I'm looking at design a leaf inspired roof design for a sustainable project I'm working on at Uni.
I tried using objective but I didn't get it to work as well as I had hoped (and as good as past experience...)

What materials will the roof be made with? Concrete?

Let me know if you need any help framing the roof. Or building it. I could use a trip to the tropics.

I would appreciate enlightenment on the method you used to execute this very much.
Thank You

That would work great Steve. I've not looked into it in great detail yet but I think an ISO 'explode' view of the roof structure would be excellent to show how it's constructed and the materials 'green' credentials (its a sustainability project)
I would appreciate enlightenment on the method you used to execute this very much.
Thank You
I made the curved arches by drawing it with a wall in plan view, exploded it, used the magic wand to make the fill of it a slab,
The curved valley beam is tricky. It will not be a uniform curve.
To make this beam, make a section exactly at the valley intersect.
Copy and paste the section view into the floor plan view so you can work on it. This will show you the exact curve you need for the valley beam.
Use the same process as before. Draw the beam with lines/archs use the magic wand to make it into a slab. View from the top in 3d and save as .gsm. When you go back to the floor plan, this new beam/object will by default be the one in the info box and you can place it like any other object. You may need to rotate it, flip it end for end, elevate, etc... to make it fit. Use section and 3d views to get it in place.
This particular valley beam is interesting. I used 3 different curves to make a very smooth fit.
In your case, you will probably not want the bottom plate of the leaf to be flat. You will want tilted leaves. To to this I would model them flat, then save the entire roof assembly as one model part and add to it a little .gdl script for tilt. roty rotx. Then do the SEO when you have the leaf parts tilted as you want it.
Just a tip. I would begin with laying out the rooms based on modules of
" ken x 1/2 ken ". Then make the roof in harmony with these units of measure. The leaves will be some ratio of ken x 1/2 ken also in length, width, and height. Find some geometric harmony for the whole thing and it will be much easier.
Take a look a the tile roof I modeled here
The trick is to multiply with virtical displacement horizontal instead of virtical as was shown in the illustration using Objective.
Of course, there are many ways to do this and lots of tools to do it with.

The framing is all done with a single object (Regular Profile). Rather than messing around with slabs, settings views, and saving GSMs, just draw the beams straight into a cross-section through the building. Use
The rafters can be done the same way - just cut a section, draw or rotate the rafter directly in the section (with
OBJECTiVE's ability to bend and/or twist the timber will give you more freedom to create organic forms. You might also want to refer to the use Peacebuilding is making of OBJECTiVE developing reciprocal frame structures for countries like Haiti.
