The Split command divides objects into parts using other objects as cutters.
Note
- 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.
-
To split a polysurface in a non-plan view, if the cutting curve has any portion evaluated as not completely lying on the polysurface, the Split command will fail as designed.
Steps
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
Determines whether or not the resulting underlying untrimmed surface shrinks close to the trimming boundaries similar to the ShrinkTrimmedSrf command.
EdgeLoop (SubD only)
Separates a SubD along the selected edges.
Steps
- Select a SubD.
- Select edges on the SubD to split.
ShareCorners
Specifies if new corner vertices will be creased.
