twin 25.8

Released on 2025-08-27

We are pleased to announce that twin version 25.8 is available. In this document you will find all the new features, improvements and fixed issues. If you encounter any problems during installation or during execution, please contact us by e-mail to info@digifai.com.

New features

  • We have added a new simulation component called KinematicTransformMover that allows any 3D object to be freely transformed.
  • RobotControllerConnector: Yaskawa MOTOMAN YRC1000micro controllers are now also supported.

Improvements

  • PLCConnector: We have updated the interface to Siemens S7-PLCSIM Advanced to take advantage of the latest stability improvements in Siemens S7-PLCSIM Advanced.
    Note

    Due to a change in the new version of Siemens S7-PLCSIM Advanced the PLCConnector cannot connect to versions older than 6. If you are using Siemens S7-PLCSIM Advanced, please update your installation to at least version 6.

  • RobotControllerConnector: Raw joint values are now also published in the Yaskawa MOTOMAN YRC1000micro driver.
  • Pop-up windows now appear at the same window location, as they where closed before.
  • We have updated the rigid body simulator PhysX to the latest version which results in a more stable simulation.
  • Zoom To Object in the right-click menu in the Assembly Structure window is now animated.
  • We have improved the documentation of the twin Mirror. Please see the API documentation for more details.
  • We have improved the process of requesting licence activation from within twin.
  • We have removed the deprecated 3D View, which was used until twin 24.4.

Fixed issues

  • The 3D model wobbled when it was rotated around the mouse pointer.
  • The Measure tool in the 3D View window was not closed, when a new project was opened.
  • When the link behind More Help ... in the New Simulation Component window was invalid, twin crashed.
  • When creating a new path, the UpVector was sometimes invalid.
  • When the arrow-keys where used to move a container in the Simulation Component Diagram view, twin may crashed.
  • It was possible to assign a mass of zero to a dynamic 3D object.
  • Importing a twin project with enabled diagram containers failed under certain circumstances.
  • Using a source to add boxes or spheres to the simulation was slow, when the project was opened from a network share.
  • CollisionObserver and CollisionSink: Collisions between static and kinematic 3D objects where not detected correctly.
  • CollisionSink: The sink did not always remove 3D objects, when it was enabled by an output of a PLCConnector.
  • Sequence: The name of the target position in the Move robot block was sometimes wrong.
  • PLCConnector: If there were duplicate data points in the PLC, the Datapoint Browser did not display any content.
  • DynamicRotationMover: The simulation freezed, when the Rigid Body Behavior of the MovingObject3D was changed from kinematic to dynamic.
  • Sequence: < and > did not work correctly in the If statement block.
  • Sequence: The width of some blocks was not updated correctly.
  • GenericRobotController: Changes in the Simulation Time Step in the Settings view where not applied.
  • twin Mirror: We have fixed some issues when getting and setting the position of the camera in the JavaScript API.
  • twin Mirror: We have fixed some issues when moving, zooming or rotating the 3D view on a touch screen.
