Convert JCD to another file type
To convert JCD designs to another format, you need JewelCAD or other 3D software.
Convert a file to JCD
To convert other file formats to the "3D Jewelry Model File" file type, you need software like JewelCAD or a similar tool.
About JCD files
The .JCD file format is a highly specialized 3D Computer-Aided Design (CAD) container used to store jewelry models. It contains intricate free-form surfaces, sweeping curves, and parametric gemstone arrays. These files are typically used by professional jewelry designers and manufacturers to draft rings, pendants, and earrings before moving to rapid prototyping. The primary software to create or view these files is JewelCAD Pro (developed by SilkIdeaSign / Jewellery CAD/CAM Ltd). While highly effective for jewelry design, the .JCD format presents a severe vendor lock-in problem. It is a strictly proprietary, closed-source format that requires a costly, niche software license to open. General-purpose 3D suites like Blender or AutoCAD cannot natively read .JCD files. Because of this limitation, users frequently need to convert .JCD files to universal 3D formats. To 3D print or CNC machine the piece, the file must be converted to STL or SLC. For editing in other CAD environments like Rhino, converting to IGES or STEP is recommended. Be aware that converting a .JCD file strips away its parametric history. Dynamic stone arrays and procedural boolean operations are baked into static meshes, meaning you can no longer automatically resize the ring or adjust the prongs. Standard online converters almost universally fail to process .JCD files because they lack the proprietary algorithms required to translate JewelCAD's unique NURBS and gemstone data. If our system detects embedded standard mesh structures or supported underlying data, viewing or converting your file to universal formats may still be possible.
Convert.Guru analyzes your JCD file, detects the exact format, and lets you read the text inside.
If you want to convert JCD file to STL, 3DM, OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D or PLY, you can use JewelCAD or similar software from the "3D Jewelry CAD Modeling" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to JCD, try JewelCAD or another comparable tool in the "3D Jewelry CAD Modeling" category.
The JCD Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our JCD converter.
