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.
