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

Mar 7, 2012

Is it possible to add points to a surface without adding them to a point group?  I've got a bunch of ponds I'm doing and it will save me some time if I could just select the points, and not have to put them in a point group then add the point group.

AutoCAD Civil 3D :: Point Group When Importing Survey Points?

May 23, 2013

Sometimes when i import points Civil 3d creates a Point group in the drawing with the name of the point file, sometime it does not. I prefer when it does create this point group. It always seems to create a Survey Point Group. How do i control wether or not a point group is created in the import?

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 :: Moving Points Out Of All Points Group?

Apr 10, 2013

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?

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 :: Point Group For DTM

Aug 7, 2012

I am having a problem getting all the points I want to include in my DTM into a Point Group. The raw description inclusion of most double codes, codes with line designators and codes with size and description modifiers does not bring the points into the point group. (e.g. WL S,  CLF E,  PIN 18 where the description key set is created to size the pine tree by 18 and create a descriptor that says 18Inch Pine).

AutoCAD Civil 3D :: Point Group Creation

Nov 7, 2013

When point groups are deleted through the UI and then recreated via code with the same name the criteria such as the excluded point number list is included. It would be nice if it started with a clean slate once created and not keep around deleted point group.

AutoCAD Civil 3D :: Point Group Properties

Apr 23, 2013

I have a bunch of culvert points in my drawing and I would like to include all of the in the same point group.  They all have CUL in the raw discription but some are CUL 0.3 INV, CUL 0.4 INV, etc, etc.  

Is it possible to group all of these by just using the CUL somehow so that I don't miss any?

AutoCAD Civil 3D :: Set A Default Point Group?

Jan 20, 2012

How do I set a Default Point Group?  When creating points manually, I want them to automatically go into a certain/current point group, but since I don't know the point range prior to creating the points, I am having to continuously update the "include" points catergory.  I can set the default/current layer, default point style, etc, can I do the same with point group?  I understand about the "all points" group and the description keys that can be utilized in the other individual point groups to group information , but Is there a better way?  Under the point creation toolbar, there is a point group template, but when I create a point group thru there, it doesn't do anything but create the point group.  None of the newly created points go into that group....  what is the point of that option?

AutoCAD Civil 3D :: How To Use Surface Contour Label Group Class

Nov 6, 2013

How to use the Surface Contour Label Group class in the .NET API.

My first guess was that I had to create an instance object of the class and name it, and then use a "Create" method (e.g., CreateMultipleAtInterval) from there, like this:

Dim labelgroup As SurfaceContourLabelGroup


However, this doesn't work, as Visual Studio told me "Warning: Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated." 

I tried just saying: 


But that didn't seem to work either. How this class works and get it to add some contour labels to a drawing?

AutoCAD Civil 3D :: 2014 - Point Group (NO DISPLAY) Does Not Appear To Be Included

Dec 20, 2013

I just started work in Civil 3D 2014 and was going about creating different point groups for some volume calculations so I could create different surfaces.  I noticed after creating my first point group that the NO DISPLAY group could not been seen in the Prospector under Point Group.  Now in previous editions there has always been a NO Display Group so you can easily view your different groups.  Is this something they changed in Civil 3D 2014 or was the installations faulty?

AutoCAD Civil 3D :: Project Point Group To Profile View?

Apr 12, 2012

Project objects to profile view... got it. No problems selecting individual survey points or survey figures and projecting to profile view. Is there a way to project a entire point group to a profile. I have a point group created for the large number of points to be projected. Next I right click on the point group and click "select'. Then go to Project objects to profile view. Nothing...

This process works for the survey figures, but not the point groups! In prospector tab go to survey > figures then select CTRL + each figure to project then VIOLA' the whole group of figures are projected.

Is this limited to graphical selections only? If so, is there a workaround to generate a graphical selection set from the point group.

AutoCAD Civil 3D :: Station Offset Report By Point Group?

Feb 2, 2012

I am trying to use the Station Offset to Points report from the Reports manager. Currently, as far as I ca see, there is no way to select a group of points to include, either by point group or selection from the drawing.  There is only "Select All' or "Deselect All".  I want a report that will show the station, offset, raw or full description and elevation of a group of points related to an alignment/street.  I don't see that option.

AutoCAD Civil 3D :: Lighting Up Grips When Selecting Point Group?

