AutoCAD Civil 3D :: Create Points At Surface Vertices Along Sample Lines
Jan 9, 2013
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).

How to create points at the vertices of the lines in the regular AutoCAD? ’m wondering if there is a way to automatically create points at the vertices (or only at the end points) of existing lines (or polylines)?
Is this possible in the regular AutoCAD?

I have 4 points (from "Points from file", I created Points #1, #2, #3 and #$ in the non-linear fashion).
1) I want to create 4 straight lines (connecting Pt#1-Pt#2, P#2-P#3, P#3-Pt#4, P#4-P#1) by using some Commands. What Commands in the Command Line should I use to create these 4 straight lines from these 4 points?
2) I want to create 1 parcel (connecting Pt#1-Pt#2-Pt#3-Pt#4-Pt#1) by using some Commands after "Parcel Creation Tools" => Draw Tangent-Tangent with No Curve is clicked. What Commands should I use in the Command Line to specify these points to form a parcel?

I just upgraded to Civil3D 2014 and Windows 8. When I create a TIN surface using a DEM file no contour lines are displayed. Points are processed and triangles are created and can be displayed but no contour lines. Contour line layers are set to display in the style file.

So I received a whole bunch of contours from an architect. They are lines and arc. big sweeping arcs. Whats the best and fastest way to create a good surface. I can change them globally to a polyline but I need to add vertices like every 5 or 10 feet to get a good surface. Can I select multiple feature lines (after converted) to add vertices?

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.

I know there are different ways to do this. Would like to know multiple options so I can see which might be quickest for me.
I have points with elevations and 2D plines at elevation zero drawn between them.
I would like 3D plines instead. This is the easiest way for me to transfer them to another drawing where I will make surfaces with them. I don't want to have to transfer the points over.
I can redraw the plines as 3D plines but this is time consuming and seems unecessary.
I don't want to have to convert them to Feature Lines either. I prefer they be 3D polylines.
Is there a simple command for this? I already have a surface containing the points and lines as surface breaklines.
Is there a project objects to surface command that will make these 2D plines at elev 0 into 3D plines while assigning elevations (and vertices) only at the current vertices?
What about a simple series of commands to convert the 2D plines to 3D plines, then force the 3D pline to take on the elevations of the points at its vertices? (I think this would be my preference, but don't know any of these commands or where to find them.)

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.

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...).

I have a large surface (over 1.5 million points and 20 000hectares)
I need to get a point file .csv from the TIN to be able to use it in another program.
-so i've extracted the points from my surface, but they are Autocad points.
-next step is to convert them to civil 3d points.
-I can not select them all when converting them or my computer crashes.
-so i select about 25 000 at a time, the converting takes roughly 10 minutes.
and i have over 1.5 million points to do.
how can i speed this up.
will more ram useful?

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.

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 am manually editing my section geometry by moving the grips and am wanting to remove some of the additional vertices that I don't need in a certain area. How to delete extra points? I can't seem to find a way to do this either graphically or in the Section Editor. I am using C3D 2010.

As far as I know there is no way to add or remove vertices on contour label lines. Is this correct?
If so it's another one for my wish list.

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.

I had to create a boundary map and place points to all corners. How to export these newly created points back into my data collector (Ranger) and also I'm trying to figure out how to print out a points list.
I stumbled on to this thread but I guessing that it's a different CAD year because my modify tab doesn't look like this. URL.....

is it possible to create a surface quickly in Autocad using 3d survey points on a DWG?
The way I did it was 3dpolylines and then lofting the surfaces. Quite time consuming.

I create the sampleline on the option "by a range of stations" so the sample lines were created on the horizontal geometry points. When I change the geometry of the alignament, the sample lines's local change or I need to do the process all over again?

I'm working with TIN surfaces, doing cut/fill comparisons for a surface mine.
My volume surface statistics show a cut volume of 5167.22 cy and fill volume of 8456.18 cy.
The sample line group volume report show cumulative cut of 5527.67 cy and fill of 8465.56 cy.
What could be some causes of this disparity. All reference surfaces are built from points and use a non-destructive boundary.

Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.
The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.
I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.
1. Novapoint is quite unstable and crashes alot
2. You cant create profiles out of 3d faces
3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface
4. A large surface made out of 3d-faces demands alot of computer power
So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.

I have a grid survey of points and I've entered these points into Civil 3D. Now what I want to do is use these points to create a surface so that I can create a slope analysis of the surveyed area. My problem is that I can't get the points into a point group.
I have a generic grid (15 x 15) of points set up and I've only used a portion of them (defined by the dimensions of the site). So I want to create a surface that includes all of the points that aren't set at an elevation of 0.

I have an "existing" surface built. But there has been some construction since my company surveyed the site. So, my surveyor went out and got the new points in the area of the new construction. I am trying to remodel the "existing" surface without rebuilding the entire surface. I have removed the old (demoed) points from the point group used to define the surface. But, the points are not being removed from the surface.

I built my surface by importing points directly, ie, not through the ribbon, so i have no points listed in prospector. i have been editing the points (mostly deleting errant survey points) and would like to export the final data set. The only step i found, was to show points in surface style, and then Extract Objects (of which i selected Points).
This seems to have no placed all the points into my DWG, but HOW do I export this files into a single text file??

I have alignement of wall or embankment. I have existing ground including this corridor river. I have also CSV file with points (x,y,z). On my sketch there is drawn. Points present FDL (flow defence level) maximum level of river in case of huge rain or other things. These are almost aligned. I need to transform it (project) into alignment. I have to create profile of EG, FDL (based on this point) and then create new profile of height of wall or bank. What is the best solution for projecting this points. I tried with grading (distance and grade0%) I tried then with offsetting this feature line based on points and used it as breaklines. Created surface had holes.Even real is worst because alignment is perpendicular in same places to river.
