thats just a basic example for what i would like to see. if added these would probably be sized based on height. width. length and angle(and possibly thickness like a thin wedge). with it you would be able to create 4 and two long slopes adding massive amounts of detail to ships. when this update i was kind of surpised how usefull these slabs were especilly in the making of turrets and ship interiors.
the addition of these wedge and other slabs i heard was coming but just wanted to put this here to help.
while this would not be a neccisary update i'de say it would certainly improve construction possibilities
Edit: and yes i also know that i have already put a suggestion for this down and others probably have too. but i felt the need to elaborate with ahelpfull image
