In half views, the symmetry line is set in front by default.
If the part is not rotationally symmetrical (which, strictly speaking, is the case for most of our parts and assemblies), the line of symmetry must be deselected in the view on the drawing and a centerline displayed instead.
This cannot be displayed in the halfview.
Current workaround:
1. Switch the half view to full view.
2. Show the axis (which is on the symmetry line)
3. Switch view to half view again.
Wanted:
Additional option in the half view settings for centerline.
