Angled beam intersection (bisector)

[Anonymous]

Hi there,
I always have the same issue with the beams on the roof. If I have the same cross section of the beam let's say 30x50 cm concrete beams and one in the end it's angled, the intersection must be on the bisect of the angle.
It's almost impossible to have it like this. The only solution it's to have a lot of SEO but it's waste of time.

Please let me know if you know any solutions for this.

Thank you!

Catalin,

I make my guard rails out of beams and columns, so I have this problem all the time on stairs.

When you angle a beam, it uses the perpendicular cross section as the official height of the beam. That is why it does not line up properly because cross section makes the beam thicker when it is plumb cut.

The way I fix it is to make the beam thinner.

Hope this helps.

It still won't be right, Jeff.

Roof objects will join correctly, if you don't mind using a roof in place of a beam.

ROOF SET TO ZERO THICKNESS AND AT THE APPROPRIATE BISECTION ANGLE AS OPERATOR IN SEO'S

Indeed, this is one solution. But in real life you can't make a beam thinner just because Archicad doesn't intersect well the beams.

I think this is the only solution, but as you know in design phase you need to change the angle or else ten times per hour and to make one SEO let's say per day but it's time consuming.

You could create the entire assembly using a complex profile and laying it down using a wall ACROSS the span direction.

There is another relatively simple and fast method.
See the attached image.
SEO is performed
The inclined Beam is the Target, the horizontal Beam is the operator.
Depending on the situation you perform a Subscription with upward/downward extrusion SEO.

ah....of coarse. Great solution......now why didn't I think of that! I always start my day at this forum,more hours saved!
Thanks
