3DM Rhinoceros 3D File

The native file format for Rhinoceros 3D (Rhino), a powerful and versatile NURBS-based 3D modeling software. As Rhino’s default format, 3DM is designed to store precise mathematical representations of curves, surfaces, and solids, making it ideal for high-accuracy modeling across industries.

Supported Geometry Types

Known for its precision and versatility, the 3DM format supports a comprehensive range of geometric data types, making it ideal for both organic freeform modeling and technical CAD applications, including:

  • NURBS Surfaces:

    Enables mathematically precise, smooth, and editable surfaces essential for high-end industrial and automotive design.

  • Polygonal Meshes:

    Stores tessellated geometry for 3D printing, rendering, and simulation.

  • SubD (Subdivision Surfaces):

    Allows for flexible, organic modeling with editable subdivision geometry.

  • Instance References:

    Lightweight object copies (not duplicates) that reference a single source, saving memory and ensuring synchronized updates.

3DM File Conversion

Our software solutions enable seamless conversion between 3DM and other major CAD formats (e.g., STEP, IGES, OBJ, DWG, STL). Autoconverter exports only polygonal meshes (STL, OBJ, etc.), suitable for 3D printing and real-time rendering, while Autoshaper preserves NURBS geometry, ensuring superior accuracy for CAD, CAM, and engineering workflows. Both converters can save 3DM files in legacy formats (Rhino 2.X - 7.X) or the latest Rhino 8.X version, ensuring smooth collaboration across different software environments.

STL STereoLithography File

A file format that was developed by 3D Systems, a global leader in the 3D printing industry, to facilitate rapid prototyping and manufacturing. It is widely used in computer-aided design (CAD), 3D printing, and digital fabrication due to its simplicity and broad compatibility. STL files exclusively represent 3D geometry using a triangular mesh, making them lightweight and easy to process.

Key Features of STL

  • Simplicity:

    STL files are easy to create and read by many software applications and 3D printers, as they only contain the coordinates of the vertices and the normal vectors of the triangles.

  • No Additional Attributes:

    Unlike other 3D formats, STL files do not include details such as face colors, textures, transparency, material properties, or named groups. This means that all STL models appear colorless in their raw form.

  • Binary vs. ASCII STL Formats:

    STL files can be stored in two formats:
    • Binary STL
      - The preferred format due to its compact file size, making it more efficient for storage and processing.
    • ASCII STL
      - A human-readable text format that describes each triangle explicitly, but results in significantly larger file sizes.

  • Units of Measurement:

    The STL format does not define a specific unit of measurement, though most applications interpret the coordinates as being in millimeters. If necessary, our STL files converter can perform automatic unit conversions to match your project’s requirements.

STL File Conversion

Autoconverter and Automesher Application are the best tools for converting STL files because they support a wide range of 3D formats, making it easy to convert STL into other file types like STEP, OBJ, or SKP. They ensure high-quality STL mesh conversion, preserving details and accuracy. With advanced automation, they can process multiple STL files at once, saving time and effort. Additionally, they offer optimization features to clean and edit STL models, making them perfect for designers, engineers, and 3D printing enthusiasts.
