Feature: Custom patternmaking systems - backpack measurements in seamlyme

[bzed]

Maybe a not so usual request, but please support measurements for backpacks - including those nice diagrams - in seamlyme. An example is here: https://leaf.arcteryx.com/us/en/help/sizing/backpacks Thanks a lot!

Not quite sure how this fits in with Seamly2D / SeamlyME... where the "known" measurements included are those used by the various systems to draft a pattern. My understanding is the idea with the known measurements - although not fully implemented yet - is that a user would select a drafting system, and a measurement file with all the needed measurements for that system is automatically created. I'm unaware of any backpack drafting systems? Seems like a very niche market - how useful would these measurements be to the target users?

That being said, I would tend to look at the bigger picture and maybe make a feature where a user can design and add custom measurements to the known list... rather than adding measurements piecemeal.

Hey we can make this happen right now using Seamly's custom Variables feature. The future feature to import/export Variables will make this super-easy for you.

User's custom patternmaking systems are in the want list, but we'll first need to decouple the patternmaking systems from translations.

Current solution:

"1. Back Length: To determine your size, measure down the spinal column from the 7th cervical vertebra and the level of the hip iliac crest. "

• Users enter two measurements: "back neck to back waist length" and "back waist to back highhip length".
  Define the @BackLength variable:
  BackLength = (neck_b_to_waist_back + waist_b_to_highhip_back)

"2. Hipbelt sizing: is based on a measurement around the hip iliac crest. Measure around the body at the top edge of the hip iliac crest, approximately 2 inches below the point at which you would measure your waist."

• Users enter their highhip circumference. Define the @HipBelt variable: HipBelt = (highhip_circ)

"3. Shoulder strap: sizing refers to bust/chest circumference. Measure around the bust/chest at the fullest point."

• Users enter their chest circumference.
  Define the @ShoulderStrap variable:
  ShoulderStrap = (chest_circ)

There's a 4th measurement, the user selects the pack size, either 'Regular' or 'Tall', based on their height

• Users enter their height. Define the @PackSize variable:
  PackSize = ( (height > 50.5) ? "Tall" ; "Regular" ) Formulas can test for value: ( (@PackSize = "Regular") ? (formula1) ; (formula2) )
