Views of the work <Back
There are 6 standard views (top, left, bottom, and so on) which may be selected from the toolbar or the View menu under Orientation.
Tools (the toolbar), Help (this window) and Object Tree are windows that can be enabled from here. Object Tree is a tree-list view of all the objects.
Rendered View creates a triangle mesh from all the volumes and lights it using OpenGL lighting.
Perspective and Orthographic views can be selected.
