Sewing Migration on a New Sewing Feature

This task will show you how to use the new interface of sewing without intersection.

Before you begin:

The creation of a SewSurface in PartDesign offers 2 modes:


  • Intersection (IntersectSewing mode)
  • No Intersection (NoIntersectSewing mode) if topology simplification has been chosen.

The goal of this functionality is to advise the user that the "No Intersection" mode is the only one for sewing creation, with an export. In previous version, an environment variable was also provided to activate this mode:

set SewingNoIntersect=1

It is no more useful now, because it is the default mode.

  1. Open a model.



  2. You can apply a Specification Check on the model and double-click on the Solid in the Check validity dialog box to see the Sewing component:



  3. Copy and Paste Special the Model into another 3D Shape document using the CATIA_SPEC option and update your document to compute the geometry.



    SewSurface.1 is present in the specification tree in CATIA V6. If you double-click it, you can edit this component. By default, the Intersection option is not checked.
