#1147 Export/reimport of multiple hinged objects synchronises the hinges

[Stephen]

If I export to obj, objects with multiple copies of the same hinging object, then reimport, the hinges become "sychronised", i.e. opening one element (i.e. a window) opens the others. Further, if the orientation (or maybe position too) is different the hinging becomes unpredictable, with the hinge point changing.

User Keet helped with the explanation to edit the exported obj file to make the sweethome3d_hinge_# and sweethome3d_opening_on_hinge_# unique between the different windows. When exported they are turned into a single object, and reimporting makes the hinge_1 common to all hinge parts.

It would be really good if when exporting multiple objects to a single obj if SH3D could track which hinges (or rails) have already been used. If the number is already in use, get the next free number.

I describe a use case, which I use to create a pitched roof with functional opening windows.
