How to model that??

[dpinho]

I am trying to model a Railway Turnout System, which has been modeled in SolidWorks.


I am attaching some pics so anyone can give me some tips


I'd be glad to send the IGES file of this part to help understanding.


The real trick part is the center part (nucleo). I have thought of doing some blend, or swept blend, I dont really know.


Any advice are welcome.


thnaks a lot

That looks like a fun project. You're asking a pretty broad question though. So I'm not sure this will be very helpful.

I would start by modeling the two primary rails at their full length and then adding and subtracting material where needed to created the intersection. I hope you are using a skeleton part or maybe even a master model merge. I wouldn't know how to do it without a solid top down approach.

If you're more of a Solidworks guy I would really avoid using assembly references. I've got a solidworks guy here and he always tries to use assembly references in ProE and it always makes a mess of things.

Sorry if this wasn't helpful.

Hi dpinho


It appears that this rail turnout was created as an assembly of approx 5? components in SW. The trick will be to follow this principle in ProE. I would strart by obtaining the seperate components from the SW assembly and re assembling the turnout as an assembly in proE. Then i would take the individual parts and work out how best to create them. the assembly appears to be symetrical about the centreline through the necleo component so it may be possible to model half of the assembly and mirror it to complet the task. Iam a little bust right now on and urgent orderfor a client, I will ten be travelling for about a week, however if you can get the individual part files from SW and the assembly send them to me at [email protected] and i can pick them up whilst travellingthen i cantry to take a look at the problem for you

Thanks for replying guys!!


fiebigc, I had same thing in mind when I started the assembly. First I did the rails, using simple sweep protusion. Piece of cake.butthenI got to nucleo andI just can

this is a hard and easy task, hard is the task want much more time , easy is the task is extrude, round and so on again and again.


you want to look for a simple method to complete the work .but don't waste time, start do it step by step ,this is the samplest method.


step 1 : model the whole ,


step 2 : detail the details ,for example ,round ,hole and so on

I'd use this advice. You can't go wrong with it.

thats a combination of many features. The rails I would create using sweeps probably. The other geometry should pattern easy enough....then hopefully get your rounds on there okay.

Makes it quite a bit more challenging when some other bloke modeled it first in another program... because your always going back to check how far off you are from the other geometry.
