question from page 50 in the book Two-piece Front CT.04
After creating points 13, 13A & 14 there is a line of text that says
" Find point to point measure from pt0 - pt13a and double."
It doesn't say what this computation is used for?
Will it be used later?
It goes on to create points 15,16 etc.
What am I missing here?

Hi Roy
When I did the course I figured that the "Find point to point measure from pt0 - pt13a and double meant that if you measured from Point 0 to 13a and doubled it this would give you the point to point from the body measurement. Though I am not sure why it isnt Point 0 to 13 minus a seam of 10mm and double. Rory may need to answer that
