Reduce your calculation time in Siemens NX when working with huge patterns!

Handling large assemblies in Siemens NX can be nerve-wracking! Long calculation times hinder the daily workflow and slow down the process. Trainer and NX expert Simon was approached by a former customer with a problematic, huge pattern and of course he didn't give up until he found a solution.


If you are editing huge patterns that sometimes contain 500 or 5.000 features and still want to reduce the waiting time to a minimum, you have to understand exactly what affects the calculation time. Simon constantly performs benchmarks and workarounds and discovers new work processes and methods through his daily work as a Siemens NX trainer. That is why he has also found a solution for handling extremely large patterns and model histories. He is very excited to share his secrets with you now! If you find this helpful, you will certainly benefit from participating in one of our Siemens NX online training courses.
