I have some questions about generating cross section sheets in ORD.
Previously in GEOPAK SS3 we created cross section sheets using the "Create Cross Section" tool from the Corridor toolbar:
The cross sections were placed in sheet models as graphical elements that could be modified, deleted, moved and so on.
These were static cross sections and would need to be generated from scratch following any update to the design model.
One could define the number of cross sections per column and many other settings:
In ORD the concept of cross section generation is approached quite differently using Named Boundaries.
The Civil Cross Section tool is used to place cross section named boundaries:
These boundaries are then used to create cross section sheets:
But these sheets are in fact snapshots or views into the design model and cannot be modified as before.
They are dynamic cross sections that are updated on-the-fly as the design model changes.
My questions are as follows:
1. Have I correctly understood the approach used by ORD to generate cross sections? Am I missing something?
2. How can I define the cross section stacking in the sheet model? What about the many other settings that existed in the SS3 cross section dialog?
3. How do I make modifications to the graphic elements in these dynamic cross sections?
4. Is it possible to generate static cross sections in ORD?
1. This is the correct procedure for creating the cross sections, but the dynamic part of the cross section creation is just using the displayed information from the 3D model to generate the cross section models. It isn't dynamically getting changed as the 3D Model changes. If you make changes, you must recreate (reprocess) the cross sections to create a new cross section model/sheets.
2. The cross section sheets are all controlled by the Sheet Model DGN and how it is created and defined. The sections fit into the sheet border based on how many can physically fit inside the boundary of the border.
3. You should be able to make modifications to any of the graphics using the edit commands. It will not tie back to the elements in the 3D model and change those, only the graphics of the cross section. It is dynamically slicing the model based on what is displayed, but it isn't a dynamic section in the terms that if you change something in the 3D model, the cross sections will change.
4. The cross sections in OpenRoads Designer are in fact dynamic models which contains the 3D information from the 3D model. Since we create the named boundaries, we are creating a dynamic window for referencing the 3D model into the cross section model.

So I went ahead and researched this some more and here is what I found out.
Cross section sheets are generated from named boundaries placed in the design view.
Here is a snapshot of the present model list after cross section sheets have been generated:
As you can see there are 5 sheet models and 5 drawing models created.
They are grouped as model pairs with a drawing model and a sheet model for each cross section.
The drawing model (gray background) references the design 3D model (Default-3D).
The sheet model (white background) references the matching drawing model.
These newly created models do not have any elements of their own.
It is not possible to make any modifications to the referenced cross section elements.
Please forgive me for my lapse regarding my last response. The cross sections in OpenRoads Designer are in fact dynamic models which contains the 3D information from the 3D model. I was still thinking of the OpenRoads cross sections from SS4. Since we create the named boundaries, we are creating a dynamic window for referencing the 3D model into the cross section model.
As to not lead to more confusion, I have edited the response above to reflect this misstatement.
I can see that bentley create a model and a sheet by a single section. I have a model with 30Km of cross sections every 20m. Is there a way to have the graphics of all the sections toghether in an array to do a quick check? We need compare multiple sections simultaneously.
Angel, what version of ORD are you using? I believe that beginning in 2020R1, there is an option for creating a stacked cross section by named boundary (which carried on to later versions as well). I am not sure whether such was possible in earlier versions of the product, but I really do not know of any reason why you could not do so. Personally, I modified Bentleys concepts of this notion to directly fit our needs here.
