AutoCAD Civil 3D :: Expression In Horizontal Geometry Point
Aug 9, 2013
I'd like to label profile elevations at horizontal geometry points. I accomplished this with a profile reference. Essentially labeling bottom of curb at pc, pt, mid, and pi, and would like to get and expression to add the top of curb, but under hor. geo style expressions you cannot pickup pgl data and PGL style expression are not loaded in the hgp data.

is there a way to set up the profile so it is anchored to horizontal geometry from certain point. that way when i change the alignment in the middle it won't cause profile to be shifted because station changes (length changed) while the vpi stations stay the same as before.
i can make a program in .net to specify a station and move all the vpi station by that amount which can be obtained easily by taking the length before you modify minus length after you modify.
Pretty common problem. it's not that hard to do in really the logic is defined. i have this alignment that's 60km long that's only one portion. hecka lots of horzontal curve and vertical curves. over 100.

I would like to build an expression that I can use in a label at a structure in a profile view to show the horizontal angle change on the alignment at the structure.
Of course, in the available structure expressions, we do not have the alignment delta angle at that point even though I have a referenced alignment in my pipe network.
Our subdivision code has minimum drop across manhole for different ranges of horizontal angle change.
I want to create a label that shows the minimum drop required at a manhole off it's referenced alignment and I would like to see it on the profile view, because that is where the drop value is relevant.

I'm using C3D 2012. I created a profile view for a straight horizontal alignment. The band label for the horizontal won't appear for this particular straight aligment. I have a few other alignments that has curves in it and the profile view displays the labels fine.
I tried to create a new straight alignment again, create a profile view but I get the same results.I also tried it on a new drawing using the NCS metric template with same results.
I can think of (if this is a bug) is to extend my alignment by say 0.1m and add a new IP at the correct alignment end, mask that on plan and end my profile view to the right length.

My profile style settings are great but my Horizontal Geometry Text is overlapping. I want to be able to drag the text to keep it legible. Simlar to PI and PB labels on the horizontal alignment.

I do know that tere is supposed to be an algorithm in C3D that will recognise when two geometry points are coincident on a profile view...that is, say a profile vertical geometry point happens to occur on a major station (for example).
I have never seen this actually work. When I have this situation, the labels stagger and I get two columns of identical data on my PV.
I know I can remove individual labels bY CTRL+select and eIther erase or turn visibility to false, but I would rather that C3D figured it out for me and removed the duplicate data.
Viideo link explains what I mean..

I am in the process of modifying our current company standards to conform to another set of standards. The main change is switching from "simplex" font style to "Tahoma".
Simple in theory but problematic in execution, our main alignment label style "GEO-LABL", used for P.O.T, PC, ect. utilizes an underlined reference text object in order to control the length of the line under the call. The base insertion places the call perpendicular to the alignment, when dragged to the left or right it switches to stacked text plan readable. Works like a champ with the "simplex" text style - 1.jpg see attached.
Now simply changing the font to "Tahoma" - 2.jpg the larger you make the text the larger the gap.I am trying to stay away from adding a line for the underline due to the difference in lengths needed when the call gets longer or shorter based on alignment name or stationing.

For composing a profile label, I can't find the option for Geometry Point Text, which would use our abbreviations under the drawing settings. It is available for alignments but not profiles. Currently have it text compenent being labeled with PVC and PVT, but I had typed that in.

Land desktop anchored the alignment stationing at the "+" sign directly on the alignment.
Is there a way to do the same in C3D 2010 without adjusting the x,y locations?

I am trying to create an expression in SAC and am having trouble getting it to work the way I want. The goal is to have the subassembly figure out what slope to use. If I do not have super elevation, I want it to use the grade for the in the input.output parameters. If I do have super elevation, I want it to use the super settings. So far I have this
IF((Side=Left)AND(SE.HasLeftSO),SE.LeftSO,CType(ShoulderSlope,Double))
This works if I am only creating a left side. However, I want it to decide which side super elevation settings by the input parameter side.

One of the main things I do is label elevations from an alignment and a profile, in plan view.
I have a style that does this, and it gets to the point where it asks to pick the profile.
If the profiles are data ref's, i can pick from a list, but if the alignment is xreffed, you must do a graphical pick.
This is super inconvenient, as my profile views are in a different base than my alignments, and they are way off to the side.
So I must xref the profile base in, and split my viws so I can pick them without excessive zooming.
Did Autodesk neglect the fact that if they make objects available via xref, they also need to make child objects available?
If I choose to use a dref as the data source, I must make a dref to the alignment and each profile I want available.
Three steps per street at a minimum.
This is also super inconvenient.
I'm struggling to find a decent workflow on this. Both approaches seem painful.
I had always thought the xreffed objects would provide the profiles, and only found they do not just now [URL]...

