Hello colleagues,At my company, I am trying to persuade the company's management to move from Autodesk to Bentley (and bring you more then 200 new licenses). Unfortunately, the new OpenRail Designer 2020 Release 2 gives me almost no trumps in my hand. After all, you made a copy of Autocad Civil from that great software (BRT). It's a huge pity. At the same time, you have eliminated perhaps the biggest advantage of BRT, namely Multiple Regression Analysis. The thing that designers in my area use every day and go to do almost miracles with it and even after more than two years, you are not able to implement it.
How would you create this easy (in BRT) example in OpenRail Designer? Please can you show me?1) I have two tangents and I want to place between them: Spiral (length 52m) - Circural (radius 480m) - Circural (radius 480m) - Spiral (length 52m). Lengths of Circulars are free..2) I have two fixed tangents and I want to place between them: Spiral (length 52m) - Circural (radius 480m) - Circural (free) - Spiral (length 52m). Lengths of Circulars are free..3) I have two fixed tangents and I want to place between them: Spiral (length 52m) - Circural (radius 480m) - Circural (radius 500m) - Circural (radius 480m) - Spiral (length 52m). Lengths of Circulars are free..4) I have two tangents (first fixed length) and I want to place between them: Spiral (length 52m) - Circural (radius 480m) - Spiral (length 40m) -Circural (radius 500m) - Spiral (length 52m). Lengths of Circulars are free..
1) 40 second work in BRT
2) Alternative solution

Hi Petr,
There is a tool in ORD - Geometry Connector.
It looks pretty much like Multiple Regression in BRT.
The only spiral type available there is Clothoid, but maybe it can work for you.

Hi, Petr!
My questions are almost not related whit your query. I'm curious, if you manage to create this compound curve, do you need to annotate it as a single curve?
And one other thing, do you need to annotate numbering on curves?
Because I trying lately to get into the program (ORD), and I was surprised that this options are removed.
(BRT V08.11.07.685, on MS, SS 2)
Hope this can help:
One thing that must be improved, post 2020-R2 (10.08.01.33) is the ability to select only part of the alignment. Actually second element is always the last of the alignment.
Enhancement request already logged.
It will also be enhanced to use regression points and should also include a nudge tool. Expected 2020-R3.
Hello Petr,
Just a comment regarding your post.
The "Regression Analysis" in InRail / RailTrack was the most unique piece of tool in all railway design software I know. It was a collaboration between Bentley (at the time Intergraph) and a series of European railway companies. I remember the visits from the development-teams when I was working for Danish State Railway (DSB). I'm convinced that was one of the reasons, the product was so widely used and appreciated among railway-designers in the world.
I think it's a real shame that this "tradition" - working closely with users/clients for development is down prioritized and for the ORD we only get what the Bentley developers think is best for us, but not what we really need/wished and how we are working everyday in our job.
Best regards,
LiPeng
The tool uses the spiral type selected in the Design File Settings, so it can work with any selected type, not restricted to Clothoid.
