各模块主要功能介绍：
DXF-Manager(Http://www.hexagon.de)
•    DXF-Manager for viewing DXF files and conversion to IGES, CNC-Code, HP-GL, HP-GL/2, Postscript, Pascal, C. Application Example: Generating CNC-Programs from CAD drawing.
DXFPLOT ()
•    Converter for DXF files to HP-GL and Postscript code. DXFPLOT can be used for output true scale drawings from HEXAGON mechanical engineering software.
FED1+ ()
•    Design and recalculation of cylindrical helical compression springs according to EN 13906-1
•    Output of results printout, extract, characteristic curve of the spring, Goodman chart, buckling field, temperature chart, quick output
•    Production drawing according to DIN/EN
•    Drawing of the spring viewed as an elevation and cross- section
•    Calculation of waste for special tolerances
•    FED1+ also includes a spring database, cost-calculation program and animation
FED5 ()
•    Design and recalculation of conical helical compression springs
•    Output of results printout, extract, progressive characteristic curve of the spring, Goodman chart, stress characteristic, graphs of the spring rate and spring energy
•    CAD drawing for any clamping lengths
•    Animation
•   
TOL1 ()
•    The TOL1 software helps you to reduce both the time spent calculating dimension chains and the potential sources of errors to a minimum. In future, you can calculate tolerances simply by generating a diagram of the elements and a table of all the relevant dimensions and tolerances - TOL1 takes care of the rest
WST1 ()
•    Technical data, strength values, alloy components, properties and utilization data for steels and NE metals are available in WST1. WST1 creates an extension-expansion diagram as well as fatigue stress diagrams for tension/pressure, bending and torsion.
ZAR1+ ()
•    The ZAR1 gear calculation program calculates the geometry and strength of externally and internally toothed straight spur and helical gears with involute toothing as well as rack-pinion gears in conformance with ISO Standard 6336 and DIN Standards 3960, 3961, 3967 and 3990. The program contains appropriate interfaces for linking it to CAD systems and databases.
