To position objects directly on the tray:
1. Selecttheobject.
2. FromtheObjectmenu,select
Lay On.
To ensure that objects are always positioned directly on the tray:
1. FromtheToolsmenu,selectOptions,anddisplaytheSettingstab.
Figure 5-21: Options dialog box, Settings tab
2. IntheAutomaticLayOn(Gravity)section,selectAlways.
Other Z-axis options (in the Automatic Lay On section):
• When under the tray—Thedisplayofobjectsthatarebelowthebuild
trayisautomaticallychangedsothattheobjectisattraylevel.
• Never—Thedisplayofobjectsthatareaboveorbelowthebuildtrayis
notchanged.
In practice, the Objet system prints all models on the build tray on a one-
millimeter bed of support material. The importance of positioning objects
directly on the build tray with Objet Studio is to correctly display the objects
on the screen.
