Convert PLY to DXF
Convert PLY files to DXF in your browser. Free, no upload, no sign-up.
Convert PLY files to DXF directly in your browser. The converter parses the PLY mesh, rebuilds it in memory and writes it out as DXF, triangle for triangle. DXF records shape and nothing else, so the colors in the PLY file do not come across. The two describe the same kind of mesh, so what changes is the container: PLY is either text or binary, DXF is a text file you can open in an editor. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. DXF is what 2D CAD software, laser cutters and CNC routers read, and AutoCAD imports a mesh from it with no plugin.
How to convert PLY to DXF
- 1Drop your PLY file
Drag a .ply file onto the box above or click to choose one.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the DXF
Adjust the export options if needed and click download. The mesh is written as 3DFACE triangles in millimeters. Colors, textures and materials are dropped, and the result is a faceted mesh rather than editable CAD curves.
What are PLY files?
PLY was designed at Stanford to store 3D scanner output. It supports per-vertex colors and arbitrary custom properties, in either ASCII or binary encoding, which is why scanning and photogrammetry software prefers it over STL.
Commonly used by: 3D scanners, photogrammetry (Meshroom, RealityCapture), MeshLab, research tools
What are DXF files?
DXF is the open interchange format Autodesk published for AutoCAD in 1982. Most DXF files are 2D drawings: lines, arcs, polylines and text on layers. Some also carry 3D geometry as 3DFACE entities. It is what 2D CAD, laser cutters and CNC routers exchange.
Commonly used by: AutoCAD, LibreCAD, QCAD, Laser cutters, CNC routers, Fusion 360 sketches
