Re: [OpenSCAD] Removing all surfaces in the X-Y Plane

You could then edit that polygon to remove all
the faces where all points are on the same Z height (IE they are flat on the
XY plane). Not sure if it will produce an error if you try to render the
STL as it will certainly be non-manifold, but if it works it's highly
reproducible...
