AutoCAD Civil 3D :: Assign Elevation To Cogo Points By Snapping To Entities?

Jun 17, 2013

Can you manually create a new cogo point and have it pick up the elevation from a 3D entity that you snap to?

I found this thread from 2010 that says no at that time.


Is this still not possible with C3D 2013?

AutoCAD Civil 3D :: Cogo Points Snapping To Z Value

Feb 1, 2013

I was able to move Cogo points onto an existing line or polyline, and retain their existing Z value, rather than changing to 0.00 of the height of the poly line/line.

Is there a variable to change this? Thought it might be "OSNAPZ" but thats already set to 1 and this is still happening.

AutoCAD Civil 3D :: COGO Points Not Displaying Elevation Properly

Jul 1, 2013

I have a rather odd situation.  I have input a small table of survey points (we don't have access to a data collector, so it had to be manual).

I have a properly located and back-sited setup, with all of the points located in 3 dimensions.

The Northing/Easting/Elevation data is calculated and displayed for all of the points in the "observations" table accurately.

Every point has the same display/labeling properties/settings, but only 2 points properly display the elevation as calculated.

The problem seems to be that the points aren't accurately retrieving the Elevation from the table.

For some reason, in the “Properties” dialogue for the points that display properly, the “Point Elevation” field actually contains a number; whereas the points that don’t, the same field reads “*PROPERTY NOT SET*”.

This makes no sense, because in the table that defines the points, the elevation is accurate for all of the points, and I can’t find a difference in the table- or in the point properties- between the correctly displayed points, and the ones that are missing the elevation label.

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 :: Create Feature Line By Snapping To Cogo Point Node

Oct 7, 2013

I think this issue started with SP2. I don't remember having these issues in SP1 and earlier.

Create some COGO points at varying elevations.Start a new feature line.Use "node" object snap and pick your first cogo pointIt does not pick up the elevation of the point (it used to)Now draw feature line segments to a few more cogo points entering the elevation each time.It does not pick up the elevation of the point (it used to)Now switch to Arc mode and snap to a few more cogo points.It does correctly picks up the elevation of the cogo points (like it used to)R.K.

AutoCAD Civil 3D :: Converting Points To COGO Points Naming?

Oct 9, 2012

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.

AutoCAD Civil 3D :: Cogo Point Elevation Precision / Display From LDD

Oct 10, 2012

I'm trying to determine if it's possible to take a 09 LDD Companion drawing in which the elevations for many points have been moved AND/OR rotated (to align with roadway), and not only convert these to C3D, but also have them transferred along with the move/rotate information.  We're talking about a mile long stretch of roadway and the project is 6 years old (i.e. no C3D when it was originally done). 

The problem is that there are a ton of ground shots that need only be shown to 0.1 precision but are shown to 0.01 precision.  LDD was not able to assign an elevation precision to groups of points, only all cogo points together, which meant we had to explode certain groups of "soft shot" points once they had been inserted at the desired precision. 

If there's no way to do what I'm asking, it's no big deal for this case since the higher precision can be easily rounded to the lower by the viewer (better than the other way around).  But as I am the only one on C3D and have been for the past 2 and a half years, we will likely face this monster again several times over with other drafters' projects and I'd like to have a best practice in place if we need to go the other way (extracting 0.01 precision from 0.1 precision).

AutoCAD Civil 3D :: Override Cogo Point Elevation Label With Text

Dec 17, 2012

How I would replace the Elevation label on a point with Alphanumeric text on certain points in a point group (or if it can be done at all)

Some background info:

I work with site diagrams that have monitoring wells and each one has a groundwater elevation value that gets updated every year according to field data. Our current setup is that the monitor well name and elevation values are displayed using point labels and looks like:

x 12-1 (Monitoring well name)

   788.432 (Groundwater elevation value)

However, sometimes the monitoring well is dry and we need to display 'DRY' instead of a numeric elevation value. Autocad won't let me put 'DRY' as an elevation because it's not a number. Is there a way to override this, or somehow make the label display 'DRY' if elevation of 0 is entered? 

Another use to overriding point label elevation is that sometimes the groundwater elevation that we get from the monitoring well is so far off from the general contour pattern that we will put the elevation value of that well in brackets such as (788.432) and indicate that this means the elevation was not included in the groundwater contour flow map. 

Is there a way to do this override, or is there another method I should be using to label my monitoring well elevations? I know I could just MTEXT everything, but that's double the time to update the point elevations for the contours and then updating the mtext to display the numerical elevation values.

AutoCAD Civil 3D :: COGO Points Description And Styles

Sep 10, 2012

How to set a default point description to match the point number. I need to match the point number and the point description as per below:

Point # = 1 - Description = 1Point # = 2 - Description = 2Point # = 3 - Description = 3and so on.

