Creating Parallel Curves

You can create a curve parallel to an existing reference curve.

The new curve is positioned according to a defined offset: it can be the position of a point or a distance.

Important: The reference curve must lie on a support.

  1. In the work area, select the reference elements:
    1. A curve
    2. A support

      The support can be a plane or a surface.

  2. To define the offset of the parallel curve, do one of the following:
    • In the work area, select a point.

      The parallel curve goes through this point.

    • In the Distance box, specify a value.

      The parallel curve is positioned according to the specified distance

      Tips:
      • Click Invert Direction to reverse the direction of the parallel curve.
      • Click Mirror to create two parallel curves: one on each side of the reference curve.

  3. Under Advanced parameters, select a Parallel Mode:
    • Euclidean: The distance between both curves is the shortest possible distance, regardless of the support.
    • Geodesic: The distance between both curves is the shortest possible distance, taking the support curvature into account.
  4. If the selected Parallel Mode is Euclidean, select a Parallel Corner type:
    • Sharp: The parallel curve takes into account the angle in the initial curve.
    • Round: The parallel curve is rounded off as in a corner.
