jeans draft front

So I have drafted the fronts of the jeans, as instructed.

Beginning with the crotch or "fork line", at "0".

0-1 is the rise , less the waistband which I decided was 1 and 1/2 inches deep.

the instructions progress logically until you get to

"draw the fly seam"

Looking at the illustration of the draft makes this instruction confusing.

So I left it for a moment and went to the next few instructions

0-8 to find the hip point

9 from 7 to get the waist point

11 is 1 inch above the fork line and 1/2 inch from the fly seam grow on fly at point 10-11.

Ok so this is irritating.

There is 1/2 inch seam allowance allowed, so you can see the dotted line inside the lower area of the fly line that is drawn from 6 indicating the seam allowance. At 11 it turns abruptly into the solid line from 11 to 10.

10 is 1/2 inch in from 7 so one assumes that is seam allowance.

Then you see the fly line from 6 running into a point above 11 in a small dotted line, that seems to run into the line 10- 11 as well.

It makes it very confusing to determine where the centre front line is if you didn't want a grow on fly.

The abrupt angle formed at 11 isn't pleasing to me either.

I am very opinionated about drafts and I think they should be clear.

This one doesn't get any marks for clarity.

What else can I say at this point? I think that there will need to be some truing up of angles at some point, but I will draft the back next ( I think there is something odd going on there as well), so I'll go onward and try to make sense of it all at the end.
