About .rlf Files
RLF files are binary files used for 3D relief modeling in ArtCAM.
They use the MIME type application/octet-stream, which is a common marker for binary data.
- Main Use: Storing detailed 3D relief models for design and manufacturing.
- Software: Primarily opened and edited with ArtCAM.
- Additional Uses: May be used in industries like CNC machining where relief patterns are needed.
According to FilExt.com, the RLF format is specific to applications that generate 3D relief models.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an RLF file?
An RLF file is a proprietary 3D relief file originally associated with ArtCAM software (now discontinued). It stores height map data and 3D geometry used primarily for CNC machining, woodworking, and engraving. These files allow designers to save complex textures and relief models for manufacturing.
How do I open an RLF file?
You can open RLF files using Carveco, which is the spiritual successor to ArtCAM and maintains support for the format. If you have a legacy installation of Autodesk ArtCAM or Delcam ArtCAM, those programs will also open the files natively.
Can I convert RLF files to STL for 3D printing?
Yes, but you typically need ArtCAM or Carveco to perform the conversion. Open the RLF file in the software and use the Export or Create Triangle Mesh function to save the relief as an .stl or .obj file, which can then be used in slicers for 3D printing.
Why can't I open my RLF file in Blender or AutoCAD?
Most general-purpose 3D software like Blender, AutoCAD, or SketchUp cannot import RLF files directly because the format is proprietary. You must first export the model as a standard mesh (like STL) using ArtCAM or Carveco before importing it into other design tools.
Is ArtCAM still available to edit RLF files?
No, Autodesk ArtCAM was officially discontinued in 2018. Users looking to edit or create RLF files usually switch to Carveco, which was created by former ArtCAM developers and functions very similarly.
What is the MIME type for RLF files?
Because RLF files contain proprietary binary data, they are generally classified under the generic MIME type application/octet-stream. You can learn more about how systems handle generic binary files by visiting the application/octet-stream page on mime-type.com.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
