this, hit and the pixelated line will be turned into an AutoCAD line and the pixelated line will be erased. If the line is recognized, a dashed line will appear that has a little yellow arrow (glyph). Place the cursor within a line in the image.On the “Vectorize & Recognize Text” panel, click the “Primitives” drop-down and then select “Line” There are other tools that recognize arcs, circles, polylines and rectangles. In the example below I only show how to use the tool that recognizes lines. To exit the Touchup tool, use the buttons on the toolbar to CANCEL or OK to accept the edits.ĬONVERT PIXELATED LINES TO VECTOR LINES – This allows you to make edits with your familiar AutoCAD commands. ![]() This will let you define the size by either dragging a window or by entering a number. The size of the brush can be changed by clicking the button shown below.The angle of the brush is also defined on the 3rd tool from the left.The shape of the brush can be defined by the tools on the left side of the tool bar.Toggle the color of the “Touchup” tool to either black or white by clicking “Toggle drawing color”.For this, the “Touchup” tool allows you to manually erase or draw sections of the image similar to Microsoft Paint allows you to draw with a few pixels at a time. MANUAL TOUCH UP – You may need to manually touch up the drawing. when you are done, the similar sized speckles that are found are highlighted in red and you are prompted to accept the selection set of what it is about to clean up. You can do this by either picking within a speckle or by making a window selection. You are then asked to specify the size of the speckle so that it will look for similar sized speckles and clean them up. So be aware that those may come across as “speckles” and may be cleaned. Note: I did notice that on a few drawings, it erased some periods and commas in text that was in the image. For this example I used I to clean the entire image. You are then asked to specify an area of the image that you wish to clean up. You can easily invert the colors so that the lines are white and the background is your normal AutoCAD background.Ĭlick on the “Cleanup” drop-down > then click “Invert”ĭESPECKLE – The little speckles that are present in the drawing from the image can be easily cleaned up and make your editing look that much cleaner (and easier to edit).Ĭlick the “Cleanup” drop-down and then “Despeckle” INVERT COLORS – Now that the image is in your drawing in black & white, you can change the colors so that you are working in a more familiar color scheme. To make the image “bitonal” click on the “Process Image” drop-down > then click “Change Color Depth” > then B in the command line to choose the “Bitonal” option. Shades of grey or color images simply wont work well in Raster Design. IMAGE TO BITONAL – Many of the tools in Raster Design only work if the image is “bitonal” (black & white). You can scale it by using the SCALE command or by dragging one of its corners to shrink or expand the image. Once the image is in your drawing, you may need to re-position and scale the image to fit your needs. If you want to take the default settings, click “Quick Insert” The 2 shown below are asking how you want to be prompted for various settings while inserting the image. Notice the options at the bottom of the screen. Note: The terminology is a little confusing because usually images are brought into AutoCAD with the ATTACH command and blocks are usually the only things that are “inserted”… The command line version for this tool is IINSERT INSERT AN IMAGE – Using the “Insert…” tool located on the far left of the ribbon, you can navigate to the image that is to be brought into the drawing.
