What config option makes surfaces hidden in drawing mode?

I have created pipe threads in a mold base using a revolved surface. Now my drawing has alot of magenta and yellow lines that I can't make hidden. I thought I read in this forum that there was a config option to make them hidden just like the cosmetic thread features.



Can some redirect me to the thread?



Thanks in advance!

Blank the surface layer...

I need to see them in hidden line.
