AutoCAD Civil 3D :: Creating A TIN Of Planar Surface
May 27, 2012
I can't seem to create a planar surface that shows up in the tool space as a TIN.
Some background, I have a TIN of a pile of dirt that I created from a point cloud (it shows up in the toolspace under the surface section). I also have a plane that intersects that dirt pile which indicates ground level. I want to be able to calculate the volume of the dirt pile by creating a volume TIN with the ground plane and pile TIN, but the ground plane does not show up in the toolspace under the surface section so I can't use it to create a volume TIN. I created the plane with the planar button in the ribbon and manually lined it up with the pile.
How can I convert this plane that is clearly in my project but not in the list of surfaces in the toolspace into a TIN to use in a volume TIN?
I'm running Civil 3d 2013 and you'll probably have to explain things like I'm 5 because I'm not familiar with the interface yet.

I know there is a procedure to turn a surface into a planar surface, but i don't really know if autocad can do that, or how to do it. By this procedure i mead transforming a cone into a surface, a cilinder into a surface for example, but in my case the main surface is not a basic surface (as show in the image) and the procedure is quite tricky.

Is there a way to print planar surface of any model in inventor 2012? I know that autocad is able to print planar surface, but inventor is much better to use.

I am not sure what I am doing wrong but when I use the bend tool I am getting weird results. Does the surface to be bent have to be planar? See photo attachment.

I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.
i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline. This seemed to work, but when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.

If I change a point or link code in one of my subassemblies, is there a way I can build my top surface using those?

In the Surfaces Tutorials: Exercise 1: "Creating a TIN Surface". The first instruction is to click "NEW", which I did. I selected "Surfaces.dwt per instructions and clicked open. I have executed these steps a number of times to be sure I am doing what the instructions say. But, every time the same thing happens. "Drawing2.dwg" opens instead of "Surfaces.dwt". I also make sure the file type is set to dwt.

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 am trying to create a surface from a corridor. I have a sub-assembly attached, which I believe is working correctly. I managed to create the empty surface and when I try to add surface data nothing seems to happen. I keep changing the specified code to Base which is my finished gravel structure and hit the + but again nothing seems to happen.
Ultimately I am trying to determine a volume between my corridor and original topo.

I have a project that I need to map the terrain as a tin solid so that I can do some cut and fill analysis. I have downloaded a orthographic and elevation data from the USGS website. I cannot get AutoCAD civil 3d to create the contours properly.
My current workflow is: use mapwspace to bring up the task pane. Connect to the geotiff image in the 1-153383539 folder. Then I try to create the contours and the option is greyed out.

This is the first time I have imported a .dgn file into Civil. The drawing contains contours lines with Z elevation data. When I create a surface using this geometry (polylines + some lines) the surface seems to be scaled in the Z axis by 12.
For example pline (from dgn) is at elevation 46' but the Civil3D surface is 552'
I assume this is a setting in the Surfaces dialog box, but I cannot find it.
Also the elevation field in Properties from the dgn contours is weird. For example, in one area the (pline) contours display -28', 26', -24', -22', -20', -18' in Properties but Civil3D interprets this as a downward slope - which is the actual field conditions. I don't understand the conversion going on here.
The geometry of the pline and contours generated from the surface seem to line up in a side or isometric view (see attachment).

Been chatting with an architect in my office, and he was asking me if we could make our TIN surfaces smooth. I cannot find a way, would it take a 3rd party program? He wants it like the image i attached. How to achieve this with a TIN surface?

I will try to write this as clearly and shortly as possible.
I have two surfaces created lets call them Surface A and Surface B.
They have different elevations in different areas, sometimes Surface A is below Surface B and other times Surface B is below surface A.
Is there a way to easily create a Surface C which is a combo of Surfaces A and B taking which ever surface is lower?

I´m having problem with creating stl file from surface. I need to import stl in another program for rockfalls.
I have create surface from contours, then extract faces, extrude them, union and I got solid..
I have export solid like stl file... But in another program my surface is not smooth, like somethning went wrong while exporting stl, because in autocad civil 3D 2012 everything looks good.
I have found out how I can increase facetres to 10, but It has not affect to my stl file. If there is some another parameter for better resolution of stl files?

They send me a file that has polylines as contours and when I try to do the surface adding contours an error appears saying that the breaklines couldn't be added because they crossed a breakline, I don't understand why.

