In this exercise you use Match to correlate an aerial photograph to a vector drawing.
Match applies linear correlation, adjusting insertion point, scale, and rotation as necessary, to align a raster image with known points in a vector drawing or with another image.
To match an image to a drawing, you select two source points on the image and two corresponding destination points in the drawing. AutoCAD Raster Design toolset uses these points as a reference to reposition the image relative to the drawing.

Match
.
- For the first source point, select the upper right viewport, then select the source point on the image.
- For the first destination point, select the upper left viewport, then select the intersection of the stone wall and the parcel boundary, at the center of the X.
Match the second point
- For the second source point, select the lower right viewport, then select the source point on the image, at the lower right corner of the barn.
- For the second destination point, select the lower left viewport, then select the center of the X.
When you click the second destination point, the image immediately snaps into alignment with the drawing.
