Here's a quick video, (the roof and beam system already created)

Alf,

True once the roof is modeled, add the sloped ref. plane and the roof and beam system will follow.

But this still doesn't explain how to model the roof, does it?

(unless I'm missing something?)

[#3]

Oh, the roof can be a simple roof with Roof by Footprint and slopes, as normal. The beam system is the one that needs to be created from a 3d view, using Orient to plane. Then you pick lines of the walls, and Revit will find the projection of those lines on the sloped reference plane.

Apparently you are correct. The edit points tool is available for roofs- however, my roof is sloped and the edit points tools doesn't show up when I select it - which is why I didn't see it the first time.

I will try the edit points method just for educational purposes, but apparntly I will have to start with a new flat roof element. Thank you.

If it's a simple slope, a roof by footprint with a slope in one side only should be enough. I don't understand the need for editing points.

One use of Edit Points--To set the roof to precise elevations where the steel supports are located below the roof,

or for crickets around penetrations on sloping roofs, or for tapered insulation.

In the OP's case--a simple "defines slope" in sketch mode, or a Slope Arrow would probably suffice.

Just showing him the possibilities Revit offers for other situations as well.

If the edit points tool works for my application.... the only value or need for it would be to have more control over the interface between the structural elements and the roof element. I have found it difficult to edit the slope accurately enough to align the roof with the structural elements below.

Your suggestion to reverse the work flow solves that issue, but if for some reason I have to model the structure first, then the edit points tool might be best. I don't know, I haven't tried it yet.

You are both right. Thank you.

PS - ccollins makes a good point with respect to tapered insulation. My roof is a simple slope, but it will also have tapered insluation to roof drains.... which I haven't tackled yet due to trying to figure out the basic roof.

Again, thank you both for your excellent contributions.

In my opinion, the Editing points option is good in the cases that Cliff has mentioned. I would not recommended as a tool to start the creation of a roof with a simple constant, slope, because it can create issues with incorrect thickness. If that's the case, simply use roof by footprint.
