AutoCAD is essentially a vector drawing application. However, there are occasions when it would be useful to display raster images as part of your drawing. It would also be useful if you could make basic modifications to images and to be able to scale them.

Using such tools, you could use an image to trace some base information. For example, a raster map could be used to draw vector contour lines. You could also use raster images in place of vector symbols to add realism or personality to a drawing.

Fortunately, such tools do exist within AutoCAD and although they don’t approach the functionality of a dedicated raster image application such as Adobe Photoshop, they are adequate for most purposes. This tutorial shows you how to use all of the tools on the Image section of the Reference toolbar, shown below. The tutorial will show you how to attach an image to an AutoCAD drawing and imagelcip to manipulate the image appearance.

The tutorial also covers some of the extended image options included with Express Tools and how to control image objects with the Properties Window. If you would like to follow this tutorial closely, right-click the Imagdclip Image on the right and download it to your work folder.

When you have completed this tutorial, you may like to complete the Using Images exercise in order to get some practical experience. There is also a techniques tutorial, Scaling Images that demonstrates the best way omageclip scale raster base information. To display the Reference toolbar in AutoCAD, select View Toolbars… from the pull-down menu, scroll down the “Toolbars” list and put a check in the box against “Reference”. You can follow the tutorial from start to finish in order to learn all about images and AutoCAD.

However, if you just need information quickly, use the QuickFind toolbar, above to go straight to the command you want or select a topic from the contents list. The important thing to remember about images and the thing that causes most confusion amongst novice users is that they are not actually inserted into a drawing as the “Insert” pull-down menu might suggest.

Image files are attached to AutoCAD drawings. In other words, images do not become an integral part of a drawing. AutoCAD merely looks for images that have been attached and loads them as required. There are pros and cons to this method. Each time the drawing is opened, AutoCAD uses the path to find the image file and displays it.

This works fine providing both the drawing file and the image file remain in the same place. However, if like me, you travel around and work on different computers, this can cause problems.

My solution is very simple and consists of just two rules:. Attaching an image to an AutoCAD drawing is a relatively simple 3-step process. This involves selecting the image file, setting a few parameters and then picking points to position and scale the image. Before inserting an image, it is a good idea to create a new layer for your image. This way, you can easily control the display of the image by turning the layer off or on.

Use the Layers command to create a new layer called “Tree Image” and set it to be current. To begin, start the Attach Image command from either the Insert pull-down menu or the Reference toolbar.

The Select Image File dialogue box appears. Use the dialogue box to locate the image you want to insert or the Tree Image if you have downloaded it. When the file is selected, an image preview appears. To complete the selection, click on the “Open” button. The Image dialogue box displays and allows you to set various parameters that determine how the image will be attached. The Image dialogue box is shown below. As you can see from the illustration above, the Image dialogue box has two main functions.

Firstly it allows you to decide whether AutoCAD remembers the image path. Secondly it allows you to decide whether the position insert pointscale and rotation of the image are specified on-screen or within the dialogue box.

For most purposes, deselect the “Retain Path” checkbox. Other settings can be left to their default state. Your dialogue box should now look like the one shown above.

Click the “OK” button to proceed. Now look at the command prompt. AutoCAD will now ask you to specify the insertion point the lower left-hand corner of the image and the scale because these two parameters were set to “Specify on-screen” in the Image dialogue box.

Follow the command sequence below to complete the command. Pick a point in the drawing area to fix the lower-left hand corner of the image. You needn’t be too precise at this stage because you can always move the image later.

However, you could always enter a co-ordinate value if you know exactly where the image should be placed. To scale the image dynamically, simply move the mouse. You will see the image outline change size as the mouse moves. Pick a point when you are happy with the image size and the full image is displayed at the required size. If you want, you could enter a scale factor instead of scaling dynamically. The default scale factor is one. This means that the image will be inserted so that its width is one drawing unit.

So, if you want the image to be five drawing units wide, you could set the scale factor to five.

AutoCAD Command imageclip

As the name suggests, the image manager is a general purpose utility for managing your raster images. Using the Image Manager, you can attach new images, detach existing images, unload and reload images, modify the image path and display image details such as pixel size, colour depth etc.

The Image Manager is shown below. The “Attach…” button enables you imagdclip attach images to the current drawing. It works in exactly the same way as the Image Attach command described above. Sometimes autocav may want to remove an image from your drawing. You can, of course, simply erase an image but since you can have more than one instance of an image in your drawing, only that one instance would be erased and AutoCAD would still look for the image file when the drawing was opened.

The only way to remove all instances of aautocad particular image and to stop AutoCAD searching for the image is to detach it. To detach an image, highlight the image name in the list and click the “Detach” aitocad. Beware of using the Detach button. Once an image has been detached, all position, scaling autocav clipping information will be lost. If you just want to remove an image temporarily, it is far better to unload it.

Unloading an image, removes the image from the drawing but AutoCAD remembers any position scaling and clipping information.

When the image is reloadedit will reappear just as it was before you unloaded it.

To unload an image, highlight the image name and click on the “Unload” button. To auttocad an unloaded image, highlight the image name and click on the “Reload” button. When an image is unloaded, its boundary remains visible in the drawing. You can turn image frames off using the Image Frame command.

There are a number of reasons why you may want to unload an image. Firstly, images can take up quite a lot of computer memory and so your computer may work more quickly with images unloaded. Secondly, you may simply want imxgeclip hide images so that the drawing looks clearer while you are working.

Of course, you could also do this using layers if your images are on their own layer. The “Details…” button displays a autpcad box showing all relevant information about a particular image.

Notice that on the example below, the “Saved path” and the “Active path” details are different. This is because the “Retain Path” option was deselected when the image was attached.

The saved path is where AutoCAD looks for the image file when the drawing is opened. In this case, it only looks in the folder where the drawing is saved.

The active path is the actual location of the file on this computer. If I copied my working folder onto a Zip disk or to a different computer, the saved path would remain the same but the active path would change to reflect the actual location of the file.

The “Image found at” area of the Image Manager allows you to change the active and saved paths of any attached image. You can change the image path imageclipp by clicking on the “Browse…” button and navigating your way to the image location or you can change the image path in the edit box.

Changes made to the image path in this way will affect only the active path. If you want the changes to apply also to the saved path, you must click on the “Save Path” button. The Image Clip command enables you to clip or hide part of an image. There are two types of clipping, Rectangular and Polygonal.

A rectangular clip allows you to hide that part of an image outside of a defined rectangle. A polygonal clip allows you to hide that part of an image outside of a defined polygon. See the images below to see the effect of the two clipping types. Only one clip is allowed per image. However, you can apply different clips to different instances of an image. P for Polygonal Specify first point: You can use “U” to undo any picked point, just as you can with the Polyline command.
