Profile From file

[irakli.patsatsia93]

Hi guys,  

I'm trying to learn how to create a vertical alignment from a file.  

I created a .txt file and imported it into Civil 3D using the command "Profile from File," and then I attempted to add a radius between two points with the command ''free vertical curve'' (parabola and circular)  and, but it didn't work (see video).

Hi @irakli.patsatsia93, I could see from the video that when the software asked you to select the tangents, you selected the first tangent, and as it got highlighted I noticed how short it is. This is the reason why you cannot place that long curve you have. Any chance that you upload your file to check it?

Regards!

Yes, I understood that it was short (1500 radius cannot be in 20meter)  I tried the second method of creating a design profile, but I couldn't sort it into the correct format  .txt file.

Hi @irakli.patsatsia93, I took a look at your file and yeah! the short tangents are the problem. take a look a it

You have a series of successive tangents that I think they could be cleaned up. We might not need several PVIs in the middle of tangents with the same gradient. I would to something like the following:

I left the old profile behind the new one intentionally so you could see what I changed. That's why you still can see all the vertical tangent labels. However, take a look at the highlighted tangents (they are no longer short and can accommodate a long curve).

If you want your TXT file to produce a result like in the previous image, you must focus on providing the information for the beginning, end, and all the PVI and their curve length. You can check the following information: About the Format Requirements of Profile Files

I attached your file so you can take a look at what I did.

I hope this helps. Regards!
