Export to autocad hatch not coming out correct - Revit MEP 2013 - autocad 2013

[gookeeper]

Hi

When i export out to autocad MEP im  having problem with the hatch not coming out properly(kinda patchy).

I've attached 2 images one how it used to export and one as it exports now.

i dont believe ive changed any settings for it to come out differently.

im using cable tray - filters with hatches to identify the types.

Any ideas why this has started to happen? this one has beaten me

Thanks

Guy

Hi,

Have you tried mapping the patterns to a standard AutoCAD  hatch pattern file?

Please see the picture attached.
