Creating Curves Using Control Points

Creating 3D Curves

You can create a curve using points or control points positioned in the work area or on a curve.


Before you begin: Open an existing 3D shape.
  1. Select the curve creation type, then select the points.
    • Through points: Creates a multiarc curve passing through each selected point.
    • Control points: Creates a curve with the selected points as the control points.
    • Near points: Creates a single-arc curve with the specified order and smoothed through the selected points.
  2. For the Control Points type, define the Max Order allowing you to specify a bound for the computation of a mono-arc curve.
  3. Move the pointer over a point.
    A handle is displayed allowing you to modify the point location as you create the curve.
  4. Optional: Insert a control point:
    1. Ctrl+A or click Insert a point .
    2. Click the segment between two existing points where you want to add a new control point.
    3. Click at the position where you want to add the control point.
  5. Optional: Click Remove a point and select a point.
  6. Click OK to create the curve.
