I am drawing an as-built plan and utilizing a scanned image of the plan as a go by. The image is referenced into the drawing. Sometime I want to turn the image off by selecting it and clicking "show image" icon on the show image > options tab. After turning the image off, if I forget to unselect the image before continuing, I risk deleting the image and creating an unreferenced image.
I thought i could solve the problem by locking the layer the image in on, but then I can not turn the image on and off!
Try another method. Put all of the xref images in the drawing on their own layer. Then turn that layer on and off using the layer drop down (or Layer Properties Manager palette) depending on what you want to do.
