Dear Frank,

Thank you for the overlay scalebar macro. It works nicely.

Best Regards,
John Lim

Dear John,

I took a scalebar macro that Wayne at some point created and hacked around it a bit to create a scalebar overlay macro tool

I am sure that this kind of macro is not written very well, but for me it works. Give it a try

Best

Frank
