I am a Landscape Architect and I have never worked with layer filters in CAD before and was wondering if someone could please instruct me throught it.
 
My CAD files at work have numerous XREFs and outside CAD data within each file making it very difficult to make edits and do design drafting. I would like to create layer filters in order to organize the files.
 
For example, I would like to make a layer filter that contains only the layers in a proposed LAYOUT format that will show up in model space and eliminate all the other layers that are not in the filter.
 
Can anyone help me?
