Hi,
Inga, when I wrote that I had used Microstation tools to reverse horizontal elements I meant the Change Curve Direction tool.
The reason for which reverse tool for Civil Geometry was removed in SS3 is that with OpenRoads Technology released civil geometry is much more complex. Horizontal elements are base elements for vertical geometry (and you can have multiple vertical alignements assigned to a single horizontal element) and than are used to define corridors. Saying that, using reverse command for horizontal civil elements would possibly cause problems in your vertical alignments and corridors.
Nevertheless, reversing horizontal element should be possible when it is just a horizontal with no vertical alignments or corridors assigned, unfortunately it is not. But I fully understand the reasons for that.
