ForTen 3000 is a system for Tensile Structure design, structural non-linear Analysis and pattern making. Developed since 1991 counts more than 150 users worldwide. Based on a mixed Force Density & stiffness method technically any shape that satisfies tensile structure rules can be designed. Membrane stresses,reaction forces and steel efforts can be visualized and printed. Non-Linear Membrane,Cable & Truss elements plus linear beam elements are supported. Material database of common used pvc and fiber glass coated fabric are available with the ability to add user defined materials. Cross section databse of 4000 steel profiles ready to use. Static non linear analysis and mixed Non-Linear/Linear with any number of user defined load cases. Wind,Snow and any load can be applied on the model even user the powerful scripting language to defined wind load behaviour. With the new DSS kernel analysis is FAST from 500 to 1000 faster than ForTen 2000. Membrane stress plots, reaction forces,supporting structure forces and deformed shapes can be plotted and animated on screen. Final report generator for printing professional reports of all data. Patterning complex double curved shapes has never been so easy. Section cuts, geodesic curves and user defined curves can be used to cut and create seam curves over the surface.3D patches are flattened with control of exact edge match techology to assure perfect assembly of final model.Production pattern module to apply welding offsets, markers for assembly purposes and biaxial compensation. Automatic Layout with 3d assembly, pattern 2d assembly and single pattern with point table, edge lengths and system points to avoid any possible mistake while assembling. Import/Export to DWG and DXF file of any geometric entity,from model to patterns to cross sections. Import native Rhinoceros 3dm files with conversion of nurbs surfaces to Tenso groups.
