Figure 7-1 missing out of the PDF

[mvergall]

Hi, On page 61 of the PDF book there is a reference to a Figure 7-1 but the figure is missing...could you please fix this because without this figure the rest of that chapter is unreadable also the drawing itself is not included so the whole further exarsice becomes impossible to follow

Figure 7-1 is on page 55, the overview of snap tools.
