The qt3d file extension is associated with Qt, a cross-platform application framework developed by The Qt Company. Qt supports application development for Windows, Linux, macOS, Android and other platforms.
A qt3d file stores 3D data for use within Qt software. It belongs to the Qt ecosystem rather than being a general-purpose 3D interchange format, so its contents are normally interpreted by the Qt tool or application that uses it.
On Microsoft Windows, open the qt3d file with the Qt SDK or the Qt-based application that created it. The file may not be meaningful when opened in a general-purpose 3D viewer.
There is no generally applicable converter for the qt3d file format. If the associated Qt tool provides an export function, use that tool to export the 3D data to one of its supported formats.
