Instanced objects are AutoCAD, Revit or Architectural Desktop objects or blocks that you can drag and drop into Autodesk VIZ.
Modifiers and materials that are applied and assigned to an instanced object propagate throughout all instances of the object. For example, if all the doors in a scene have glass panes and you change the glass material of one door, all the doors of the same style will adopt that material. Propagation of materials can be controlled by toggling Propagate Materials To Instances.
Once you link a model to Autodesk VIZ, instanced objects can be transformed (moved, rotated, or scaled). If you don't like the way an object is transformed, you can use the Undo command or Reset Transform button on the Modify panel.
