Configure Simscape Multibody Link


This content refers to Simscape™ Multibody™ Link First Generation software. First-generation features are slated to be deprecated and should be avoided. To prevent compatibility issues in future releases, the Simscape Multibody Link plug-in no longer supports the translation of CAD models into Simscape Multibody Link First Generation models.

Simscape Multibody Link Settings

The Simscape Multibody Link add-in tool provides a Settings option. Use the option to specify:

  • Tolerances — linear, angular, and relative

To access the Settings parameters:

  1. Open the assembly to export.

  2. In the menu bar, click Add-Ins > Settings.

The Settings dialog box opens.

Dialog Box

The dialog box contains two panes:

  • Assembly Tolerances — Specifies linear, angular, and relative tolerances of exported assembly.

Enter the export tolerances for a CAD assembly. During the conversion of CAD constraints to Simscape Multibody joints, Simscape Multibody Link compares the spacing, alignment, and relative numerical errors with the export tolerances.
