Answer:
When you upgrade an RFEM 5 add-on module such as RF-STEEL AISC, you will now have access to all national and international standards in RFEM 6 including AISC 360, CSA S16, EC3, and many more. The separate standards under each design material are no longer sold as separate modules. If you currently have multiple modules for the separate standards (for example, RF-STEEL AISC and RF-STEEL CSA), there will only be one upgrade fee for a material family. This will be a long-term cost savings.
