Spline(bpy_struct)

base class — bpy_struct

class bpy.types.Spline(bpy_struct)

Element of a curve, either NURBS, Bezier or Polyline or a character with text objects

bezier_points

Collection of points for Bezier curves only

character_index

Location of this character in the text data (only for text curves)

Type: int in [0, inf], default 0, (readonly)

hide

Hide this curve in Edit mode

Type: boolean, default False

material_index

Material slot index of this curve

Type: int in [0, 32767], default 0

order_u

NURBS order in the U direction (for splines and surfaces, higher values let points influence a greater area)

Type: int in [2, 6], default 0

order_v

NURBS order in the V direction (for surfaces only, higher values let points influence a greater area)

Type: int in [2, 6], default 0

point_count_u

Total number points for the curve or surface in the U direction

Type: int in [0, inf], default 0, (readonly)

point_count_v

Total number points for the surface on the V direction

Type: int in [0, inf], default 0, (readonly)

points

Collection of points that make up this poly or nurbs spline

Type: SplinePoints bpy_prop_collection of SplinePoint, (readonly)

radius_interpolation

The type of radius interpolation for Bezier curves

Type: enum in [‘LINEAR’, ‘CARDINAL’, ‘BSPLINE’, ‘EASE’], default ‘LINEAR’

resolution_u

Curve or Surface subdivisions per segment

Type: int in [1, 1024], default 0

resolution_v

Surface subdivisions per segment

Type: int in [1, 1024], default 0

tilt_interpolation

The type of tilt interpolation for 3D, Bezier curves

Type: enum in [‘LINEAR’, ‘CARDINAL’, ‘BSPLINE’, ‘EASE’], default ‘LINEAR’

type

The interpolation type for this curve element

Type: enum in [‘POLY’, ‘BEZIER’, ‘BSPLINE’, ‘CARDINAL’, ‘NURBS’], default ‘POLY’

use_bezier_u

Make this nurbs curve or surface act like a Bezier spline in the U direction (Order U must be 3 or 4, Cyclic U must be disabled)

Type: boolean, default False

use_bezier_v

Make this nurbs surface act like a Bezier spline in the V direction (Order V must be 3 or 4, Cyclic V must be disabled)

Type: boolean, default False

use_cyclic_u

Make this curve or surface a closed loop in the U direction

Type: boolean, default False

use_cyclic_v

use_endpoint_u

Make this nurbs curve or surface meet the endpoints in the U direction (Cyclic U must be disabled)

Type: boolean, default False

use_endpoint_v

Make this nurbs surface meet the endpoints in the V direction (Cyclic V must be disabled)

Type: boolean, default False

use_smooth

Smooth the normals of the surface or beveled curve

Type: boolean, default False

calc_length(resolution=0)

Calculate spline length

Parameters: resolution (int in [0, 1024], (optional)) – Resolution, Spline resolution to be used, 0 defaults to the resolution_u
