Hello Kerry,
Stepping in here. Couple different ways you can do it.
- You can draw the boundary manually in LayOut (if it will likely be a one-time thing that won’t require many changes)
- You can apply a 2D Graphic to your “ELEMENT_Earth” Layer; meaning you would make a group with your geometry inside of ELEMENT_Earth with your 3D Geometry and assign it to “CONDOC_3D Object” and then draw your boundary lines, make a group and assign it to “CONDOC_2D Graphic”.
You may need to update your scenes to show the 3D Object and 2D Graphic after you make the changes in option #2, but that one will likely work.
Make sense ok? Thanks!
