AutoCAD Civil 3D :: Widths Of New Sample Lines
Dec 22, 2013
how to create a new sample line group and a new sample lines within that slg: URL....I have checked what is the default sample lines width (create sample lines command):
Autodesk.Civil.Settings.SettingsCmdCreateSampleLines SobreanchosSamples = default(Autodesk.Civil.Settings.SettingsCmdCreateSampleLines); SobreanchosSamples = civilDoc.Settings.GetSettings<Autodesk.Civil.Settings.SettingsCmdCreateSampleLines>(); Settings Cmd Create SampleLines SettingsCmdSwathWidths anchos = SobreanchosSamples.SwathWidths; double anchoIzquierda = Convert.ToDouble(anchos.LeftSwathWidth); double anchoDerecha = Convert.ToDouble(anchos.RightSwathWidth);
But how can I put these values (left width and right width) for a new sample line?Sample line class doesn't have "left width" or "right width" property ¿? Do I have to create a new vertex? However I think that I can´t add new vertex in vertex collection.

I'm trying to create sample lines at sta. 0+58, 1+08, 1+58, 2+08......................
My alignment begins at 0+00.
In the Create Sample Lines - By Station Range I set the From Alignment Start?end both to false and set the start and end stations as 0+58 and 20+58 respectively. The 0+58 sample line plots at 0+58 but the rest of the sample lines plot at even 50' stations (1+00, 1+50...).

How or if you can add sample lines to a specified group? I created a group only to realize that there are some specific stations I need. I do not want to re-create the group and re-assign the materials nor reproduce my volume reports. I just want the section plotted on my sheets.

I have my surface, aligment and sample lines created, but I cant get my sample lines profiles.
The grid apperas without data, it is like I have never selected a surface, but I did !
This is what I get , totally empty

Why the sample lines don’t appear on the prospector?
I’m wondering why the sample lines don’t appear on the prospector like other components such that we can have an access to delete them, for example.
How can I get a list for all the sample lines?

Can we automatically add sample lines at vertical curve points (e.g. BC, EC, Bottom of curve) ?I need to show the sections at these vertical curve key points.
I am using C3D 2011 but could not find that option when creating sample lines in a station range.

Im trying to place sample lines along a very sinuous alignment and about a third of the way down all of a sudden the little tracking marker jumps to what seems like thousands of kilometers away and starts tracking along some invisible alignment which does not exist?
I have tried everything I can think of from every type of sample line creation option to recreating the alignment and auditing the drawing. Nothing I do creates different results. Is this an alignment issue and being cause by all the tight bends?

I need to create points with surface elevations along sample lines. The points need to represent the verticies one would see in the section editor. I've attached an image of my section editor for one of my sample lines. I need to create points that represent these 24 verticies along this sample line and do so for the rest of my sample lines as well. Is there an automated process to create these points?

I wanna interpolate points from surface but only in that area where my sample lines intersecting with the surface. There is a point creation tool that makes this based on polylines but I have to many data and it will get to much time to do this. So, for better understanding I attached some pictures, in the first picture it is shown the final result which I have made based on polylines, but here is also a problem, the tool is not putting points where the surface is changing ( on my second picture I highlighted with red circles).

I created sample lines and section views for my road projects. I set all line works to appropriate layers except for "Segment and Points". Cannot change from layer "0".
I right click the existing grade on my section views, click "edit section style", click "display", then change the layer of Segments and points and click "OK", "apply".
Go back to my drawing, verify the layer but still layer "0". I tried so many times, read the manual, call friends but no luck. I am tempted to "explode" my drawing.

recommend a good way to indicate the location of cross section sample lines in a profile view (of same alignment) as vertical lines? the sample lines have been created at user defined locations from polylines, and do not follow a particular station order. my first thought was to use transparent command to draw line in profile view using station from plan view, but i have in excess of 100 cross sections, and that may be time consuming.

What I need to do correctly, I'm sure the picture will explain better. I know I could use multiple masks stacked on top of each other or some similar method, but I'm looking for something less convoluted and neater.

