intersect( [surface] [surface] , [caching=boolean], [constructionHistory=boolean], [curveOnSurface=boolean], [firstSurface=boolean], [name=string], [nodeState=int], [object=boolean], [tolerance=linear])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

intersect is undoable, queryable, and editable.

The intersect command creates a curve on surface where all surfaces intersect with each other. By default, the curve on surface is created for both surfaces. However, by using the -fs flag, only the first surface will have a curve on surface. Also, the intersection curve can be created as a 3D curve rather than a curve on surface.

Return value

string[]Object name and node name

In query mode, return type is based on queried flag.


curveOnSurface, duplicateCurve, projectCurve


caching, constructionHistory, curveOnSurface, firstSurface, name, nodeState, object, tolerance
Long name (short name) Argument types Properties
firstSurface(fs) boolean queryedit
creates a curve-on-surface on the first surface only or on all surfaces (default)
tolerance(tol) linear createqueryedit
Tolerance to fit to.
Default: 0.01
Advanced flags
caching(cch) boolean createqueryedit
Modifies the node caching mode. See the node documentation for more information.
Note: For advanced users only.
nodeState(nds) int createqueryedit
Modifies the node state. See the node documentation for more information.
Note: For advanced users only.
Common flags
name(n) string create
Sets the name of the newly-created node. If it contains namespace path, the new node will be created under the specified namespace; if the namespace does not exist, it will be created.
constructionHistory(ch) boolean create
Turn the construction history on or off
object(o) boolean create
Create the result, or just the dependency node
curveOnSurface(cos) boolean create
If possible, create 2D curve as a result

Flag can appear in Query mode of command Flag can have multiple arguments, passed either as a tuple or a list.

Python examples

import maya.cmds as cmds

# Intersect the two active surfaces and create the resulting curve on
# surface as a 3D curve (note: only one 3D curve is created for each
# pair of intersecting surfaces):
cmds.intersect( cos=True )

# Intersect the nurbs sphere and nurbs plane, creating a curve-on-surface
# on each surface:
cmds.intersect( 'nurbsSphere1', 'nurbsPlane1', fs=True )
