Split

Use the Split tools to split a cage with a loop or split a single PolyNURBS cage face.

Split Cage with Loop

Draw an edge loop around a cage, subdividing the PolyNURBS object to gain more control when editing the cage.

  1. On the PolyNURBS ribbon, select the Split Cage with Loop tool.
  2. Click the edge of an existing cage to create a loop perpendicular to that edge. Mouse over an existing edge to preview the loop.
    The loop is created at the point where you clicked.
  3. Optional: To reposition the loop:
    • Drag the loop.
    • Hold down Ctrl while clicking the loop, and then use the graphic manipulators.
  4. Right-click and mouse through the check mark to exit, or double-right-click.

Split Faces

Split a single PolyNURBS cage face.

  1. On the PolyNURBS ribbon, select the Split Faces tool on the Split icon.
  2. Click a point on one edge where you want to split the face.
    Tip: Hold down the Alt key to temporarily disable snaps.
  3. Click a second point on one of the face's other edges to split the face.
  4. Right-click and mouse through the check mark to exit, or double-right-click.
