Tekla Structural Designer applies patterning to beam loads automatically. However, if you need to apply patterning to slab loads for slab design or other purposes, you must update the load patterns manually.

1. On the Load tab, click Update Patterns.
2. In the Properties window, select each pattern and adjust the loading status of the existing beams and slabs.
3. To switch the loading status of a slab, click the slab in the model.
