It is convenient to make selections to work with project elements.

Selections are made using the commands of the "load_elements_list" group.

Selections can be made taking into account the type of elements, layers, floors, classes and branches of classes, parameter values, etc.

Then, usually, we request the number of elements in the selection and organize a cycle for processing the elements.

When accessing these commands, you need to use the number of the list of items to select.

By default there are 10 lists, so this number can be from 0 to 9.

Ten lists, from experience, are more than enough to meet the needs of the algorithm in the software module.

But if this is not enough, then with the command "set_tsmax_elemlist_number" you can set any number of these lists.

You can count the current set number of lists with the command "get_tsmax_elemlist_number".
