sa

The sa setting controls the seam allowance. Either provide value in millimeter or set it to false or 0 to disable seam allowance altogether.

Setting a seam allowance causes the pattern to be generated with additional lines so pattern pieces can be cut out with the correct seam allowance included.

Signature

const settings = {
  Number|Boolean sa=false
}

By default, the sa setting is false and seam allowance is not included.

Example

import { Aaron } from '@freesewing/aaron'

const pattern = new Aaron({
  sa: 10,
})

Notes

The sa setting does not automatically cause seam allowances to be displayed on a pattern. Instead, it is up to the pattern designer to have the design check for the sa setting and include the appropriate seam allowance lines on the pattern when sa is set to a non-zero numeric value.

Previous versions of FreeSewing were setting sa automatically to 0 to disable seam allowance if settings.complete is false. This doesn't apply anymore.

We recommend only showing the part outline and the seam allowance when sa is nonzero and complete is false. This is what will usually happen anyway if you don't add any special code to handle this case.
