BENDRADIUS

Function:

Specifies when radii of pulled bends will be shown on drawings and in what units.

Description:

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 (for example, 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 (that means, in distance units or in pipe diameters).

A note giving the value of the standard radius can be positioned on the sheet using the POSITION command. The usual method is to plot a suitable message, such as:

All pulled bends to be D unless otherwise shown

as part of an underlay (see the UNDERLAYPLOTFILE command). Then use the POSITION command to create text giving the actual radius value in the space immediately before the D.

You can also include a table of bending data on the isometric using the POSITION command (see POSITION BENDTABLE command for further information).

Examples:

BENDRAD DEFAULT
BENDRAD

All bend radii to be shown in current distance units (no standard value).

BENDRAD STAND 200

Bend radii to be shown in mm, but only if not equal to 200mm (assumes current distance units are mm).

BENDRAD DIAM

Bend radii to be shown as multiples of pipe diameters.

BENDRAD OUTDIAM

Bend radii to be shown as multiples of pipe outside diameters.

BENDRAD STAND 5 DIAM

Bend radii to be shown as multiples of pipe diameters, but only if they do not equal 5 diameters.

BENDRAD OFF

No bend radii to be shown on the drawing.

BENDRADIUS STANDARD 5D
POSI BENDRADIUS AT X200 Y50

Standard bend radius note output at specified position. Only non-standard radii output on isometric. Both standard note and non-standard radii output in multiples of pipe diameter.

BENDRAD STAN 1000
POSI BENDRAD AT X200 Y50

Standard bend radius note output at specified position. Only non-standard radii output on isometric. Both standard note and non-standard radii output in current distance units (mm or inch).
