Colour Fill

[STHRevit]

Hi All,
I have a colour fill applied to my plan and I am seeing some rather strange effects.
Basically, on occasion, the colour fill does not pass through the door from room to room. So in effect we are left with white stripe accross the door opening.

It does not happen in all doors, only some of them.

Can anyone shed some light on this for me??

Check the door properties and make sure the door sills are not set above the floor level.

Yeah, that was the first thing I tried and all doors are set ot the relevant levels with no sill offsets.

Any other thoughts?
