Similar to the CUTFORM definition.

method: Controls the form of the cutting body

1:prism shaped

2:pyramidal

3:wedge-shaped cutting body. The direction of the wedge’s top edge is parallel to the Y axis and its position is in rx, ry, rz (ry is ignored).

status: Controls the extent of the cutting body and the treatment of the generated cut polygons and new edges.

status = j1 + 2*j2 + 8*j4 + 16*j5 + 32*j6 + 64*j7 + 128*j8 j1: use the attributes of the body for the generated polygons and edges

j2: generated cut polygons will be treated as normal polygons

j4, j5: define the limit of the cut: j4 = 0 and j5 = 0: finite cut

j4 = 0 and j5 = 1: semi-infinite cut j4 = 1 and j5 = 1: infinite cut

j6: generate a boolean intersection with the cutting body rather than a boolean difference. (can only be used with the CUTFORM command)

j7 : edges generated by the bottom of the cutting body will be invisible j8 : edges generated by the top of the cutting body will be invisible

rx,ry,rz: defines the direction of cutting if the cutting form is prism-shaped, or the top of the pyramid if the method of cutting is pyramidal

d: defines the distance along rx,ry,rz to the end of the cut. If the cut is infinite, this parameter has no effect. If the cut is finite, then the start of the cutting body will be at the local coordinate system and the body will end at a distance of d along the direction defined by rx,ry,rz

If the cut is semi-finite, then the start of the cutting body will be at a distance of d along the direction defined by rx,ry,rz and the direction of the semi-infite cut will be in the opposite direction defined by rx,ry,rz.
