I am using version Premier X13. This is a duplex model with each of the units, plan left and plan right, copied and pasted into a new plan. The floating fascia boards and ridge cap are left in the place that this left hand unit was when I orginally pasted it into the new plan. Then I scooted that left side plan into position to attach it in the proper position with the right hand unit. I did try to restart the program and rebuilt the 3D both to no avail.
