The Group of programs is able to solve different problems from structural analysis to interchange data through the data base. SOFiSTiK consists of a large number of modules which communicate with each other either trough standard text files or through graphical interfaces. CADINP is a powerful command language. It allows full operation of the possibilities of certain modules in the analysis. Experienced programmers use flexible CADINP macros to simplify the data input, especially when entering complex systems.

8 SOFiPLUS is a graphic preprocessor which is used to create the structure. With its help, AutoCAD drawings and DXF files are converted into structural elements. The program is based on AutoCAD. The contours of the structure is drawn with the AutoCAD commands. A great number of functions easily permit to convert the basic AutoCAD entities in structural elements and loads. As a preprocessor, SOFiPLUS creates the input file, which is later used by the adequate SOFiSTiK modules for structural analysis. Therefore SOFiPLUS is the right product for any user, who wants to use the functionality of the SOFiSTiK analysis programs in conjunction with AutoCAD.

9 Pic. 1 SOFiSTiK Organization chart WORKING DIRECTORY For practical purposes it is recommended to save any data from a project in one working directory. It is eligible to create a directory with the same name as the project name. The user should create such a folder before drawing the first drawing. This directory will then contain the necessary drawings and data for the analysis of the structure. 1 8 DRAWING NAME The drawing name should contain the necessary information to identify the drawing without having to view it.

10 The project number, position or index may be used as recognized attributes from the drawing file name. Example: project number A name of structure to be analyzed a index a .dwg file extension (AutoCAD file) LAYERS Objects created with SOFiSTiK have properties: layer, color and line type. Layers are construction plans on which objects are systematically grouped with different drawing information. Some layers are created during the work with SOFiPLUS . For example the program SOFiPLUS puts any nodes on the layer X__KNOT_database name.
