CSM Character Studio Marker File

A proprietary file format for Character Studio, a software developed by Autodesk for creating 3D animation content with an internal bone structure. Character Studio is a tool that allows you to create realistic and expressive 3D characters, using a skeleton system and motion capture data. Here are some of the key features and benefits of CSM:

  • Bone and Marker Information: CSM is a unique and advanced format for 3D animation content, as it can store not only the geometric information of the 3D meshes, but also the bone and marker information of the 3D characters. Bones are the internal structure that define the shape and movement of the 3D characters, while markers are the external points that can be attached to the bones and used to track the motion of the 3D characters. Bones and markers can help you create realistic and expressive 3D animations.
  • CSM File Converters: Autoconverter and Automesher Application can load and import CSM mesh data, thanks to the open asset import library. Our software enables you to effortlessly convert and save the imported character CSM data into your primary 3D file format, such as FBX, DAE, STL, SKP, OBJ, and others, making it ready for processing in your preferred 3D modeling software.


A file format for the efficient storage and exchange of 3D city models and landscapes. It has the following benefits and features:

  • Optimized CityGML: The CityJSON format is based on CityGML, which is an OGC standard for representing and exchanging 3D urban data. However, CityJSON is optimized for simplicity and efficiency, using JSON instead of XML as the underlying syntax. CityJSON reduces the file size and complexity of CityGML files, making them easier to process and manipulate.
  • 3D City Data: The CityJSON files can store 3D city models and landscapes, which are composed of various city objects, such as buildings, roads, bridges, vegetation, etc. Each city object has a name, a geometry, and a set of attributes. The format also supports nested hierarchy, reusable geometry component instances, and custom materials with texture images, which enhance the realism and detail of the 3D city data.
  • CityJSON Converter: Autoconverter allows you to import and export CityJSON files, and convert them into various other 3D mesh file formats, such as STL, OBJ, SKP, 3DS`, etc. Our software supports the reading and writing of CityJSON geometries with custom attributes, which preserve the semantic information of the 3D city data.
