Rebar Tag Checker

Upon complex rebar jobs, which involve many bar marks and therefore many tags. It can be difficult to see if any rebar has not been tagged in a view.
By applying the rebar tag check script, it colours any rebar which have not yet been tagged in the selected view to 'red'. Once identifying un-tagged rebar, then tagging them, the script can be run again, where the previously 'red' un-tagged rebar, now return back to normal and all is fine with the World.
