DeXeF

View DXF files. Free and open source.

DeXeF views DXF files on Apple devices. Open a drawing and pan, zoom, and read off coordinates against a reference grid, with every layer just a toggle away. On macOS, DeXeF also provides Quick Look previews and Finder thumbnails, so you can peek at a DXF file without opening the app.

There are many DXF viewers on the App Store, but all of them are terrible and cost too much. This one is free, low on mystery meat, and hopefully broadly functional.
