2023-10-25 - twin 23.10

We are pleased to announce that twin version 23.10 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.

Note

When opening projects created with twin before version 23.8, the window layout may be incorrect. To fix this, please click on Reset Window Layout in the Window button in the toolbar.

New features

  • It is now possible to change the size of a box
  • You can now move multiple selected simulation components in the Simulation Components window into a group
  • You can now edit multiple selected simulation components of the same type at once
  • You can now duplicate a group of simulation components
  • We have added a new simulation component Object3DFileSource that allows adding 3d objects from CAD files that can be defined during simulation
  • If IO definitions in the PLC have changed, you can now easily replace existing IOs in the simulation component PLCConnector using the Datapoint Browser

Improvements

  • The changelogs are now available online
  • A link to the online changelogs was added to the twin Updater
  • The twin Updater shows more clear messages when twin is running while trying to update
  • When downloading the current version in the twin Updater it is not possible to press the download button again
  • When 3D objects with rigid body behavior None have zero mass, an error is shown in the Assembly Tree window and the Selected 3D Object window
  • The simulation performance was improved when there are many 3D objects with rigid body behavior Static or Kinematic
  • In the API the signature of the collision event has changed. The collision event now also includes the collision points.
    Warning

    This is a breaking change. You need to adapt and rebuild your code with the current SDK.

Fixed issues

  • The IO values in the Simulation Component Diagram window where not removed when the corresponding setting was disabled
  • When the simulation component VacuumGripper was deleted, gripped 3D objects may not be released
  • When the simulation components Object3DSink was deleted, 3D objects still get deleted
  • Under certain circumstances, some faces of 3D objects are not displayed correct in the web browser
  • When moving 3D objects out of a group which is assigned to the simulation component Colorizer, the color of the 3D object was not set back to its original color
  • Under certain circumstances, the simulation components KinematicCylinder and DynamicCylinder were not enabled when the simulation was stopped and restarted
  • Fixed an issue which results in an instable behavior of the VacuumGripper when the local coordinate system of the 3D object is far away from the collision point
  • Fixed an issue which causes twin to crash, when the simulation engine was changed to None in the settings
  • The simulation component VacuumGripper showed a wrong error in the Selected Simulation Component window under certain circumstances
