You can trace hand-drawn plans in AutoCAD to convert them to digital files. For small businesses in fields like architecture and engineering, these portable digital files allow for how to turn a scanned image into a pdf sending to clients and collaborators, prompting many to import their old paper designs into the program for conversion into digital formats. Although a number of paid applications exist to simplify the process of converting a scanned paper design — if you need the AutoCAD file to exactly represent you paper version — your best bet is still importing the file and tracing over it.
While tedious, this process guarantees accurate and complete conversion. Open AutoCAD and start a new blank drawing. Select “New” from the File menu. Scan your image and save the file as a BMP, JPG, PNG or TIF file. Resave your file into one of these AutoCAD-compatible formats if it is already on your computer. Import the scanned image into AutoCAD.
Type “Imageattach” into the command line or select “Import” from the File Menu. Locate the scanned file on you computer and select it. Check the “Specify on Screen” box to adjust image scale and location in the interface. Click on “Ok” and then move the image around with your mouse until it is located in the center of your screen. Apply a new layer for tracing. Click on the Layers icon in the object properties toolbar or select Layers from the Home menu. Click on “New” in the window and provide a name for your layer.
Select a color that contrasts with the colors in your scanned drawing, make sure the new layer is turned on and click on “Ok” to add the layer. Trace over your scanned image. Use AutoCAD drawing elements like the line, arc, continuous curve or rectangle by clicking on the icons in your drawing menu. Trace over each element in your scanned drawing with these tools, pressing “Enter” after each line or clicking on the line and pressing “Delete” to remove errors.
