How can I view AutoCAD Architectural Desktop graphics in MicroStation?
In AutoCAD, use the PROXYGRAPHICS system variable to specify whether images of proxy objects are saved in the drawing. Set PROXYGRAPHICS to 1 to save the images in the drawing. These images are then displayed when you open the file in MicroStation. If PROXYGRAPHICS is set to 0, the images are not saved in the drawing, and bounding boxes will appear instead. If you are using AutoCAD Architectural Desktop (ADT), custom objects that normally have a height, width, and depth appear flat in MicroStation. To avoid this issue, change the named view to isometric before saving in ADT. The objects will then appear to have depth when they are displayed in MicroStation. If AutoCAD is equipped with Architectural Desktop object enablers, the objects will still appear flat in MicroStation. Currently, there is no workaround for this scenario.