I'm working on a windfarm access road with tight bends that need to be 2.5m wider than the straights. I have created offset alignents and the corridor with no problem but how can I label the widths to show the variation in width at the various locations. The road is at the full width (7.5m) between tangent points and then tapers to the standard width of 5m
I have shown simple aligned dimensions on the screenshot but I'm sure there will be a way to do this automatically - won't there?

I'm attempting to use the Superelevation tool on an interchange. I have 4, 1-lane ramps that I need to apply superelevation to. The three issues I have (so far) are:
In the Calculate Superelvation Wizard...
1. In Roadway Type, I don't know what to choose, I'm leading toward Undivided Crowned (center Baseline ) because my assembly (as of right now) is set up as an undivided crowned roadway (with the crown on the west travel lane edge). Which Roadway Type I should choose (for a 1-lane Ramp with different shoulder widths?)
2. Moving on to the the Lanes category doesn't matters. I uncheck symmetric Roadway, hoping I can choose "0" for the number of lanes on the Left, or at least put the lane width down to "0" but can't do either. I uncheck the Symmetric Roadway and it still makes everything symmetric (it acts as though it is still checked?) I only want to show a single 15' lane. (I even tried to use undivided planar, and put both lanes at 7.5'each, but then I still have shoulder issues...)
3. Move to the Shoulder Control. Why doesn't it give me the option to do different shoulder widths? On ramps it is very common (at least in Wisconsin) to have an 8ft shoulder on the right and a 4ft shoulder on the left. How can I type in 2 different shoulder widths.

I am not a programmer and can not just load this sample as it is a .cs file. How would I go about using the code already provided to create a plugin into my AutoCAD to be able to use this command?

I have a road corridor and need to create sample lines at a 50m interval, as well as at every horizontal and vertical turning point. While the 50m stations and the horizontal turning points are easy to add (using the alignment), I can't seem to find where/how to add the vertical points (they have to be extracted from the profile).
Running the Feature Line Report I noticed the horizontal turning points are not used in the report: it only reports the 50m stations (so I guess the same will happen to the vertical points?).
how to add the vertical turning points to the sample line group and how to include both horizontal and vertical points in the Feature Line Report.

I am trying to use object snap (intersection) to position the end of my sample lines at the intersection of the sample line with a polyline. The object snap works with sample lines left of the alignment centerline but not on the right. How do I correct this?

I draw an alignment for road. I turned off design criteria and i used data from manual for my country Slovenia. I need spiral in, curve and spiral out on alignment. Finally i got that alignment. Then i insert sample lines along the alignment. Then i saved autocad civil 3d file and shut down the program. When i reopen file, i see that sample lines after the spiral in being erased. Sample lines stayed along first tangent, after that they were erased.

I have an Object ARX application where I consult a TIN surface for elevation samples. I need several thousand point's elevations in a straight line.
I have the surface declared as
CComQIPtr<IAeccTinSurface> mTINSurface;
And given coordinates (x,y) I can easily and successfully find the elevation using
//x and y are given double valuesdouble z;HRESULT result = mTINSurface->FindElevationAtXY(x, y, &z);
//+error treatment
This, however, takes a lot of time when I have to do it thousands of times inside a for-loop varying the x-coordinate. Reading the documentation on IAeccSurface I found the Sample Elevation method (I don't paste the link here, it's pointing to 'invalid HTML' and forbidding me to post). In the hopes of improving performance, this is what I tried:
SAFEARRAY* safearray;SAFEARRAYBOUND bound;bound.lLbound = 0; //zero-basedbound.cElements = number_elements; //does this define the number of samples?safearray = SafeArrayCreate(VT_I8, 1, &bound); //zero based, safe array of X,Y,Z doubles
CComVariant variant(safearray);variant.vt = VT_ARRAY | VT_I8; //type: safe array of doubleHRESULT result = mTINSurface->SampleElevations(x,y,n_x,y,&variant); //sample in line
This is what I took from the description given by the documentation; that the last parameter should be a "VARIANT containing a zero based, one dimensional safe array of X, Y, Z values. ". My problem is that 'result' is always E_FAIL - and I'm not sure why - and 'safe array' is filled with zeroes.
I have the following questions:
Am I passing the right parameters? I have little experience with VARIANT and SAFE ARRAY types.Does the entire Sample Elevation operation fails whenever a single elevation cannot be found? (I have sections without elevation information in the surface - I'm sure the first point (x,y) DOES have a valid elevation value, though). Would I really see performance gain by using Sample Elevation instead of multiple FindElevationAtXY, as I assumed?When calling Sample Elevation, I'm not entirely sure how the sampling is considered. Does the method recognize the size of the array and divides the distance between the initial point and ending point equally, resulting in that many samples?

