AutoCAD Civil 3D :: Create Polyline From Figure Using BaseCurve Method

Nov 18, 2013


You said that there is no need to flatten, but each method I have tried does not produce a polyline with curves.

I tried:


If if manually flatten the figure using a dummy suface with the AeccFeatureElevsFromSurf command, the polyline derived from survfig.BaseCurve will then have actual arc segments.

Is there another method or a way to flatten the figure programatically first?

AutoCAD Civil 3D :: Assign Mline To A Figure Style In Figure Prefix Database

Oct 29, 2013

I am using AutoCAD Civil 3D 2011.  I am wondering if there is a way to assign an mline to a figure style in the Figure Prefix Database.  Ultimately I am trying to create storm drains that have a width automatically (ex. 12" SD would come in at 12").  Right now I have a single center line that comes in and I manually offset the line to create a width or I place an mline over the center line.

AutoCAD Civil 3D :: Create Figure Prefix Form Excel Spreadsheet / Access

Apr 19, 2012

Is there a faster way to create figure prefix i.e form excel spreadsheet or access.

I have one tip also. When you modify the figure database "C:ProgramDataAutodeskC3D 2013enuSurvey" by using notepad and you add "*" after each figure it will connect during linework codes that much the prefix code and will exclude the integer, EPN1 and EPN2 will be treated as EPN

The aterisks can not be added from the civil3d .

I used it to clear out the old vertex information, and then add new vertex points.All works on the screen until you use the undo command then all the vertex points are lost. Just created new polylines and deleted the old to fix it. Not ideal as I was storing the ObjectId’s in Xrecords, which now have to be updated with the new id’s

AutoCad :: Best Method For Creating 2D Polyline For NC Routing From 3D Solid?

May 2, 2012

I have discovered a 3D polyline cant be joined to a 2D polyline and when i exploded 3Dpline then flattened it ,as recommended elsewhere on this forum,it seems its shrunk in length.The NC router I have access to has to use 2D polyline for the path of the cutter.wish i could simply fed the 3D object into the NC router software and that was all i had to do.

AutoCAD Civil 3D :: Create Ployline From 2D Polyline With Curves?

May 3, 2011

I want to create a 3d ployline from a 2d polyline with curves. When I use the convert 2d polyline to 3d polyline command it places a bunch of vertices along the curve so when I go to place elevations on the vertices it takes too long. I want to be able to give an elevation at the pc and pt and have it place elevations along the curve from this info like it does on the stright lines.

AutoCAD Civil 3D :: How To Create New Vertex Points In Line And 3D Polyline

Nov 24, 2013

I want to create new vertex points in feature line  and 3dpol.

I have this:
if (obj.GetType() == typeof(Autodesk.AutoCAD.DatabaseServices.Polyline3d)) {
Polyline3d p3d = (Polyline3d)trans.GetObject(entRes.ObjectId, OpenMode.ForWrite);


In this code line:

oFtrLn.InsertFeaturePoint(punt, AeccLandFeatureLinePointType.aeccLandFeatureLinePointPI);
always catches the same Exception "the value is not within the expected range" .I have translated it because I get "El valor no está dentro del intervalo esperado". Perhaps is this: " Value does not fall within the expected range.".

I have tried it with different point3d values but always catches  Exception.

With pol3d I have similar problem.

AutoCAD Civil 3D :: Using IntersectWith On Figure And Alignment?

Feb 27, 2013

I need getting the crossing point for a survey figure relative to an alignment. I'm trying to use the IntersectWith on my active alignment. I'm able to see my figure in debug mode so, I think I've got access to each survey figure. I think I need to cast the figure as a com object to a acad entity using directcast, but that's where it's going bad. When using the ofigure.GetObjectId it returns an integer value and it fails in VS Express 2010 in the DirectCast when trying to pass the objectId.

