AutoCAD Civil 3D :: Adding A Curve To Existing Alignment
Jan 4, 2009
I have an existing alignment issued to me which has been created using all straight lines even where there should be curves. I am trying to insert curves in these areas. Using free curves (2 entities and a through point) I create a curve then somethings happen I can't work out -
1. The curve is created but the original straight linework stays. I would have thought the original linework would automatically delete. See attached pdf between points 60 and 62 the curve and straights can be seen.
2. Then all stations after the curve are changed to the question mark symbol. If i click on the alignment all the grips are still there for the full length of the alignment, indicating the alignment is still in one piece.
3. If I try to create another curve further along the alignment it won't allow it. Stating on the command line "Selected entity must be part of the main entity."
I was wondering if it is at all possible to add a polyline to an existing alignment? The purpose of doing so would be to extend the alignment so that I can display the proposed kerb and gutter.
I have one surface "EG" and two alignments, I'll call 1 and 2. The profile view already has the alignment 1 surface projected on it. I go to profile>Create Surface Profile and select alignment 2, Surface EG, go to ADD it but the profile list is empty. Shouldn't it already be populated with alignment 1 and all I'm doing is adding 2 to it? Both alignments are in the same site.
In LDT listing curve data was as easy as selecting an alignment, clicking edit and printing out a spreadsheet with all the required info. how to do this in C3D. Inifo I need:
I am setting up a template for my company and have noticed that I can't change the line/curve/spiral LTscale:
I have chosen a layer with the CENTER linetype for my line/curve/spiral in the style editor. The Alignment appears correctly with the CENTER linetype. However I want to make the dashes a bit bigger, so I change the LTscale in the style editor to 4, but then nothing changes.
When I change the same setting for the "line_extensions" element to the same layer, these WILL update when changing the LTscale.
All my LTSCALE, PSLTSCALE, MSLTSCALE are set to 1.
All other lines, such as polylines and featurelines, as well as the line extension lines of the alignment update correctly. Its just the alignment line.curve/spiral elements that do not.......
Are these locked somewhere?

Is there a way to move the station on an existing alignment? For example, I have an alignment created and want to move station 10+00 so it represents a different point on my alignemnt.
A trick to make automatic a dimension line for the distance between the existing alignment of a road and the design alignment.
This dimension line I want to be in the cross sections. I make a project with a widening road and I have to show the difference between the old and the new alignment.
I am working on a corridor. I have a proposal profile, and now i wanted to add a vertial curve between the new profile and exsiting. (see attached.) but i have not done before.
I'm trying to create a surface using feature lines. I have an alignment and profile that I have created a dynamic feature line. However, on a horizontal curve, it apparently creates a vertex at the start and beginning of the curve, and nothing on the curve, so it triangulates between those two points and that's it.
Do I need to play with spiral tessellation (0.25), mid-ordinate distance (0.1) to get some points along the curve?
How the deflection angle can be shown in the horizontal alignment curve? I’m wondering if there is a way to automatically show the deflection angle of the horizontal alignment curve (attached)?
You are able you get range of properties, i.e length, chord length, start/end chainages, mid-ordinate.
I've notice lets for arguement sake 'chord length' text component editor is: <[Chord Length(Um|P3|RN|AP|GC|UN|Sn|OF)]> but is it possible to modify the code so i can insert half a chord length.
Ive tried
<[Chord Length(Um|P3|RN|AP|GC|UN|Sn|OF)]>/2 ---- doesn't work
<[Chord Length(Um|P3|RN|AP|GC|UN|Sn|OF)]/2> ---- doesn't work
<[Chord Length(Um|P3|RN|AP|GC|UN|Sn|OF)/2]> ---- doesn't work
<[1/2*Chord Length(Um|P3|RN|AP|GC|UN|Sn|OF)]> ---- doesn't work
In this moment I am trying to add to my profile line a PVI -which I know how to do it- with the capability of modify the criteria for the vertical curve. In this moment every time that I add a PVI the tangents do not have a vertical curve and if I open the Panorama Profile Grade View Window it does not allow me to change either the length or radius so their values in these cells are empty.
How is possible then to edit -create- the vertical curve for a PVI that was not created in the first shoot?
Is there a way in C3D to add elevation information from a profile to an alignment label? What I'm trying to do is add labels to an alignment in a plan view with elevation information from a profile design associated with that alignment at a particular station. For example, the note would read:
ALIGNMENT B STA: 12+83.67 ELEV: 435.87
I can't figure out how to add any elevation data to the alignment note. I really don't want to have to create a section and a corridor surface, but that's the only way I can think of right now... and I'm not sure that would actually let me add a station and elevation in the same note in a plan view.
I am using AutoCAD Civil 3D 2013. I am thinking that this may not be possible at this point but I am still going to try. I have an alignment label style for station and offset. I also have created a dynamic block for the border of this label to put around that label. This call out border is not a typical single width border so the borders within the alignment style do not match and cannot be used for our designs. I have attached an image of the border around the label style for a random alignment. So far the dynamic block has been a great fix for the border so that we dont spend a lot of time drawing in these borders for each label, but I was trying to add this dynamic block to the label style so that it would act as the border.
So far I have tried adding the block as a component in the layout tab of the label style but it appears where I anchor it and does not access any of the dynamic attributes to make the callout box larger in reference to the text. I know I can insert it so that in general it will be surrounding the Station, Offset, and Alignment contents, however, we frequently add additional text to our labels to callout pipe bends and other items so the box is not typically the same size.
How I might be able to do this or if it is not possible at this time?
I have an existing ground surface with all different z co-ords and im trying to add three proposed buildings to my exisiting ground with all the builidngs having a level of 32.5 as a minimum, however at some points the ground is higher than 32.5 and I only want to raise my existing ground to 32.5 within the proposed buidling layout if it is below 32.5 as im doing a flood calculation. What do i need to for this?
I am in the process of creating the cross section sheets and including them to an existing sheet set manager. When I try to create them I get an error saying "Sheet Set not created" which is odd because I selected add to existing ssm. If I save and exit out of the drawing and then get back into it, the sheets are created correctly in my layout tabs, but aren't added to my ssm.
How can you add the chord bearing, chord length, and tangent to an alignment table with the curve data in it? I have the length and direction but cannot figure out why the others will not load and update in the chart. I am using Autocad Civil 3D 2012

