AutoCAD Civil 3D :: Increase Number Of Points In Point Cloud?
Feb 21, 2013
I have a point cloud with 161 million points in it. This is basically fine and works well but I need to create equally high resolution surfaces from certain regions of the point cloud. No matter what size I choose my export shape, it will only create a surface from a ridiculously small 750,000 odd points, a 'feature' which has been documented on these forums before. I have POINTCLOUDDENSITY set to 100.
My question is, how can I build a surface from this high resolution point cloud data that has more than 750,000 odd points?
I'm thinking about mosaic'ing - ie. making several smaller surfaces over the required area and pasting them together.

I have a point cloud dwg. Is there a way to increase the number of points displayed? The properties of the cloud say there is 14,000,000, but it only displays 34,000. Is there a way to increase the 34,000 number? See Image.

I know that there is a limitation on the numbers of points added to a surface from a point cloud. But I'm curious how Civil 3D determines which points to exclude from the surface. Is there a special alorithm/criteria the software uses?

When I import points from a survey database there is a very large new number being assigned to points that have overlap/numbering conflicts.
I had some survey from one source that was in the 1000 pt # range & additional survey that was in same numbering sequence.
When importing the points I chose "Resolve all" it is renumbering the Point number value to the 5xxxxxxxx range?
Is there some setting where I can change this to a lower # or how/why this is happening?
Next Point Number value @ Settings Tab>Point>Commands>CreatePoints>Point Identity>Next Point Number = 3.
I've attached a couple of captions illustrating the issue.

i need to know if there is any way to control the points in the point cloud.
1. either only import the point cloud in a polyline area i specify
2. add all the points within a boundary not limited to the pointclouddensity = 100, freaking default is 15 almost cost my job today. extremely stressed out right now.
i am talking about extreme lidar surveys. 1km 1km LAS/0.5m contours/xyz files times 355 of them. covers a 2km wide corridor. but i only need 100m wide after i define the road alignment. no need to have all the extra points.
right now i densify the heck out of it and end up like 5-12m points. decent but not good enough because the geotech is bitching about that accuracy is not good for some feasibility study. or is there any software i can do this besides civil 3d.
what i want can also do is automate the 'add points to surface" under point cloud and have the software do multiple boundaries without having me baby it over the night. right now every click is 5 minutes and adds like 400k to 1 million points. Civil 3D 2012

I was wondering if there is a way to select specific 3D points out of a point cloud (.pcg). I am new with Autocad and handling of point clouds .
I can think of various things that you might want to do, as in clean up a bit the data or even delete some areas that you are not interested with. additionally, one might want to do some calculations, so selecting points first and the running a list script to use that points can be handy as well.

In uploading the Point input data into the AutoCAD Civil 3D 2013 software program, is it possible for me to add more Point Attribute items after Point Number, X, Y, Z? I need to have the chemical results/data attached to the (sampling) Point that has the Point #, X, Y, Z - like Point Number, X, Y, Z, Arsenic, Lead, Mercury in the input .txt (or .csv) file.

Im still new to Civil 3D and i would like to know how to connect inported points using 3D polylines. I imported my points from Excel in a PNEZD format. How do i get the 3d poly line to snap to my points so I can Connect them? someone mentioned using a feature line to connect the points but im not sure how or what that would do.

I have been searching for a solution to a problem i have been having. I have a point cloud, and I am wanting to TIN it to create a surface.
When I use the Create Surface tool, no dialog box appears. Everything I have found seems to rely on this Dialog Box. How to get it to display?

Is it possible to turn off the bounding box on a non-Civil 3D, .PCG point cloud that was indexed into Civil 3d directly from the Faro .FWS file using the "POINTCLOUDINDEX" command?

How can I rotate my point cloud to have the front view on the top. I want to optimize the surface creation on the lateral surface of a deck and not on the ground (top) surface. I think to rotate 90 degrees on the X or Y axis.

Civil 3D point cloud tools (ribbon) are different than AutoCAD's. Is there a way to bring up AutoCAD's point cloud ribbon in addition to Civil 3D's ribbon?I guess if the commands are the same, I can just copy the ribbon from AutoCAD's CUI and plop it into Civil 3D's CUI.
But, is there a better way or is there something I'm missing?I'm looking for the clipping tools and the point cloud display otions (scan colors, elevation, normal, intensity, etc.)

