Problem in Import DWG

Hello,

i'm trying to import a dwg (generated with AutoCAD2012) in CorelX6.

The DWG have 2 hatchs: one red and one blue.

When i import the dwg i lost the hatch color and the "circle" area.

AUTOCAD DRAW:

COREL:

 

I have the same problem even if i saved a dxf.

I missed some option? someone else have the same problem?

 

Thanks
