How do I send an image to the back in AutoCAD?

To send an image to the back in AutoCAD, follow these steps:

1. (Ensure no image files are selected.) This is crucial so AutoCAD knows you want to select an image to send to the back, rather than operate on a pre-selected one.

2. (Access the "Send to Back" tool.) Although the reference path is for a Bentley product, the general function exists in AutoCAD. Typically, you'll find a command like this: _DRAWORDER. You might access it from a ribbon panel, or type it directly into the command line. Another option, if available, might be found under a menu item relating to draw order (e.g., "Modify > Draw Order > Send to Back").

3. (Set the action to "To Back". In AutoCAD, after initiating the _DRAWORDER command, the command line will prompt you. You'll likely need to choose the "Back" option. The precise wording might differ slightly depending on your AutoCAD version.

4. (Select the image.) Click on the image you want to move to the back of the drawing order.

5. (Confirm the operation.) AutoCAD should then move the selected image behind all other objects in the current drawing space. You might need to regenerate the display using the REGEN command to visually confirm the change.

In Summary: Using the _DRAWORDER command (or its equivalent from the ribbon/menu) in AutoCAD allows you to specify that a selected image should be placed behind all other objects, essentially "sending it to the back". This ensures that other objects are visually layered on top of the image.
