When supplying finite element model (FEM) plate bending programs with a full‐range interactive graphical input‐output system several graphical problems have to be solved. How can vectors and matrices be found to describe the topology of a figure defined by drawing lines on the screen? How can the information arrays of finite elements be built up when the mesh is given as a set of lines drawn on a screen? What specialities characterise the visualisation processes, in the case of level line figures, pictures according to three‐dimensional visibility, or unfolded cross‐sections? Solutions to some of the most interesting problems will be introduced here.
