- Open the motor example. Use the library search to find a pressure gauge, click it, then click the canvas to place it.
- Click the gauge port and then P1.P to make a branch. All links meeting the same port share a pressure node; line crossings alone do not.
- Drag the gauge to move it. Use Rotate or the R shortcut; connectivity remains attached to the original port.
- Shift-click multiple components, then duplicate them. Connections inside the copied group are retained.
- Delete an unwanted line by selecting it. Undo restores the graph. Run design checks to find any open ports.
The checklist records your learning progress. It is not an engineering acceptance test.
