★★★★★
GorkyCAD cut our typical cottage design time from 3 days to 4 hours. The auto-recalculation is pure magic.
Alex P., Electrical Design Engineer, Moscow
★★★★★
I used to juggle nanoCAD and Excel. Now everything is in one window: plan, schematic, and spec synced.
Dmitry K., Lead Project Engineer, Yekaterinburg
★★★★★
Built-in IEC standards mean I don't have to double-check every detail. AI catches errors I would have missed.
