By default, bend radii will be output in distance units for all pulled bends, that is for all components with SKEYs beginning with PB. The radii of pulled bends are extracted from their RADI attributes. If the RADI attribute is set to zero and the SKEY is of the format PBnD where n is an integer (e.g. PB5D), then the integer will be extracted, multiplied by the pipe diameter, converted to distance units if appropriate, and output as the bend radius.

Bend radii can be shown either in distance units or as multiples of pipe diameters (where pipe diameter is taken as the nominal bore or outside diameter of the pipe). The Atexts associated with the output of bend radii are Atext 337, ‘D BEND RADIUS’ (for bend radii in multiples of pipe diameters), and Atext 338, ‘BEND RADIUS’ (for bend radii in distance units). Setting either of these to be blank causes the entire message to be suppressed, including the actual radius value.

A standard radius for bends can be set using the BENDRADIUS STANDARD command. If a standard radius is set, only bends which have radii different from the standard radius will have their radii shown individually. Both the standard radius and any individual radii will be shown in the same format (i.e. in distance units or in pipe diameters).
