You can specify ArcScene to display your data in any of the predefined geographic coordinate systems and projected coordinate systems supported by ArcGIS. Usually this setting would match at least one of your layer's source data coordinates.
- Right-click Scene layers in the table of contents and click Scene Properties.
- Click the Coordinate System tab.
- Double-click Predefined.
- Navigate through the folders until you find the coordinate system you want and click it.
- Click OK. All layers in the scene will now be displayed with that coordinate system.
