Extract the 2D or 3D silhouette curve of one or more selected objects while maintaining construction history.

  1. On the ribbon, click the Curves tab.
  2. Click the Silhouette icon.

  3. Select one or more objects. Right-click to confirm.
    By default, a 2D silhouette curve is created within the x-z plane.
  4. Optional: Define the output type:
    • Planar Output: Extract a 2D silhouette curve.
    • 3D Output: Extract a 3D silhouette curve.
    Note: Double-click the curve to edit.
  5. Optional: You can adjust the direction of the silhouette curve by selecting one of the following options:
    • Global X Axis: Lock the x direction, so that the silhouette curve is in the y-z plane.
    • Global Y Axis: Lock the y direction, so that the silhouette curve is in the x-z plane.
    • Global Z Axis: Lock the z direction, so that the silhouette curve is in the x-y plane.
    • Custom: Set the silhouette curve in a custom direction by dragging the Phi angle arrow or the Direction point. This may affect the shape of the silhouette curve.
    • Set as Current View: Position the silhouette curve along the axis that is perpendicular (normal) to the active modeling view.
  6. Optional: You can move the silhouette curve:
    • To snap the origin to another object, drag the Origin point.
    • To move the plane of a 2D silhouette curve, drag the Move projection plane point.
  7. Right-click and mouse through the check mark to exit, or double-right-click.
