Use the Edge Coloring option to distinguish boundary edges:
| By Body Color (default): Displays body colors to represent boundary edges. |
| By Connection: Displays five different colors corresponding to five different categories of connectivity. The categories are: free (blue), single (red), double (black), triple (pink) and multiple (yellow). Free means that the edge is not shared by any faces. Single means that the edge is shared by one face and so on. |
| Black: Turns off the edge/face connectivity display. The entire model is displayed in black. |
