If you have measurements in a .vit file, you will need a new measurements file. Since you are specifically designing this pattern for standard measurements, you should be using a Multisize, .vst, measurement file.
I’m not sure what the numbers in the Base size field are supposed to be referring to, but they are merely affixed numerical identifiers for size variation, you can decide what sizes they refer to yourself.
Or, yes, you could just use a different individual measurement file for each of the standard measurements, & go to the Measurements menu & Load Individual every time you want to use a different standard size.
