Hi! I want to model a beam structure (truss system) that connects to a column (also a truss system). Is it possible to get any tips on how I can model a connection between the two? Not sure what I should present of material, but here’s a snippet of the area around the connection:
I would like the beam to be connected to the column at the blue areas.
Best regards Per
Hi @perbhagen 
We can help you with specific issue related to the grasshopper API if your problem is related to our plugin.
Unfortunately, we can not help with grasshopper workflow specific to geometry manipulation. However, I would suggest to think how you would do it manually first and translate the logic in the parametric environment.
Definitely, @MarcoPelle ! Thanks! 
However, I was generally in need of a way to make a connection between the two elements (beam and column). Although I think I can use the PointConnection element. Do you think that would work? If so, what is the definition of the master point and the slave point?
it is a bit hard to give a tip/answer as we do not have the full picture of your design intention. It might be that you are looking for an hinge connection/rigid. PointConnection can be a solution. Just be careful in reading the structural behaviour. 
I have found a documentation about point connection in FEM-Design wiki.
Hi again @MarcoPelle !
I used the PointConnection for the case. However, I experience that only one of the connections actually are working as wanted. Do you have any idea why it doesn’t work?
Connection 1 (not working):
Connection 2 (working):

The issue is more likely in the data structure of your input.
You might need to use some DataTree to create your PointConnection object. Check how many PointConnection output you are getting in the output component.
In order to help you, I would need your script or a sliced of it.
Thanks! Here is the file!

ehi @perbhagen
You should provide us a minimal script where only the issue arise. In your case, we would like to get only the points and elements that you are trying to connect. We can not deal with huge scripts and find out where the issue happen .
