I need to change the plotstyle property to be set by layer. When I get architectural files from an architect they have their plotstyle set to something specific they use. I want to set all the layers to be in the bylayer plotstyle or any other specific plotstyle I want. I been changing the color and the lineweight manually when I change the layer properties but it would be nice to change it all at once with a lisp routine. I was trying to make a lisp routine that would select all layers then change that property using the lisp, but that is not working. I have a lisp routine that sets my layers to be a specific plotstyle, but that only sets layers it doesn't change the properties of existing layers. Any ideas would be really helpful and thanks in advance
(defun c:test ()
(command "-select" "all" "-plotstyle" "ByLayer" "")
)
