Hello, is there any node similar to PVIandRadius or do you have maybe the Python code to use it momentarily civil 3d 2025?
@zachri.jensen and @hosneyalaa Please could you help me with this?
I’m not trying this before
Try AddFreeCircularCurveByPVIAndRadius Method by python code
https://help.autodesk.com/view/CIV3D/2025/ENU/?guid=fee99593-3c87-5093-dec2-464e116b603f
Can anyone help with the code in CPython?

I can’t get it to work

I have tried but it still does not work
I find it incredible that with the number of experts on this forum, no one is able to give you an answer. Great work, I’m trying to fix the error, but I can’t seem to…

@manuel.lozanomASTWU could you fix it for civil 2025, I tried with the code you left but it doesn’t work.
I use this code for multiple profiles at my regular job, in version 2025.1. I just wanted to show you the way
Example (1).dyn (25.1 KB)
Maybe it’s my mistake but in civil 2025 the code does not work.
The file I am using as a test is the same as the one I attached in my previous posts
Sorry a
I’m not a expert. It’s civil 3d 2025 but with my code in your dwg… just wanted to show you the way
