I do not know why difference() does not work for me.
Hi,
A newbie is here. I created this little program below, which works. Some
parameters are not shown, their value is some real numbers. However when I
uncomment the commented out 3 lines and put in the needed '}', then it does
not work. F5 does not give any message, but does not draw the
airdirector(). F6 report errors:
"The given mesh is not closed! Unable to convert to CGAL_Nef+Polyhedron.
"The given mesh is not closed! Unable to convert to CGAL_Nef+Polyhedron.
and then it also does not draw the airdiryctor()
I do not want it as a solid. I wanted to hollow it out. That is why I
create the difference of tho ellipses. Why it is a not supported operation?
Any good tip how I can achieve what I want? Any tip how I can copy and
paste from the error log? I am using a Mac wit Catalina and OpenSCAD is the
latest stabil version.

Maybe I'm missing it, but I don't see the closing brace for the difference.
