Parts set to hidden in drawing

Good Morning,

I've had a search of the forums, and didn't come across any similar topics.

I'm seeing an issue where parts in my assembly drawing are set to hidden, where I don't want them hidden. I started to go through and set them to 'Show', but I've realised its in the order of 30 hidden components, maybe 5% of the total number of parts in the assembly.

I'm confused as to why I'm seeing this, so if anyone can enlighten me, I'd be interested.

  • My drawing consists of a Right view (cropped), and a sectional view
  • The parts are not hidden in the assembly itself (in any configuration)
  • I have only the default display state (Display State-1)
  • I haven't set any part to Hide in the drawing
  • Hidden parts are both top level parts, and parts within sub-assemblies
  • I have a subassembly used twice (reference to the same assembly file). Two parts within that subassembly are hidden in once instance and not the other

In most cases where I have multiple instances of the same part, if one is hidden, they all are.

I have been messing about with the visibility of the components in the assembly file previously, but the latest copy (both local and in the vault), have no hidden components at all.
