ArtCAM was officially discontinued by Autodesk in 2018. Because of this, "official" standalone converters are rare. Most users now rely on manual export methods or the successor software, Carveco, which was built on the original ArtCAM codebase. Conversion Methods Reliefs (.ART to .STL/.OBJ) If you need to move 3D designs to other software:
Create Mesh tool: In ArtCAM Standard or Premium, use "Create Mesh" to export the relief as an .STL format.
Third-party aid: Communities like Carveco Tips often help users with one-off .RLF to .STL conversions. Vectors (.ART to .DXF) To move 2D lines:
Export Vectors: Select your vectors, go to the Vector menu, and choose Export. Select DXF (AutoCAD) to save them in a format readable by almost any CAD program. Version Upgrading
Old to New: Files from older versions (e.g., ArtCAM 2008) often won't open directly in 2017/2018. The recommended workaround is exporting the old file as an .STL and importing it into the newer version. artcam file converter
ArtCAM files, typically using the .art extension, are proprietary CAD/CAM models that can be converted or exported into various formats for use with other CNC software or 3D printers. Since Autodesk discontinued ArtCAM in 2018, file conversion has become essential for users transitioning to newer software like Carveco, which is built on the original ArtCAM codebase and natively supports legacy files. Common Export & Conversion Methods
Most "conversions" are performed using the Save As or Export functions within the ArtCAM software itself to make the data compatible with other platforms:
3D Models to STL: To use an ArtCAM relief in 3D printing or other 3D software, you must convert it to a triangular mesh. Go to the Relief menu, select Export Relief, and use the Create Triangular Mesh tool to save the file as an .stl.
2D Vectors to DXF: To move 2D designs to programs like AutoCAD or Adobe Illustrator, select your vectors, go to the Vector menu, and choose Export. Select DXF (AutoCAD) File (*.dxf) from the "Save as Type" dropdown.
Legacy Version Conversion: There are specific batch converters (such as one for ArtCAM 2015 R2) designed to convert older .art files so they can be opened in newer versions of the software. Compatible Software for Opening ArtCAM Files Title: Development of a Dedicated File Conversion Utility
If you no longer have access to ArtCAM, a few specific programs can open or convert these files:
Carveco: This is the primary successor to ArtCAM. It can open most legacy proprietary files, including .art, .3dp, .rlf, and .3da.
Delcam ArtCAM: Original versions of the software are the most reliable way to open and re-save files into neutral formats like STL or OBJ.
Post-Processors: For CNC machining, ArtCAM converts toolpath data into G-code (often .tap or .nc files) using specific post-processors tailored to your machine's controller. Import a 3D file or STL into ArtCAM - Autodesk
6. Limitations & Challenges
| Challenge | Explanation | |-----------|-------------| | Proprietary encryption | .art format includes compressed binary sections; no open-source decoder exists. | | Loss of parametric data | Converted STL loses vector, layer, and toolpath information. | | Toolpath loss | No direct conversion of ArtCAM toolpaths to other CAM; must recreate. | | Texture/color loss | Materials, bitmaps, and render settings are not retained. | | Scale/units | Mismatch between ArtCAM's default units (inches/mm) and target software. | ArtCAM was officially discontinued by Autodesk in 2018
2. Technical Analysis of the ArtCAM File Format
To build an effective converter, one must understand the structure of the source files.
What Gets Lost in Translation?
An ArtCAM file converter is not a magic wand. When you convert from .art to a universal format, you lose specific metadata:
| Feature | Retained? | Notes | | :--- | :--- | :--- | | 3D Relief Geometry | Yes | Fully retained in STL or OBJ. | | Vectors (2D lines) | Yes | Export as DXF. | | Layer Colors/Names | No | STL does not support layers. | | Toolpath Strategies | No | Must be re-created. | | Bitmap Textures | Partially | Convert texture map separately as .PNG. | | Undo History | No | You get the final result, not the process. |
Limitations & Risks
- Proprietary project features (parametric history, custom toolpaths) may not survive conversion.
- Loss of editability: meshes replace parametric surfaces and history.
- Potential for scale/unit mismatches causing machining errors.
- High-resolution reliefs can produce very large files that challenge downstream software or CAM processors.
- Some formats (STEP/IGES) may require conversion via intermediate NURBS-capable software, increasing complexity.
Part 6: Red Flags – What to Avoid
When searching for an "ArtCAM file converter," you will find many dangerous traps.
- "Free Online ArtCAM Converter" (Scam): These sites either serve malware or simply steal your proprietary designs. Never upload proprietary CNC files to a random web server.
- "Magic EXE" files on forums: Discontinued software attracts hackers. EXE files claiming to convert all versions are almost always ransomware.
- CloudConvert / Zamzar: These are excellent for images and videos, but they explicitly do not support proprietary CNC formats like .art or .rlp. Do not waste your time.
1.2 Problem Statement
The discontinuation has created a "Legacy Data Crisis." Companies holding proprietary .art project files face significant barriers to retrieving intellectual property. Without a licensed copy of ArtCAM, these files are effectively digital garbage. Existing conversion tools often focus only on standard mesh formats, ignoring the specific layered structure and vector data unique to ArtCAM.
