I am trying to customize some transportation symbols but to no avail. "Help" doesn't seem to cover my needs. I just want to revise the text on a sign symbol or create a custom sign. Went to Style Manager, then Symbol Property Editor, but can't figure out how to customize the text layer.
Font Creator is a simple font editing software that I've found is very useful in the ESRI environment. I've made many custom symbols this way. You can add symbols to existing fonts as well, should you wish.
