I have a problem with raster. I inserting a image (*.tif), i correlating with rubbersheet an i am exporting. When i am inserting, the image isn't in coordinates. Why?
 Please help me!! 

What kind of CAD software are you using? Georeferenced TIFFs are supported only in AutoCAD Map, Civil 3D or Raster Design - not in plain AutoCAD. In plain AutoCAD you can use our GeoRefImg utility - see:
