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
I'm sure what I did here is really simplified compared to a real project. So I have to have a disclaimer that I haven't used this methodology in a real world project. I simply think about a modeling solution for a design. I often think of some 'out-of-the-box' modeling in ABD as a sculptor creates sculptures from marble, for example, and use the tools in that fashion.
Note that Family and Parts can be created for these components.
Thanks, Paul!
Hi Fraser,
I hope that the Wiki that Paul refers to below will help you to simplify the line string you are using to generate the rail.
Regarding your additional questions above - no, I cannot personally help with Open Rail since my focus is on AECOsim/Building products. I only mentioned it since Open Rail was designed for the purpose of modeling rail so could offer tools and functionality beyond what's available in AECOsim and/or MicroStation. I would do the same if one were to inquire about modeling a large piping system for a chemical plant (OpenPlant) or a complicated electrical raceway system (Bentley Cable and Raceway).
To some extent the same applies to your question about reducing the number vertices for an existing line string, mainly because modifying 2D linear elements isn't the type of thing that the building support team would normally handle. I do understand though that it can sometimes be difficult to know which Bentley team (or Community in this case) would be best suited to help. AECOsim, like most other Bentley "Power" products, includes the same set of base MicroStation functionality.
Regarding your last question, I am curious myself! Has anyone reading this thread ever modeling railway using AECOsim or plain MicroStation?
Another caveat, my background is building design, so not as familiar with rail type projects. Thanks!
