I need to modify the alignment of a road because of a intersection.
My problem is the profile, because I have to modify the alignment from start point (0+000) and the profile to the end point to remaine in the same place.
Now Civil 3d is keeping the profile fixed in start point of the alignment and I want to be in the end point. Can I do this?
reverse the alignment direction. add to it. then reverse the alignment direction again.
Good reason not to us 0+00 to start. A station equation would be a good way to go but you would have to be happy with some station back value.
Insert a point on the alignment at the pgl elevation. Pull station 0+00 to the new location and add whatever other edits are required. When you are done project the point to the profile view and autocad move your layout profile to the projected point.
