pymel.core.modeling.loft

loft(*args, **kwargs)

This command computes a skinned (lofted) surface passing through a number of NURBS curves. There must be at least two curves present. The NURBS curves may be surface isoparms, curve on surfaces, trimmed edges or polygon edges.

Flags:

Long name (short name)		Argument Types	Properties
autoReverse (ar)		bool
	If set to true, the direction of the curves for the loft is computed automatically. If set to false, the values of the multi-use reverse flag are used instead. Default:true
caching (cch)		bool
	Modifies the node caching mode. See the node documentation for more information. Note:For advanced users only.
close (c)		bool
	If set to true, the resulting surface will be closed (periodic) with the start (end) at the first curve. If set to false, the surface will remain open. Default:false
constructionHistory (ch)		bool
	Turn the construction history on or off
createCusp (cc)		bool
	Multi-use flag; each occurence of the flag refers to the matching curve in the loft operation; if the flag is set the particular profile will have a cusp (tangent break) in the resulting surface. Default:false Advanced flags
degree (d)		int
	The degree of the resulting surface Default:3
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
polygon (po)		int
	The value of this argument controls the type of the object created by this operation 0: nurbs surface1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion)2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion)3: Bezier surface4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)
range (rn)		bool
	Force a curve range on complete input curve
rebuild (rb)		bool
	Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion. Flag can have multiple arguments, passed either as a tuple or a list.
reverse (r)		bool
	Multi-use flag; each occurence of the flag refers to the matching curve in the loft operation; if the flag is set the particular curve will be reversed before being used in the loft operation. Default:false
reverseSurfaceNormals (rsn)		bool
	If set, the surface normals on the output NURBS surface will be reversed. This is accomplished by swapping the U and V parametric directions. Default:false
sectionSpans (ss)		int
	The number of surface spans between consecutive curves in the loft. Default:1
uniform (u)		bool
	If set to true, the resulting surface will have uniform parameterization in the loft direction. If set to false, the parameterization will be chord length. Default:false

Derived from mel command maya.cmds.loft

Example:

import pymel.core as pm

# A loft across two curves: curve1, curve2. Curve ranges
# have been enabled on the curves. The curves will be reversed
# internally if needed to avoid a bowtie looking surface.
pm.curve( d=3, p=( (-11, 0, 0), (-13, 0, -4), (-17, 0, -15), (-4.7, 0, -10), (1, 0, -8 ) ) )
# Result: nt.Transform(u'curve1') #
pm.curve( d=3, p=( (-2, 0, 5), (-2, 0, 3), (-2, 0, -1), (4, 0, 0), (7, 0, 0 ) ) )
# Result: nt.Transform(u'curve2') #
pm.loft( 'curve1', 'curve2', ch=True, rn=True, ar=True )
# Result: [nt.Transform(u'loftedSurface1'), nt.Loft(u'loft1')] #
