Hi. I want to split mutibeam at multiple points. Can you help me ?
Thanks a lot !!!
Hi @trungdung06n1 …if you want to use custom nodes then try this one here from Genius Loci…i know my example is on duct but should work on beam as well…
Hi. I want to split Beam at Point on Beam. Can you help me? Many thanks.

Yes no worries 
could you share your rvt with these 4 beams…and your graph…arh i see you are new user so just share over webtrans or whatever and give the link here…Btw welcome here

I am using Revit 2023 version.do you use it?
Allright try something here…could probably work for you…

Not sure whats goin on are you try to split in a clash point…i just try to show a rough example how you can split, and there are many ways to generate point i just do it fast that way…but good luck with that

the script has as input a list of beams and an array of array of points (as the @sovitek 's solution), the Curve.PointAtParameter node is just an example to generate points easier.
you need to group your clash intersection points per beam

by this method i couldnt run python script. But i combine this one and the @sovitek 's approach. It works when i try to divide multiple beams by only 1 beam. if there’s 2 more beams to cut with script dont cut all of the ones.
