Hi, I am working with Cameo Enterprise Architecture 19.0 version and am trying to specify the unit for a value property. In my work instructions it state I need to select the value property and then select the ISO button, I also found the following site showing that exact ISO button, but I am finding that my ISO button is missing. Any Idea's on why that is?
