For this exercise, the advice is to try to draw the lines in all those directions we mentioned in our first posts. Reminder: d1, d2, vertical, horizontal. Also, the exercise requires an accuracy of the line, so we should be careful and have 3 to 5 lines overlapped almost perfectly, without having too much distance between the lines we want to superpose. Ok? The exercise will help you later, when hatching different objects: when using 45 angle degrees of shading, gradient or intersection shading technique.
