If they allow you to use a pencil, draw the lines. If they don't, you have to practice with the lines prior to the exam as much as you get to a point that you don't need the lines anymore. You imagine them.
For ADEX/CDCA exams, it is allowed to use pencil over the typodont. I meant Bench Test exams, if the program you're applying to allows you to use a pencil. Some do, and some don't.
In the exam how could you do this?
