Key changes and new features:

• Support for new controllers (including P8III and eRTK25).
• Enhanced CAD functions: updated calculation algorithms, optimized real-scene staking, ability to set elevation for objects, project recovery after deletion.
• Expanded licensing options: updated activation code transfer mechanism for new devices.
• Optimized laser measurement: added auto-zoom and new tools.
• Improved file search and management: sorting by modification date, prefix saving, additional export options with cloud sharing.
• Fixed multiple bugs and improved overall performance.

Why it matters:

This update makes SurPad 4.2 even more reliable, versatile, and easy to use for surveying, construction, and precision farming.

3. Updated perimeter and area calculation algorithm.
4. Fixed issue in CAD where points and lines could not be selected during area clipping.
5. Optimized CAD real-scene staking.
6. File search now sorts results by last modified date.
7. Demo mode no longer requires registration.
8. Fixed crash when merging CAD objects if only one object exists.
9. Added export popup with cloud-sharing option when exporting CAD and coordinate library data.
10. Base map calibration data no longer shown in transformation parameters.
11. Fixed display bug for roads and bridges.
12. Fixed issue where auxiliary road lines were not displayed.
13. Added polygon area display switch in software settings (enabled by default).
