Which method for placing sample lines along an alignment involves picking points on the screen?

• A. By Range of Stations
• B. At a Station
• C. Pick Points on Screen
• D. From Corridor Stations

Answer: (C)

Placing sample lines by picking points on screen is the interactive approach that lets you define where a cross-section sits directly in the drawing. You click specific points on the plan or alignment to set the sample line’s location, which is useful when the desired position corresponds to a feature or geometry you can see rather than a defined station value. The other methods rely on numeric inputs: Range of Stations uses a start and end station range; At a Station places the sample line at a specific station; From Corridor Stations uses positions derived from corridor data. So picking points on screen is the option that uses on-screen clicks to determine placement.
