Hello all,
I'm looking for advice on the best way to model a roof similar to the Portsoken Pavillion in London. I will attach image.
I have a placeholder roof modelled at the moment which was created my modeling a mass and picking the relevant faces for a roof. The issue is because of the complex shape, the roof is curved, which I do not want. My goal is to have it segmented in similar to the image attached.
Any advice or suggestions are appreciated, I should mention it is for a college project.
Thanks

This is a hyperbolic paraboloid. In Revit, you can model it like this:
1) In a generic model adaptive template, draw two splines of 2 points, separated as per the desired footprint of the roof, as shown in image # 1.
2) Select the two splines, and do Create Form. Suppose that points A and C will be the high points, and that points B and D will be the supports. See image # 2.
3) Select both points A and C and lift them to the desired height using the Offset property of those points. See image # 3.
4) Now you have a hyperbolic paraboloid. Now you can load this family into a project and create a roof or wall by face. If necessary, select the surface and do Divide Surface, showing only one direction, U or V, and use those lines to model framing members. See image # 4.
I have tried this and it has worked well, however I can't 'pick lines' of the subdivision to model framing elements. Should it be possible to do that?
In that case,
1) create a new generic model, pattern-based family. Do: Model line > Draw on face > 3d Snapping > draw 4 model lines. Verify that the model lines stay put if you change the size of the pattern. Then load this pattern family into the family of the hypar. Then apply the panel to the divided surface. Load hypar family into the project.
2) Now you have something that Revit can 'see', so that you can use Structure > Beam > 3d Snapping > pick lines.

Hi. This is similar to the last question, but not as complex. How do you model tapered soffits like this wood one shown in this image below.
The butterfly roof is the easy part. I'm asking how do you model the tapered wood soffits.
Are you certain that it is tapered? The left edge doesn't look like there is a taper but it might be at the low point...or it could be deceptive because of the image perspective. Unless you've been there and took the picture? ![]()
A second roof under the main with shape editing could accomplish the taper.

With the roof tool.
