Under Purlin No Material Option

Hi,

I am trying to build rafters for a roof but am getting stopped at Dialogue box, specifically, Rafter Tools > Materials, Selections & Finishes > Under Purlin Material. There’s just a blank selection box; so I can’t choose anything and I am not able to create my own either. I am guessing the North American Database may be missing this material? Can someone please advise?

Thanks
Rob
