I got a roasting today from my boss because Revit couldn't display some roof hatching properly.
If you have a look at the attached screen shot you can see that there is some hatching at the top which displays correctly, but then on the roof under it and on the lower roof I get a grey shade, almost as though the lines have blended together.
But the thing is, the roof hatching that does display properly is actually a more dense hatch than the one that's not.
I get the same results when printing to a physical printer, PDF and DWF.
Since I can't control the line thickness of the hatching, only it's colour I don't know what to do to get around this.
This is not the only project it is doing it on either. It happens in many others.
