WELD_PERIOD1, WELD_PERIOD2
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.
These attributes show the value entered in
the Pitch box in the weld properties. WELD_PERIOD1
shows the value for the welds above line, and WELD_PERIOD2
for the welds below line.