The error (if I'm setting this up correctly) :integer cannot be converted to objectid
'Get figure crossing point Dim ofigures As AeccSurveyFigures = oSurveyProject.Figures 'Dim figEnt As Autodesk.AutoCAD.DatabaseServices.Entity Dim intPoint As New Point3dCollection() For i = 1 To ofigures.Count - 1 Dim ofigure As AeccSurveyFigure = ofigures.Item(i) Dim figObjectId = ofigure.GetObjectId Dim figEntity As Autodesk.AECC.Interop.Survey.AeccSurveyFigure = DirectCast(m_trans.GetObject(figObjectId, OpenMode.ForRead), Autodesk.AutoCAD.DatabaseServices.Entity) m_alignment.IntersectWith(figEntity, Intersect.OnBothOperands, intPoint, IntPtr.Zero, IntPtr.Zero) Next

AutoCAD Civil 3D :: Survey Figure With Bad Elevations?

Jun 29, 2012

I have a survey figure that no matter what will not come in with the correct elevations, its a spline (continous) curve that the elevations get blow up on.

Only thing I can think of is the when it starts to interpolate the curve it cant get the elevations correct, this only happens in the curved area, once it goes tangent everything goes back to normal.

AutoCAD Civil 3D :: Figure Prefix Database

Aug 25, 2013

I am trying to work on my figure database and have run into an issue I don't understand. Curious as to weather or not it's something I am doing, or just a bug.

I wanted to look at every possible line that could be imported so I created a dummy point file using the Figure prefix data base and imported it into one of my blank templates and ran into to curious issues.

Issue 1

CP is connecting to AA

Issue 2

OC only connects if the point has an identifier behind the OC, for example OC01.

Here is a copy of the figure database and point file I am using. I understand you will not have my layers, but the connectivity should be the same. Let me know if you need anything else.

Any way I can align a new polyline to a reference polyline (orig polyline).

The 2 polys will be generally the same length, however, the number of vertices will differ.

Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.

AutoCAD Civil 3D :: Project Survey Figure To Profile

If I try it again, the command tells me that an object already exists in the profile and will update it. What am I doing wrong?  What is the correct procedure to project these lines to a profile?

AutoCAD Civil 3D :: How To Figure Multiple Volumes From Two Surfaces

Sep 26, 2013

using CIvil3D to figure volumes.  I have a very large aerial topo from a couple years ago to compare against a topographical survey I completed this year.  No problem creating surfaces. 

Question:  In the topo's, I need to get a volume from two different area being a fill area, the other being the borrow area.  Don't want any volume data throughout the rest of the site.

Do I just create one large surface for each topo and designate boundaries somehow?  Or do I need to create multiple surfaces for each topo?  If this is the case, will I need to make sure any breaklines, etc. don't cross from one area to the other?

AutoCAD Civil 3D :: Figure / Feature Line Styles

May 29, 2012

Why are figure line styles and feature line styles not shared, or a parent / child relationship?  Also, should match properties change the style of a feature line to appear to be the same style as the figure line?  The style only exists in as a figure line style. 

If we offset a Figure line (feature line stepped offset) we get feature line, then we match properties to a figure line that has the correct style.  The prospector says the Feature line has the style of the figure line; however, if we edit the feature line properties the style is set to none.

AutoCAD Civil 3D :: Created Project - No Access To The Figure Properties

Mar 7, 2013

Recently I upgraded to 2013 and I been having some issues with my survey DB, first of all I created a base data shortcuts project template folder with all my folders and a default Survey DB.

once I create my project, and import points to the default DB, I have no access to the Figure Properties. Is this feature, that worked in 11 & 12 now broken in 13? I have gone into the setting and copied a new files to the folder several times, to no avail, and there are no other versions of C3D on this machine.

So now that I have my points in the drawing, I go to translate them to my survey, generally I will utilize line in the drawing between field data, and platted data to translate and rotate to the platted lot or lots and the work from there on any calcs or changes. However, when my OSNAP toolbar is docked and locked and I go to select a point line the midpoint, I have no access to the OSNAPS. This also, worked in 11 & 12, but seems broken in 13.

