Open your 3D model files quickly. This is an online viewer, so you need to be connected to the Internet to be able to view your STL files for free. This 3D viewer works for both STL and OBJ file formats.
3D Viewer Install From AppIGES (5.1 and 5.3) — vendor-neutral format for data exchange among CAD systems (ASCII format). Supported data: shape geometry, assembly structure, colors, names, validation properties, file information, dimensions and tolerances (semantic and tessellated PMI). STEP (AP203, AP214 and AP242) — ISO 10303 standard for product data representation and exchange among CAD systems (ASCII format). The program supports the following file formats: iOS: install from App Store or get IPA archive.Basic functionality is provided by XDE component of Open CASCADE Technology (OCCT).XBF — BinXCAF, which is a binary persistence format for universal XCAF document structure used by OCCT. Supported data: shape geometry (triangulation), assembly structure, PBR metallic-roughness materials with texture maps, names. glTF — API-neutral runtime asset delivery format (ASCII or binary), commonly supported by modeling systems and game engines.VRML or WRL — ISO 14772 virtual reality modeling language (ASCII format). Supported data: triangulation and quads, plain list of named groups, common materials with texture maps. OBJ Wavefront — format for 3D assets exchange commonly supported by modeling systems and game engines (ASCII format). Supported data: shape geometry and assembly structure (defined by nested compounds, without names). BREP — ASCII persistence of shape Boundary representation used by OCCT with open specification.Viewing mesh data with mapped quantitiesViewing mesh models with associated data is an additional functionality included in CAD Assistant.Mesh can be read from files in PLY format. The selected sub-assembly or part can be queried for its properties including names, product information as well as geometrical ones (area, volume, and centroid).Properties of a selected part in CAD AssistantThis CAD file reader can save models into a neutral (STEP, IGES, glTF, OBJ, PLY, STL) or OCCT internal (BRep, XBF) format. Assembly components can be hidden or shown as necessary to inspect the model. Mesh Shrinked (shaded mesh with gaps between triangles) Mesh Edges (mesh wireframe on top of shading) For scalar quantities a color scale is shown, providing controls to narrow the range of displayed colors if necessary to inspect the data with more details.Results of strength analysis of bulk carrier ship (courtesy RINA S.p.A.)CAD Assistant supports various Display Modes for analyzing mesh structure, material properties and mapping various quantities, including: If a mesh contains associated color or scalar data, it can be viewed with elements colored according to the selected quantity. Additional data (RGB color or scalar) can be added to each polygon or node.CAD Assistant allows you to view any mesh in wireframe, shaded, and shrink modes. If you have a model represented by mesh in your application, it can be saved easily to PLY format and viewed on a tablet. Excel for mac 2008 sort by columnParasolid import – X_T (text) and X_B (binary) files.Data import provided by commercial Open Cascade components is available in CAD Assistant with one restriction — disallowed model export/conversion. ACIS import – SAT (ACIS Text) and SAB (ACIS Binary) files. JT import – ISO 14306 JT binary visualization format. IFC import – ISO 16739 IFC2x3 and IFC4 files (ASCII format). Shaded with Edges (shaded with topology edges)Texture maps available within the document can be enabled one-by-one for material diagnostics.Shrunk mesh presentation in CAD Assistant Extended CAD model importMore 3D files formats are provided by Open Cascade commercial XDE components: Clipping Planes functionality allows accessing inner model details.Material Editor allows easily modifying properties of existing materials (from Bill of Materials within imported document), as well as defining new ones and assigning them to selected objects. Settings submenu provides access to the viewer and application options, file information, and the message log. Fit model/selection to the window by double tapView Cube and context menu provide actions for fitting a model to the window and a choice of standard views. In general, files less than 50 MB can be considered safe for opening on most devices. For scenes consisting of several millions of triangles, the system may kill the application with no warning due to GPU problems. Devices with low-range graphic processors could be slow when a large model is displayed in the viewer. However, we warn smartphone users that the application is optimized for landscape screen orientation and might be inconvenient on phones in portrait orientation.Depending on a device, opening large files may take time. iOS platform (iPad, iPhone), supporting version 8 and aboveIt has been tested to work on a range of modern middle-level tablets and smartphones.
