Anthropomorphic models are widely used in computer simulations to calculate conversion factors for external and internal dosimetry. However, their
construction is difficult and delayed due to the CT images segmentation. In last years, CAD (Computer-Aided Design) programs were used to develop
new anthropomorphic models in NURBS, MESH and POLYGON surfaces. However, most of the current simulation codes don’t allow entering the
objects in CAD format, making it necessary to convert the CAD model into a voxels matrix. In this paper is presented a methodology that allowed to
exporting objects created in CAD programs into the form of MCNP input files quickly and reliable. With the process were obtained very good results.
The shape and size of the voxel model match up very well with the original mesh. The working time required for the setup the 3D animation, export
the model and create MCNP input file was lower than an hour using a common PC.
