Eagle 转 KiCad 教程 — 2026 迁移指南

Yes. Autodesk officially announced EAGLE's discontinuation in 2023 and set the final sunset for June 7, 2026. New license sales stopped earlier, subscription renewals are ending, and cloud library services shut down on the sunset date. Existing installs continue to run offline indefinitely, but without updates or cloud sync. Autodesk directs the customer base toward Fusion Electronics (formerly Fusion 360 Electronics), which is a paid subscription bundled into Fusion 360 rather than a standalone EAGLE successor.

Yes — it has been built into KiCad since version 6 (released 2022) and matured significantly in KiCad 7 and 8. The importer reads .brd, .sch, and .lbr XML files directly and produces native .kicad_pcb and .kicad_sch output. Nets, layers, component placements, zones, and design rules transfer reliably. The parts that need manual attention are footprint library remapping (EAGLE package names don't match KiCad footprint library paths) and 3D models (EAGLE doesn't ship models, you'll need to find KiCad-compatible .step or .wrl files). For a typical hobbyist or small-team board, expect to spend an afternoon on remapping after a clean import.

KiCad 8 can import .lbr files through File > Import > Non-KiCad Library. The importer splits the EAGLE library into KiCad's separated structure — .kicad_sym for schematic symbols and .pretty folders for footprints. This is useful if you've maintained custom EAGLE libraries for years. For parts covered by KiCad's official libraries (which are extensive), it's usually faster to remap to the official names than to maintain converted custom libraries. For truly custom packages (odd mechanicals, proprietary modules), converting the .lbr keeps your existing work intact.

No — EAGLE's ULP (User Language Program) scripting is specific to EAGLE's C-like embedded interpreter and has no direct equivalent in KiCad. KiCad uses Python for scripting (via the pcbnew Python API). If you have ULP scripts for BOM generation, panelization, or custom DRC, you'll need to rewrite them in Python. The good news is KiCad's Python API is more powerful and has broader community support, so most ULP use cases have established Python equivalents or open-source plugins.

Yes — MakerSuite 3D opens both EAGLE .brd and KiCad .kicad_pcb files directly in the browser. Drop the original .brd in one tab and the converted .kicad_pcb in another, and visually compare layer by layer. Any silent regression from the importer (missing zones, flipped layers, rotated parts) shows up immediately in the 3D view. No KiCad install required for the verification step, which is useful if you're auditing converted boards on a machine that doesn't have CAD software installed.
