HI everyone I am looking for help on how to create a lisp that open the linetype manager and then selects the load option, and then the file option then, it should take me to my desired path. I have a screenshot below showing what I mean a little better highlighting the options I want to focus on. My goal is just to have the last window open up so the user may select the linetype folder they desire instead of going through the steps of finding the location of the linetypes in the server. this would save time on training on my end. If this is unclear please let me know so I can try to add more information. Thanks
