Reticular beams nodes

[kubbah]

Hello
I would like to ask for the best way to draw
1. nodo trave reticular
2. special node reticular beams

thank you 1000 for the help

 

[gfrank]

How should the knot be?
a plate that binds all beams?
or how?

 

[kubbah]

I have to do 2 different in different situations
see the annex

a. star knot with triggers (typical hinge for reticoarsals)
b. Single knot

 

[gfrank]

with regard to the knots of type you have to equip the pravi of a head, like that attached, and make the "plate" of circular connection through a family (circular extrusion)

 

[kubbah]

How do I connect the head to the beam then?

 

[gfrank]

I recommend doing it directly on the beam: see box at the bottom right of the attachment of the previous message.
the plate (circular) will have to be a family built with extrusion. the same must be divided into "spicchi" and each eye will have the slope (from the point of meeting - center - of the axes of each beam) equal to that of the beam to which it will be "embluded".
I attach the example family. the parameters are missing.

Otherwise, if you make a family of only "head" you enter the project with appropriate reference plans . e.g. a plan (plant) with slope equal to that of the beam.

for the type b node, you could make a family "limited to the zone" of connection of the beams. the beams intersect each other, and then with the subtraction solids "to remove the parts " that cum. in practice you create a family of the "clean" meeting point. every beam will have its own slope. once inserted in the project, you will have to reduce the length of the beams, until the connection with "mozzicons" built sil nodo.
