What does 'EC3' mean for the Structrual Standard selection? Why isn't AISD a choice for the Project Standards?

[#2]

That's a European standard....

Thank you for your reply. How do I select an Imperial standard? I know I can bring up Imperial for all the shapes (AISC) under the Profiles tab,a nd Imperial measures under the Units tab. Is that all I need to do? Does not seem correct that I accept European standards for a job requiring Imperial measures and profiles.

For some reason they default in European, but it will stay imperial once you change your settings.
