Showing Profile Elevation Differences Right above Profile 2

Hello!



I am a new user of AutoCAD Civil 3D 2012 and I have a problem when creating profiles with it for my company.

 

The profile requirement in my country is that the differences in elevations of points along Profile 2 (the proposed new road elevation) and Profile 1 (the existing elevation/surface) should be computed and shown right above the Profile 2 line. For example, if at a certain point PT 1 the elevation of the proposed road is 132.44 meters and the elevation of the existing surface is 132.45 meters, the difference is -0.01 meters and it should be shown exactly above the Profile 2 line (or a little bit above it) but not on it. The same should be done for every chosen point along the proposed profile.

 

So far, I have done this manually, by dragging the difference (already automatically computed and shown in one of the bands below the profiles) to the correct place for every single point. However, I don't know how to do this automatically, and none of my colleagues knows either. Can you give me any ideas how this can be done automatically?

 

Thank you in advance for your attention and attempts to help me!

Some images showing what you get and what you want would be useful:smileyhappy:

I assume your differences are in a band all by themselves?  In this case, just change the band's gap setting so that it gets placed where you need.

Neil,

 

Please, see the attached .PNG picture. I just want to mention that I did not properly explain to you the problem (and I do really apologize for that!!). The elevation difference data should be above the Profile 2 line ONLY IF the difference is positive (i.e. the newly proposed road is in a fill section). If the difference is negative (i.e. the newly proposed road is in a cut section), the elevation difference data should be right below the Profile 2 line. This is visually shown in the attached picture. I want to assure you that the picture correctly shows what I do have on my profiles now and what I want to get. If you have any additional questions, please, do not hesitate to ask me. Once again, thank you very much for your help!

Mike,

 

The problem is not in the band itself. Please, see the .PNG picture (attached to my second post) to see what profile I have right now and what I want to get.

The picture is a big help in explaining what you want to achieve and it makes a bit more sense now. I'm not too familiar with modifying the profiles as the UKIE templates that I use are fine for my purposes.

 

Hopefully someone with a bit more knowledge in this area can assist.....

Hi, I understand your problem as it's a standard we follow in Greece too.

 

I don't have a "proper" solution to this, but I figured out a wayaround which I use in the very end of a longitudinal section production. It will sound a bit "anorthodox" but it's better than nothing... or click click clickinggggggg

 

surface1 is the base surface, upon which you run an alignment and a profile "FG"

create a feature line from this alignment giving to it the elevations of the FG profile when asked

create a stepped offset of this feature line (the distance doesn't matter) and an elevation difference of 0 (same elevations)

create a surface "2" from these 2 featurelines (import them as breaklines)

at this point you may check (create profile from surface into the alignment) that the surface2 has the exactly same elevations with your FG profile by importing it in the profile view you are already viewing

(make these checks please... I wouldn't want to cause you any trouble)

 go to analyse - volume dashboard (version2013) and create New Volume Surface

style: none

base: surface 1

comparison: srface2 and OK

surface 3 is created which comes out of this Surface2 (or else words your alignment and profile) minus Surface1

 

create surface from profile and add Surface 3 to your alilgnment

Profile view properties - elevations tab - automatic (the numbers should be around zero, negative and positive perhaps)

 

in the new profile displayed in your profile view assign labels to the profile (right click - edit labels) and assign a style showing the elevations along the profile's line

for checking purposes insert a band showing the elevation difference of FG - Surface1 at the same stations 

 

we're almost there...

if the numbers are identical we have no problem up to this point

 

now go to your FG and assign a label with a reference text, referencing the surface3 profile elevation

at this point you ll get ??? instead of numbers

isolate the labels, ctrl & cross window from left to right to choose only the labels, and in the properties window assign Surface3 in the Reference Text Object value

the elevation differences will all fall either up or down the profile line (depends on the style settings) you used,

but since you 're in isolation mode you can choose either the positive or the negative numbers and flip them.

 

do not erase the surface3 at any time or you will lose the data

better yet explode the labels for a more static situation.

 

hope I helped - good luck
