Just in case - display order only applies to curves and hatches. It does not apply to surface objects.

Yes, i know, i used this feature with Rhino 5

OK, can you post an example for V6 where display order is not working as it should?

of course
I’ve omit to note that appear only on Render mode and Artique mode

in Shared preview is ok:

in Render preview

(the rectangle red and green is hatchs)
rh_order_display.3dm (23.1 KB)

Yeah, I’m not sure draw order is enabled for those display modes…

Ok, that’s not logical. Of the 10 preview modes, only two modes does not works.
Even the mode Cycle work !

Maybe a dev McNeel will see this article and make things better …
thanks.
