Major Bug Fixes for SimMechanics 2.1

Code generation by right-click now works

Generating code from a SimMechanics block by right-clicking, then selecting Build subsystem, no longer causes the model to crash.

Code generation error with block names fixed

If a SimMechanics block name started with a space or spaces, then a number as the first nonspace character, generating code from the model produced an error. This bug has been fixed.

Error dialog no longer triggers segmentation faults

Simulation errors in SimMechanics that open the Simulink error dialog no longer cause SimMechanics to crash.

Joint Spring & Damper block copying bug fixed

Copying a Joint Spring & Damper block in a SimMechanics model no longer causes an error when the model is updated or started.

Joint Stiction Actuator lock mode bug fixed

The Joint Stiction Actuator, when connected to a Joint with multiple prismatic or revolute primitives, did not always lock and switch to static friction properly. This bug is now fixed.

Kinematics mode errors fixed

The Kinematics motion analysis mode is designed for machines with closed topologies only. Attempting to analyze an open-topology machine in some cases caused SimMechanics to crash. Using Kinematics mode incorrectly now generates an error message.

In some cases, the Kinematics mode entered an infinite loop while reporting information on constraints. This bug is also fixed.

Periodic Point-Curve Constraint no longer causes MATLAB to hang

You can configure the Point-Curve Constraint block to take a closed curve specified as a periodic spline. This setting no longer causes MATLAB to hang.
