We list trade-offs explicitly. Browser-based + privacy-first means some features that need a server (cloud sync, named-account workflows) won't ship here.
LINE, CIRCLE, ARC, LWPOLYLINE, POLYLINE, SPLINE, and ELLIPSE in v0.1. SPLINE renders via fit or control points (straight-line approximation). TEXT, MTEXT, BLOCK insertion, and HATCH are skipped — the status footer reports how many entities were skipped per type.
Both — dxf-parser auto-detects.
TEXT and MTEXT (no font rendering), HATCH (no fill patterns), BLOCK insertion expansion (block reference not expanded), 3DFACE / MESH (3D entities, rare in 2D DXF). On the roadmap.
No. dxf-parser is a pure-JS library and runs entirely on your device.
DWG has no permissive parser — every open-source DWG library is GPL-licensed. Convert to DXF in AutoCAD / LibreCAD / QCAD first.
