Afterȱplacingȱseveralȱobjectsȱonȱtheȱbuildȱtray,ȱyouȱcanȱletȱObjetȱStudioȱ
arrangeȱthemȱbeforeȱprinting.ȱThisȱensuresȱthatȱtheȱobjectsȱareȱpositionedȱ
properly,ȱandȱthatȱtheyȱwillȱbeȱprintedȱinȱtheȱshortestȱtimeȱandȱwithȱaȱ

To automatically arrange objects on the build tray:
¾
OnȱtheȱTrayȱSettingsȱribbon,ȱclickȱ .

Model Orientation
Theȱorientationȱofȱmodelsȱonȱtheȱbuildȱtrayȱaffectsȱhowȱquicklyȱandȱ

¾ For best results, arrange the tray with Automatic Placement, on the Tray
Settings ribbon, even if you inserted the objects with the Orient
Automatically option.
¾ The physical characteristics of each type of Model material you use can
affect the positioning of objects on the tray. Therefore, select materials
before running Automatic Placement.