AutoCAD Civil 3D :: Figure Prefix Database And Break Lines

Aug 26, 2013

I am running Autocad Civil 3D 2012. I created a figure prefix database that our surveyors were familiar when coding in the field. It is a numeric code list. I received a survey last week that had 6 break lines coded in the point file. Only one of the 6 acts as a break line.

All break lines start and stop with the right line work commands but they fail to break crossing triangle legs. I've checked everything I can think of and the setup looks correct . The only difference between the one break line that works and the others is that break line has sequential point numbers while the other break line codes are scattered throughout the point file.

AutoCAD Civil 3D :: Matching Letters In Figure Prefix And Description Key Set

I have Figure prefix of GPNT for painted gas line and GP desciption key for Guy Pole. Imported survey text file, linework for GPNT came in correctly but at each shot the symbol for GP (Guy Pole) came in. Is there a way to fix that without creating a description key for GPNT. Have others with the same situation. Wanted to avoid adding description keys for items that were displayed all the same.

AutoCAD Civil 3D :: Convert Figure To Feature Line - Export Survey Figures To Genio?

Sep 12, 2013

I have a client who uses Bently MX Roads for road design and requires that survey data be supplied in GENIO format. I realise that there are many possible options to get Civil3D survey data into MX, but I am trying to explore the use of the Subscription Extension to Import/Export GENIO.

Surfaces - no problem. Points - I see how I can get that to work. But the only linework that can be exported is Feature Lines, and it is also important that the feature lines have a name (likely related to the layer it is on).

I can convert survey figures to feature lines and name them one by one but would be very time consuming for a whole survey. Is there any way of doing all figures at once?

I'm guessing not and that it is probably easier to do the Genio creation from dwg in MX itself.

AutoCAD Inventor :: Templates Not Used Depending On Method Used To Create New Part File?

I have found that if I use the drop-down to select a new part file, it does not use the default (and only) part template in my templates folder.  I know this as there are several settings that do not match.  If I click on the icon to open the new part dialog, it displays my templates (part, assy & drw) and creates the new file based on those accordingly.

Any setting that needs to be changed to correct this behavior?

AutoCAD Civil 3D :: SSA Rational Method

Sep 20, 2013

SSA rational method. I have to compare results of rational method between SSA and another product. Plain rational method, steady flow, Darcy-Weisbach. Times of concentration (TOC) are manually defined.
I played a bit with the units, formulas, IDF curve is defined as pair of values time/intensity. Seems that I achieved something. Results are more or less similar, but there are some differences. After playing with both programs, comparing in Excel, think that I found what is different.
So, I have very simple example, of one channel with catchment areas. All areas have the same runoff coefficient – 0.8. Pipe diameters are constant (500). The whole analysis is restricted between 5 and 10 minutes of rain duration (5 min-397.22 l/s/ha and 10 min – 321.53 l/s/ha). I converted IDF to mm/hr. So I have the next example:
[picture in attachment]
In theory, what I learned about rational method, there is next definition:

Intensity from IDF curve is defined by TOC. TOC is defined by sum of „entrance time“ (which is defined by shape and size of catchment area) and sum of upstream flow times. In my example I defined 5 min for every area.

So, for example for pipe nr. 3, TOC is calculated:
TOC_3 = Entrance time for area 3 + Tflow_1 + Tflow_2 + Tflow_3
For example:
TOC_3 = 5 min + 0.67 + 0.45 + 0.51 = 6.63 min
That TOC_3 (6.63 min) is base for reading appropriate value of intensity (I_3) from IDF curve. The flow in pipe 3 is then calculated:
Q_3 = I_3 * (A1 * k1 + A2 * k2 + A3 * k3)
This is the way how I learned rational method. But results between SSA and another product (which works in a way explained above) are different. Differences increase downstream.
After playing with results in Excel, I found out that SSA does not summarize in TOC all flow times upstream. So TOC in SSA is calculated simply by initial entrance time and flow time in specific pipe:
TOC_3 = Entrance time for section 3 + T_flow_3
So, there is no time added from T_flow of pipes 1 and 2. Seems that it is major difference which leads to final results differences. I tried to understand all options of SSA to find possibility to add upstream flow times, but without success.
