Raster design rubber sheet.
See my previous post on raster design for more details about fixing image skew.
The autocad raster design toolset helps you convert raster images into dwg objects with its powerful vectorization tools.
I m assuming you are using raster design.
Go back to my second post to see how the rubber sheet can help you with this.
The anchors at the four comers really help.
Rubbersheeting is commonly used after a transformation to further refine the accuracy of the features to an existing layer or raster dataset.

You must select at least three pairs of source points and destination points.
The rubbersheet dialog box disappears and autocad raster design toolset prompts you to select the first source point.
The convex hull of destination points is displayed in red while the convex hull of source points is shown in blue.

Then choose add points and start clicking on the drawing.
You may notice some of the drawing was fixed but there are other places in the drawing that are not orthogonal.
You have been detected as being from.
Conflation applications use rubbersheeting to align layers in preparation for transferring attributes.
The preview tool allows you to see the extents of the transformed image before you actually apply the changes.
You can select points on specific raster entities by using raster snaps.
Autocad raster design toolset does not limit the number of control points you can use.
Where applicable you can see country specific product information offers and pricing.
Below is a picture of my rubber stamp points for this.
When i rubbersheet i always anchor the two known points that i matched the image too and then i anchor all 4 corners of the image.
After the anchors are set i will define the stretch points.
Rubber sheet command step 2 the first point you click will be where the image file is off.
