Description

Girths may be calculated and output for any stored curves between any two limits. The limits may just be the start and end of the curve ( the default ) or they may be defined by the user with the /LOWER and/or /UPPER options. The output is normally listed to the screen but may be sent to a file by use of the /FILE option.

Command Qualifiers

/X

Girth calculated between two X values.

/Y

Girth calculated between two Y values.

/Z

Girth calculated between two Z values.

/LOWER=$N

Defines the lower value for which the girth should be calculated.

/UPPER=$N

Defines the upper value for which the girth should be calculated.

/BUFFER

If the POINTS or SPACING option has been given, then the generated points will be added to the Points Buffer.

Examples

GIRTH SECTION /ALL /Z /LOWER=1 /UPPER=6
GIR PLI po1 /X /LOW 25 /UPP 45 /BOTH
GIR WAT 2 THR 6 .5 /X /LOW 10 /UPP 89.5
