#-->RESULT ecode:intValue objid:idValue

Parameters ​

  • modelid (idValue) - the ID of the model in which the object should be created
  • classid (intValue) - he ID of the class of which an instance should be created
  • objname (strValue) - the name of the instance

Open a new model and execute the script. The script ascertains the ID of the class "Aktivität" and the ID of the active model. With these IDs it creates a new instance.
