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.

A method of generating a three-dimensional (3D) structure model from a two-dimensional (2D) drawing file using a data processing device, comprising:

(a) importing the 2D drawing file to the data processing device, wherein the 2D drawing file includes one or more illustrations of a structure;
(b) converting the 2D drawing file into a raster graphics file;
(c) converting the raster graphics file into a vector graphics file;
(d) extracting one or more graphical projections representative of the structure from the vector graphics file;
(e) converting the one or more projections into a tagged data graphics file, wherein the tagged data graphics file includes a plurality of cartesian points;
(f) forming a 3D structure model representative of the structure by connecting the plurality of cartesian points;
and
(g) generating an electronic output file including the 3D structure model;
wherein converting the 2D drawing file into the 3D model includes:
(i) performing dilation to emphasize features of the structure and to join together detached parts of the structure within the 2D drawing file;
and
(ii) performing contouring to append continuous lines of the structure along identified boundaries.

(d) extracting one or more graphical projections representative of the structure from the vector graphics file;
(e) converting the one or more projections into a tagged data graphics file, wherein the tagged data graphics file includes a plurality of cartesian points;
(f) forming a 3D structure model representative of the structure by connecting the plurality of cartesian points;
and
(h) generating an electronic output file including the 3D structure model,
wherein the electronic output file includes an OBJ file which contains the 3D structure model;
wherein converting the 2D drawing file into the 3D model includes:
(i) performing dilation to emphasize features of the structure and to join together detached parts of the structure within the 2D drawing file;
