Using this option, you can define criteria of element selection (by element type).
Open the Filters - element selection dialog from:
- Menu: Formwork Drawings > Tools > Element selection by type
- Ribbon: ASD - Model > Tools > Element selection by type
- Toolbar: Tools > Element selection by type
- Command line: RBCX_TOOL_SELECT_EL.
Select any combination of elements, materials, and stories (the 
symbol displays) to specify selection criteria. For example, to select all RC beams belonging to stories 4 and 5 of a structure:
- Under Elements, select Beams
- Under Materials, select Concrete
- Under Stories, select Story 4 and Story 5.
To select all options in a field, click All. To clear the selection of all options in a field, click None.
Use the options at the bottom of the dialog to save the filter settings. To save a filter, select an element selection, type its name in the Name field and click Save. You can perform the following operations for user-defined filters:
- select from the drop-down list
- delete from the drop-down list (select a filter and click Delete)
- modify existing filters.
The Save option for filters is very helpful when a building is being modeled, because after you have saved the settings you do not have to redefine a specified element selection.
