Help with Roof Please

[nbuitr2]

So I'm a complete newbie at Revit Structure and I need help with one of the designs that we're supposed to do,

So I did the whole floor plan putting in the walls, the grid, the correct dimensions, and the columns but now I don't know how to do the extruded warehouse roof. Its telling me to use open web joist purlins/gurders and that it has to be a metal roof deck but when I tried to do that it just ended up a big mess of slanted v's all over the place. Any help would be immensely appreciated I honestly don't know how to do this,

Thanks In Advance,

Nik

ps. This is the revit design I have so far

Can you describe how you created the roof structure and elaborate on what you mean by "a big mess of slanted v's all over the place"

Are you using beam systems or placing individual joists?

There are a few different ways of doing this type of roof. I will be happy to write up a step by step procedure for this later on but I don't have time right now.

I would model the sloped roof diaphragm next. Not sure how exact the open web joists need to be, but RedBuilt offers open web joist 3D families free for download and use. My one issue with the family is that you cannot adjust the spacing of the diagonal web members, so depending on the length of the joist, they could end up being pretty vertical. But, the depth is adjustable and they even have options for a tapered top chord. With those in the model, you should be able to attach the top of your columns to the top chords to make them look like top chord bearing joists. Hope this helps.
