Kompas 3d LT - Version 7 System KOMPAS-3D is intended for creation of three-dimensional associative models of separate details and the assembly units containing both original, and standardised constructive units. Kompas-3D allows to realise classical process of three-dimensional parametrical designing from idea to an associative solid model, from model to the designer documentation. Key feature Kompas-3D is usage of an own mathematical kernel and the parametrical technologies developed by experts ask. The system possesses a powerful functional for operation over the projects including of some thousand, details and standard products. It supports all possibilities of the three-dimensional solid-state modelling which have become by the standard for a CAD of an average levelResources of import/export of models (Kompas-3D supports formats IGES, SAT, XT, STEP, VRML) provide functioning of the complexes containing various CAD/CAM/CAE systems.
