The workflow that I use projects a point into the profile view and is selected as the new road design is constructed. Yes the point and label are dynamic to the profile.
1. Create a corridor for the primary road.
2. Build a surface from the corridor.
3. Create a Random Point using Create Points toolbar.
Select the corridor surface as prompted. Point is placed marking the main road elevation at the intersection point.
4. Locate Profile View in the home ribbon and select Project Objects to Profile View.
5. Select the point when prompted, enter
6. Select profile view to label.
The label projected is dynamic and a custom style should be created. Change the primary road design, rebuild the corridor, and make sure the surface is up-to-date. Now select all points, right click and select Elevations from Surface. This is located in the right click menu and in the ribbon. All labels are updated, simply select the grip and drag it to the new elev.

very nice trick...
ReplyDeletebut I'm new to civil3d and my geometry is complex a little, dont know how to create corridors...would it be possible to project a point that is on the main road profile?
I would like to be able to use a profile to set point elevations and not the surface. the reason is my profiles are modeling top of curb and not CL and our street to street connections are made at the CPI's (curb point of intersection) of the curbs which are 0.5 feet above the surface. Also the points from surface are only as accurate as your surface where from a profile they never vary. We have had issues with points or labels from surface when you are in curves, cul-de-sacs, knuckles and intersections.
