Revit Dynamo #8.18 Function - Split Ducts and Pipes by Length

[@pedrovizueta2693]

Where can I find this package Worksheet Visibility 11:49

Your demo looks promising and it's nice to walk along with you to learn what every block does or why you use it. But I'm getting stuck when you add Element.CopyByVector. I can't seem to find the block in my library. Could it be that there is a package that I need to load first?

It's in the Clockwork package

Spent some time on this , won’t work. Not sure why

[@kristianbrango7711]

I think its because your model is not workset enabled

[@vuinhduy8314]

for auto split duct, pipe,.. you should better using Python or C#

Yes Looks something like this:

from System import Guid
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *
clr.AddReference('RevitAPI')
