How to create single surface from 2 roadway corridors?

Hello!

I have this situation:

As you can see, there is 2 roadways, separated by 150m empty space.

When I try to create the surfaces, the "Add Exterior boundary" makes boundary around the first roadway corridor... and the second roadway corridor stay out of it.

In case I turn off this option there are many extra lines that must be cleared. When i set maximum length in surface parameters, to clear them, there are still extra triangles in inner side of the surface, with lower length than "Maximum length" parameter i can set.

I do not want to turn on the "New surface for each corridor" because in the process of work the roadway corridors will be about 9-10, and will create about 60-70 surfaces ...

My question: Is there a way to make roadway to create surfaces from different roadway corridors (that are with same name in the template)  in same surface?

  • I would try to use the alternate surfaces option. Assign an alternate surface to all of your points on one side of the template and then assign a separate alternate surface to the points on the other side of the template. When you create the surface, make sure that you have the "create alternate surfaces" option checked and you will end up with two separate surfaces that incorporate the appropriate points.
  • I already use alternate surfaces. The question is how to create them in one single surface, but with empty space somewhere in the middle between two roadway corridors.

    The problem is that the roadway creates Exterior Boundary only on the first roadway. And if second roadway have same alternate surface, this part stays out from the Exterior Boundary...

  • I see what you mean now but I don't think you really want to have the part in between included in a proposed surface unless you show them being connected by a proposed line of some sort. If you are trying to show a boundary for the purposes of construction limits, I would suggest just displaying the tin hulls (or dtm perimeter) of both surfaces and cutting out the interior lines and connecting the ends.

    You will want to create the surfaces individually (one corridor at a time) using the exterior boundary option to clean up the extra lines. It sounds like your only problem was creating them at the same time.

    I want to create surface only in open track, the railway stations should be excluded.

    Not only, I want to use single surface.

    Yes.

    I will fulfill some enhancement request for this.

    Tanks, I appreciate your help!

  • The issue here is that the exterior boundary is made from the corridor from the surface and 2 corridors are not combined to create one exterior boundary.

    So you can create both corridors in a single surface but the question is: how to get a suitable exterior boundary to remove all triangles between the 2 corridors ?

    1. create a shape (MicroStation), import it in the surface as exterior

      OR

    2.  create 1 surface per corridor with exterior (S1 and S2) + your single surface (FINAL) without the exterior
      Then copy the exterior only from the S1 and S2 to FINAL with "Append" if feature allready exists
      Then you have to do some manual edit (I advise Feature>Edit points) to delete one side of the exterior to get a clean boundary with no overlap



  • Yes, there is a way.
    But I think it should be easier!

  • Openrail (or Rail Track SS4). Cross sections are created based on the 3D graphics (3D components, terrain model, solids). So corridors are in the drawing and no need to create a surface with both that is triangulated (generating the issue), and no need to manage what is between corridors.
