Superelevation on Station Equation

KOMANG00429 — Wed, 05 Jun 2024 17:56:37 GMT

why the superelevation diagram that I made does not follow the station equation but follows the raw station. Is there a way for station superelevation to follow the station equation?

Hi @KOMANG00429, I hope you are doing well.

Why do you say it does not match? Could you please post screenshots to evaluate your situation?

I opened a few files I have with station equations and noticed the superelevation station labels are showing the correct station:

Station equation:

Label in superelevation view

In the previous images, you can see the station equation is at 5+000, and the label 5+013.091 delivers truthful information about the station. It agrees with the one I present in the third image.

Best regards!

Raw Station and Superelevation:

its work if i calculated first superelevation before add station equation (superelevation following the station equation), but when i add station equation first and then calculated the superelevation, the superelevation use the raw station to place critical superelevation station (not match with station equation). See image below

Station Equation:

Station after add equation:

Superelevation that calculated after adding station equation:

the ENC must be start at 10+014.56 (i use the csv import to set the station) but the ENC start at 10+024.56.

this my csv file to set the superelevation at that Curve:

Sorry for my bad english

Thank you @ecfernandez for trying to help me, really appreciate it

Best regards

Hi @KOMANG00429, thanks for posting again, and don't worry about your English. English is not my mother tongue either, it is Spanish.

About your problem, now I see it. It is because you are importing superelevation data from CSV. I advise you to do the following.

1. Explode your current superelevation view. You should have an ACAD block after that.

2. Erase your current superelevation data (the one you imported from CSV).

3. Select your alignment, go to the ribbon, and select "Calculate/Edit Superelevation." Follow the wizard and finish the process. Then, draw your superelevation view again.

4. Put your new superelevation diagram on top of the block of your superelevation view and trace it again, moving the grips you need to move, erasing the grips you need to erase, or even adjusting superelevation values that are not computed as your local policy demands.

I hope this helps. Best regards!

Thanks @ecfernandez , I'll try it later
