Description[edit | edit source]

The Curves ParametricComb tool can help to visualize the regularity or smoothness of a curve as well as the continuity between two curves.

Note: A comb is only for visualization.

A 3D comb will be created for 3D curves. Sample and scale can be changed.

Usage[edit | edit source]

  1. Select one or more shapes (sketch, wire, face, etc.).
  2. There are several ways to invoke the tool:
    • Press the Comb plot button.
    • Select the Curves → Comb plot option from the menu.
  3. A Comb object is created, showing the curvature of the select shapes (sketches, wires), or their sub elements (borders and iso-curves in case of faces).
  4. Optionally edit the values in the Property editor (see Properties below):
    • Adjust the number of samples and the comb scale for all comb plots.
    • Adjust the number of comb plots and their orientation for surface objects.

Notes[edit | edit source]

  • This tool functions as a visual aid.
  • This tool accepts several types of curves, and surface elements, and creates additional iso-curves in U and V direction for the latter.

Properties[edit | edit source]

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

Data[edit | edit source]

Comb

  • DataComb Points (VectorList): Comb Points.
  • DataEdge (LinkSubList): List of input shapes.
  • DataSamples (IntegerConstraint): Number of samples per comb plot.
  • DataScale (Float): Scale (%). 0 for AutoScale.
  • DataShape (PartShape): Shape of comb plot.

Surface

  • DataNumber (Integer): Number of surface samples (comb plots) in U and/or V direction.
  • DataOrientation (Enumeration): Surface Comb Orientation to distribute the surface samples (comb plots).
    • U (default): Displays comb plots along U direction only.
    • V: Displays comb plots along V direction only.
    • UV: Displays comb plots along both directions.
