How to make a vector representing Up direction?[Solved]

@SamTheFox i think it will work for what i want to make, i have used this make lofting missiles before and it works on the current pci coordinates.

PLEASE NOTE that the up vector expression i showed you is only relative to the universe, not the planet

@SamTheFox nice that is even better.
Add on to the Y

(craft [Position] + vec(0, 100, 0))
i'm used to lua in roblox studio and i haven't used vizzy in awhile

i hope vizzy understands what a CFrame is...

@TomKerbal that doesn't have up direction.

I found the answer is to make a normalized inverted gravity acceleration.
Since gravity is always downard form current pos just invert it to get the up vector.

@TritonAerospace could be the Nav[Position] Craft Information in Vizzy program environment.
