Multibody™ Link is a plugin that you can install on CAD applications to export assembly models
Multibody. Specifically, the plugin exports a CAD assembly model as an XML file and body
geometry files that you can convert into Simscape
Multibody models using the
smimport function. The plugin supports:
Make sure your software meets the requirements:
|CAD Software||Release Supported||MATLAB Release||Simscape Multibody Release|
|SolidWorks||2001Plus and higher||R2008b and higher||3.0 and higher|
|PTC Creo||1.0 and higher||R2008b and higher||3.0 and higher|
|Autodesk Inventor||2009 and higher||R2009b and higher||3.0 and higher|
Your MATLAB® and CAD installations must have the same system architecture, such as Windows 64-bit.
Go to the Simscape Multibody Link download page.
Follow the prompts on the download page.
Select and save the ZIP and MATLAB files that match your MATLAB version and system architecture, such as release R2020b and Win64 (PC) Platform. Do not extract the ZIP file.
Run MATLAB as administrator. See How to run MATLAB as administrator for more information.
Add the folder in which you saved the installation files to the MATLAB path. For example, you can use the
addpath (MATLAB) function.
At the MATLAB command prompt, enter
zipname is the name of the ZIP file, such as
Each time you export a CAD assembly model, the Simscape Multibody Link plugin attempts to connect to MATLAB. To enable the connection, you must register MATLAB as an automation server. You can do this in two ways:
Open a MATLAB session in administrator mode. At the MATLAB command prompt, enter
Open an MS-DOS window running in administrator mode. At the command
Before you can export a CAD assembly, you must enable the Simscape Multibody Link plugin on your CAD application. To do this, see:
If you use a CAD application other than Onshape, SolidWorks, PTC Creo, and Autodesk Inventor, you can create a custom model export application based on the Simscape Multibody XML schema. This approach requires some knowledge of XML. See the schema web page for more information.
You can also create a Simscape
Multibody model from a URDF file or Robotics System Toolbox™ model. See the
smimport for more
