AutoCAD Civil 3D :: Export 7 Million Points To Text File
Jun 21, 2012
i need to export 7 million points from a tin surface to text file with only NEZ in comma delimited format for Surfer 9 software. right now i have the civil 3d surface. but the export to csv stock reporting tool sucks. why the hell do you open the file and why leave an empty row between data points? so it's not usable.
also i have 12gb ram at work and it can't export surface points to autocad format ran out of memory. this is with surface display showing points and just the "dot" style so it's autocad points after export. i was originally planning on using "dataextraction" command in autocad to export to csv. worked on a small batch of file. so i think may work for the bigger file. but i would never know because i can't even get the points into autocad.
also yeah i would love to simplify the surface but it's so buggy that you asked it to remove 80% of the points it only remove 100k points at most out of 7 million. so not usable.
last resort is i can program something in vb.net but not much motivation on doing so.

I am trying to utilize Trimble's ability to export Points to an XML file. The XML file contains some additional Attribute data. I have created the new Point UDP's and also Created a new Point File Format. Here lies the Problem, when I go to the Insert Tab in the Ribbon and pick import from XML. It gives me no choices to select a Point File Format? It just imports the file with just PNEZD data only, and not my additional Attributes.

I am completely new to the forum and to Autocad. I am using version 2011.
I am working with irregular solids and after I SECTION them, I would like to export to a text file the data points that make up the perimeter of the sections.
Ideally, I would like to do it from the command line, but that's a secondary goal, first of all I would like to know how to do it.

I had to create a boundary map and place points to all corners. How to export these newly created points back into my data collector (Ranger) and also I'm trying to figure out how to print out a points list.
I stumbled on to this thread but I guessing that it's a different CAD year because my modify tab doesn't look like this. URL.....

I have a text file in PNEZD where D is XYZ. I have a description key for XYZ. I am importing this file into survey. When I import this file the points do not take the style of the description key, they take a default style from somewhere. What trick am I missing so that when I import points into survey they use the description key and therefore have the correct style.

I have been trying to simply insert points in a .csv file (PNEZD). The foints are taken SPC systems and elevations are in feet. I am using the imperial english template with no conversions. When i import the points from a file the points come in in the correct position but the elevation is in meters insted of feet!

My surveyor gave me a topo survey done in no particular coordinate system. He set up his total station on a PK nail and gave it a coordiante of (5000, 5000, 100). I used this survey to generate a surface.
I also have a site survey of the same site, done in state plane coordinate system. the two surveys have mulitple common points; pk nails, iron pins ect.
What i need to do is move the points for the topo survey over to the survey that is in state plane. A simple move command will not do this.
How do i go about moving these points to thier correct location without having to manually edit the .txt file?

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.??

I'm very new to Civil 3D.I've been given original topography in a .dwg file and a .csv file of the same topography after some dirt work.My problem is when I import the .csv file the points don't overlay the original topography.
What I have done is added the .csv points to the original topography .dwg with the "Points From File" option.

I have numerous text objects I want to rotate 180 while retaining each text objects insertion point. There's got to be an easy way to do this.
Long explanation: I created an annotation template to label pipe diameters on an imported shapefile. Everythings good, labels are parallel with lines, except for the fact that some labels are upside down. Is there an expression that would eliminate this? In my annotation template, my rotation expression equals the "angle" field of the object. My "quick and dirty" fix was to burst the annoation labels, and manually rotate necessary text, which wasn't a huge headache since I'm dealing with a relatively small number of labels, but in the future I might have hundreds of upside down labels.

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?

I have recieved a file with many points and would like to convert them into COGO points in Civil 3D. The problem is; I would like to keep the hole ID's as I convert, I've made a few conversions and lose the hole ID every time (not showing in Name or Description). Is there a seting I am missing to keep these? My aim to to organize the COGO points in different point groups.

I have a couple points that were part of an import event (data from a previous project) which I want to assign as control points for an incoming traverse, is there any way to assign those as control points? I can't seem to find a way to do that other than perhaps re-importing the specific points as control points and overwriting the existing ones.

I have a project that was started by leaving all the survey data inside the "All Points" group. So, I'm concerned that when I enter my as built survey points, that even if I put them into their own group, that the original surface will still look at them and just rebuild to my asbuilt data, effectively cancel out the purpose of the asbuilt survey. Will this happen?
I want to take the original points and put them into a group of their own, but I don't know if that will affect anything or not? I have several wetlands already designed on that surface with volume calcs already done too.
What should I do?

I have a lot of AutoCAD files which have embedded OLE objects (excel) inside. I want to be able to export only the text from the Excel OLE object using VBA (or Lisp, I don't mind which) without having to fire up the OLE application (i.e. Excel).
The embedded OLE objects have no link to any external files - so I imagine it must all be held somehow inside the AutoCAD file, but how it can be accessed?!!?
