Hvad er HD3D-filformatet?
En .hd3d-fil er det oprindelige projektformat for Home Design 3D, en app til indretning og boligdesign fra Anuman Interactive (nu en del af Microids). Den gemmer alt, hvad du bygger i en plan: rum, vægge, døre og vinduer, plus eventuelle møbler, dekoration og landskabspleje, du har tilføjet. Åbn filen igen, og du fortsætter designet præcis, hvor du slap.
Under motorhjelmen er en .hd3d-fil et .zip-arkiv. Den samler XML-filer, der gemmer plangeometrien og koordinaterne for hvert placeret objekt, sammen med billedfiler til brugerdefinerede teksturer og miniaturebilleder. XML-layoutet er proprietært, så kun Home Design 3D læser geometrien korrekt, selvom selve ZIP-beholderen er standard.
Sikkerhed og tryghed
RISIKO: 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.

kort fortaltProgrammer der åbner HD3D-filer
.hd3d file or use File > Open to load the project for editing. .hd3d file from the app's project menu. .zip or open it directly to extract the embedded textures and thumbnail images, though the plan geometry stays unusable without the app. .hd3d file to open the project. .hd3d file through the app's import screen; the free version views but cannot save edits. .hd3d file or use the in-app import to open the project; saving changes needs the Gold in-app purchase. Tekniske detaljer
dyb specifikation| 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. |
