It is a hatch, you could for example manually override it in the linked file. Or change the material.

Another option is to make an override in the host file for all floors in your linked file. There are infinite options to solve it. More or less.

can you say to me the steps please

Are you allowed to modify the linked file?

[Anonymous]

yes 
i want to make the hvac system at this view 
and going to v/g and can't find the fill pattern option to unchecked it

VV....Floors....Projection/Surface column click in the pattern box and uncheck the "visible" box for Pattern Overrides.  You don't have to open the linked model at all.

Yes, the surface pattern for floors can be turned off, but where you do it will depend on the Visibility Graphics settings for the Revit links in the view (template). 

Control over the visibility graphics for linked files can be done in many places depending on the VG settings for the link, which can have priority over other settings. Knowing these settings will tell you where to go to turn them off. It could be the object styles for the project, the view template for the view, the V/G overrides for the view, or the V/G overrides for the Revit Links in the view. There may be other ways, too.

The view settings for the link can be found here:
