How to use brushes in blueprints

more simple stuff.

there is nothing written into the UI so you can measure ANYTHING in ANY way.
yeh theres a grid thats nice. then when you look at it, what ? its invisible?
in some other dimension?

so i need to make a BRUSH. the right way.
then i can lay it down, set its specific size. etc.

but no - all i can add is a static mesh, which only allows you to modify through “scale” which is b.s… and should never be used
its not size its scale, the brushes have size. the mesh has to be made to a specific size.

so how in the hell do i get my character on the ******* floor --------- im staring at it i think its, at my nose level
maybe its over me maybe its under me i dont know

oh wow i was going to screenshot it but it didnt keep my view setting
here i go trying to “find” the floor again.
