Description
See http://3mf.io/3mf-version-1-1-is-here/ for the details, but all in all nothing major has changed, so 1.0 and 1.1 can be used interchangably,
Changes are as follows:
- Page 13: Restriction to absolute paths within the package. This was already true in the XSD schema, but is now reminded in the text.
- Page 15: Restricted XML content to UTF-8 to simplify parsers. We added a reminder of how XML namespace inheritance works.
- Pages 25-28: Added object type “solidsupport,” which like a model, must be manifold (hence solid). Objects of type “support” are not intended as solid objects, but as thin walls (regardless of whether they are manifold or not) to be manufactured at the machine’s precision. This ensures no ambiguity in whether support structures should be filled or not.
- Page 31: Restriction that base materials cannot form gradients, in order to ensure that splitting edges in a core-spec 3MF still results in a core-spec 3MF, rather than requiring composite materials from the materials and properties extension.
- Page 46: The only change to the XSD schema is to add “solidsupport.”
