Is it possible to insert a Run between two existing components so that a support can be attached at that location?
Yes, it is possible to insert a Run between two existing components and attach a support to it; however, this requires explicitly rewiring the component chain using link().
By default, when add_run() is called on a component that already has a forward connection, AutoPIPE DataAPI creates a new branch instead of inserting the Run inline. This results in a disconnected topology, and the model fails to save with error E6000: Component disconnected from rest of segment.
You want to add a support between components A04 and A05.
A04S = A04.add_run(name="A04S", segment=seg, pipe_property=pp, offset=(0,10,0))
A04S.add_support(tag_number="VS-001", type=SupportType.VSTOP)
At this point, A05 becomes disconnected from the main segment, which causes model.save() to fail with E6000.
To restore segment continuity, you must explicitly reconnect the newly created Run to the downstream component:
A04S.link(A05) # Reconnect A05 to the segment
