- group a3d_feature_description_thread_module

we can have other data in the thread which contain an attribute to define this value or an option which is used in the thread.
we can have a rotation angle, which creates an offset for the start of the thread.
we can have an option for the use of mirror or of trim with start or end face.
In the case where we have many starts, the thread contains a feature of type NB_START.
In SolidWorks, there is the feature “Stud Wizard” which is about creating a thread on a cylinder. In this feature, there are 2 types of behavior:
the thread can be applied on an already existing cylinder
the creation of the cylinder (=shaft) occurs in the Stud Wizard feature itself. The thread is then applied on the shaft. In the second case, the thread feature also contains a feature definition “shaft” that contains the depth, the diameter, the position and the direction of the shaft.
Also, an undercut can be defined on such a thread.
