Frequently Asked Questions
Will it open files from other CAD systems?
STEP, IGES and Parasolid imports are standard; native formats depend on the included translators.
What hardware gives the best experience?
A current 6–8 core CPU, 32 GB RAM and a workstation GPU handle most assemblies smoothly.
Is there a learning path?
Built-in tutorials cover the core workflows in a few hours each.
Can I keep my old templates?
Drawing templates and standards carry forward; verify them once after migrating.

Tips from Real Projects
A robot-cell fixture went through three design iterations in one week in CATIA P3 V5 R2021, and the third one was the first the welder could actually reach. The discipline that helped: modeling to the manufacturing method — bends, weld prep, and machining stock included — so the drawing followed the model instead of fighting it. Export with named coordinate frames when the file goes to offline programming; unnamed frames cost the robot team an afternoon of guessing.
