This report describes an approach for creating a human CAD Computer-Aided Design model as a foundation for a finite element thermoregulation model FETM. The 3D human CAD model was developed in SolidWorks Concord, MA. The external dimensions of the model were estimated from thirty 36 anthropometric dimensions and the dimensions of internal tissue layers were estimated from 9 measurements of Dual-energy X-ray absorptiometry DEXA. The CAD model assembly is made up of fourteen sub-assemblies that include the head and torso as well as right and left components of the upper arm, lower arm, hand, upper leg, lower leg, and foot. Each sub-assembly is comprised of two to four tissue layers. Sizes of the CAD model are linked to anthropometric measurements and DEXA scan data via a Microsoft Excel spreadsheet and macros in SolidWorks. Thus an individualized CAD model will be created automatically after the anthropometric and DEXA data of a specific person are input in the Excel sheet.
