Detaching trusses from roof plane

[trialbyfire]

RS2010 - This has to be simple, but I cannot figure out how to fix it. Every truss in my project is somehow linked to one of my roof surfaces (but not to any of the others), and I cannot move the roof without all the trusses moving also.

See the attached images showing the roof moved up away from the building and the trusses moved also. I can move the roof wherever I want, and the trusses move up and down with it (vertically only, no lateral movement regardless of where I move the roof). The trusses on the left always stay in the same plane as the roof, and the trusses on the right always stay at the same height as the ones on the left.

The roof is a floor system family, not a roof family. The trusses are a custom family from the architect. I suspect some kind of reference plane or framing attachment issue? Or maybe something wrong in the truss family? Reference planes are turned on in the attached images, and showing hidden elements reveals nothing.

In the third image (Truss 3.jpg), I changed the slope of the roof from 3.5:12 to 6:12. You can see that the trusses on the right now are higher vertically than the trusses on the left when I do this.

I hope this info clues somebody into what's going on, because I'm admittedly clueLESS!

Thanks

well thats definitely a custom truss(probably an extrusion) it doesnt look like the truss tool in revit. best bet is to check its constraints to the roof(floor) and/or open up the family itself and dig around.
oh and that section head is uuuuuuuuhgly!

you can remove constraints by cutting items to clipboard and pasting aligned>same place if you cant physically find them.

Haha....well, the section head doesn't look like that exactly when it plots - what you see there is Revit's awesome lack of refinement with display graphics. You may not consider the plotted one gorgeous either, but it looks a lot better than that :)

Yes it's a custom extruded family, not a system Truss. I wound up deleting the roof plane and creating another one to get them detached since I couldn't find any controllable constraints. I saw some tips elsewhere about cutting and re-pasting elements to undo 'quirks' in Revit. I'll add it to the tool bag.

Thanks for the help!
