### Notes

* Make sure that all truss categories (classes) have the same types
* If at least one of the truss categories has less types, name of this type will contain the note “not in all families”

Three options to avoid this:

* Delete that type of truss one by one from all categories using the command *Delete type*
* Delete that type of truss from all categories with one click. Use the command *Delete type*
* Create that type of truss in all categories using the command *Create missing types*
