Optional Simplification of Subsystem Hierarchy During Model Import

When you generate SimMechanics™ models with the mech_import command, you can now choose certain automatic simplifications of the imported model's hierarchy:

• Bringing all joints in the generated model to the highest level being imported, either the whole model or a subsystem.

• Grouping all welded bodies at each level of the model hierarchy into new rigid subsystems at the same level.

Without these options, the generated model's hierarchy follows the hierarchy specified in the imported XML file, derived from its original CAD assembly.

"What's This?" Context-Sensitive Help Available for Import Physical Modeling XML Dialog Box

This release introduces "What's This?" context-sensitive help for parameters that appear in the Import Physical Modeling XML dialog opened by entering mech_import with no arguments at the command line. This feature provides quick access to a detailed description of the parameters, saving you the time it would take to find the information in the Help browser.

To use the "What's This?" help, do the following:

1. Place your cursor over the label of a parameter.

2. Right-click. A What's This? context menu appears.

   For example, the following figure shows the What's This? context menu appearing after a right-click on the Start time parameter in the Solver pane.

   

3. Click What's This? A context-sensitive help window appears showing a description of the parameter.

Connection Port Block Consolidated to Simscape Library and Documentation

The Connection Port block has been removed from the block libraries of all add-on products dependent on Simscape™ software. When using these dependent add-on products, look for the Connection Port block in the Simscape Utilities library.

The Connection Port block help for these add-on products now directs you to the Simscape block reference.

New Demos

Two new demos have been added.

Model Hierarchy Simplification During Import

You can learn more about how to simplify imported model hierarchy by reviewing the new demo page.

This demo uses two new Physical Modeling XML files, SimplificationExample1.xml and SimplificationExample2.xml. Models generated from these XML files also appear as large graphics examples in Nondefault Hierarchy and Organization of Generated Models.

Reference Coordinate Systems in Imported Physical Modeling XML

With the SimMechanics Link utility, you can export reference coordinate systems that you insert into CAD assemblies. (This feature is not supported on all CAD platforms.) From the exported Physical Modeling XML, you can generate a SimMechanics model with extra Body coordinate systems corresponding to the assembly reference coordinate systems and not associated with CAD constraints and automatically generated Joints.

Using the new GearAssembly.xml file, the new demo page explains how you can use reference coordinate systems to help you manually add a Constraint block to a model after import.
