Limitations | Supported
PMI | Partially supported

The QIF (Quality Information Framework) format is an ANSI/QIF standard used primarily for representing manufacturing quality data, including product and manufacturing information (PMI), metrology, and measurement results, in a structured, model-based XML format.

QIF is widely adopted in industries that require closed-loop quality processes, such as aerospace, automotive, and precision manufacturing, enabling interoperability between CAD, CAM, and CMM/metrology software.

The file extensions of QIF files that you can expect to be loaded by HOOPS Exchange include:

- .QIF

Note

Our current support for QIF file format is provided as beta version and isn’t available in HOOPS Visualize products/HOOPS Demo Viewer yet.

## How to Import from QIF

Reading `QIF` files follows the same pattern as other formats: configure load parameters, then call the standard load function.

To load a QIF file, use `A3DAsmModelFileLoadFromFile()`. The `A3DParamsLoadData` structure is used to customize the loading behavior:

    A3DAsmModelFile* pModelFile = NULL;

    A3DRWParamsLoadData sReadParam = A3D_MAKE_DATA(A3DRWParamsLoadData);
    sReadParam.m_sGeneral.m_bReadSolids = true;

    // ... set other A3DRWParamsLoadData fields as necessary

    A3DAsmModelFileLoadFromFile("path/to/file.qif", &sReadParam, &pModelFile);

See Simple Load and Export for more about loading model files.

## Limitations

- Topology is not supported for Aggregate13, ArcCircular12, ArcConic12, Extrude23, MeshTriangle, PointCloud, PointCloudSet, Polyline12, Binary Polyline13, Offset23, Ruled23, Spline12, Spline23.
- Transforms are not supported.
- Body wire (Body form=”WIRE”) are not supported.
- Feature nominals semantic is not supported.
- Metadata is not supported, except for the visibility, label, id and UUID from parts.
- xsi:type attribute is not supported and the file won’t be read if it is present in the file.
- Only the following PMI type is supported: Notes. The others only have their label and id read, with links to their associated geometry.
- The assembly structure is not supported. Only the first part of the assembly is read.
