Plane with Dashed line as border in 3D

[Anonymous]

Hi,

We need to show a slab, mesh, fill or zone borders with dashed line in 3D if we are looking from the top.

I created an object which 3D script is

pen 10
material “yellow colour”
set line_type “Dashed”

prism_ 5, 0.001,
0, 0, 0,
0, 1, 0,
2, 1, 0,
2, 0, 0,
0, 0, -1

lin_ 0,0,0, 0,1,0
lin_ 0,1,0, 2,1,0
lin_ 2,1,0, 2,0,0
lin_ 2,0,0, 0,0,0

In 3D I am not getting dashed line I am only getting solid line.

Is any one had any idea how to get the dashed plane in 3d?

Is there any object available as “3Ddashedline”?

yes thank you very much
I'll do some more research and ask about the GDL.
It seems that there are many difficulties in trying to understand gdl while studying alone.

Your advice is guiding my future.
