Sketchup Pro Trial Version

Unlike some software where you can change your system date, Trimble’s servers track your hardware ID and IP address. You cannot trick the system by uninstalling and reinstalling. The trial is "one machine, one email, once per major version."

The unspoken asterisk: files created or edited in the trial version retain Pro-level features. Once the trial ends, opening those files in the free SketchUp (Web or Make) can cause loss of those Pro elements (e.g., dynamic components, advanced section planes, LayOut references). So the "trial" leaves behind a subtle lock-in: either subscribe or lose fidelity. Sketchup Pro Trial Version
