Its important to use the Raster Design command for this task.While AutoCAD 2017 offers the most efficient method for importing PDF data, it doesnt work with all PDF files.If the PDF file is rasterbased instead of vectorbased, for example, PDF Import is not an option because the necessary vector data doesnt exist in the PDF file.Check out my previous post for tips on identifying vector vs rasterbased PDF files.
If you want to reuse data from a rasterbased PDF file, tracing is your best option. Fortunately, there are tools that make tracing the PDF (and other rasterbased files) much easier. Let me introduce you to AutoCAD Raster Design AutoCAD Raster Design is an application that is built on top of AutoCAD. Prior to using AutoCAD Raster Design, I spent countless hours manually tracing geometry in AutoCAD from attached raster files. Autodesk Raster Design 2017 Free Trial OfAutodesk Raster Design 2017 Trial Of AutoCADI knew there had to be a better way I downloaded a free trial of AutoCAD Raster Design and other products that are available in the Architecture, Engineering, and Construction collection. Autodesk Raster Design 2017 Software For 30After using the trial software for 30 days, I put together a white paper for management to review the many features I used to be more productive. It must have been convincing because Ive been enjoying my subscription with access to AutoCAD Raster Design ever since Theres a wide variety of ways to use the software. Ill share just a few of my favorites to help you more efficiently redraw geometry from a raster-based PDF file. In this example, I am redrawing an architectural background as well as piping and electrical information that is associated with the design Im working on. It can be extremely challenging to redraw a building from an image that is skewed because of a poor-quality scan. Lines that are supposed to be straight are wavy and misaligned. ![]() In the left image below, notice the straight polylines with the misaligned image underneath. On the right image, I have straightened the image lines to align with the polyline using Raster Design. Converting PDF to TIF The Raster Design software will only recognize raster image files as opposed to PDF files. So the first step in this process is to convert the PDF to an image file. It is also important to check the scale of the drawing being redrawn. Take a note of it, you will have the option to specify the correct scale when you insert the image as a reference to the drawing. Referencing the Image to the Drawing Once you have the right file format, launch Raster Design, either from a desktop icon or through the Apps Menu. Or click the tab if the Raster Design Ribbon tab is already loaded within the AutoCAD application youre currently using. Youll see a Raster Tools ribbon tab along with your familiar default AutoCAD ribbon tabs). In this example, well be using just a few of my favorites Use the insert image command located on the Raster Design Ribbon.
