ARCHICAD 24 improves polyline editing:
•The Intersect command now works between two or more independent Polylines, and between Polyline and Wall/Beam/Line/Arc.
•When intersecting Polylines: if only one ends intersects after the first Intersect command, repeat the command to intersect the other ends as well (this is the same function as for Lines).
•Fillet/Chamfer command now works on Polylines, (If more than one Polyline is selected for this command, first they will be intersected and then filleted or chamfered.)
