Convert CSM to 3DM

CSM to 3DM Conversion

With our tools, changing CSM to 3DM is a breeze - follow these simple 3 steps:

  1. Download & Install:

    Convert your CSM files to 3DM format seamlessly using Autoconverter - simply install and launch the software on your system.

  2. Import CSM File:

    Either click Open... to browse for your .csm file, or drag and drop it anywhere in the application window.

  3. Export to 3DM Format:

    Use Save As... to specify both location and filename (with .3dm extension) for your exported file.

Frustrated with CSM to 3DM conversion? These step-by-step guides simplify CSM files conversion:

CSM Character Studio Marker File

The proprietary format for Autodesk's Character Studio, designed to store animated 3D characters with complete bone structures, skin weights, and motion capture data. As the native format for this legacy animation toolkit, CSM files preserve skeletal rigs, biped configurations, and facial animation systems that powered realistic character movement in 3ds Max workflows.

Key Features of CSM

  • Animation Data:

    Preserves motion capture sequences and keyframe animations.

  • Facial Animation:

    Supports morph targets and facial expression controls.

  • File Interoperability:

    Native to 3ds Max workflows (1995-2010 era).

  • Legacy Status:

    Replaced by FBX/BVH for modern character pipelines.

CSM File Conversion

Autoconverter and Automesher Application support CSM file import through open asset libraries, enabling seamless conversion of Character Studio's bone, animation, and mesh data into modern formats like FBX, DAE, STL, SKP, and OBJ. Automate Character Studio conversions to FBX/GLB with our professional CSM converters today!

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.
