QuickDraw 3D was Apple's 3D graphics technology for Mac OS and Mac OS X. Its metafiles stored the information needed to describe and recreate three-dimensional objects and scenes.
A qd3d file can contain 3D geometry, object properties and other scene information, including metadata. The associated MIME type is x-world/x-3dmf.
QuickDraw 3D is legacy software and the format is no longer in common use on current systems.
Open the qd3d file with QuickDraw 3D or another application that supports QuickDraw 3D metafiles on a compatible Apple Mac OS or Mac OS X system.
Current macOS versions do not normally include QuickDraw 3D support, so a compatible legacy system or application may be required.
If compatible QuickDraw 3D software can open the file, use that software's export function to save the 3D content in one of its supported formats.
If no compatible application can open the file, conversion is generally not practical.
