This file contains data2smixml(), which is MATLAB code that converts a MATLAB data structure into a Simscape Multibody model. A macro written in Visual Basic extracts CAD assembly information from a SolidWorks assembly into a specific MATLAB data structure. That MATLAB data structure is converted to a Simscape Multibody XML file using the MATLAB function data2smixml(). The resulting Simscape Multibody XML file can be imported into a Simscape Multibody model using smimport().
A Visual Basic macro is provided to show an algorithm for extracting data from a CAD assembly. Assemblies in SolidWorks, Wildfire, Creo (formerly Pro/Engineer), and Inventor can be exported to a SimMechanics XML file using Simscape Multibody Link. If you are using another CAD system, this example can help you write a macro for your CAD system.
Please read the README.txt file to get started.