In Civil 3D we can create several new sample line groups and their sample lines can have the same name in other sample line groups.e.g
SLG_1:
Sample line names:
1
2
3
4
SLG_2:
Sample line names:
1
2
3
4
However, If I create a new sample line group with API and after new sample lines, if other sample line name(of other SLG) has the same name, Civil 3D throws Exception.

I have an ObjectARX application where I consult a TIN surface for elevation samples. I need several thousand point's elevations in a straight line. Initially, I was making thousands of FindElevationAtXY calls, but that proved to be somewhat slow, so I searched and found SampleElevation in the documentation and was hoping it'd provide me with performance gain.
I had some problems, due to my inexperience with VARIANT and SAFEARRAY types, but now I get what seems to be correct results when passing an initial and ending point. Here's a code snippet of my call, which succeeds and gives me the correct elevations;
HRESULT result = mTINSurface->SampleElevations(x,y,n_x,y,&variant); //sample in line
Note that I'm sampling a line along the x-axis (y constant).
The problem i'm facing is that the number of samples along the line provided by the method is far smaller than I expected. I need thousands of points along this line (in fact, I want all points with exact round x-coordinates), and no matter what size I provide for the safe array of doubles given by 'variant', I get only a few hundred points. Furthermore, I've checked and the offset between any two points in the resulting sample is not constant, nor are they the same when I sample a different line (increase y coordinate by one).
Here are my questions: Why are these points chosen by the method - I mean, are they chosen because they are somehow 'significant'?Is there a way to specify the number of points I want along this line?Would it be at all possible to determine a constant offset for the samples (i.e., I want coordinates at specific points x-units apart from each other)?

I just got a topographic map of some land we plan to develope, and would like to work out some preliminary earthmoving analysis.
I would like to sample that surface at very specific locations -- I could produce the required points in PNE format.
What I want is to find the way to: (1) import those points, (2) sample elevation from the surface at those locations, and (3) export the 3D poitns in PNEZ format.

Creating sample lines at a specific increment within a range starting from the start of the range is impossible unless the start of the range is divisible by the increment. This is a defect that needs fixing.
Meanwhile you'll find me typing in the 93 locations for my sample lines. I believe this is what we made computers for.

I have some sample lines that highlight utilities needing a section view. I've now moved my sample line to highlight the true cross section stationing for these crossings. Why doesn't the station value update for the sample line once this is moved. For some reason I remember the station text on the sample line updating itself automatically in the past.

I'm working on cross sections and ran into a problem. I had to edit my surface but it wouldn't cooperate with me. So instead, I just erased the whole surface and restarted it. After I got my surface the way I like it, I added my sample lines to where they are supposed to be. Problem is, my cross sections turned out blank.
So for now, I skipped to create a surface profile and see both of my surfaces available on the bottom. The old one I deleted and the newly created one. It won't let me go to the bottom and erase the old deleted surface. When I go into my toolspace-prospector....it only shows my newly created surface and nothing more. Is this a reason why my cross sections come up blank?
I'll show you a pic of my toolspace with just the current surface and another pic of the "create a surface profile" showing that it still has both the old and new (all in CAPS) but it won't let me delete the original.

When creating a profile with right/left samples, the sampled profile does not show the gutter when crossing an intersection. If you do a quick profile of the area, it shows the gutters. See images below...

Where is the setting for the sample line label background mask? I have some sample lines that will be plotted on top of an aerial photo, and the black box background looks terrible. I'd like to turn it off. I found the contour label background fine and I switched those to False without much of a problem, but I can't seem to locate the ones for the sample lines.
