Answer:
These cross-section elements belong to an inserted cross-section; therefore, they cannot be edited individually.
If you want to modify the individual elements of an inserted cross-section, you can do it in several ways:
- Selecting another cross-section from cross-section library
If you edit the cross-section or select another one, the corresponding elements will be changed as well. Click the "Parametric Input" button to modify the specified cross-section properties. This option is especially useful if you want to keep the base geometry and symmetry of the original cross-section. The sheet thickness and total height or width can be adjusted very easily this way.
- Reducing Cross-Section into Individual Elements
This way, you can create single, independent elements from the inserted cross-section. Subsequently, they can be edited like elements created normally. This procedure is useful, for example, if you want to change the base geometry of the original cross-section.
