Basic CAD model viewing and converting

Basic functionality is offered by CAD Data Exchange part of Open CASCADE Technology (OCCT).

The supported file codecs and knowledge are:

- BREP: native OCCT format for shape geometry, topology, and meeting construction.

- IGES (5.1 and 5.3): shape geometry, colours, top-level object names, file info.

- STEP (AP203 and AP214): shape geometry, meeting construction, colors, names, validation properties, file data.

Assembly structure of the mannequin may be navigated through the tree browser. The elements of the assembly can be hidden or shown as necessary to inspect the mannequin. The selected sub-assembly or part can be queried for its properties.

CAD model (whole or selected half or sub-assembly) can be exported to any of supported CAD or mesh codecs.

Viewing mesh data

Additional performance is viewing of mesh fashions with related data, implemented utilizing the mesh visualization element of OCCT.

Supported mesh codecs are:

- STL is de-facto standard in 3D printing.

- PLY has capability to retailer information related to mesh nodes and components. If you have in your utility a model represented by mesh, it might be saved easily to PLY format and viewed on a pill. Additional knowledge (RGB color or scalar) could be added to every polygon or node.

- OBJ is normal for 3D animation and supported by most 3D graphics applications.

- JT is ISO normal for efficient visualization of 3D CAD data.

- glTF is an open commonplace for 3D assets.

CAD Assistant lets you view the mesh in wireframe, shaded, and shrink view. If mesh accommodates related textures, colours, or scalar knowledge, it can be considered with components coloured based on the chosen property. For scalar portions interactive colour scale is shown, offering controls to manipulate the range of displayed quantities.

Common operations

CAD Assistant for Android is optimized for units with multi-touch display and provides intuitive manipulation of the 3D view by finger gestures.

Left toolbar provides buttons for fitting mannequin to window and selection of normal views. Settings submenu supplies entry to viewer and software options, file info, and message log.

Files can be opened from native storage (internal reminiscence or SD card). CAD Assistant integrates with Android so that functions supporting file associations will launch it for opening recordsdata of relevant sorts. For instance, you probably can open STEP file sent to you by mail by simple click on on attachment in mail client.

CAD models can be saved in STEP, IGES, or BREP format as CAD knowledge; CAD and mesh fashions may be saved in PLY, STL, or OBJ format as polygonal data. Save file dialog additionally permits saving present image of the mannequin to PNG format. If target listing Mail is selected, the mail client will be mechanically began with saved file as attachment.

Supported devices

CAD Assistant has been examined to work on a wide range of modern tablets and smartphones. Note however that it supports only panorama screen orientation and this might be inconvenient on telephones.

Application requires OpenGL ES 3.0 or OpenGL ES 2.0 with GL_OES_element_index_uint extension.

Limitations

Depending on a device, opening massive information could take time. Devices with low-range graphic processor might be sluggish on displaying large fashions. For massive scenes (millions of triangles), the system could kill the application with no warning because of GPU problems. In general, files less than 50 Mb can be considered safe for opening on all units.
