Big modeling doubt: How to handle sloped Roof-Wall connection with profiled Beams?

[Studio Precht]

Hi,

We have this big modeling issue. And collegue is advanced user, he is struggling to make it, but me as well who is pro, so if anybody has an idea, how to model it, that is not using morph, would be appreciated.

Is about roof-wall connection that has this specific ending, and to to so, we used profiled beam. But as well on the side we want to use profiled beam. But that one needs to be rotated in the plan, because the roof shape is sliced, and slanted in the 3d, because the roof is sloped. 

On the flat part works like a charm, but on the slanted one is a dissaster. I get that the profile cant be the same, but still cant figure out the rotation of the composite for the slanted edge. Bellow I attached the  screenshots. Tnx!

Hello @Studio Precht,

Have you tried moving the reference line of your custom profiles ?

Are you able to share here a .mod file about this part of your project ?

It is all about transitions,

You can only change one rotation angle at a time.

See this post ...

In there I have a link to another post that I found using the railing tool can help automatically with these transitions.

Railing can be associated to the roof so they will adjust as the roof changes too.

Here is one possible solution on this problems:

Wunderbar!

The last Video was not "the real deal", not exact enbough.  This time, we do it for the exact solution:

Thank you for your great videos. These are always inspiring!
At first I thought these angles were only possible without a transition element.
Watching your video, I came up with the idea of creating a gdl object that can calculate the angle without the morph.

Very short video about the workflow:

@Hmooslechner Many many thanks for the time you put into this issue. Much appreciated!)

wonder, if it would be possible, to do this with a label? Your calculation should be transferable to a GDL-Label.

Yes! It is even easier with a label. The label will upate when you change the slope of the roof.
