Splits up a polygon into two or more faces inserting an edge between two points defined by the user. The split command operates in sequential way; the last inserted edge defines the beginning of the next edge.
How to use
1. Select a polygonal model (to convert a NURBS surface into a polygonal one, refer to the PolyMesh from NURBS or PolyMesh from NURBS control net modeling tools).
2. Click the Split Polygon icon or choose the Tools > PolyMesh > Split Polygon command.
3. An alert panel warns you: The selected PolyMesh is part of a Construction Tree. In order to edit with this Modeling Tool, the PolyMesh needs not to be a part of the Construction Tree. Do you want the PolyMesh to be set as hidden and a copy to be created for editing?
Note: If you have previously used the PolyMesh editing tool, the program will not prompt you as the Construction Tree has already been broken.
4. If you click Yes, a new polygonal model with the same shape of the selected one is created.
5. You can split edges that turn blue by clicking on them. Red edges cannot be split.
To end splitting, click anywhere in the view or press the Esc key. To start a new split, choose the New split button.
