i append a curve from an old file for a wire with an helicoidale form or helix
but in this new file in most viewports it is invisible except the top view where i see only a very thin line
i do have a profile on it but it ios still invisible even if i change the seize of the profile
so what wrong with this curve se pic ?
and what is the name on the left CU ?
in the second pic you see one curve selected but the othere one is invisible see top pic
2 curve circle but theses are helix
