Hi, I have spent the last hour trying to solve this and am stumped, basically I want to subtract from a curved surface to create an hole in the base of this shelter. I figured the way to do this (not sure if there is a command) is to create a block place it inside the curve and then use the trim tool to remove the curved surface where the block intersects it…
however something weird happens to the shape when I delete it, please see the screen shots
as you can see from that above the curve shouldn’t have that line cut through it
this is what I am trying to achieve ^
here is the technical drawings of before and after I remove the surface to explain whats happening
pretty stange… I dont know what I am doing wrong so if anyone could shed some light I’d be grateful!
