Hi Martin,
The origin of coordinates in the 3MF space doesn’t not necessarily be printable. A specific consumer or printer could decide which volume is visible or printable. So the drawing below still makes sense the 0,0,0 is not printable, the printable volume is inside. Same would happen for example if it were a box where the printable volume started at 5,5,5 mm from the 3MF origin.
Regards Jordi

It's not quite clear how to interpret https://github.com/3MFConsortium/spec_core/blob/master/3MF%20Core%20Specification.md#31-coordinate-space for non-rectangular build platforms, e.g. circular or elliptic.

As the spec already defines the "bottom-front-left corner" as the start of the coordinate system for machines with a box shaped space, I think in order to keep it similarm that the first option would be the more sensible one
