AutoCAD Map 3D :: Point Cloud Not Aligning?
Mar 8, 2011
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).

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.

how to access the positions of every points in pointcloud(.pcg files)?
Isn't it available in ObjectARX.NET 2012?or should I write my own warpper for .NET?

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?

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?

Using Civil 3D 2013, Faro Scene 4.8.2.25521, Kubit PointCloud Pro 8.0.4.7.
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?

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 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'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.
I have AutoCAD Map 3D 2011.

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'm really wanting to utilize CS5's powerful 3D capabilites, but am at a loss on how to properly align 3d items in perspective to the filter Vanishing Point's planes.
I'm building a digitial room setting, and want to place a simply painting (extrusion created with Repousse, texture layer merged down onto 3D layer) on the wall in proper perspective, with an extruded canvas like so:
This took plenty of time to accomplish. Nudging, moving, stretching, etc.. You can see my gridlines of course there created by the Vanishing Point filter. Is there an easier or quicker way to match up 3d objects within PS to these perspective planes other than doing it visually this way?

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

I would like to layer them in such a way that the orage circle below is put in front of the green circle. Essentially, I need to select only the part of the orange circle and bring it to the front while leaving the other part of the circle alone. Can this be done in Illustrator?
In summary, this is what I am trying to accomplish: Green over blueBlue over yellowYellow over orangeOrange over Green
Also, is there a way to use a tool inside of illustrator to arrange the locations so they are all 100% perfectly alligned and meeting in the middle without "eyeballing" it?

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.

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 am trying to index an ascii type Point Cloud. The file is exported from GOM Inspector program and file extension is asc. There are some parameters in GOM for exporting the point cloud. For example you can chose "," or "." as separator. I believe the problem lies in this area. I believe the syntax in my file is wrong. I have tried to find instructions of the file format / syntax.
