In an embodiment, a drawing file and an interface application are activated. Geometry data is extracted from the drawing file with the interface application. In another embodiment, contents of a geometry file can be automatically read into a drawing application to create a drawing file. Contents of the geometry data file may be revised before being read. In another embodiment, a finite element model can be generated. A control file for an item to be modeled is selected. Contents of the selected control file and part geometry data files identified in the selected control file are read. A finite element model for each part is generated simultaneously from all of the part geometry data files. When more than one part geometry data files are identified in the control file, all of the finite element models of the parts can be integrated into a finite element model of a product.
