What is a .3DM file?
3DM is the native model format of Rhino (Rhinoceros 3D). Created and opened by Rhino, built on the open OpenNURBS toolkit.
- Did you know
- Rhino’s 3DM format is based on the openly published OpenNURBS standard.
- Rhino itself was created by Robert McNeel & Associates, and version 1.0 shipped in October 1998 as an affordable NURBS modeller.
- More than 400 software teams exchange 3D models through the 3DM format, thanks to the freely licensed OpenNURBS toolkit.
- What Analyser reads
- Identify CAD files and read header metadata: AutoCAD DWG (DXF now opens as a 2D drawing preview - see Diagrams), SolidWorks (SLDPRT, SLDASM, plus .sldreg Settings Wizard backups - release year, settings groups and the saved registry keys - and SOLIDWORKS Visualize .svap appearances and .svpj projects, opened as the ZIP packages they are), Fusion 360 (F3D), Inventor (IPT, IAM), Rhino (3DM) and Grasshopper (GH, GHX), SketchUp (SKP), 3ds Max, Cinema 4D, Houdini, ZBrush, Maya, CATIA, Eagle, and KiCad.
- Depth of analysis
- .3DM is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .3DM file
- Drag a .3DM file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
