Requirements to objects of splitting |
Scroll |
Sectioning objects should uniquely determine the splitting line, that is, they should cross the entire sectioned surface.
|
In case of a faceted split surface, the splitting line is also considered fully defined if the sectioning object crosses just one or several faces (as opposed to the entire surface) but so that the terminal points of the intersection line would be located on the edges of these faces. In this case, only these faces will be split. |
The objects that may be used as sectioning objects for surface division are shown in the table.

Notes on operation |
|
Coordinate plane or construction plane; face |
•Splitting is made by the line of intersection of the plane or face with the surface being split. •You can use an arbitrary set of planes and/or faces. |
|
Surface; solid |
•Splitting is made by the line of intersection of all the sectioning surface or solid faces with the surface being split. •You can use an arbitrary set of surfaces and/or solids. |
|
|
The notes on using and specifying surfaces and solids in the splitting operation are the same as in the operation of surface trimming. |
|
Curve on the surface being split |
•Splitting is by the curve. •You can use an arbitrary set of curves. •Curves may intersect each other but may not self–intersect. •Use curves with subordinate curved objects has specifics. |
|
Sketch |
•Splitting is made by the line of intersection of the surface being split with the surface generated by extrusion of the sketch in a perpendicular direction to its plane. •You can use just one sketch. •Objects of the sketch may form an arbitrary number or closed and/or open contours. Contours may intersect each other but may not self–intersect. |
