Split at Isocurve

The Split command divides objects into parts using other objects as cutters.

Use Untrim to remove a trimming boundary from a surface.
When you split a surface with a curve in a plan parallel view like the default Top, Front, and Right view, the cutting curve is projected on the surface in the view direction.
When you split a surface with a planar curve in an angled parallel or a perspective view like the default Perspective view, the cutting curve is projected on the surface in a direction perpendicular to the curve plane.
When you split a surface with a 3-D curve in an angled parallel or a perspective view, the cutting curve is pulled onto the surface by closest points.

Command-line options
Point (curves only)	Pick locations on the curve.
Isocurve (surfaces only)	Split an object by its own isoparametric curves. This option only appears when a single surface is selected. Use the Int object snap for snapping to isoparametric curves intersections. Direction U Splits a surface with isoparametric curves in the surface u direction. V Splits a surface with isoparametric curves in the surface v direction. Both Splits a surface with isoparametric curves in both u and v directions. Toggle Toggles the direction between u and v directions.
Shrink (surfaces only)	Determines whether or not the resulting underlying untrimmed surface shrinks close to the trimming boundaries similar to the ShrinkTrimmedSrf command.
SubCrv	Type subcrv to select part of a curve as input.
