Description

The Curves Interpolate tool interpolates points with a B-spline curve.

Unlike the Curves Approximate tool, which aims to create as smooth a curve as possible by deviating from the points up to an approximation distance, it aims to generate a curve passing through all points.

Usage

1. Select several vertices or one object containing at least 2 vertices.
2. There are several ways to invoke the tool:
   • Press the Interpolate button.
   • Select the Curves → Interpolate option from the menu.
3. An Interpolation_Curve object is created.

Properties

See also: Property editor.

An Interpolation_Curve object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

General

• DataCustomTangents (Bool): User specified tangents.
• Data (Hidden)DetectAligned (Bool): interpolate 3 aligned points with a line.
• DataPeriodic (Bool): Set the curve closed.
• Data (Hidden)PointList (LinkSubList): Point list to interpolate.
• DataPolygonal (Bool): interpolate with a degree 1 polygonal curve.
• DataSource (Link): Source object that provides points to interpolate.
• DataStartOffset (Integer): Offset the start index of the point list.
• DataTangentFlags (BoolList): Activation flag of tangents.
• DataTangents (VectorList): Tangents at interpolated points.
• DataTolerance (Float): Interpolation tolerance.

Parameters

• Data (Hidden)Parameters (FloatList): Parameters of interpolated points.
• DataParametrization (Enumeration): Parametrization type.
  • ChordLength (default): ...
  • Centripetal: ...
  • Uniform: ...
  • Custom: ...
• DataWireOutput (Bool): outputs a wire or a single edge.

Spiral

• DataFaceSupport (LinkSub): Face support of the spiral.
• DataUTurns (Integer): Number of turns between 2 points, in U direction.
• DataVTurns (Integer): Number of turns between 2 points, in V direction.
