Hi everyone, my aim is to create a macro code where the user can select one of the radio buttons and from there the code will be executed accordingly. The two options are semi-circular and non-circular workpiece, seen in the first screenshot below. The code seems to work fine for non-circular workpiece but when I run the semi-circular workpiece option, there is an error shown, as seen in the second screeshot. Do help me out on this. The semi-circular workpiece is radio button number 1. You can scroll down the code to see the statement "ElseIf OptionButton1.Value = True Then....."   I have attached the macro code as well as the semi-circular parts. Appreciate with all the help I can get
