The case of three beams.

[Robert Horvath]

If we want to use the SAF workflow, we need to model the carpentry structure with a beam tool.
A frequent connection will generate a completely meaningless collapse.
As long as only two beams meet it is fine.

It would be best if RoofMaker could build the carpentry from column/beam elements.

There is junction order in the beam settings, but it doesn't help in this particular example.

If you are using Complex Profiles to define your different sizes, you could just rotate the beam 180 degrees so that it's reference line does not intersect with that of the rafters. No need for multiple layers. You do still run into the issue mentioned previously of you need the bottoms to trim which requires a SEO to fix.

re: "the better way would be a beam management inside the element"

In addition to layer intersection priorities in layer combos, each building material has a value for intersection priority.  Maybe creating extra building materials would be more useful to you than creating extra layers.

I'm talking about these things:

These kind of beam-structures (beams, not walls!) needs a lot of adjustment and intersection priority management. This construction isn't created out of the blue. It takes weeks of planning, discussion with engineers and fiddeling with Archicad to get it right.

Any enhancement with beam management is welcome!

In fact, the beam and column elements should be replaced by a truly functional linear structural element. The fact that Grasshopper is trying to figure out what is column and what is beam is more of a fumbling around a fundamental problem.

I agree completely with this last statement Robert, I had, in fact, suggested this idea to the GS team in regards to the live-connection years ago! 

In modern architecture there are structural elements that need a different approach from typical beam and columns, and this “new tool” could be in fact just a hybrid structural-profile-modeller that could, in due time, just substitute the other tools. Basing the identity of the elements in pure classification… 

[jorgebeneitez]

In fact, we could maintain all the geometry-methods so people won’t feel the difference with the classical tools 

[Barry Kelly]

I have been trying to find solutions to this.

Building materials don't help, junction order doesn't help.

The best I have so far is to split the horizontal beam int to 2 half width beams.

Or leave a tiny gap between the ends of the 2 raking beams.

I just found that if you offset the Reference Axis off by 1mm and drag the beam back to the center intersection, the ridge connects properly'.

[Barry Kelly]

Thanks Kristian.

Also works if you anchor the ref line to the side of the beam and re-centre the beam.

I had tried with anchoring top and bottom but didn't try the sides.
