Frequently Asked Questions
Can I keep my old templates?
Drawing templates and standards carry forward; verify them once after migrating.
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.
Will it open files from other CAD systems?
STEP, IGES and Parasolid imports are standard; native formats depend on the included translators.

Tips from Real Projects
For a machine rebuild, the Siemens NX (Ver2312) model became the contract: measurements, clearances, and the cut list all came from one file. What made the iterations cheap: parametric templates, one shared coordinate frame agreed with the robot team, and every variant kept rather than overwritten. Export with named coordinate frames when the file goes to offline programming; unnamed frames cost the robot team an afternoon of guessing.
