In this work we propose a scheme for analysis of the shape 3D model. We use Extended Reeb Graph to describe topological structure model which further enrich with extracted geometrical features. The nodes graph represent different components model, and analyze their separately. Shape characteristics such as taper/enlargement, average curvature, bending are revealed through tracing changes in cross sections each component. Finally together associated represents descriptor
