3D Files Viewer and Converter compared with Autodesk Viewer, MeshLab and Blender
3D文件查看器和转换器	Autodesk Viewer	MeshLab	Blender
主要目的： A web tool to visualise and explore 3D models in the browser, which also converts between formats. Its focus is inspection and quick conversion, not editing the geometry.	主要目的： A free online viewer for 2D and 3D designs, with a strong emphasis on drawings and CAD data from the Autodesk ecosystem.	主要目的： An open source system for processing 3D triangular meshes: editing, cleaning, healing, inspecting, rendering, texturing and converting. It targets scan data and models prepared for 3D printing.	主要目的： A 3D creation suite with a Python API and add-ons. It is a full production tool, far beyond viewing or conversion.
输入格式： 3dm, 3ds, 3mf, amf, bim, brep, dae, fbx, FCStd, gltf, glb, ifc, iges, step, stl, obj, off, ply and wrl. STEP, IGES, BREP and IFC are covered, which suits CAD and BIM files.	输入格式： Lists AutoCAD DWG and DXF, Revit RVT, Inventor IPT, STEP, SolidWorks and CATIA among many others. Strong coverage of proprietary CAD formats.	输入格式： Reads common mesh and point-cloud formats. Recent releases list glTF, GLB, NXS, NXZ, E57 and 3MF, and the full list is not on the home page.
Output formats and conversion: Exports 3dm, bim, gltf, glb, stl, obj, off and ply. Useful for converting a CAD exchange file into a mesh for printing or web display.	Output formats and conversion: The page describes a viewer, not a converter, and gives no export list.	Output formats and conversion: Can export meshes, with U3D export and direct upload to Sketchfab mentioned on the project page.
开放性和许可： The source code is open and published on GitHub under the MIT licence. It builds on libraries such as three.js, rhino3dm, web-ifc and occt-import-js, so you can embed or self-host it.	开放性和许可： Free to use, but a proprietary Autodesk service. It needs a WebGL browser (Chrome 56 or later, Firefox 51 or later, Edge 14 or later).	开放性和许可： Source under GPL 3.0. The MeshLab name is a trademark of CNR. Windows, macOS and Linux builds exist, and release 2025.07 appeared on 9 September 2025.	开放性和许可： Free and open source under the GNU GPL, usable for any purpose including commercial work.
Depth of mesh processing: Limited to viewing and format change. There is no mesh repair or analysis function listed.	Depth of mesh processing: View-oriented. Not a mesh repair tool.	Depth of mesh processing: Deep processing: hole filling, noise removal, simplification, remeshing, surface reconstruction, curvature evaluation and mesh boolean plugins.	Depth of mesh processing: Extensive, but it requires learning a complex interface and is not specialised for scan clean-up.
何时选择它： Choose it for a quick look at a STEP, IGES, STL or IFC file, or a one-off conversion, without installing software.	何时选择它： Choose it to open DWG, RVT or other proprietary design files for review.	何时选择它： Choose it to clean, repair or reduce scanned or printed meshes.	何时选择它： Choose it when the model needs real modification, rendering or animation.
