Is there any OnDemand course for footing design using Eurocode ,the point of interest is in sizing load combination ,by default i see this which is found in RCDC i would like to know what is Set A1, and is it correct to use set A1 which has only 1.0dead load,or i should use 1.0dead + 1.0live load?

if yes, please share me the link

I managed to solve the issues ,by using add load combination from regular structure, and not from analysis.
