Basic CAD model viewing and changing

Basic performance is provided by CAD Data Exchange component of Open CASCADE Technology (OCCT).

The supported file formats and information are:

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

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

- STEP (AP203 and AP214): shape geometry, assembly structure, colors, names, validation properties, file information.

Assembly structure of the mannequin can be navigated via the tree browser. The elements of the assembly can be hidden or shown as essential to inspect the mannequin. The chosen sub-assembly or half can be queried for its properties.

CAD model (complete or selected part or sub-meeting) can be exported to any of supported CAD or mesh formats.

Viewing mesh knowledge

Additional performance is viewing of mesh models with associated data, applied utilizing the mesh visualization part of OCCT.

Supported mesh formats are:

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

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

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

- JT is ISO standard for environment friendly visualization of 3D CAD knowledge.

- glTF is an open normal for 3D assets.

CAD Assistant permits you to view the mesh in wireframe, shaded, and shrink view. If mesh accommodates associated textures, colors, or scalar information, it can be considered with components coloured in accordance to the chosen property. For scalar portions interactive shade scale is shown, providing controls to manipulate the vary of displayed quantities.

Common operations

CAD Assistant for Android is optimized for devices with multi-contact display screen and supplies intuitive manipulation of the 3D view by finger gestures.

Left toolbar supplies buttons for fitting mannequin to window and alternative of normal views. Settings submenu offers access to viewer and software options, file data, and message log.

Files can be opened from local storage (internal memory or SD card). CAD Assistant integrates with Android so that applications supporting file associations will launch it for opening information of related varieties. For instance, you can open STEP file despatched to you by mail by easy click on on attachment in mail shopper.

CAD fashions can be saved in STEP, IGES, or BREP format as CAD information; CAD and mesh models can be saved in PLY, STL, or OBJ format as polygonal information. Save file dialog also permits saving current image of the mannequin to PNG format. If target listing Mail is chosen, the mail shopper will be routinely began with saved file as attachment.

Supported units

CAD Assistant has been examined to work on a broad range of modern tablets and smartphones. Note nonetheless that it helps solely landscape display orientation and this would possibly be inconvenient on telephones.

Application requires OpenGL ES three.zero or OpenGL ES 2.zero with GL_OES_element_index_uint extension.

Limitations

Depending on a gadget, opening massive recordsdata might take time. Devices with low-range graphic processor could be slow on displaying giant models. For giant scenes (hundreds of thousands of triangles), the system may kill the application with no warning due to GPU issues. In basic, recordsdata much less than 50 Mb can be thought of secure for opening on all gadgets.
