I'm Having a similar problem. While drawing up a replacement part for the flush button on a toilet which requires a threaded part I get the same transparent surface if the helix is extruded to some lengths. Other lengths seem to be fine. To try and work around this I have drawn the helix to a longer length than required and then extrude cut the extra off. Unfortunately the extrude cut fails as it will not cut through the helix. I have also tried to extrude cut a keyway on the side of the helix and this fails too. The only successful cut of the helix was a revolve cut on the bottom to give a taper to the end of the thread.
If anyone has some insight or similar issues and workarounds to fix this I might be able to grow back some of my hair I have extracted from my scalp.
