Hi @Japhy … This might also help understand the reasons for wanting to manipulate analytical lines in Revit.
There are 3rd Party Tools that read/export from Analytical line models in Revit to Structural analysis models.
Would be great to fix structural beam nodding… Start & End points of columns / beams to have them node before using such 3rd Party Plugins.
