How to set lineweight and color of Elment

Thanks. Alfonso.
I’ve revised gh definition.
It looks like 2D representation problem has been fixed.

However, crash problem continues. When I tried to copy, move, and rotate a placed custom VA beam,
Rhino crashes down, especially right after trying to copy.
I attached revised gh definition.
