If it does then the DWGs are the reason.<BR /> Or delete all the PDFs and see if the speed improves. If it does then the DWGs are the reason.<BR /> If you delete all DWGs and PDFs (placed bitmap image files may also be a source of slowness) and the file is still slow, then probably the size of the model is the cause.
