Avoid Expensive Collisions: 3D_Evolution Software with New Tool for Collision Checking

The software accurately detects 3D collisions and helps avoid high costs from errors during the commissioning of machines and plants.

The analysis software 3D_Evolution detects collisions between components with precision and helps prevent costly changes and delays during the commissioning of machines and plants. The latest version of the integrated DMU Inspector tool features an optimized web interface, enabling the fast analysis of large 3D CAD data and efficient collaboration between development teams.

The new software version of the 3D_Evolution DMU Inspector for collision detection is now available. The software was specifically developed for the needs of machine and plant engineering. With the new tool, it is possible to ensure before assembly that no collisions, i.e., interferences, occur between components. This reliably avoids expensive changes and delays during commissioning. Particularly during the assembly of complex machines and plants abroad, faulty parts and the resulting changes represent a significant cost factor, which can be effectively avoided using the DMU Inspector.

Precise Collision Checking

For machine and plant engineering, distinguishing between contact and actual collision is crucial to a meaningful collision analysis. With inaccurate, tessellated models, thousands of non-existent collisions are often displayed, making a collision analysis impractical. To address this challenge, the DMU Inspector was developed as the world’s first tool to perform collision analysis on exact CAD models rather than on a triangulated approximation. This allows for a precise distinction between contact and interference, ensuring that only real collisions are displayed.

High Performance and User-Friendliness

For collision analysis of large datasets, the multi-processor computation in the DMU Inspector software offers significant performance advantages. The software, which can be installed on a web server, allows for calculations across as many processors as needed. This enhances the documentation of results and collaboration between development teams, as the data is centrally hosted on a server. Designers log into a project, review the recorded collisions in a web browser, and perform a detailed analysis in the integrated 3D viewer. Unlike static reports, such as in PDF format, project progress is dynamically documented in the DMU Inspector. When assemblies are recalculated, only the changed and corrected components, as well as directly adjacent components, are rechecked for collisions.

The tool stands out for its extremely fast display of large volumes, ease of use, and clarity. Collisions between components or subassemblies are clearly displayed in list format and through the 3D viewer. Smart filter functions aid in cross-team collaboration.

The calculations are compatible with all common CAD formats, including Catia, Nx, Creo, STEP, JT, PLMXML, Solidworks, and Inventor assemblies. Due to its straightforward setup and numerous interface formats, the software is flexible and ready to use in any PLM environment without requiring complex integration.
