How do I Edit or Delete an Inserted AutoCAD Drawing?

I inserted an AutoCAD drawing with the wrong scale and can't delete it. How do I delete or edit the inserted drawing?

Answer:
If you are unable to edit a CAD drawing, it is likely because the option to Lock size and position was selected at the time it was inserted. If you are unable to delete a CAD drawing, it is likely because the option to Lock against deletion was selected at the time it was inserted.

You can edit CAD Drawing Properties can at any time by double-clicking the image or by right-clicking it and selecting Properties from the CAD Drawing Object sub-menu.

The CAD Drawing Properties dialog appears. Use it to change any properties, including disabling locks, then click OK to save the changes.
