Yes, at a point, we were trying to get the list of codes a little shorter and I think it was decided that the women’s Bust or HighBust measurement could double up as the men’s chest measurement.
Once again, we enter into the troubled pattern making system dilemma because in some pattern making systems, the high bust measurement is called the chest measurement and I think this played a role in the decision.
To tell you about the ‘Men’s Section’, these are mostly measurement areas unique to the older methods for making patterns for men’s suits that are still used today for really high-end bespoke suits and costumes for film & theatre.
I have a work-around where I open my already created measurement file and just change the values for the next person and save it to that person’s name.
I use the Variables Table for the proportional formulas and I’ve also been thinking about using the 8/9 head theory for height measurements, just to check it out, but I’ve been a bit lazy since I made my basic tables that work beautifully 
I would suggest that you enter an average height into the Height measurement that you can change once you have the person’s height.
Hint:
Once you have your pattern created, you can always create a new individual measurement file and import all the measurements used in the pattern. You can import them by going to Menu > Measurements > Import from a Pattern. You will then need to point to the pattern that you wish to import from (the pattern needs to be closed in Seamly2D). All values will be zero, even the formulas, so you will need to enter them.
