display armored irons

[Mauro66]

Good morning to all, I would like to ask why the longitudinal armored needles are not displayed in view 3d, while they are correctly positioned in section. I attach two images to clarify my problem better.
thanks and good work to all.

I'm afraid I didn't see pictures of architecture or structure? How did you draw the needles?

I drew them with structure automatisms, after calculating them with another software.
