Create a straight line in planar or non-planar 3D space. The line can be free in 3D space, tangent to a source curve,
perpendicular to a source curve, normal to the plane in which a source curve lies, fixed to a source curve at one
end, or combined with a source curve. The source curve can be an individual curve or the edge of a surface.
Create trimmed curves by using a set of tool curves to split a set of target curves, keeping only the desired pieces.
You can use this tool to split one self-intersecting curve into multiple pieces.
Create an object containing the section curves of a NURBS surface object. You can specify the direction and the position
of the section planes as well as the number of the planes and the distance between them. This modeling tool maintains
construction history.
Extract isoparametric curves from a surface in the U or V direction. This is useful for creating trim curves that
run along a surface but are not attached to it.
