Modelling Railway Track

Hello,

I have 3D linestrings representing the running edges of a railway line.

I would like to turn them into 3D rails.

BUT My linestrings have too many vertices - I would like to reduce to about a third the number of vertices.

AND extruding the rail profile along the linestrings takes for ever and makes the file unmanageable (solid by extrusion)

Can anybody help me  ?

Three things :

Reducing vertices in linestring.

Modeling rails - is extrusion the correct way to go ?

General advice about modelling railway track.

Thanks

  • Hi Steve,

    Thanks for the reply.

    Steve, please do not be offfended, but I have to tell it like it is.

    I have been using Microstation for over 25 years and I am educated to university degree level.

    Because I work in isolation, it is virtually impossible for me to learn anything new in Microstation or AECOsim, never mind learning a whole new

    program.

    So can you describe to me how I would use Open Rail to model railway tracks never having used Open rail before ?

    Or let's try something simpler : Describe to me how I can find instructions to reduce the number of nodes in a linestring ? Which to me seems a fairly reasonable request.

    Don't tell me how to do it ! Tell me how to find instructions how to do it. Bet you can't.

    All the best,

    Fraser
