To combine imperfection cases with each other, there is the 'Group of Imperfection Cases imperfection type.
You can specify there which imperfection cases are to be considered simultaneously and which are to be considered in alternation with each other. For example, the initial sway imperfection in the +Y direction can be combined either with the initial bow imperfection in +y or with the initial bow imperfection in -y. The same applies, of course, to the initial bow imperfection in the +X direction.
You can insert a new line in the table using the
button. The operators "and" and "or" refer to the selected object and the subsequent object.
If you no longer want to consider the individual imperfection cases in the calculation, but only the combinations, you can deactivate them.
