Model Import

Import a multibody model into the Simscape™ Multibody™ environment

Import a multibody model into the Simscape Multibody environment. Use the smimport function for this task. You can import CAD, URDF, and Robotics System Toolbox models. Robotics System Toolbox models require a product license to create. The function parses the model, extracts the necessary data, and reconstructs the assembly using Simscape Multibody blocks for its bodies, constraints, and joints.

URDF models must be in URDF files and Robotics System Toolbox models in rigidBodyTree objects. CAD models must be in a suitable XML format. Use the smexportonshape function to export them as such from Onshape software. Use the Simscape Multibody Link CAD plug-in for Autodesk® Inventor®, Creo™ Parametric, or SolidWorks® models. The plug-in is free to use. See the Simscape Multibody XML schema for an example of a custom export app for models from other sources.
