Qu'est-ce que le format de fichier HD3D ?
Un fichier .hd3d est le format de projet natif de Home Design 3D, une application de conception de maison et d'intérieur d'Anuman Interactive (faisant désormais partie de Microids). Il enregistre tout ce que vous construisez dans un plan : pièces, murs, portes et fenêtres, ainsi que tous les meubles, la décoration et les aménagements extérieurs ajoutés. En ouvrant à nouveau le fichier, vous reprenez la conception exactement là où vous l'aviez laissée.
Sous le capot, un fichier .hd3d est une archive .zip. Il regroupe des fichiers XML qui stockent la géométrie du plan et les coordonnées de chaque objet placé, ainsi que des fichiers images pour les textures personnalisées et les vignettes de prévisualisation. La structure XML est propriétaire, donc seul Home Design 3D lit correctement la géométrie, même si l'enveloppe ZIP elle-même est standard.
Sécurité et sûreté
RISQUE : LOWAn .hd3d file is a passive project document, not an executable, so opening one cannot run code. It is a ZIP container, so as with any archive a malformed file could in theory trip a bug in an unpacker, but normal projects opened in Home Design 3D carry no meaningful risk. Only open files from sources you trust.
Détails du format
en brefProgrammes qui ouvrent les fichiers HD3D
Windows3 apps
Home Design 3D
Payant Install the desktop edition, then double-click the .hd3d file or use File > Open to load the project for editing.
Home Design 3D on Steam
Payant Buy and install through Steam, launch it and open the .hd3d file from the app's project menu.
Any ZIP tool (7-Zip)
Open-source Rename the file to .zip or open it directly to extract the embedded textures and thumbnail images, though the plan geometry stays unusable without the app. 
macOS2 apps
The Unarchiver
Gratuit Use it to unpack the underlying ZIP and pull out any texture or preview images stored in the project.
Home Design 3D
Payant Install from the Mac App Store, then double-click the .hd3d file to open the project. 
Android1 app
Home Design 3D
Freemium Install from Google Play, then open the .hd3d file through the app's import screen; the free version views but cannot save edits.
Home Design 3D
Freemium Install the app, tap the shared .hd3d file or use the in-app import to open the project; saving changes needs the Gold in-app purchase. Détails techniques
spécifications approfondies| Encoding | Binary ZIP container |
| Byte order | N/A (ZIP structure defines its own little-endian fields) |
| Container | ZIP archive holding XML data files and image assets |
| Compression | DEFLATE (standard ZIP compression) |
| Typical size | A few hundred KB to several MB depending on furniture, textures and screenshots stored |
| Structure | A renamed ZIP archive. Inside are XML files describing the plan geometry (rooms, walls, doors, windows, spatial coordinates of placed objects) plus image files used for custom textures and preview thumbnails. |
| Integrity | Per-entry CRC-32 checksums as defined by the ZIP format |
| Platforms | Windows, macOS, iOS, Android |
| Notes | The internal XML schema is proprietary and undocumented. Because the wrapper is a plain ZIP, the archive can be opened with any ZIP tool to extract textures and thumbnails, but the geometry XML is only meaningful to Home Design 3D itself. Export of .hd3d requires the paid version; import works in the free version but without the ability to save changes. |
| Developer Note | Home Design 3D is published by Anuman Interactive, a French studio now part of Microids. |
