Abstract: A method of generating a three-dimensional (3D) structure model from a two-dimensional (2D) drawing file, which includes one or more illustrations of a structure, using a data processing device includes importing the 2D drawing file to the data processing device, converting the 2D drawing file into a raster graphics file, converting the raster graphics file into a vector graphics file, extracting one or more graphical projections representative of the structure from the vector graphics file, converting the one or more projections into a tagged data graphics file, forming a 3D structure model representative of the structure by connecting the plurality of cartesian points of the tagged data graphics file, and generating an electronic output file including the 3D structure model.
