How can we run fill-aware PEX?

How can we perform fill-aware PEX? I inserted fills and extracted the SPEF file, but there was no noticeable difference between the SPEF files before and after fill insertion. How can I properly set up the extraction process to account for inserted fills?

dbShape with type=FILL

[maliberty]

dbShape is not a persistent class so how they actually be stored?

[dimitrisfotakis]

dbShape can be generated by dbWire class.
did you add dbFill objects in the rcx geometry data structures?

[dimitrisfotakis]

another possibility is to use dbSBox (persistent object used for supply nets) to hold the fill wires

[maliberty]

Regardless of storage mechanism, is there any modeling in RCX? You can't just treat it like a wire.
