Inserts a reference to an image file.
When you attach an image file, you link that referenced file to the current drawing. Any changes to the referenced file are displayed in the current drawing when it is opened or reloaded.
The Select Reference File dialog box (a standard file selection dialog box) is displayed. Once you select an image file, the Attach Image Dialog Box is displayed.
After the file is attached, you can adjust and clip the underlay through the Image Ribbon Contextual tab.
