Abstract: Based on secondary development of ArcGIS Engine，a cutting algorithm suitable for grid cells of six-sided block was proposed on the foundation of zone information of models in order to achieve the function of cloud picture view.The algorithm can achieve cutting model along three axis directions and quickly generate color cloud picture.According to the method，the stress condition of three axis direction can be quickly showed by cutting numerical models based on secondary development of ArcGIS Engine.

Key words: ArcGIS Engine, Cutting algorithm, Cloud picture
