Is it possible to create a model line at the bottom of my pipe using Dynamo?
Yes. Look into Clockwork’s Element.Locaton node.
With element.location from Clockwork or my node from Dynamo4MEP you can easily extract the curve for the pipe or the connector points, then you can translate those points according to the outside diameter of the pipe
How do I find Clockwork’s Element.Location node? I cannot seem to locate it on Dynamo.
You’ve to download the package from the package
