I am using 2013 version. (don't find a "lock" under toolbar.
I am a student with only AutocadLT experience. I can not find how to offset a grid line. Please, can someone help?
Hello - I am not sure what you mean by "(don't find a "lock" under toolbar."
As for offsetting a grid line - you have to start the grid line command and use the offset in the options bar (below the ribbon). You cannot use the offset tool on the modify tab.
