displaying threads

I have a question.
when converting a part to step, the threads are no longer displayed; is there any way to avoid this ?

Do you mean the graphic of a thread in shaded view?
If so, then the answer is no.
Graphical display of threads is nice but not an engineering requirement, not is there any standardized way of communicating the graphic.
There is another post on the topic.
Please search to review.
