How to make the Engineer report show stats for other bodies

[BechMeister]

I've seen a few Youtubers saying that with the Fore Science! Update you can set the Engineers Report and Trip planner to show stats for other bodies than Kerbin? But I cant seem to figure out how?

I am making a vehicle that will fly from the mun to Mun orbit... and I would like to calculate its TWR on the Mun.. as well its Δv in vacuum. 

Did I missunderstand what the youtuber ment?

The engineers report won't help you. There should be dV info in the vab if you click the gear icon next to the stage info. Here you can select celestial body and situation (atmosphere, altitude, vac)

Thank you! It was just what I needed. Then I just need to know why something dont show any Δv
