Hello, I have the horizontal alignment and vertical alignment created already, It is for a 30km road. Now due to the design changes, I have to modify the horizontal alignment in a certain area, please see the image below, we want to modify the horizontal alignment from the cyan color line to the red color lines (approx. 600m long).
What is the best way to get this done, redo the horizontal alignment and the vertical alignment, or we can edit the horizontal alignment without affecting the vertical alignment in the other areas? and of cause, the vertical alignment in the affected area needs to be adjusted.
Anybody please kindly share your expertise. Thanks in advance.
