How do you xxplain the problem that will be created if you mark the original baseline with a washable felt-tip pen instead of a pencil?
Using a washable felt-tip pen instead of a pencil to mark the original baseline can cause the ink to bleed or smudge when exposed to moisture or handling. This can lead to inaccuracies in measurements or project alignment. Additionally, the ink may fade over time, making it difficult to refer back to the original baseline.
