.MDL is MathWorks Simulink Model

Simulation model created with Simulink, a simulation and model-based design application; contains the block diagram and block properties of the simulation.

MDL files are saved in a plain text format and typically include a list of objects. Each object contains a set of properties and values that are delimited by line breaks.

NOTE: The MDL format was replaced by the .SLX model format with the release of Simulink 2012.

File Type 3 Warcraft 3 3D Model Text File
Developer by: Blizzard Entertainment Category: 3D Image Files Format: Text

Model file used by Warcraft III, a real-time strategy game developed by Blizzard Entertainment; stores a 3D model, including objects, meshes, and textures for buildings and units; allows text-based editing of model properties before generating a binary .MDX file used by Warcraft III.

MDL files use a nested structure to create model properties. For example, a material element may include a layer property which in turn defines a transparent property for the layer.

NOTE: MDL files are the text version of MDX 3D model binary files. They can be converted to the MDX format using the MDLX Converter program. From there, you can use several modeling tools to edit the model.
