offsetCurve is undoable, queryable, and editable.

The offset command creates new offset curves from the selected curves. The connecting type for breaks in offsets is off (no connection), circular (connect with an arc) or linear (connect linearly resulting in a sharp corner). If loop cutting is on then any loops in the offset curves are trimmed away. For the default cut radius of 0.0 a sharp corner is created at each intersection. For values greater than 0.0 a small arc of that radius is created at each intersection. The cut radius value is only valid when loop cutting is on. Offsets (for planar curves) are calculated in the plane of that curve and 3d curves are offset in 3d. The subdivisionDensity flag is the maximum number of times the offset object can be subdivided (i.e. calculate the offset until the offset comes within tolerance or the iteration reaches this maximum.) The reparameterize option allows the offset curve to have a different parameterization to the original curve. This avoids uneven parameter distributions in the offset curve that can occur with large offsets of curves, but is more expensive to compute.

Return value

string[]Object name and node name

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

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
range(rn) boolean create
Force a curve range on complete input curve

Python examples

import maya.cmds as cmds

# offset all active curves to the specified distance:
cmds.offsetCurve( d=4.0 )

# create offsets for the specified curve and turn loop cutting off:
cmds.offsetCurve( 'curve1', cl=False)

# create offsets with circular arcs at the breaks in the curve and use
# a cutting radius of 2.0 if there are any loops in the offsets:
cmds.offsetCurve( 'curve1', cb=1, cl=True, cr=2.0 )
