I don’t believe this exists - if it does it’s a custom node in a package I don’t have much experience with. Instead, try this:
- Find the line in Dynamo
- Find the intersecting point.
- Split the line at that point - you should now have two lines in Dynamo.
- Set the location of the pipe to the first line in the list.
- Create a new pipe along the second line.
Several example threads exist on this, but I prefer this one: Split Geometry At a given length - #4