Oct 5, 2013

when selecting a point group from the prospector tab, sometimes the point grips will light up and sometimes only the points will be only dashed.

Having the grips light up like that is very useful when viewing a region with many point groups.

How do I toggle this on and off?

AutoCAD Civil 3D :: How To Find Primary Point Group Using VLisp

Aug 30, 2013

When I use the AutoCAD List command on a Civil 3d Point, one reported datum is Primary Point Group.

I want to get at that information with vlisp, but when I vlax-dump a point, there is no mention of Primary Point Group. If that's a limitation of using vlisp, let me know, and I won't chase it. 

Maybe I have to go in through the point groups collection?

AutoCAD Civil 3D :: Same Point Group Are Imported Into Separate Layers

Oct 31, 2012

I am running C3D 2010. 

Somewhere along the line, someone in our office made our template import points into separate layers based on the RAW Description. I would like to un-do this. So far, I have deleted every point style & point label style except for 'Basic'. Inside of 'Basic', the layer is 'V-NODE'. However, some of my points are still coming in on layers like: 'V-Site-'(Raw Desc). 

I'm about to start from scratch on the template, however, I'd like to avoid that because of the array of styles that are in it.

AutoCAD Civil 3D :: Point Group Query Invalid With 2012

Apr 12, 2012

I'm using civil 3D 2012 for 2 weeks now. When I create a query to include or exclude points in a specific point group I get an error. It doesn't allow me to build a query with decimal number but only with natural number. 

Everything was fine with my old civil 3D 2011.

The problem is with civil 3D 2012? or maybe their is a magic switch somewhere to allow me to use decimal number?

AutoCAD Civil 3D :: Creating A Surface From Points?

Jul 30, 2013

I have a grid survey of points and I've entered these points into Civil 3D.  Now what I want to do is use these points to create a surface so that I can create a slope analysis of the surveyed area.  My problem is that I can't get the points into a point group.  

I have a generic grid (15 x 15) of points set up and I've only used a portion of them (defined by the dimensions of the site).  So I want to create a surface that includes all of the points that aren't set at an elevation of 0.

AutoCAD Civil 3D :: Cannot Remove Points From Surface

Mar 29, 2013

I have an "existing" surface built. But there has been some construction since my company surveyed the site. So, my surveyor went out and got the new points in the area of the new construction. I am trying to remodel the "existing" surface without rebuilding the entire surface. I have removed the old (demoed) points from the point group used to define the surface. But, the points are not being removed from the surface.

AutoCAD Civil 3D :: Extracting Points From A Surface

May 31, 2013

I built my surface by importing points directly, ie, not through the ribbon, so i have no points listed in prospector.  i have been editing the points (mostly deleting errant survey points) and would like to export the final data set.  The only step i found, was to show points in surface style, and then Extract Objects (of which i selected Points).

This seems to have no placed all the points into my DWG, but HOW do I export this files into a single text file??

AutoCAD Civil 3D :: Surface On Nearly Aligned Points

Sep 12, 2013

I have alignement of wall or embankment. I have existing ground including this corridor river. I have also CSV file with points (x,y,z). On my sketch there is drawn. Points present FDL (flow defence level) maximum level of river in case of huge rain or other things. These are almost aligned. I need to transform it (project) into alignment. I have to create profile of EG, FDL (based on this point) and then create new profile of height of wall or bank. What is the best solution for projecting this points. I tried with grading (distance and grade0%) I tried then with offsetting this feature line based on points and used it as breaklines. Created surface had holes.Even real is worst because alignment is perpendicular in same places to river.

AutoCAD Civil 3D :: Adding Points To A Surface?

Apr 24, 2013

I have created a surface with a point group.  I have a few points on the edge of my surface that need to be added to the surface.  I can add them to the point group, but when I updated my surface nothing happens.  The triangles don't extend to my newly added points and my profile of the area doesn't show a surface where these new points should be. the new points I want to add have the same properties as the other points in the point group, they are cogo points.

AutoCAD Civil 3D :: Import Survey Data Default Point Group Styles

May 3, 2012

When you use the Import Survey Data wizard it automatically creates a point group that goes to the top of the list. This used to be created with a standard point style and description, but something has changed and I'm getting a different symbol and label that I definitely don't want as the default. I would think that this would be controled by the CreatePointGroup settings, but that isn't working for me. I can't find any other settings that would override or control this.
