0 = no action
1 = fix the geometry defects of input curves
if within tolerance, including gap/overlay
between curves and off-planar condition for capping.

the option for enabling open profile smart volume.
When this option is set to true, extends the tool volume
along open end points of the profile to find
closure with the target body.

the option defines how to extend the open profile
to form a proper intersection with the target body.
0 = FCI, Extends the open profile to form
the first complete intersection with the target
1 = LCI, Extends the open profile to form
the last complete intersection with the target
2 = CCI, For subtract boolean operation, extends the open profile
to form the last complete intersection if the profile lies
outside the target excluding the coincident portion.
Otherwise, uses the first complete intersection.
