I had to reinstall Preform 2.15.00 on my pc because I suddenly noticed that the base of the support looked like the old type flat base and with no option to label them in the menu??!! After reinstalling I still get the old style base and I absolutely need the latest version because I’m producing thousand of rings that I need to identify after printing! Very strange! Preform shows the old base style with no option to label the base when CASTABLE RESIN selected. It goes back to the latest base design when I switch to GREY or TOUGH resin. WHY???
