AutoCAD Civil 3D :: Numbers Of Points Added To A Surface From Point Cloud?

Jan 7, 2013

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?

AutoCAD Civil 3D :: Surface Points Added From File / Can Change Their Style

Mar 14, 2013

I can only change the layer color.

But I can't change the cross simbol, its drwaing scale.

Also cant view the point number,....

Maybe I cant view or set these properties when points were added using   "Point Files" option.??

AutoCAD Civil 3D :: Points Names Without Assigning Point Numbers

Jun 15, 2009

I'm trying to import a GPS coordinate file where our Surveyor has used both Points Names (Alpha-Numeric) and Point Numbers. see below. I have setup a Point File Format for Pname, North, East, Elev and RAW Description, to import this comma separated point file. The problem is that Civil 3D does not want to seem to use a numeric point name as a Point Number, instead the number is used as a Point name and Civil 3D assigns a Point number from the next availible point number. Is it possible to automatically, when the Point Name is a numer only to also assign it the same value as the Point Names?

I would really want Civil 3D to allow users to use Both, Point Names without assigning a Point number.

AutoCAD Civil 3D :: How To Assign A Set Of Points A Sequence Of Point Numbers

Jan 17, 2012

What I wish to do is to assign a set of points a sequence of point numbers (or custom properties) of my choosing. For example, I have the following points:






I wish to assign point 100 -> 1000, 105 to 1001, 107 to 1002, 104 -> 1003, and 102 ->1004. Basically, I am looking for a command or utility that implements the "TCOUNT" (using select-order) command, but for Cogo points instead of text. The renumber points command appears to only work with offsets, and does not eliminate gaps. I can sequence the points if I select the points I want, then copy them -> set duplicate points to sequence from the range I choose, but this does not allow for reordering of point numbers. I tried individually selecting them in the order I wanted, but didn't change the order in which they were numbered.

Alternatively, I can leave the point numbers the same, and assign a user defined property that I can use to sequence the points in the order of my choosing. However, I'm not sure how to go about assigning the sequence I wish short of typing in each value individually; obviously non-ideal.

A third possibility that presented itself to me was to create new, correctly sequenced points that overlap exactly with the old ones, and then somehow merge the two sets together. Would there be a way to merge the old points and the new ones based on the fact that the two points have the same X-Y coordinates? Preferably done in CAD itself; the last resort would be to export both sets of points out to excel, then do some fancy manipulation in excel, then reimport into CAD.

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.

AutoCAD Civil 3D :: Updating Surface To Recognise Modified Point Cloud

Dec 13, 2012

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.

AutoCAD Civil 3D :: Add Points To Surface Not In Point Group?

AutoCAD Civil 3D :: Query Point Cloud Boundary Then Add All Points Within Boundary

Nov 9, 2012

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

AutoCAD Map 3D :: Selecting Points From A Point Cloud

Nov 22, 2011

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.

AutoCAD Civil 3D :: Breaklines Which Aren't Added To A Surface?

Feb 29, 2012

I am using a breakline to establish contours around the foundation of a building.  I've done this in the past with no problems.  Now I'm getting an Event Viewer, Error message saying that the breakline wasn't added to the surface because it crossed a point or crossed another breakline.  In one case there wasn't another breakline in the drawing. 

I've used 3d polylines & others to establish the breaklines.

AutoCAD Civil 3D :: Large Surface - Converting Points To Cogo Points

Mar 5, 2013

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?

AutoCAD Civil 3D :: Get A List Of Available Point Numbers?

I just had an internal request for this and I had to look it up. So I'll share what I found and have a place to find it myself next time.
One way to do it is to select a COGO point to bring up the COGO Point Contextual menu tab. In COGO Point Tools you can select List Available Point Numbers.

AutoCAD Civil 3D :: Point Cloud Different Tools

Nov 19, 2013

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.)

AutoCAD Civil 3D :: Clip Or Filter Point Cloud

Sep 1, 2011

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?
