There are many stages involved in the preparation of the final 3D model. The 3D reconstruction is developed, validated, and delivered in stages. This incremental approach is designed to allow a constant evaluation of the accuracy of the source materials, highlighting discrepancies or inconsistencies as the reconstruction proceeds. Ultimately, the wider the range of historical evidence consulted the greater the potential for accuracy in the latest version of the structure.

The original ground plans and elevation drawings are scanned into Autocad and overdrawn to provide a base set of 2D drawings which are then used as a basis in the creation of the 3D reconstruction.

The modeling process began with an analysis of the 2D ground plans and elevations to determine the structures basic units of repetition. The main advantage of dividing up the structure into its units of repetition is that once these units are defined the file size of the model will not be increased, regardless of how many instances of that unit are implemented.

The most common modeling procedure used in the construction and development of the Huntsman model is the extrusion. The process begins with both the profile (cross section through the desired object) and the path (the shape of the object) being extracted from the ground plans and elevations. The profile is then extruded along the path to form the main structure of the object. These codes of construction are documented as a permanent record as the modeling proceeds.
