Hi fsteyer,

I can think in several possibilities
1 - If the roofs appear in the floorplan but not in 3D--> Select one of the roofs and check the elevation (Edit--> set object elevation). Check if the elevation value is ok with the height of the top of the walls. Perhaps the roof is now near the moon :-) This happened several times in my drawings!
2 - If the roofs appear in the floorplan but not in 3D--> Go to your liveview window. On the toolbar you will find a pencil icon, click on it and you will see a menu of the elements appearing in the 3D view. Verify if the roofs are "crossed" with an X. If so, uncheck it, and your roof will appear.
3 - If the roofs appear in the floorplan but not in 3D--> Perhaps you clicked on the 3D Cut-away Slider. It is on the top left of your liveview window and there are five available cuts away (front to back; back to front, left to right; right to left and top to bottom). You just need to move the slicer back.
4 - After the use of the Roof Wizard, be sure to accept the changes before you close the Wizard
5 - If the RW doesn't generate the roof--> This issue happens when the exterior walls are not linked--> the plan must have a completely closed perimeter, drawn with exterior walls
