To nest is important that the outer curve of each object is closed. This tool checks if the curves are open or closed, marking where they are open.
RhinoNest > Tools > Check Curves
1. Select the curves to check.
2. Press Enter to confirm.
The result will show how many are open curves and how many are closed. And the open points of the curves as well.
Green Color: Closed Curves.
Red Color: Open Curves.
