I want to change the color of everything in my drawing except for 3 layers. There are hundreds of layers and blocks in this drawing, even after purging. I want to avoid just exploding everything and putting it on one layer.
I want to change everything to grey except for the 3 layers I'm working in. I'm using ACAD LT so I can't create a script to do the job. The only thing I can think of is going into the layer properties window and selecting each layer and changing the color one at a time. I'm wondering if there's a better way of doing this. Any help is appreciated!
