| 30 | | 11. Apply orthogonal layout to network: all edges represented by polylines must draw orthogonally. |
| 31 | | 12. Grid layer on/off: a grid overlaying the entire canvas must be switched on/off |
| 32 | | 13. Squiggle layer on/off: with option on and pressed left mouse button, a line is drawn, can be switched on/off |
| 33 | | 14. Status layer on/off: with option on, a text box appears in the left lower corner showing the name of the current scenario and the current navigation mode, can be switched on/off |
| | 30 | 11. Orthogonal layout [[BR]]Apply an orthogonal layout to the network, all edges represented by polylines (not straight lines) must be drawn in an orthogonal style. |
| | 31 | 12. Grid layer on/off [[BR]] A grid overlaying the entire canvas should appear/disappear by switching option on/off. |
| | 32 | 13. Squiggle layer on/off [[BR]] With option on and pressed left mouse button, a line is drawn, release mouse button should stop drawing, drawings can be switched on/off. |
| | 33 | 14. Status layer on/off [[BR]] With option on, a text box appears in the left lower corner showing the name of the current scenario (default: Logical Scenario) and the current navigation mode (default: Hierarchy Zoom), display can be switched on/off. |
