pymel.core.modeling.detachSurface

detachSurface(*args, **kwargs)

The detachSurface command detaches a surface into pieces, given a list of parameter values and a direction. You can also specify which pieces to keep and which to discard using the -kflag. The names of the newly detached surface(s) are returned. If history is on, the name of the resulting dependency node is also returned. You can only detach in either U or V (not both) with a single detachSurface operation. You can use this command to open a closed surface at a particular parameter value. You would use this command with only one -pflag. If you are specifying -kflags, then you must specify one, none or all -kflags. If you are specifying all -kflags, there must be one more -kflag than -pflags.

Flags:

Long name (short name)		Argument Types	Properties
caching (cch)		bool
	Modifies the node caching mode. See the node documentation for more information. Note:For advanced users only.
constructionHistory (ch)		bool
	Turn the construction history on or off
direction (d)		int
	Direction in which to detach: 0 - V direction, 1 - U direction Default:1
keep (k)		bool
	Keep the detached pieces. Default:true Advanced flags
name (n)		unicode
	Name the resulting object
nodeState (nds)		int
	Modifies the node state. See the node documentation for more information. Note:For advanced users only. Common flags
object (o)		bool
	Create the result, or just the dependency node
parameter (p)		float
	Parameter at which to detach. Default:0.0
replaceOriginal (rpo)		bool
	Create in place(i.e., replace) Flag can have multiple arguments, passed either as a tuple or a list.

Derived from mel command maya.cmds.detachSurface

Example:

import pymel.core as pm

pm.detachSurface( 'surface1', ch=True, d=1, p=0.3, rpo=False )
pm.detachSurface( 'surface1.u[0.3]', ch=True )
# Detaches surface1 into two pieces at u = 0.3.
# The results are two surface pieces, and a detachSurface dependency node.
# Since no "-keep" flag is used, all pieces are kept.

pm.detachSurface( 'surface1', ch=True, k=(1,0), rpo=False, p=0.34, d=0 )
pm.detachSurface( 'surface1.v[0.34]', ch=True, k=(1,0), rpo=False )
# Detaches surface1 at v = 0.34.  Because of the "k" flags, two
# surfaces are created but the second surface is empty.  A
# detachSurface dependency node is also returned.

pm.detachSurface( 'surface1', ch=True, rpo=True, p=(0.2, 0.5), d=1 )
pm.detachSurface( 'surface1.u[0.2]', 'surface1.u[0.5]', ch=True, rpo=True )
# Detaches surface1 into three pieces.  Because of the "-rpo" flag,
# the first surface piece is used to replace the original surface1.
# The results are the three surfaces (including the original surface).
# Even though the "ch" flag is on, a dependency node is not created
# if surface1 is not a result of construction history.  If surface1
# is the result of construction history, then a dependency node is
# created and its name is returned.

pm.detachSurface( 'cylinder1', ch=True, d=0, p=0.3, rpo=False )
# Detaches cylinder1, which is periodic in V, where the V parameter
# ranges between 0.0 and 8.0.  The parameter, 0.3, is used to move
# the start point of the cylinder, also known as the "seam".
# The resulting surface's V parameter range is 0.0 to 0.3.

pm.detachSurface( 'cylinder1', ch=True, d=0, p=(0.3, 0.7), rpo=False )
# Detaches cylinder1, which is periodic in V, where the V parameter
# ranges between 0.0 and 8.0.  The 1st parameter, 0.3, is used to move
# the start point of the cylinder, also known as the "seam".
# The second parameter, 0.7, is used to detach the cylinder again.
# The result is only TWO surfaces; the first surface's V parameter ranges
# from 0.0 to 0.3. The second surface's V parameter ranges from 0.3 to 0.7.
