It looks like it should be possible to convert CAD models saved in IGES format and generate a VRML (Virtual Reality Modeling Language) file from the source. This can be probably done in several CAD / 3D modeling programs or even dedicated conversion or data translation software.
Convert IGES 3D exchange format to Virtual Reality Modeling Language 3D model.

Convert from igs file format
The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned igs to vrml. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
