For quality in higher education, it is very important that information contained in textbooks should be clear and free from erroneous statements. In relation to the concept of preliminary gradeline projection (also known as zero line), this paper aims to debug a number of misunderstandings that are come across frequently. It is therefore argued that drawing a horizontal line normal to the baseline of the earth-grade to hit the original ground (for both cut and fill) and naming it as one of the points of the Preliminary Gradeline; and calling the lower grounds in the perpendicular direction from the Preliminary Gradeline as cut and higher grounds as fill are incomplete statements. Corrected versions of these statements are provided in the paper.
