Revit exports dwg one plan white others are correct

[Anonymous]

Hello, 

I have problem with Revit 2017 export to Autocad 2013 dwg file. In my project I have 7 floor plans, all have same color scheme but when I am exporting these to dwg files and open in autocad 2017 one plan does not contain any color scheme colours, while others are all correct. 
I have checked to make sure that floor plans have identical properties and made like 10 times this specific floor plan sheet all over again (in one sheet I have one floor plan) but nothing does not help. 

Maybe someone from you can help me?

BY LAYER elements???

Sorry, I didn't understood.

I'm seeing this as a mapping issue.  You're having difficulties mapping ACAD elements that are not set to BYLAYER.  That's how you control AutoCAD elements linetype and color in Revit. By Layer.

I just noticed that while I have 9 different colours in use, in 6 plans .dwg files there are 9 A-AREA-PATT layers, but the one where all colours are missing there are only two A-LAYER-PATT, but neither are showing in plan. 

All colours in use are colourful, his means i don not use white or black colour.

Make sure the floor surface pattern is not solid white, view is not wireframe. Better make a view template from a good view and assign it to others.

I made the template from so called good view and linked to the bad one, but it did not help.
