When I create one layout in microstation, I can see the hatch from 3D section on generated draw. I Create the hatch from material and layer use.

It would be very interesting if can export layout in dwg, mantained the 2D hatch on this file! Because now, when I convert layout in 2D cad in dwg file, the section hatch convert and I see it in dwg file exploded in more lines or circle (dipend about hatch). This is more more heavy for the file and if somone must modify it direct on autocad it is not immediatly, because the hatch it's exploded.
