The "drop down classes menu" is aka the Organisation Palette? I don't think the Cyan in the cavity slider is a class attribute. Cyan isn't used as a solid fill for any of my classes and I even tried turning all my class fills to "None" and that didn't change the cyan. I noticed in another VW file a cavity slider wall fill was white rather than cyan. Just can't find where to control it. Thanks for your help David. Have added my signiture :-) Cheers

Yes I have tried playing with the OIP colour and class settings but still no joy. I was thinking I might just have to add 2d rectangles as you suggested. Thanks for the response. The other bug I'm finding is that the copy/apply function for WinDoor doesn't seem to be working in 2016. Has anyone else found that?

Hi there. I am having another issue with Windoor since I started using VW2016. With cavity sliders the wall fill where the wall pocket is turns bright cyan colour rather than the colour of the adjacent wall. I can't find where to control this. Very annoying. Any suggestions would be much appreciated
