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 dimensions of bent reinforcing bars based on the mappings in the rebar_schedule_config.inp file, located in the system folder defined with the advanced option XS_SYSTEM. These mappings are environment-specific by default. You can modify them to suit your company or project needs.

DIM_TD shows the diameter of the bending cylinder, DIM_R shows the radius. DIM_R_ALL shows multiple radiuses.
