3D Space Frame Top Chord Using Dynamo

#1

Hi,
I am a beginner in dynamo and would like ask you the workflow required to achieve my task.
I have a large sloped roof with space frame. I created the bottom chord and diagonal member chord using Revit curtain panel pattern based family and applied it on the roof surface. But unfortunately I can not create the Top chord member using this work flow. Is it possible to use dynamo to create this top chord member using the central node ?

Hello and welcome to the forum! As a new user, you could need to read this page before getting an answer:


You will probably need to build a first graph based on what is already available online (the search tool on top-right of this screen can help). It will then be possible to get help here on specific issues.
You will also find good basics on these pages:

I wish I could but I don’t have much time at the moment. But maybe someone else could help. Please see also this interesting thread:

Please send some screenshots too, this node shouldn’t be difficult to understand:
