In this tutorial I will show you how to import a raster image into AutoCAD and then scale it so that you can begin to trace over the image and create vector line work based on a raster image. You can start by opening on a new file. From the templates I'll choose the A CAD ISO. This should automatically open a blank file which has the units preset to millimeters. I can double check that by clicking on the AutoCAD icon in the upper left corner and then going down to drawing utilities and units. And here we can see our units are set to millimeters. Everything else looks fine as well. Let's say okay. So I'm going to start off by importing my raster image. Click on the insert tab to the top and then go to attach. And then this will ask me to basically navigate to my to my image. Once you find your image you'll get this dialog box which has a few options. In this pane you have a preview of your image. Under Path type you have a few options either full path or relative path or no path. In search and point we can check this and then we can place it wherever we want. We leave it unchecked. It would just place it at the origin 0 0 0. Which is fine. Scale. We don't need to adjust because we would do that once we import the image. Rotation should be fine as well. So we'll just say okay. And then if we zoom out we can see the image here at our origin. The other way we could have imported that is by typing x-ref and hitting enter. And then we get this dialog box. And if you click on this, I told them next to the twg icon which allows you to change to attach image and a few other options as well. So if we attach image we basically get the same options of navigating towards our image. So now we have our image. The first problem is it's quite bright. I can barely see my cursor over top of it. So to fix that I'm going to select the image and AutoCAD automatically switches to the image tab where I can adjust this fader. Basically turn down the contrast in this image allowing me to see my cursor and line work on top of it much easier. So next we will try to figure out how big this image is. We can use this scale here in the bottom of the image. We can go ahead and measure it. typing distance. Click one end of the scale and then click near the other end of the scale. And that says 69.2 millimeters. So that is very small in comparison to what we actually want which is 5 millimeters or 5,000 millimeters. So rather than doing the math and multiplying this image by a specific number we can scale by reference. So what I would do first is create a line of reference. Basically a line that's 5,000 millimeters long or 5 meters long which is what I want this part of the image to be when it's all scaled accurately. So I will get as close to I can to one end of the scale in the image. Then I will draw a line that is 5 meters long or 5,000 millimeters. If I zoom out I enter to complete command. You can see this line represents actually 5 meters. So next all we have to do is scale up this image so that the scale in the image matches the 5 meter long line. So I will select the image and then go back to my home tab at the top. In the modify tools you'll find scale. If I click on that down at the bottom here it's asking me to select my object and I want to scale my image. So I will select the image and hit enter and now the bottom it's asking the bottom it's asking me to specify a base point. That's basically the point around which I want to scale the object. So I will use the starting point of my line and which is also the starting point of the scale in the image. Now I'll click there once and now it's saying specify specify scale factor and then in parentheses it says copy or reference. In those brackets those are my two additional options. I can choose to scale this as a copy which I do not want to do this time or I can scale it with reference which is what I want. So in order to activate one or the other of those commands I could type C for copy or R for reference. So I will type R for reference and hit enter. Now it's asking me for reference length. My reference length is the length of the scale in the drawing. First I will click on end of my scale which is also the base point of my whole scaling operation. Now it's asking for the reference length which is the length of the scale in the raster image. So I will get as close as I can to the other end of this scale and click a second time. Now you'll see it's asking for a new length and the new length is the length of my 5 meter long line. So I will snap to the end of that line and now as you can see my 5 meter long line and my 5 meter scale in the image are exactly the same. And from here I can set up a few layers and then begin to trace over this image and recreate this as an AutoCAD drawing.
