Duct Size Options
Once the Duct Size Options have been configured, users may place ducts within ducts in ArcFM.
To place ducts within ducts, it is necessary to have a field in the duct definition object class with a model name of DUCTSIZE. This field model name is used to determine at what size ducts are plotted in map units (or another unit of measure; see note). The duct size field may be assigned a custom editor that restricts the values of the size field so users cannot select a duct that is equal to or larger than the master duct.
