About the 3D Document

You can also access 3D Documents through the Go command of the Mini-Navigator Toolbar, or from the Window > Navigate > 3D Documents menu, or from the Window menu.
However, like other model views, the 3D Document has its own 3D Document Settings dialog box, where you can set parameters that are specific to the 3D Document: these include fill/pen display of element surfaces (including cut composite elements) and contours, transparency, 3D hatching, shading, shadow and sun effects.
Note: The display of composite elements in the 3D Document window also depends on the Partial Structure Display settings.
