AutoCAD's Reference Manager isn't just for referencing drawings, we can also use it to attach image files. In this lesson, we're going to learn how to attach and manage images. We'll also look at some common tools used to modify referenced image files. On my screen, I have a concept plan for a proposed fast food restaurant. As part of the site plan, I'd like to add a location map to identify where in town this project is being constructed. Now my location map is an image. It's a JPEG and I'd like to place it right here in my layout. To reference the image, I'll bring up the Reference Manager.
I can do that by visiting the Window menu and I'll come down and select Reference Manager. I can also use the keyboard shortcut Command+7. Now this is the same Reference Manager that we used to attach drawings. As you can see, I already have three drawings referenced into this file. I have an Existing Conditions drawing, one for the proposed conditions and one for the proposed shading. To reference the location map, I'll click the Attach button, and then I'll change the File Format to All image files.
And then I'll look inside our Exercise Files directory and I'm going to select the 05_map.jpg image, and I'll click Open. This brings up the Attach Image dialog box over here on the right. I can see a nice preview of my image. I can open up these flyouts to see information about this image file. On the left, I have the standard Insertion Point, Scale, Rotation, and Path Type settings that we see on the Windows platform. I'm going to leave all of these set to the defaults and I'll come down and click OK.
As you can see, I'm holding the image at my cursor. I'm going to click to place the lower left corner and then I'll drag this up and click to set the image size. Now just like in the Windows version, I can use grips to resize the image if necessary. I'm going to select this image from the edge, I'll select this grip, and I'll drag it down to here. When I'm finished I'll press Escape. Now, notice that the image quality appears to have broken-down; don't worry this is just a screen display issue.
If I zoom in closer, you can see that the image is just fine. Let's zoom back out and I'll center this on screen, and we'll take a look at the manager again. Notice that the references are organized by type. I have a group for drawings and I have one for Images. As far as the tools inside the Reference Manager, they work the same for images as they do for drawings. If I select the Image Reference, that image is highlighted in the drawing. I can use this icon to load or unload the image. This one will detach the image file.
I can use this one to reload the image file in the event it's changed, while I'm working on this current drawing. Down at the bottom of the manager, I can see information about this file. If I drag down far enough, I can see a preview image. If this image gets moved on the network or is renamed, I can click this Folder Icon to navigate to the new location of the file. To deselect the image on screen, I'm going to click in the middle of the manager, and then I'm going to press Command+7 to close it, and we'll talk about some of the other commands associated with referenced images.
Let's make this a little larger on screen and I'll center it. Now maybe I'd like to clip this image, or screen it back, or maybe I'd like to remove this frame around the outside edge. All of the commands associated with editing referenced images can be found in the Modify menu. I'm going to come down to Object, and I'll come over to Image. Let's look at the Adjust option. I'll select my image and press Return. Adjust is where I can find the controls to adjust the images Contrast, Brightness, or Fade.
As an example, I'll select Fade and let's screen this image back to 50%. I'll type 50, and press Return. I'm going to press Command+Z to undo and put the image back the way it was. Let's go back to the Modify menu. I'll come down to Object>Image, and this time we'll talk about Frame. This is how I can turn off the boundary around the outside of the image. Notice that the current setting is 1. 1 means on. To turn the frame off, I can set this to zero and press Return.
There is actually one more setting. I'm going to press the Spacebar to relaunch the command. If I set this to 2, the Image Frame will display in the drawing, but it will not show up on the plots. Finally, let's talk about how we can clip a referenced image. I'm going to come back to the Modify menu. I'll come down to Clip, and I'll select Image. I will then select the image I'd like to clip, and notice that we see the same clipping options that we have when we're clipping a referenced drawing. As an example, I'm going to select New boundary, and then I'll press Return, because I'd like to create a rectangular boundary.
I'll pick a point here and I'll come down and pick another point over here. To adjust the boundary, I can select the edge and I can move the grips. I'll select this grip and move it over here. I can also click this Arrow, if I'd like to Invert the clipping boundary. When I'm finished, I'll press Escape to deselect. To remove a clipping boundary, I'll go back to the Modify menu, I'll come down to Clip and select Image. I'll select my image and then I'll select Delete.
Knowing what we know now, I'm going to finish this location map by adding a Multileader. To do then, I'll open the Dimension menu, and I'll come down and select Multileader. This restaurant is located on Court Street, right here. So I'll click and I'll pull this out and click. I'll then type Project Location and I'll click Save. Typically a leader like this will have a dot at the end. Let's select the arrow and my Properties Inspector is showing all settings.
I'm going to drag this down to the Arrowhead setting and I'll change this to Dot. When I'm finished, I'll press Escape. Let's zoom out. My text is a little bit hard to read sitting on top of the image. Let's clip the image around this text. I'll move up to the Modify menu, and select Clip. I'll select Image. I'll then select the edge of my image, New boundary. I'll press Return to accept a rectangular boundary.
And I'll click right here, and I'll click again over here. Now, this is the exact opposite of what I want. Let's select the boundary and then I'll click the Arrow to invert the clip. When I'm finished, I'll press Escape. As you can see, when working with the Mac edition of AutoCAD, we have the same referenced image functionality as we have on the Windows version. The only learning curve involved is adapting to some new tool locations.