I am working with a Lidar dataset that is over 34 million points. It covers an area far larger than I need for our project. I have experimented with point clouds and am able to process and generate a surface from the data by applying a clip boundary to the surface. The problem with this is the surface only has about 540k points out the total dataset and it appears that the points have been greatly reduced in density. I am thinking this is due to the way C3D limits large data sets to display only 1.5 million points and thus my surface data is highly filtered since it is extracted from a small area of the dataset. I have tried setting point cloud display to 100%.
can I somehow filter my point cloud so that I can reduce the area of coverage and thus increase the density that is extracted into my surface?

while i am trying to load my point cloud files the points appeared in the model but not all points
i entered to the setting of the point cloud from the toolspace toolbar , i found that there are about 32 million points but only 700000 points are displayed in the drawing. Is there a way to display all the loaded points in my drawing to show all the points since i need to render a high resolution pictures for my lots.

2012 SP2. I get this very descriptive message while trying to create a point cloud: The following error occurred processing the point cloud data: An error ocurred in data processing.
I've previously created point clouds from the same data (ENZ comma delimited) without a problem. I believe this was done before applying SP2. Any problems creating point clouds since SP2?

I might be missing somehting completely, but I am reading with Civil 3D 2013 you should be able to clip a Point Cloud, but I am not seeing the clipping panel under the point cloud tab.

I see that the Point Cloud Feature Extraction is now part of the Productivity Tools for Civil 3d 2012. Are these tools available in 2013? I am not seeing them anywhere. It seems goofy that there would be more tools available for the old release - what's the incentive to make the switch? Would you expect they will be available for 2013 sometime soon? I'm not complaining, I really like 2012

See pic. Top pic is 2013 point cloud properties. bottom pic is 2011 point cloud properties. 2013 has a new 'point cloud adjust' option in properties.
Both drawings have same 'Lidar Classification' Style, but 2013 is all gray. I tried changing some fields inside the properties for 2013 under the point cloud adjust to no avail.
why this is like this and what I need to do to see the different colors for the different classifications.

I have a surface based on a point cloud. I decided to add a few more tiles of data to the point cloud and was expecting that the surface would update (after rebuilding) to include the new extents - but there was no change. The surface doesn't have any boundaries or breaklines but does have edits.
Do I need to add points to surface again? Will this duplicate the orignal point data or would it just add the new data. I didn't want to lose my edits if possible.

It was in Feb - March 2012. I was then using AutoCAD Civil 3D 2012. I had faced a problem of getting ground data for a large surface by using satellite imageries processed by some government wing of USA (NASA?), have lost track of it.

I am trying to set several hundred points along polyline verticies with the point number starting at 5000. There are no other points in my drawing, yet everytime I start the process, it begins at 1. I have set 5000 at my Next Point Number under Point Identity in the Create Points toolbar. I have also verified that the 'Save Command Settings" is set to yes under the 'Commands-Create Points'. We cannot get this to behave as desired.
This is a 2D polyline with no elevations.

I have a method to create new point group.
In this method I add as parameter one vector which contains point numbers.
string Numeros_Incluidos = "";
//buscamos todos los number point según su id y creamos una cadena string
foreach (uint NP in listaNumberPoints)
{
Numeros_Incluidos = Numeros_Incluidos + Convert.ToString(NP)
[Code]....
I create a string called "Numeros_incluidos" that it is a chain of all numbers.
e.g:
"1,2,3,4,5,9,10,11,15,18,21,22,"
However I would like to create one function to create this string more organized as:
"1-5,9-11,15,18,21-22".

Question 1.In C3D 2013 is there a ceiling to the number of points allowable in a C3D surface? Is it 1.5 million?
Question 2. In C3D 2013, when creating a surface from Point Cloud data is there a maximum point count based on the answer to question 1 - or is a different point count limit applied?

How to change the number of decimal places of the elevation of points?
as the points are labeled with their elevations, I couldn’t find how the number of the decimal places of the elevation be chosen. In this case, I wanted to let the number of the decimal places to be zero.
How to set the number of the decimal places to be zero or 1, for example? how to sepcify it height (size)?

I just received a drawing with a bunch of points in it. One of the layer is called V-ROAD-CNTR-PNTS. Unfortunately, the point number, description, and elevation are all in that same layer. How do I keep just the elevation turned on but turn off the point description and number? When I turn off or freeze the layer V-ROAD-CNTR-PTNS, all three disappear. I just need the elevation showing.
Attached is an image of my screen.

We have been bringing points directly into a 2012 Civil 3d drawing using the same method for quite a while. We use a numeric descriptor code and the points are filtered correctly. In this particular drawing, one description code was singled out and "locked" in the drawing. The points and symbol show in the drawing slightly muted but when I try to edit the points I am unable to do so. I have tried the "unlock" command with no result. The symbol displayed by the point number is a red circle over a pencil.
