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 ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 

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 ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Modifies the node caching mode. See the node documentation for more information.Note:For advanced users only.
close (c) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 

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 ../../../_images/create.gif
 
Turn the construction history on or off
createCusp (cc) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 

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:falseAdvanced flags

degree (d) int ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
The degree of the resulting surfaceDefault:3
name (n) unicode ../../../_images/create.gif
 

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.

nodeState (nds) int ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Modifies the node state. See the node documentation for more information.Note:For advanced users only.Common flags
object (o) bool ../../../_images/create.gif
 
Create the result, or just the dependency node
polygon (po) int ../../../_images/create.gif
 

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 ../../../_images/create.gif
 
Force a curve range on complete input curve
rebuild (rb) bool ../../../_images/create.gif
 

Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.

reverse (r) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 

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 ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
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 ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
The number of surface spans between consecutive curves in the loft.Default:1
uniform (u) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 

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')] #
