The calibration of the coordinates allows the user to correct the inaccurate coordinates by means of calibration points.
Start the Print2CAD analysis and look at the separated PDF images.
The calibration points can be defined in the paths or in the raster images. Find in the separated images the ends of the polylines. These can be defined as calibration points. The points of the raster traces after the vectorization can serve as calibration points. You can also define the calibration points freely in the drawing, without a connection to an existing point.
Try to find the information about the nominal coordinates of the points in the analysis images.