I think it is normal to want a style showing stationing, speed design stattions, etc.But.... Radii of curves ? Clothoid parameters ?
Why is the reason Autodesk developers think that designers dont want to see this information instead of "add labels, aligments, multiple segments,. etc ....
I have 3 profiles that I've superimposed together. Then I created sheets using the superimposed profile. I used the wizard and had Civil 3d do it for me (2012). Now I have to add a 4th profile to the mix and get it to show in my profile views that have already been cut. The data is shortcut into the drawing with my cut profiles views. How do I get it to be in the cut profile views without re cutting everything?
I using a data reference/shortcut to properly label an alignment in paperspace. However when I reference the alignment in and apply the labels the aren't the same as the original alignment that I am referencing. Is there a setting where I am supposed to apply a new beginning station.
Also it seems as though the stationing(distance) isn't even matching up 1:1 with the original drawing. For example in the original base drawing my alignment starts at 10+00 with the next PI at 14+76.98, but the stationing on the reference alignment starts at 0+83.33 with the very same PI being labeled as 1+23.08. So the very same distance is 476.98' in the real design and the drawing it's being referenced in, but the stationing of the referenced alignment shows it as 39.75 Units.
I've attached a screen of the beginning of the alignment.

Using Civil 3d2012, Is it possible to change the alignment label style set after the alignment has been created? For example, for an alignment that was created with alignment label set X - change the label set to alignment label set Y? It seems like this should be pretty easy, I must be missing something obvious.
I have a question on Alignment PI's. (Point of Inflection/Intersection)I have an alignment where some PI's have curves, others are merely hard bends.
Is there a way to automatically label the PI's even if they have an associated curve? (I'd like PI, PC and PT)Alternatively, can I only show markers at PI's without curves?
I’m wondering if there is a way to launch alignment grid view/alignment entities (attached) without the need to first launching “alignment”? This dialogue box is quite essential in editing the values of radius, degree of curvature and deflection angle for the selected curve.
Can I inherit the station from one alignment as the begin station for another alignment?
For example. Alignment 1 is 1000 ft long and starts at sta 0+00.
At sta 8+01, Alignment 2 begins and goes off in another direction.
I manually enter 8+01 for begin station Alignment 2. Life is good. Still in the design stage, and customer needs to modify Alignment 1 to avoid something. Now Alignment 2 intersects Alignment 1 at sta 8+15, but same N/E coordinates.
I manually enter 8+15 for begin station Alignment 2.
It would be better if Alignment 2 could inherit the begin station based on the new stationing from Alignment 1.
