Forum Post: Making Sense Of My Curvature Diagram
Hello all It has been a while since I made a post, so here goes. I have collected some survey data of a rail alignment and imported this into BRT. I have created a curvature diagram so that i can see...

Hi All, While creating the turnout one message is pop up negative or zero arc length. I have verify all the data by drawing as well as hang calculations it is ok. What to do next kindly suggest. Thanks...

Hi Stewart, It looks like the accuracy of the imported points are poor (either rather poor track-geometry or something wrong in your workflow). Check if the x- and y-coordinates of your imported points...

Stewart In my humble opinion this is what you have (I'm not sure about the start - too little data). Two compound curves (large and smaller radius with intermediate transition) then reverse curve with...

No you didn't miss anything. This workflow is not possible anymore because you can't project points from a DTM to the cross sections. Cross sections are a true section of the 3D model. You found a...

Errors when ceating turnout is sometime due to geometry of the alignment on which you are placing the turnout. Rail Track does an analysis of the whole geometry and for some reason it can fail. With no...

Rail Track SS4 is released for a while now. You can use it but you must be aware that some workflows are not possible compared to SS2. The main interest is modelling capabilities. OpenRail Designer is...

Hi JPLN, Thank you for the prompt reply! Let me explain you in detail what I am trying to do; I am trying to put a cross over in straight track and track distance is 6.0m. The configuration of the...

LiPeng Thank you for your input this really helped. I did check if the decimal points had been imported and they did. Your recommendation about importing only the second/third point really help clear...

Hi Neville Thanks for your insight. I did manage to come up with the same solution but it was nice to know that someone lese agreed. What helped was removing some of the points which cleared up the...

Perhaps, here is a need for a clarification: If all survey points are measured exactly the same way, it's difficult to justify which points belong to "noise". The method reading fewer points does help...

I experienced the suggested workflow using ContextCapture Master to compute mesh from Points Cloud. The result was quite good. Situation with Rail Track SS4: you can't project points from DTM to cross...

Do you know When ORD (OpenRoads Designer) update 2 will be released?
View ArticleForum Post: RE: BRT SS4 & tunnel pointcloud
Thanks for that, an interesting exercise. I don't think my computer is up to the task of Context Capture, I understand that 32GB ram or more is needed, so I will ask a colleague to try it out and...

Do you set a negative value for the linear in the branch geometry ? I don't think it is allowed, that is why you get the message. What is the aim to set a negative value ? If I verify without any...

It should be soon, something like 2 or 3 weeks.

Great! How can we know when the new update is available?

View ArticleForum Post: DEGREE OF CURVE AND DELTA
As shown in the attached image, the delta is nothing but deflection angle of a curve. Then what is the degree of the curve?
View ArticleForum Post: RE: DEGREE OF CURVE AND DELTA
The degree of curve is basically the delta of a 100' chord (if using chord definition ... 100' arc otherwise).
