I m using Autocad Map 3D 2009 version and want to know if in the latest version is there a provision of georeferencing unwarped images in Autocad Environment.

Hi there I've recently been tasked with importing some geo referenced tiff images. As far as I could find there is no built in system for what your trying to do, However you can utilise the insert X-ref command to alter the scale and point in such a way that it will effectively place and scale the image/file correctly i.e. just like it was an automated/built in geo-referance attach command.
Ive attached a pdf of the method for doing this. I hope it helps in some way with what your trying to do.

Map 3D by itself won't generate a world file, though Raster Design will. However, the world file format is simple - it's just 6 lines. WIth a little pixel measuring and careful determnation of the XY coordinates of the upper left pixel, you can piece one together: http://en.wikipedia.org/wiki/World_file
As for the initial placement, download the Raster Object enabler for 2009 (autodesk.com/oe), then use the MAPIINSERT command to ballpark the insertion point.
Hello Santosh Udyavar,
I was not aware the the Rubber Sheet command in Map 3D worked on Raster Images. I thought it was more like a multiple point Align. I know that in Raster Design the Rubber Sheet command works specifically on images and will adjust the image pixel by pixel to give the best fit.
As far as the World File goes. As mentioned by others, it's not too difficult to create one manually. So if you get the results you want from the Mao 3D Rubber Sheet command and you don't have too many images to do. That might be the way to go.
OK. I've done a little research. It looks like the Rubber Sheet command in Map 3D will move and scale an image. But it doesn't truly rubber sheet the image. If you turn the imate in to a Block, it will also distort the X,Y aspect ratio.
