The first row defines two base coordinates also known as the from-points with the following syntax. The information in a world file is comprised of two sets of points. The best CAD, BIM, and GIS workflows attempt to avoid the need for a world file by using geospatial coordinates within the CAD and BIM files themselves. The transformation information is only valid with the matching spatial reference file (PRJ) for which it was created. The points are used to calculate two vectors that define the offset, scale, and rotation of coordinates within the assigned spatial reference. A world file (WLD3) is a text file containing four points that describe a coordinate transformation.
