Hi

I'm looking to see if there is a way to turn off `only` the hidden tangent line when exporting to autocad dwg or dxf - i want to keep the external (exposed ) tangent lines only as they give a better representation of the part, but with hidden tangent lines seen creates a overly cluttered drawing - i do however want to maintain true hidden edge lines but only have this option if i turn off all tangent lines which is not what i'm after

second is the `far side` (which is also hidden) tangent lines come through when i export and i also do not want these as i end up with lines on lines and in different layers (i use layer mapping) but the above should solve the second issue - but again makes for cluttered drawing so wish to resolve

as can be seen in the attached - green dash hidden lines over lap the external tangent lines `red circle`
