This advanced option must be set in an initialization (.ini) file.

Set this advanced option to TRUE to sort part and assembly part lists in templates so that the main part of the assembly appears at the top of the list, immediately after the assembly.

This advanced option is needed in row rules, where rule is read after sorting.

If you add this advanced option to the options.ini file under the current model folder, you need to reopen the model to activate the new value. If it is set in another .ini file, you need to restart Tekla Structures.
