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.

This attribute shows the default weld size that you define in drawing weld properties. This attribute is for template purposes only. It can be found under the Drawing content type in Template Editor.

The Weld size limit setting in drawing properties and drawing view weld properties filters welds and weld marks of the defined weld size and smaller out of the drawing.
