Install the Simscape Multibody Link Plugin
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|
|PTCCreo||1.0 to 6.0||R2008b and higher||3.0 and higher|
|Autodesk Inventor||2009 to 2021||R2009b and higher||3.0 and higher|
Autodesk Inventor 2022 is not supported.
Your MATLAB® and CAD installations must have the same system architecture, such as Windows 64-bit.
Step 1: Get the Installation Files
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.
Step 2: Run the Installation Function
Run MATLAB as administrator. For more information, see How to Make a Shortcut to Run MATLAB as Administrator.
Add the folder in which you saved the installation files to the MATLAB path. For example, you can use the
At the MATLAB command prompt, enter
zipnameis the name of the ZIP file, such as
Step 3: Register MATLAB as an Automation Server
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 a Windows® command prompt window running in administrator mode. At the command prompt, enter
Step 4: Enable the Simscape Multibody Link Plugin in a CAD Application
Before you can export a CAD assembly, you must enable the Simscape Multibody Link plugin on your CAD application. To do this, see:
Importing CAD Files from Applications Not Supported by Simscape Multibody Link
To import an Onshape® CAD assembly model into the Simscape Multibody, you can use the
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
smimportfor more information.
