Create sloped butterfly roof

Anonymous
Not applicable
Hi,

I'm trying to create a butterfly roof that is sloped. So essentially you have the butterfly form (it slopes down by 3 degree to the valley) and then the whole roof slopes by 7 degress from one end of the building to the other. How do I go about doing this? (I'm an Archicad beginner)

Thanks

You simply drag the end node of the pivot line (single plane roof).

Or you can rotate the entire roof and re-adjust the boundary points.

 

But either of these methods, you will have to figure out where you need the pivot line located.

 

Use the 3 point placement method Laszlo mentioned.

Determine the height of your roof at 3 known points - use walls you already have in place or add extra columns or walls just to get the heights you need.

Then place the roof in 3D, single plane roof with complex (polygon not rectangular) construction method.

 

The first 3 points you place will determine the pitch of the roof and then you define the perimeter shape.

You can pick any points for the perimeter and you can adjust it afterwards as well.

Thank you! The 3-point placement with varying column heights worked like a charm.
