At present it is only possible to configure Annotation to show the thread size for a certain type of threaded hole. For example, in our configuration the thread size is always shown for the type "metric fine", and is never shown for the type "metric".
However, if a threaded hole of type "metric" is changed in Machining to have a non-standard thread size then this is not shown in Annotation.
It should be made possible to configure Annotation such that only a non-standard thread size is shown in the dimension of a threaded hole. A threaded hole with a standard thread size should be shown without the thread size.
