I was thinking it was an DraftView/ArchView, which is just an Svg symbol to us.
We could try to add something that draws a bubble & number if a Source object is an Arc.something, but I don't know enough about Arch to identify an Arch.something.

The bubbles would have to be handled like section lines or detail highlights that get drawn over the basic geometry.
