it’s a bit more complex than I thought, it seems to have to do with objects staying in the Rhino model. As soon as I internalize and delete, the problem is gone.

I see similar situation but more complex than that.
- problem occurs only with monocrhome or artistic display
- if rhino document have just breps, arrows (that shouldn’t be visible) disappear if you select ALL breps (WTF)
- if rhino document have brep/breps and a/some curve, arrows do not show (correctly), but if you select all the curves, the arrows do show again (WTF2)
EDIT, addition:
- if all curves are selected but then you also select all breps, arrows disappear again.

That’s a remark I would expect from a newbie.

I think my definition doesn’t make a big difference here.
This whole arrow display is just a complete clusterfuck.
It certainly does for anyone who tries to replicate it 
Don’t be lazy when starting a thread.

@maje90 did you ever find a solution? I have some blocks from catia and when i work with them in GH they all display these bunches of arrows.

No Solution but a fix is to just explode the blocks until there are no more blocks. Then the arrows disappear. Thought I would leave this for the next person looking.
Hi @David_Richter,
This was fixed on 8.10 release.
Did you update?
I am on the following Rhino Version:
Version 8 SR12
(8.12.24282.7001, 2024-10-08)
Could you please share a .gh, .3dm file that reproduces the error?
Thanks.
