Description
Will produce a cutline from a grid or polydata set.
Arguments
x | y | z axisvalue
Cut with a plane crossing x | y | z axis.
nor n1 n2 n3

ref
Cut through the reference point.
cur

scaon
Generation of cut scalars.
scaoff
No generation of cut scalars.
clean tolerance

Examples
Ex.1: Cutting a grid crossing x axis
win demo ;# Get demo window (450000 460000 6450000 6460000 1000 4000)
spe bgc whi ;# Specify background color to white
mak ran 11 ;# Make 11 random points
grp 222 222 ;# Make grid of dimension 222 x 222
map ;# Map the grid
ctp x 453000 ;# Cut the grid crossing x axis at 453000
col bla ;# Black color
pol 2 ;# Draw cut line with line width 2
The above example produces this image.
