Complex flat roof by slope (not sub-elements)

Hello, 

 

I want to model a complex flat roof with multiple slopes (1.png). The roof consists of a flat slab and the slope is to be achieved in the insulation layer - because of that I need to model it using the sub-elements menu - or at least I don't know of any other way. I tried to do it like in this video: https://youtu.be/vsfhgwbIXX0?t=497, but it's not working for me because of the higher complexity of my roof.

 

The problem is, I know the slopes, but not the heights of the edges - and I need the latter when using the sub-elements method. Because of that, my model turns out terribly triangulated (2.png), when it's supposed to be much simpler. Each of the green points would have a different height that I cannot specify. 

My question is - is there a way to model a flat roof with a varying thickness insulation, by defining the slope and not the height of all the edges?

 

Thank you in advance for taking your time.

Find the point elevations the "old school" way...draw and dimension the Roof in Elevation Views using 2D linework/Ref. Planes.

Share the roof you have.

I've deleted the roof shortly after writing the post, because it was quite useless. But I'm attaching a file with a sketch of the roof and a small part modelled (only a slice of the roof that has the same slope value and direction - I could do the rest like that, but it would be tedious).

I was thinking about this, but it would take hours to do and I think all the triangle lines would still be there.

So, it's the triangulation you are trying to solve for?  Yeah, I can see why it triangulated so much from your screenshot.  Maybe adding Split Lines can smooth out a little. Have you tried that?

If you only want to hide the lines, then turn off Roofs > interior Lines.

Basically yes, I want to solve the triangulation. But I can't just turn off the lines because they break the actual geometry. If you look at the 2.png screenshot, I want my roof to be just the green and blue lines, without the black ones. But if I choose to simply not display them, the sections and 3D will still be wrong.

The blue lines are the Split Lines (and in the actual roof they are valleys? I think that's the word for it) - and I don't know  what other split lines I should add.

See attached for a couple of possible approaches.

Break the job up into 4 separate roofs and manually align ridges.

Thank you! The one on the right is exactly what I wanted to do, but it's also great that you included the second one, because I didn't know it was possible to do somethig like that.
