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.
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 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.
Is there any way to allow user input in an expression for a profile label?

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.

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 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.

View 1 Replies View RelatedThe 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.

When I open the expression variables available in a label style, I see different options available for different label styles.Can I combine expression variables from different label types? For example, say I want to make an expression that takes the Surface Elevation from a spot elevation label and subtract a variable from a pipe variable such as end invert elevation?
If you can do this, were can I find the expressions file on my computer or network? Can they just be dragged and dropped between label styles?
Now, in my understanding, the flow arrow should either be rotated 0, or 180 (pi radians). But clearly, some of them like to have their own mind about things, and decide on some other rotation. It seems that on the steep slopes, the arrows go a bit skew.
I think the skew is related to the actual elevation difference of the segment, rather than the steepness of the slope. A long segment with 15% slope has a worse skew than a short segment at over 30%, presumably because the elevation difference from the start to the end of the segment is larger.
Am I limited to the fields that appear on the label for a pipe network data band, or can I add my own customized expressions?
Using Building Design Suite Ultimate 2014
I'm trying to create a custom expression in a structure table that will list the "size" of the structure, wheter it be a circular or rectangular structure. My column simply states size and I want it to label 5' for a circular or 4'x4' for a rectangular (or whatever the specific sizes are). The thought was to create an IF function, but Structure Shape was not available to use in expressions (among other problems). Short of using the description field (tedious) as a workaround?
In this example - CB-104 is a rectangular structure and CB-106 is a circular. I'd like the CB-104 size to read 4'x4'.
Civil 3D 2014 SP1
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.
