import rail from graphics (cad) file into Openrail

Hi,

I want to import existing rails from a suvey (cad) file to open rail but cannot find answer to it. there are videos about importing rail from CSV /ASCII file . But i dont have ASCII/CSV files.

  • So what do you have? 3D linestring?

    In this case it is not mandatory to import. You can reference and use them as they are to create regression line from rails, project on the profile.µ

    If you want to do more such as attaching a feature definition and name the rails, you can just copy from the reference to a DGN 3D model.



  • I’m having similar issues. I am trying to follow how I worked in v8i BRT but its not really the same.

    I also have rail strings what I’d like to create a CL from, regress the CL, then create Rails from CL. My workflow I’m trying is:

    Array a point up each rail string, 1m distance, so spoof the survey points its asking for, [Success]
    Run the Sort Horizontal Points command on these points, 1 rail at a time, to recreate a rail string, [Success]
    Create CL from Rails, [No Success and my workflow is stalled here]
    Regress CL with Curve Diagrams
    Run Rails From CL

    I’m hoping this is enough work to b able to set out signals for the Signalling tool with ORD.
     
    Anyhow know why my workflow stalls on step 3? My rails are 16km long. Ive chopped them to 8km and it doesn’t work, then 4 km and still the ‘CL From Rails’ command doesn’t work. Simply hangs. The rails seems to have created correctly as I have profiles of each. I haven’t carried out Regression on the rails yet as I wan to do that to the CL once created, assume thats the correct order?

  • In OpenRail you don't have to import the rails as you must do in Rail Track. You can create the regression line directly from the rails linestrings.

    There is an issue with management of points when creating the centerline from rails:

  • ive just found this but video i have Release 2 installed and look different. im tryign to get Release 3 installed now so i can follow this more accurately.

    Whether its Release 2 or 3, i seem to be able to gain some Rails, even if it spoof survey points and rerun them, or use what i have. I cant pregress to gain my CL.

    Im also a little confused on the 2D/3D use. my Rails are 3D file but i ref them into the 2D file im going to create the CL in and the CL should be created on the 2D then auto create in the 3D Sub model?

    If i have points for rails, do i need to regress the atrign i gain before i produce a CL rom Rails?

    or, if i only have rail strings, is there any further regression analysis that needs to take place on the Rails before i use the CL from Rails tool?

  • the video shows the use of CSV file to import rail. I don't have any CSV file. I suppose there is not regular (BRT) method of importing rail using graphics. we got to have the csv file to bring in rail surveyed.
