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 unformatted bottom level of a single part, cast unit, assembly, part of a connection or a pour object. BOTTOM_LEVEL_UNFORMATTED returns the bottom levels as a length in mm so you can format them and include them into formulas in templates.
Adding _BASEPOINT at
the end of the attribute gives coordinates relative to the base point selected in
the view, and adding _PROJECT at the end gives coordinates relative to the base
point selected as the project base point. _BASEPOINT
uses the current base point in the same way as the workplane uses the current
workplane: If there is no current base point defined, _BASEPOINT
provides values relative to model origin (Global).
You can use this attribute as a user-defined attribute also in part marks and associative notes.
Unlike the BOTTOM_LEVEL attribute, the BOTTOM_LEVEL_UNFORMATTED attribute cannot be formatted through the MarkDimensionFormat.dim file.
