If you place an object in the model window, the name of the object is output as an attribute. The name attribute is usually placed within the object. You can place additional attributes of objects in the model window in order to have the relevant information available directly in the model window. The usual procedure is to place attributes with an attribute value that can be seen directly in the model.
However, it may be useful to place attributes that are assigned a value at a later point in time. If, for example, it was defined that, as a rule, the maximum processing time is to be placed to the upper left of the Function object type this may happen even if the attribute value of this attribute has not been entered for all functions. If the value is entered later it is automatically displayed in the model window.
If a placeholder is to be used to make the placement of attributes without a value visible in the model window, you can define that they are to be placed with an attribute name. In our example, Max. processing time: would then be output for the relevant functions, and a value entered would appear behind the colon.
