Split Edge

Insert a new vertex along an edge, splitting the edge into two new edges.

This tool is useful when you need to refine the geometry of a PolyNURBS object. Note that this tool permanently modifies the selected object rather than creating a new one, so it does not have construction history.

  1. On the ribbon, click the PolyNURBS tab.
  2. In the Split group, click the Split Edge icon.

  3. Click the PolyNURBS object.
    Edges will be indicated in yellow upon hovering.
  4. In the guide bar, choose from the following options:
    • To create equally spaced snap points along the selected edge, enter a Subdivision Snap value.

      For example, if you want to add a vertex one-quarter of the way along a selected edge, set the Subdivision Snap value to 3; doing so places 3 control points along the edge to create four evenly spaced subdivisions.

    • To add one vertex at each Subdivision Snap point in one click, select Multiple Split.
    Note: By default the subdivision snap is set to 1. This will allow you to snap the vertex to the midpoint on the edge. You can turn the subdivision snap to 0 to disable the midpoint snap.
  5. Click the edge to split, and then (if Multiple Split is not enabled), you can drag the division point to reposition it.
  6. Right-click and mouse through the check mark to exit, or double-right-click.
