Synopsis

loft [flags] curve1 curve2 [curve3 ...]

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.

Return value

[string[]] (object name and node name)

Long name (short name)[argument types]Properties
-uniform (-u) booleanqueryedit
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
-close (-c) booleanqueryedit
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
-degree (-d) integerqueryedit
The degree of the resulting surface
Default: 3
-autoReverse (-ar) booleanqueryedit
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
-reverse (-r) booleanqueryeditmultiuse
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) booleanqueryedit
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) integerqueryedit
The number of surface spans between consecutive curves in the loft.
Default: 1
-createCusp (-cc) booleanqueryeditmultiuse
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
-name (-n) stringcreate
Name the resulting object
-constructionHistory (-ch) booleancreate
Turn the construction history on or off (not available in all commands)
-object (-o) booleancreate
Create the result, or just the dependency node (not available in all commands)
-replaceOriginal (-rpo) booleancreate
Create "in place" (i.e., replace) (not available in all commands)
-curveOnSurface (-cos) booleancreate
If possible, create 2D curve as a result (not available in all commands)
-polygon (-po) integercreate
The value of this argument controls the type of the object created by this operation (not available in all commands) - 0: nurbs surface - 1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion) - 2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion) - 3: Bezier surface - 4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)
-range (-rn) booleancreate
Force a curve range on complete input curve (not available in all commands)
-rebuild (-rb) booleancreate
Rebuild the input curve(s) before using them in the operation. Use nurbsCurveRebuildPref to set the parameters for the conversion. (not available in all commands)

Examples


		//A loft across three curves curve1, curve2, curve3. Curve ranges
		//have been enabled on the three curves. The curves will be reversed
		//internally if needed to avoid a bow tie looking surface.
		loft -ch true -rn true -ar true curve1 curve2 ;

		//A loft across a NURBS curve, surface isoparm and a curve on surface.
		//The curve directions will not be reversed.
		loft -ch true -ar false curve1 surface1.u[1.0] surfaceShape2->curve1 ;
