I think a template properly implemented should allow you to use the term girth or any other term defined in that particular pattern system to map to the known measurement.
@Douglas, that is why I asked you earlier about a written reference for the use of the term girth. I am working on the issue of how to implement templates (and am willing to accept any help or input). Currently as far as I see there is no effect in selecting any pattern system in the preferences.
Here is a current list of the known pattern systems
If one of those does not contain the specific measurements that you need then there are at least two ways to fix it:
- add a patternsystem to the list
- add the ability to create one’s own patternsystem
Personally, I prefer #2 and I believe that instructions and examples need to be provided for creating a new template to define the patternsystem.
@slspencer talked with me about this at length and I have been unable to find any example to prove her wrong. I will try to summarize what she said about measurements and invite her to correct me if I am wrong.
The list of terms used by people to describe body points or measurements between body points is a huge or infinite list. After the study of many pattern making systems, she created the “known measurement” list used in valentina. Templates should be used to present the known terms to a user while there is a finite list of known measurements recognized internally.
Please read the information on the wiki starting at Measurements - Seamly2D
Please pay particular attention to the [https://bitbucket.org/ValentinaTeam/valentina/downloads/measurement-body-points_20170822.svg Body Points Diagram]
If you need a measurement that can’t be expressed as a known measurement, or a formula based on known measurements, please request that one be added.
