• You can replace a schematic fitting with another schematic fitting only if schematic fittings are available for the selected pipe segment.

• You can replace a schematic fitting with a nonschematic fitting by clearing the XML File check box in the Replace Fitting dialog box. This is possible even if schematic fittings are available for insertion.

• If no schematic fittings are available when replacing schematic fittings, you can replace fittings in the default nonschematic replacement mode.
