How to create axonometric dashed arrows

Woah ​@RvdT , that’s exactly it! thank you so much! (see attached screenshot)
this did raise a couple of follow up questions, but no worries if it goes beyond the scope of this post.

- 1A) is there a way to have the line span multiple planes? (like faces of the cube) 1B) if so, is it possible to modify the angles of the planes it spans?
- when controlling the gradient how can it be made to follow the line? (beyond a more static stroke gradient, but also this can probably found pretty quickly online, so no worries again if it’s not worth the effort to answer)

i’ll restrict follow-ups to these so this post doesn’t drag on
but nonetheless thank you so much for the reply, it absolutely helped and answered exactly the question being asked!

hi ​@Bobby Henderson, thank you so much for your reply!
i have done an attempt but wasn’t able to make anything close.
is it possible to make it work? always curious to know more ways to achieve outcome
