Using the Layer States Manager in AutoCAD 

Total life changer, now i dont have to change every single layer in every single viewport in every single layout, thanks!

Thank you so much for that video. All clear and so useful to apply from now. Regards from New Zealand :)

Tremendous. Wish I knew this 5 years ago!

Great!

Thank you. Very useful tutorial!!

it was i am looking for, thank sir.

Thank you so much!

Wow.. i just knew it... thanks man... so i dont have to copy entire drawing to a file to make customization...

is there a problem with performance of the program when using various layer states applied to various different viewports?

I have an issue where I will apply layer states inside viewports of all my sheets in a dwg, but when I reopen that file the later states are not assigned, and I have to restore them all again. Is there a way for the viewports layer state to be saved, for the next time I open? It's tedious to restore them every time I want to plot
