You use the Piping > Piping Specifications > Model Rules > Pipe Bend Radius Multiplier Rule node in the Catalog tree view to specify the absolute bend radius value for pipe bends based on the nominal piping diameter and the pipe bend radius multiplier as specified in the piping commodity filter. Specifying the bend radius multiplier independently of the commodity option assumes that the bend radius is the only type of option ever required for change-of-direction fittings.
Nominal Piping Diameter (Required)
Type the nominal pipe diameter for which you want to define bend radii.
Nominal Piping Diameter Units (Required)
Specify the units for the NPD column. For example, type mm or in. If the Nominal Piping Diameter Equivalence rule exists in this Piping Specification, the data for this rule is determined by the nominal piping diameter in the primary system of units, which is represented by the active size defined by the piping designer in the 3D model. Or the data for this rule is determined by of the nominal piping diameter in the secondary system of units, as defined by the Nominal Piping Diameter Equivalence rule, if data has not been defined for the value of nominal piping diameter in the primary system of units.
Pipe Bend Radius Multiplier (Required)
Type the pipe bend radius multiplier for which the absolute pipe bend radius applies.
Absolute Pipe Bend Radius (Required)
Type the absolute radius for a pipe bend.