I am building a surface and started looking at the triangles and found that some are going to non-existant points. I have unfrozen, checked, etc. all of my points to make sure they are not in the drawing.

I am trying to create grading slope from a Feature line that was created at a constant elevation of 609m. I want to create a slope of 3:1 from the feature line to a surface I created. I recall in AutoCAD Civil 3D 2011 that you could create a slope directly to a surface. Is there a way of doing that in 2014 or did I simply forget a step when I created my Grading Groups?
I created the grading group using the Grading Creation Tool Pallet and selecting Set Grading Group. Then I set my target surface to the one I want to grade towards. I thought all I had to do than was go to Create Grading select the direction of grading and the slope. I thought the slope would continue to the target surface but it asked for a distance for grade that would throw off any volumes I want to pull off.
Did I have to create a new surface for my Pad at 609m than grade from that and how would I make sure my slope continues till it contacting the surface I want to target?

I have drawing giving to us for a senior design project. I'm trying to create a surface to so that I can analyze cut/fill. Not sure if what i'm doing is right or wrong, I've never used civil 3d. But i'm getting break-line errors whenever i'm trying to create the surface from the contour lines.
Heres a link i took of what i'm doing on youtube [URL]........

I am using Civil 3D 2011 and wondering how to create just one contour on an existing surface at a specific elevation. I need to show where floodwaters would get to at a specific elevation so that contour would be the easiest way if I can contour the surface with just 1 elevation. I don't want to have to create 0.1' contours all over the site and then remove all the extras.

I was given a job where i need to create a surface from a gis file. have been messing with my civ 3d 2013 a little bit and have been able to get a surface comprised of a bunch of polylines to appear (not a true surface). I will need to create profiles so i need a true surface. I downloaded a compressed shape file from the county and need to know how to insert this into a drawing and build a surface using my own surface style.
The files i have to work with:
.dbf
.idx
.prj
.sbn
.sbx
"autocad shape source"
.shp
"autocad complied shape"

I have been given a survey on AutoCAD which was orginally 2D with the levels written in text next to it. I changed each point (690) to include the level in the Z-direction. I am trying to calculate volumes of topsoil removal and then cut anf fill volumes.
So I opened up Civil3D in metric template and imported my drawing as I have not been given a ddata file with the co-ordinates. Unfortunately I am having trouble creating a surface between the existing points.

I am creating a surface from polylines and the surface is not being created per the what the polylines represent. These are simple 5:1, 3:1, and 3.5:1 slopes. The surface wants to create curves instead of straigtlines (see attached).

The engineers at my company digitize proposed contours in a drawing and then they want me to create a surface out of the contours....the contours usually are 2 foot contours with areas that the software tends to translate based on the contours that I selected to create the surface.....I then usually need to create a profile, which does not look accurate compared to the contours, such as low spots etc...............
My question is since the engineers at my work do not how to use the software, and I am not an engineer, making the profile look a certain way sometimes needs to be tweeked by me.... How to alter the proposed surface?I am pretty sure that feature lines cannot cross contours that I have selected to create the surface?

I am having some trouble creating a TIN from a point layer in Civil 3D 2011. Would the best course of action be to extract the points from the drawing and creating a surface from there, or is there a way to create the TIN around the existing points in Model space?
I'm much better versed in AutoCAD, but excited about furthering my understanding with Civil3D.

creating pipetrench1 on my surface.
Currently, I wanna make an alignment from a 16-inch pipe, which will then be positioned inside a trench.
I have tried several times to generate the corridor, but turned out failing.
Im guessing that i had inserted some parameters wrongly.
Here is the sample drawing: [URL]

Is there a way to create a surface by manually selecting the points instead of creating a point group? I survey stockpiles for a local construction company and calculate volumes for them.
There may be 50 piles on one site and it would be a lot easier to create a surface by selecting the points manually instead of creating so many point groups.

I am having a problem using 2014 civil 3D. When I import las files and create a point cloud, and go on to make a surface from those points, it is limiting the "number of points added" to 340134. I am using the lidar las files which each tile or file has an average of 12 million points, and I have tried to create a surface using one file, and up to 28 tiles (where there should be 340 million points). Regardless, one of the files contains 12 million points and I do have the "point density" set to 100, and the "real time density" set to 100. Why will it only use 340,134 points? I have tried all options from "point cloud extents" to "window" and same result. All the points from the cloud are there and displaying fine, it just seems civil 3d is limiting the number of points used for surface.
