I am very new to dynamic blocks and everything they can do. I have seen many blocks with multiple visibility parameters, This option would be amazing since I'm trying to make a weld symbol. I have loaded (visibility-add-eng.lsp.) but now I don't know what to type to pull it up so I can do more. Such as (visibility_add) and (visibility-up) both have to do with adding more visibility parameters. Any and all advice will be greatly appreciated. Auto CAD version - 2017Thank you!
