I am not familiar with using code in Visio but, your question drew my interest. I googled "using code to toggle layers in visio" and came up with multiple hits that may help you. Try it out...



HTHs

I did - and every one had nuances that would not work for me. I'm looking for a simple solution, nothing complex like found online. Furhter, I'm not familiar with coding for Visio. I'm mostly an Excel user. Appreciate your advice, but could someone familiar with Visio coding lend a hand.....
