This is a template attribute. Template attributes can be used in filtering, or to retrieve data from the model to use in drawings and reports. For example, when you create a report, Tekla Structures replaces the attributes added in the report template with the corresponding object property values.
Shows the top level of a single part, cast unit, assembly, part of a connection or a pour object.
Top level takes the unit and accuracy from MarkDimensionFormat.dim. You can modify the settings in MarkDimensionFormat.dim in the dimension properties in the drawing property pane in an open drawing.
The datum level only affects the
TOP_LEVEL attribute when
Location by is set to
Model origin or to the project base point that is in the model origin.
You can use this attribute as a user-defined attribute also in part marks and associative notes.
This attribute returns the value as text, so you cannot use formulae with this attribute. Use TOP_LEVEL_UNFORMATTED instead.
