Extract Cage Polyline

The Extract Cage Polyline command lets you extract cage polylines from an existing curve or face edge from outside a subdivision feature.

  • Each linear section is one polyline segment.

  • A non-linear section is broken into as many linear segments as you specify.

In the example above, a polyline is extracted from sketch geometry, then revolved to create a bottle.

Why should I use it?

Use the Extract Polyline command to create polylines from non-cage geometry. The extracted polylines are then used to generate cage geometry using Extrude Cage, Revolve Cage, Loft Cage, Sweep Cage, or Tube Cage.
