Integration of mechanical calculation programs in CAD systems

In connection with the measures for rationalisation it gets more and more important to integrate the processes of design and process planning in CAD-systems. So it is secured that the shape describing data which are generated with the aid of CAD-systems and are stored in the computer can be used by other processes. Among the processes that have to be integrated, do count among others, also mechanical calculation programs, for they need beside problem oriented data geometric input data as well. The principle proceeding when integrating calculation programs is discussed by the example of the 3D-CAD-system COMPAC and a calculation program for shafts and the automatic Finite-Element mesh generator COMFEM.
