As a result of attribute-based modeling, special modeling cases can arise. The following describes how such cases are handled:
An object lies completely outside the defined time column
If, for example, the start attribute and the duration are outside the defined time column or the start time exceeds the end time, a marker in the form of a double peak is displayed at the border of the column header:
If you position the mouse pointer over this marker, a note is displayed.
An object lies partially outside the defined time column
If, for example, the start of an object is outside the defined time column, but the end is inside it, the object is partially displayed and the marker in the form of a double peak is displayed at the border of the column header:
If you position the mouse pointer over this marker, a note is displayed.
Positioning and dimensioning attributes cannot be used
Under certain conditions, the system is not able to read required attributes.
The user does not have read access for objects
As the position- and/or dimension-relevant attribute values cannot be read, the objects are placed according to their graphic coordinates. The user cannot select objects and can neither move them nor change their size.
The position- and/or dimension-relevant attributes are not permitted by the current filter.
The model is opened in read-only mode and a corresponding message is displayed. As the position- and/or dimension-relevant attribute values cannot be read, the objects are placed according to their graphic coordinates.
The object type or its symbol is not allowed by the current filter.
As the position- and/or dimension-relevant attribute values cannot be read, the objects are placed according to their graphic coordinates. The objects cannot be selected and they are displayed as a gray border.
Positioning and dimensioning attributes are not specified
The attributes are not automatically specified, for example, when opening the model.
As the position- and dimension-relevant attribute values do not exist, the objects are placed according to their graphic coordinates.
The objects are provided with an information icon ().
The time column is being configured for the first time
If the time column is being configured for the first time, the user is asked whether the attributes of the objects placed in the time column, which have not yet been specified, are to be specified automatically.
