2026x Hot Fix 2
CATIA Magic / No Magic Modeling Tools
Released on: March 20, 2026
2026x Hot Fix 2 is now available for CATIA Magic and No Magic portfolios. It includes a number of improvements, bug fixes, and vulnerability fixes in our modeling tools and server products.
Hot Fix version compatibility
The version and Hot Fix number of a modeling tool and its plugins must be the same. After installing the Hot Fix version of a modeling tool, select the same Hot Fix version when downloading its plugins. The modeling tool will not work correctly if you install plugins of a different version and/or Hot Fix number.
