Changing Materials On "All Roofs'

[HumbleChief]

I have job with a pretty complex roof design with 16 - 18 roof planes and want to change the fascia color on all roofs at once instead of selecting one at a time. If I select all the roof planes either with the 'Edit All Roof Planes' tool or group select them with the shift key the material dialog box is grayed out. I can select one or two and the material option is there but when I add another the dbx is grayed out again. Changing defaults does not affect the existing roof materials. Stumped.

 

Attached is the dbx with the grayed out materials option. Am suspicious about the plan file as it seems it should be much bigger....but it's posted below.

No problems here selecting various ways.

 

THANKS Eric, Can I assume those 'various ways' are edit all roof planes or group select? Wonder what I'm doing differently?

OK Chief, you win. Just re-opened the plan file and it works as expected using edit all roof planes. Thanks again Eric for taking your time to help.
