Bug Report - Export as 3D Format - OBJ - Y/Z Up is flipped.

Hi,

Not sure if this is the correct place to report bugs but here we go.

When export as obj 3d format by default GM exports as Z up, however looking the obj file it's actually Y up.

If you select 'Export as Y-up' it actually exports as Z up again looking at the obj file.

This is v26.1.1 and it exists as far as v19.

It should be a quick fix.

Thanks

    I think this might just be a difference in nomenclature. In GM, a Z coordinate represents elevation and is 'up', while XY are easting/northing (longitude/latitude). In 3D model formats like OBJ, Y means vertical/up, and X and Z represent the other axes.

    So if you are used to thinking of the axis names in a 3D model space vs. a GIS space, the Y and Z axes might seem flipped.

    Thanks,
