Abstract: On the base of the principle of matrix transformation of three-dimensional diagram,the scaling,rotation and translation for the element drawing data about internal force and displacement are carried out,and the diagram of internal force and displacement of space frame have been drawn with the transformed data by Matlab.The method and programme established in this paper can be applied to display of the analysis of space frame FEM in graphics mode.
