Well, as usual, I was running late on a design for an entry canopy structure remodel for one of my ongoing projects. I was using a bunch of floating "beam-walls" on a grid and wanted to fill some of the openings with pyramid shaped skylights. Lazy as I am clever....here is my latest tip (or trick!):
Use the basic, 12" generic default roof. Lay it out by footprint with the roof slope toggled on for all 4 sides, set your slope etc; however, once it is the way you want it, edit it as follows:
Select properties, click "edit" and duplicate it renaming it to "skylight-pyramid" and edit the structure core to 1" thick glass rather than the default 12" and then change the accurender material from "blank" to a glass that you like. Voila!
This took me all of 1 minute...maybe! How cool is Revit?!
Hope this helps
