NX Threaded Hole not represented as expected in the model and drawing section view

When a Threaded Hole feature passes through the same body twice, as in the case of  horizontal hole through a 'U' shaped model, the symbolic thread representation (the dashed lines) are only created on the faces of the first instance where the hole intersects the body.
If a section view is created through the centerline of the hole in Drafting, the thread representation is also only shown for the first intersection between the hole and the body. This is the as-designed behavior.

Solution

To get the required thread representation, in the model and the drawing, rather than creating a hole feature that passes through the same body twice, create separate hole features for each instance where the hole intersects the body. 
This is considered best practice and will give the expected visual representation of the thread, as well as ensuring that the appropriate thread values are included in any Hole Callout annotation.
