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.

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?

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

how to match up certain points. I have imported 2 point clouds and have tried to use the 'align' tool to specify three points from the source object (cloud) and three points from the destination object (cloud). When doing this, it does not properly align them. The point cloud makes it difficult to select the exact point I would like to align, since there may not be a point at that exact location, but close to it. Does AutoCAD require the points in alignment to match up perfectly or is it capable of doing a best fit?
Also, is AutoCAD capable of creating a solid 3D piece from the point cloud? I would like to take all of my points and make a smooth object.

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 can get my stylised map from Promap into Map3d 2011, and I have tried importing the point cloud data which I have as a esri ascii grid file, it is basically 3 columns of numbers:- for north, east and height.
Unfortunately when I choose to format as nez (when importing) it turns the whole lot round by 90degrees ...
I have tried importing it as enz but no joy, and also in niether case will it align with my map (have tried using coords and not using coords).

I use POINTCLOUDINDEX to convert .las file to .pcg file, then I use POINTCLOUDATTACH to add .pcg file to model space.
How can I get the 3d coordinates of points in .pcs files?
I use ObjectARX in .net.
I can't find any Entity types related to pointcloud, should I find in other namespace?

I am trying to trace part of my point cloud, which has been aligned according to a new UCS I set. Drawing on the top down view, a poly line works fine out in the black ether or the model space, however when I attempt to trace over the point cloud it shoots way off in the distance.
My node snapping is turned off of course, but this only happens when I click over a part of the point cloud, as if it was snapping to the cloud and getting confused.
When I turn snapping off completely I can click anywhere I want and I'm fine. This suggests to me that it is a snapping issue, although I was under the assumption that "Node" was the only snap setting that related to point clouds.

AutoCAD 2013 point clouds can have a 3D bounding box displayed, and you can grab the grips to edit the box, x, y and z. It's a nice feature.
Using vb.net, will I be able to programmatically move those bounding box points?

Supposedly there's a way "To Convert One or More Surfaces to Solids":
[URL]
However, I'm unable to find Home tabSolid Editing panelThicken.
I'm trying to take LIDAR/Point Cloud data and 3D print it (in the end, I need to make an STL file). I've created a 3D surface from Point Cloud data which results in a Raster Layer. I do not know how to convert the surface that's in the Raster Layer into a solid.

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.

I'm working with a point cloud in 2013. The color comes in when I convert to .pcg and import into Revit. But I can't get the color to display in CAD. I've heard it may be a visual style problem, or a setting in my hardware acceleration, but nothing seems to work.

I'm trying to access the style manager to allow classifying LiDAR point cloud based on elevation. I have been able to attached the point cloud and see it on the drawing. For some reason I can't see the Point Cloud Menu, which I believe should be showing up beside "Express" menu on the top toolbar.

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.)

Having a lot of issues manipulating points on paths in Illustrator CC - this is a fundamental feature of creating vector graphics and it's very annoying I'm paying for this and it's just not working. Eating up a lot of my time simply because I can't select or convert or add the anchor.

In previous version you can rotate the UCS around the Z axis by tying UCS Z at the command prompt and then you were prompted to select two points to defin the angle. Now it uses a point at the ucs icon as the first point and only allows me to pick the second point. Is there a way to pick two points to define the UCS angle? I tried setting the UCS Origin to the first point and that did not work.

I want to move a few snap points on a line but not all of them... Usually I would shift + click each individual snap point and then move but when I have a lot of points it gets pretty time consuming.
If there was a way to drag select multiple snap points in a line.

I have 3d scan of aircraft door frame (see attach) in point cloud format. I'd like to overlap 5 different frames and construct a new 6th frame by averaging out all of the points.
At the moment, the 3d data files has no surface and I'm unsure if adding surface with the construction of the 6th frame. I will also need to take into consider alignment, point density, and orientation when overlapping all of the frames before I can start work to average all points (Note: each scan are taken from 5 different vehicle).
I have both Rhino3D and Autodesk Alias Design 2012. What are the logical steps to do in this case?

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.

I have a problem with the management of the cloud of points with autocad 2013. and precisely:
- What is my need: using orthogonal views create section planes of small portions of a cloud to be scanned.
- What is my problem: When I align a view, the bounding box is not aligned to the same, so this involves a wrong cut plane to create the section
