Configure Simscape Multibody Link

Warning

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
Coordinate systems to export

To access the Settings parameters:

Open the assembly to export.
In the menu bar, click Tools > Simscape Multibody Link.
Click 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.
Export Coordinate Systems — Determines what coordinate systems to export.

Assembly Tolerances

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.

Field	Default Value	Purpose	Default	Unit
Linear tolerance	`1e-005`	Smallest significant length difference	1e-5	Units used in assembly
Angular tolerance	`1e-005`	Smallest significant angle difference	1e-5	Units used in assembly
Relative roundoff tolerance	`1e-012`	Smallest significant relative numerical difference	1e-12	—

Export Coordinate Systems

Specify which reference coordinate systems to export. The coordinate systems are independent of constraints between parts. Options include:

Do not export coordinate systems — Export no coordinate systems.
Export only CSs with this prefix — Export only coordinate systems with the specified name prefix. If the prefix field is empty, Simscape Multibody Link exports all reference coordinate systems.
