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.

Returns the number of tiles in a tile pattern. For example, the Basketweave pattern is made up of eight tiles, so the template attribute returns 8 for a tile surface treatment whose pattern type is Basketweave.
