KOMPAS-3D© is a software system for three-dimensional design, which has become a standard for thousands of enterprises and hundreds of thousands of professionals. KOMPAS-3D is intended for creating three-dimensional associative models for individual parts and assembly units containing both original and standardized structural elements. A key feature of KOMPAS-3D is the use of its own mathematical core and parametric technologies developed by ASCON specialists. The system has a powerful functionality for the project management including thousand sub-assemblies, parts and standard products. It supports all the capabilities of three-dimensional solid-state modeling that have become a standard for CAD/CAM designs.