I'm trying to use an expression for text height and everytime I enter the name of the expression I get "Invalid Input". Is there a trick to doing this?
I even changed a style that "HAD" allowed me to use an expression, to a number then tried to reenter the same expression name that was there and get "Invalid Input".

I am trying to make a single point label style that will return a blank line in the label if no data is provided.
The way i have it coded now my label for a structure with only two inverts comes out looking like this:
STCB 500 Rim=300.00
12" CONC N IE=295.00
12" CONC S IE=296.00
IE=300.00
IE=300.00
I would like the number of lines returned to match the actual number of inverts in the structure and leave out the place holders.:
STCB 500 Rim=300.00
12" CONC N IE=295.00
12" CONC S IE=296.00
I can work around this by having a label style for each number of pipes, but i would also like this code to be inseted into a table style and in that case i don't know of any way to assign multiple styles to one table.
My current code looks like this:
RIM=<[Point Elevation(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
<[1 SIZE(CP)]> <[1 TYPE(CP)]> <[1 DIR(CP)]> <[IE TEXT(CP)]><[1 INV(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
<[2 SIZE(CP)]> <[2 TYPE(CP)]> <[2 DIR(CP)]> <[IE TEXT(CP)]><[2 INV(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
<[3 SIZE(CP)]> <[3 TYPE(CP)]> <[3 DIR(CP)]> <[IE TEXT(CP)]><[3 INV(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
<[4 SIZE(CP)]> <[4 TYPE(CP)]> <[4 DIR(CP)]> <[IE TEXT(CP)]><[4 INV(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
LADDER <[LADDER(CP)]>
The problem is that 1 INV-4 INV are being defined by an expression that reads like
{Point Elevation}-{1 MD}
so when no data is intered for my UDP "1 MD" it returns the point elevation. I want an equation that says if rpoitn elevation -measure down=point elevation then no data is shown.

I am trying to create a label for fire hydrants in plan view that shows the flange elevation. I want the elevation to be 0.4' above the adjacent road profile. I added a reference text component to my label style that shows the profile elevation. Where would I find the expression for the profile elevation reference text?

Here is my expression:
IF((FMOD({Raw Station}+5,15))!=0,-1,({Profile Elevation}-100*FLOOR({Profile Elevation}/100)))
I have also tried it without a pair of brackets:
IF((FMOD({Raw Station}+5,15))!=0,-1,{Profile Elevation}-100*FLOOR({Profile Elevation}/100))
and I have tried it using {Station Value} instead of {Raw Station}
Here's what it's meant to do (because it's a long one):
If the station value + 5 is not divisible by 15, return -1
If the station value + 5 is divisible by 15, return the profile elevation,
if the profile elevation is in the 100 range, subtract 100
if the profile elevation is in the 200 range, subtract 200...etc
Here is my conundrum: If I use the expression in a profile label, it works fine. But if I use it in an alignment label as reference text, it returns -1 for every value.

I was wondering if it is possible to use an expression in a general note label? The type of label I am using is a general note label that displays our finish grade profile elevation in plan view. What I am trying to do is add a value to that label for the TC elevation and G at the ROW. I noticed in the settings tab of the tool space, surfaces has an expression button that has what I want but I am not seeing that under General/Label Styels/Note. Is it possible to right my own expression? We are using Civil 3D 2008 with Windows XP.

I'm trying to build an expression to display the Middle Ordinate for profile curves. I don't usually do this but it's required for this project.
The first thought was to subtract the PVI elevation from the profile elevation. The PVI elevation is easy but I don't see an easy way to get the profile elevation. I can go through the whole formula for calculating the grade. But that will probably take some debugging.

I am looking for a Line Label Style Expression which will perform a rounding function on distance labels that display my "General Segment Length" value.
What I need is to be able to remove "Trailing Zeros" from my distance values, so that if precision is set to say 0.01 and my distance value is measured as 45.5, I do not get 45.50 but 45.5.
I need this to round for:
1 decimal place
2 decimal places and
3 decimal places

The neww line expressions for Grid distance are phenominal. My problem is getting them into curves. All I want to do is apply the grid scale factor to the curve length and radius, but I can't narrow down the parameter. The Drawing Scale conversion links to the annotation scale. I've also noticed people just scripting in the value, but that doesn't work when the majority of the office doesn't operate at that level.
Also, I work in grid and need to convert to ground. I noticed that the system only does ground to grid, so I'm inputting an inverted scale factor to get the results in need in my distances.
