The image below shows the completed task and now the “28”s are part of the raster image and can be used in other DWG files.īe sure to SAVE the raster image after making your changes. To do this, click down on the Edit panel and find the command “Merge Vector”Ĭlick this command and follow the prompts. In this case, we are going to merge the CAD text into the raster image. Now you have to decide whether or not you want to incorporate these CAD entities into the raster image, or leave them as CAD vector objects. Notice in the image below we have created 2 AutoCAD Text entities. Now you can use your regular AutoCAD commands such as TEXT or MTEXT to create the needed text strings “28”. The next image shows both “24”s have been removed from the image. (Of course what it’s actually doing is turning those pixels from “White” to “Black”)īelow shows us selecting a rectangular area around the leftmost “24”. This will let you define a rectangular area of a raster image and delete it. Click this, then choose Rectangular Region. Switch to the Raster Tools ribbon and in the Edit panel, you’ll find a Remove drop down. Of course you can’t use the regular ERASE command. The first thing to do is to erase each “24”. In this case, we have an existing scan of a drawing and everything is correct except for the two “24” numbers shown in the table here. Most large format scanners have the ability to scan to this mode. But if you have a raster image in your DWG file, why not use the tools that are sitting right there? Can you do this with simple tools such as Windows Paint, or even more complex tools such as PhotoShop? Probably.
Raster image tools how to#
The following is a quick tutorial showing how to remove portions of a raster image and replace it with new data. Raster Design is included with many of the Autodesk Suites, including Building Design Suite, Infrastructure Design Suite, and AutoCAD Design Suite, and it seems to be under utilized.
