# CADProps > CADProps is a fast, free online CAD viewer for parts and assemblies, with STEP measurement and support for 55+ CAD file formats and extensions. No desktop CAD installation is required. A feature-rich online CAD workspace brings viewing, measurement, model properties, assembly inspection, comparison, conversion and sharing together in one place. CADProps helps mechanical engineers, CNC machinists and manufacturing suppliers inspect STEP/STP and other supported CAD files online. Use it to check part dimensions, review loaded assembly components and estimate material weight before CNC quotations and supplier handoffs. Key capabilities include: - Open STEP/STP files and inspect 3D geometry in a browser. - Measure X/Y/Z dimensions, distances and supported geometric features; switch between metric and imperial display units. - Calculate volume and surface area, and estimate weight using your chosen material density. - Inspect supported assemblies and individual bodies with component selection, visibility controls, section views and exploded views. - Compare CAD models visually; STEP pairs also support solid-difference analysis. - Export model properties as CSV and download validated format conversions. - Share completed 3D models by link, with optional password protection and browser access for recipients. Supported formats include STEP/STP, IGES/IGS, STL, OBJ, 3MF, static GLB/glTF and supported DWG/DXF drawings. Native CAD files are read in-house, with results that depend on the format: Parasolid X_T/X_B and ACIS SAT/SAB are read as B-Rep; exact STEP export needs every face to be reconstructed. SolidWorks SLDPRT, Autodesk Inventor IPT and CATIA V5 CATPart give exact geometry and exact STEP export when the part's B-Rep is read completely; otherwise they show the display triangles saved in the file. SolidWorks SLDASM, Inventor IAM, Siemens NX PRT, JT, Rhino 3DM and Solid Edge PAR/PSM are shown from saved or tessellated display geometry with approximate properties, and their STEP export contains triangles rather than exact surfaces. CATIA CATProduct shows only the thumbnail saved in the file; Solid Edge ASM shows supported saved assembly scenes as an approximate preview, otherwise its thumbnail. Creo PRT/ASM, including numbered saves, are recognized and can show only their saved thumbnail: no Creo 3D geometry, measurement or STEP export. DWF/DWFx show read-only supported XPS/W2D vector pages or saved thumbnails, with W3D/HSF thumbnail-only, no CAD measurement/editing and displayed-page SVG export. Assembly references and multi-file resources can be packaged in ZIP. 3DXML XML tessellations, PLY triangle surfaces and static supported VRML97 WRL/VRML/WRZ scenes are approximate meshes with unverified units assumed millimetres. AMF flat triangle volumes apply declared units, defaulting to millimetres, normalized to millimetres. These four inputs support STL, OBJ, GLB, glTF, 3MF and tessellated mesh STEP export, not exact B-Rep. 3DXML binary representations, PLY point clouds, external VRML Inline content and AMF curved triangles are unsupported; incomplete scenes have no whole-model physical properties. SLDDRW, IDW, DFT, CATDrawing and Creo DRW/DRW.N show only saved preview images with unknown units: no drawing-view, dimension or title-block reading, 3D geometry, rotation, measurement, exact properties or model conversion. STEP STE/P21 and gzip STPZ, Parasolid XMT_TXT/XMT_BIN and IGES IGE are aliases with the same underlying capabilities. ZIP or RAR4/RAR5 can package local assembly references, with normal limits of 50 entries and 200 MiB expanded. Encrypted and multi-volume RAR, unsafe paths and links are rejected; 7z is unsupported. Archive packaging does not enable unsupported geometry. CADProps processes uploaded files on the server. Viewing and measuring are free and do not require an account; converting, saving files across devices and creating share links require sign-in. Share recipients do not need an account. Guest uploads are automatically deleted about one hour after upload, or can be deleted earlier. Signed-in uploads are saved to private My files storage (200 MB, up to 100 files) and automatically deleted after 90 days without use by the owner. Opening a saved file or downloading its original starts a new 90-day period; viewing the file list or opening a share link does not. Owners can delete saved files anytime; their results are removed and their share links stop working too. Files and results that cannot be saved remain temporary. The default upload limit is 95 MiB per file. Data security: all traffic uses HTTPS with TLS 1.2 or 1.3 and HSTS. Automatic expiry and manual deletion remove the online originals, previews and calculated results. Deleting a saved file also disables its share links. Original CAD files are not sent to external CAD processing services and are not used to train AI models. CAD viewing and inspection: open supported parts and assemblies quickly in one browser workspace. Inspect components, use section and exploded views, and check dimensions and available properties. Exact geometry properties and approximate mesh results are identified separately; availability depends on the file. Files are processed on CADProps servers. Limits: 95 MiB per file, 200 MiB expanded ZIP, 10 files per upload, 2,000 bodies per assembly, 1,000,000 display triangles per preview and 120 seconds of processing per preview. In a 2026-10-06 production sample of 60 previews, the median time to a finished preview was 3.4 seconds and 91.7% finished within 10 seconds. A 50 MB public STEP assembly took about 35 seconds. Best fit: machining and quoting staff, purchasing and supply-chain engineers, and incoming-inspection staff who need dimensions, volume, estimated weight, assembly contents or revision comparison without installing CAD software, including on a phone. Full specifications: https://www.cadprops.com/specifications/ Trust and evidence: CADProps guides are written and reviewed by the CADProps team, cite relevant sources, and are checked on public CAD files with reproducible examples. Editorial policy: https://www.cadprops.com/editorial-policy/ Coverage: 3Druck.com (2026-09-27, German), 3D Printing Journal (Western Report #10, 2026-10-02), Stampare in 3D (2026-09-27, Italian) and 4Additive (2026-09-28) have written about CADProps; the Awesome CNC list on GitHub includes it in its CAD section. Details: https://www.cadprops.com/press/ Fast CAD viewing: https://www.cadprops.com/fast-cad-viewer/ shows real public parts and assemblies, screenshots and measured waiting times. In a single sequential production check on 2026-10-09, two public STEP parts showed their first visible 3D frame in 2.9 and 3.2 seconds after upload; an 11.38 MB Cabin ZIP showed visible 3D in about 20 seconds, with further loading to a final displayed result of 227,186 triangles across four components, marked incomplete. These observations are not a guarantee for every file. Free test parts: https://github.com/cadprobs-a11y/cadprops-step-models has 30 parts in STEP, STL and IGES with envelopes and source records (CC BY 3.0 and CC0). DWG and DXF tools provide 2D drawing preview, layer filtering, measurement and export. Sharing creates a fixed snapshot of one completed 3D model for 7 or 30 days, with an optional password. Recipients can view, section, inspect properties and measure without signing in, subject to format limitations. The original CAD file is not offered for download. Manage shares from the signed-in account. Deleting a saved source file revokes its share links. Links below point to Markdown copies of public pages. Each copy names its HTML page. Localized pages and long-tail guides are listed under Optional. ## Product and policies - [Multi-Format CAD Viewer & Online Measurement Tools](https://www.cadprops.com/index.md): Quickly view and measure SolidWorks, NX, Inventor, CATIA, Parasolid X_T, SAT, JT solids, STEP, IGES and mesh formats online.
