This content refers to Simscape™ Multibody™ 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 First Generation models.
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, select Simscape Multibody Link > Settings. In certain SolidWorks® versions, this option may appear under the Tools menu.
The Settings dialog box opens.
The dialog box contains four panes:
Message — Describes the purpose of the dialog box. The Message box is inactive.
Solve Subassemblies Using — Determines whether to export a subassembly as a rigid or flexible system.
Assembly Tolerances — Specifies linear, angular, and relative tolerances of exported assembly.
Export Coordinate Systems — Determines what coordinate systems to export.
Select how to export CAD subassemblies.
Component properties — Treat rigid subassemblies as rigid, and flexible subassemblies as flexible.
Flexible settings — Treat all subassemblies as flexible. This setting applies does not affect the original CAD 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.
|Linear tolerance||Smallest significant length difference||1e-5||meter (m)|
|Angular tolerance||Smallest significant angle difference||1e-5||radian (rad)|
|Relative roundoff tolerance||Smallest significant relative numerical difference||1e-12||—|
Specify which reference coordinate systems to export. The reference coordinate systems are independent of mates 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.
