New issue 451: Can’t create even Seam Allowance width with Bias options https://bitbucket.org/valentinateam/valentina/issues/451/cant-create-even-seam-allowance-width-with
In v.0.4.2.0 tried to create a .25cm seam allowance width around a neckline curve. The options in the Seam Allowance tool include a ‘Bias’ offset for x & y values.
The x & y bias values are absolute which may result in an undesired seam allowance width when using other measurement files.
Also requires a calculator to construct an accurate seam allowance width when the seam allowance is neither vertical (90 degrees) or horizontal (180 degrees).
This approach may need additional tweaking or redesign.
