Question about trouser figuration from video 17 on men's bespoke trouser making series

Thank you for this link. I was able to download it and I did read that section. It doesn't go into great detail and it doesn't address the "closed leg" figuration that Rory mentions. It seems the older books are better than anything new I can find but they still don't have a lot of information when it comes to trousers. I also have "Tailoring Suits the Professional Way" by Clarence Poulin and it is good but does not get into figuration in pattern drafting or how to correct much. I'll continue to look around. Hopefully Rory will publish his book sometime soon and it will have all the answers to my questions.

Thanks again Gerry

@asherlevikellogg Neither Thornton nor Poulin go into detail because each case will be different. The basic approaches are right though.

If I were doing a pattern for knock-knees, for example, I'd take frontal photos, import them into a graphics programme, draw straight lines from joint-to-joint, lose the original photo and measure the angles of the lines, or the distance/deviation from the centre line. Transfer the results to the draft. You could do this just as easily with tracing paper and a photo print out. This sort of thing (11:15 mins onwards):

As for 'closed leg' vs 'open leg', I think this refers to 'stance', as mentioned earlier: how close the feet/knees are to each other when standing normally. And the calculations are given by Rory in the vid. That's just my interpretation, though.
