How to reduce the important information losing about 3D models in process of feature extracting is still a problem in content-based 3D models retrieval. A novel method for 3D models retrieval was proposed. The longitude and latitude of spherical surface were used in sampling process. After sampling from 3D models surface some sampled points were obtained. In each facets which contains sampled point of 3D model surface, a function was defined with the square and the orientation of the facet. Then the 3D Radon transform was used to a set of the functions. Experimental result show the proposed method is received a better performance.
