My office recently came up with a new class standard. The names of the classes are the same as previously (AIA naming) but the line weights, colors and hatches are different.
How can I convert existing files with existing classes to these new class standards, without doing it manually? When I open "Create New Class from Standard," if that class is already in my drawing, it won't allow me to add it.
(i.e. a-wall-neww-conc is already in the drawing, I just want to change its lineweight, color, and hatch. But we have hundreds of classes, so doing it manually is super time consuming. And these attributes are already in the new standard.)
