Detailed informations to 3D FEM-System for general structures

Programme system with Windows®-oriented working environment, graphically interactive input, analysis and evaluation for beam, slab, wall and general shell structures. The limitations of the introductory version are neutralised by this programme enhancement, so that the application supports the following input, calculation and design options:

Usage of templates for user-defined programme configuration
Filter functions for the specific processing of structure types, e.g. grid, plane frame, plates etc.
Interfaces for ZEICON®, 3D-DXF, DIAMO as well as different point and axial data formats, e.g. DA040
Parameterised standard profiles for all applications
Profile database for standard profiles in steel construction
Material database for concrete, wood, steel and soil materials that comply with the standards, as well as option to input self-defined material characteristics
Working environment for 3D constructions with straights, clothoids, circular arcs, polygons and splines
Processing of the structure geometry in arbitrary construction planes
Measuring functions, text functions and chain dimensioning
Names of positions and objects, object descriptions and texts
