The more complicated issue occurs when the hatch object and the linework are in an xref and the hatch “moves” to the front of the linework in the xref, even though the DRAWORDER has been set properly in the original drawing. You can also type “HATCHTOBACK” to send all hatches behind all other objects. If you prefer typing commands, you can type “DRAWORDER” in the command line and follow the prompts. Note that there is a command at the bottom of the pull-down menu that will “Send Hatches to Back.” This forces all hatches in the drawing to be displayed behind all other objects.
