AC 28 Skylight Roof cut fill default can't be changed

[Brad Elliott]

I have a project that has been brought up from AC 26. I have added a skylight to the roof and am getting a brick pattern in the roof cut. I have tried various materials as well a basic and composite structures but still have the same pattern.

If I turn the lining off it shows up clearly in he 3d model which I have attached. I tried turning the lining on as a work around and it covers in the 3d view but the brick pattern still shows up in sections and elevations.

How do I change or hide this pattern?

What is the exact name of the Library Part you are using?

[Brad Elliott]

It's Skylight Flat Panel 27

Looks to me like that brickwork is your roof?

You have  a zero height curb in the object so the curb material will have no effect.

Looks like you have also turned off the lining.

So you are seeing the edge of your roof and need to change the edge material of the roof.

Barry,

Yes, I had the lining turned off in the 3d image to show that it was overriding the steel material. I have attached two more images.

The one shows the lining turned on and covering the brick veneer. The second shows the brick veneer showing through the lining with the Elevation tool.

I'm starting to wonder if anyone else has ever used this library part? When I open a fresh AC28 template with the weird 28/27 library it is clear that the part is overriding surface of the cut roof. I'm just not able to figure out what it is. Using the attribute manager the surfaces and materials have the same id's in the two projects.
