Configure SimMechanics Link

SimMechanics Link Settings

The SimMechanics™ 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:

  1. Open the assembly to export.

  2. In the menu bar, click Tools > SimMechanics Link.

  3. 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 SimMechanics joints, SimMechanics Link compares the spacing, alignment, and relative numerical errors with the export tolerances.

Angular tolerance1e-005Smallest significant angle difference1e-5Units used in assembly
Relative roundoff tolerance1e-012Smallest significant relative numerical difference1e-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, SimMechanics Link exports all reference coordinate systems.