Is there a quick way to add this description once the points are already created?

Also, it seem I can't make the default style and label to work. I edited the Feature Setting on the Setting tab of the Toolspace and I made sure there's no child override. When I open the point creation menu, my default styles are there (grayed out), but when I create the points, they pick up another style and another label style.

AutoCAD Civil 3D :: Cogo Points Plan Readability

Sep 5, 2013

My delima is regarding cogo point readability. I'm used to LDD so this may be the issue. I set a cogo point but I want it to stay in the same orientation. if I use orbit or dview the cogo point data reorients (rotates) to line up horizontally. I would like the data to remain as set originally. I tried changing plan readabilty in label styles but when I drag the point it rotates to the current view orientation. Is there a way to control the rotation once dragged so it does not reorient if I change the orbit or dview?

AutoCAD Civil 3D :: Cogo Points Rotated In Paperspace

Oct 1, 2012

I have a dwg that looks great in model space, however I created a couple paperspace layouts and then used Align Space to rotate to those views. The problem is that my point label style rotates the point labels based on the align space rotation.

I looked into the point label settings and changed the orientation reference to the World Coord. Sys., but it does not make the points rotate correctly. (world reference is the goal).

AutoCAD Civil 3D :: Creating Blocks From Cogo Points?

Feb 11, 2013

We are in the middle of upgrading from LDD2008 to Civil3D2013. This is a 2 part question. Since there are NO point labels similar to Poiint labels in LDD2008. It is making cleaning the elevations up very teadious. With point labels that are just Mtext. I would rotate 1 label and then match properties to rotate the rest and then jiust more the elevations to make them readable.

How do you all deal with cleaning up the elevations?  Is there a way to match proprties as far as the rotatiion of the points? or do you Create blocks from Cogo points?

So, I starting playing with the Creating Blocks from Cogo Points. This creates a block with attributes similar to the way Softdesk treated points back in the day. I ran into a couple of issues. 1 being, it rounds the elevation to 3 decimals places.

When it creates blocks from the Cogo Points some of the blocks are giving me 0.000 elevations for points that had actual elevations.

AutoCAD Civil 3D :: Automatic Hyperlink On COGO Points

Jul 1, 2012

As survey data collectors now come with cameras intergrated, it would be very useful to be able to have a way of hyperlinking the imported survey points to the images. Images are normally named by the survey point number that they are associated with.

Can Civil3D import points and automatically have the hyperlink field of a COGO point populated?

Can this be achieved through the survey database? Or maybe via a point-file with UDP's?

This is a fantastic option, but I have a problem the whole drawing is rounded to two decimal places.

But when I execute create block from Cogo points he round heights on all points to three decimal places,where the third decimal is 0.

Example height is H =198.36 after H=198.360.

AutoCAD Civil 3D :: Copy Cogo Points From One Drawing To Another

Mar 11, 2011

I would like to copy cogo points from one drawing to another, keeping both their layer and user defined properties.

I can:

1. Do a copy and then paste to orginal co-ords. This keeps the layers but loses the UDP's.

2. Export the points to a csv and import into new drawing. This keeps the UDP's but loses layers

3. Export to XML. This loses both Layers and UPD's

I don't have a desc key file setup for the codes on these pts so this is not an option.

AutoCAD Civil 3D :: Cogo Points - Object Naming Defaults

Jun 19, 2013

I'm not finding where to change the default Description for Creating Cogo points by the Create Points-Alignments>At Alignment Geometry method

The last characters PC, PT RP etc. seem to be controlled by the Drawing Settings>Abbreviations but the Alignment name and stationing is what I'd like to eliminate from the description if possible.

Almost seems hard coded but hopefully I've been looking in the wrong places.

The descriptions are coming in like the caption whether I select Raw or Full description option.

In command settings for Point>Create Points>Points Creation>Prompt for descriptions>Automatic - Object is what I'm using.

What I'm hoping to accomplish is just PC, PT RP etc for description without the find / replace edits I'm currently doing in the exported ascii files.

AutoCAD Civil 3D :: Cogo Points Explode To Block Reference

Oct 7, 2013

I got a survey that has hundreds of cogo points. I need to bring this into a mapping dwg but not as cogo points. What's already in the map file is block reference (trees, power poles, signs, etc.). When I explode the cogo points (select all) they turn into 1/100th of the size (although the Properties scale hasn't changed). If I explode one by one, they are fine. how I can get these cogo points into the map dwg as block reference at the correctoriginal size?

AutoCAD Civil 3D :: Projecting COGO Points To Profile - Style

May 17, 2012

I have projected Civil 3D COGO Points projected to a profile.  I simply want to display the Civil 3D Point Number for each point in the profile. 

In the Profile Projection Label Style, the only field in the text editor that displays this point number is the "Source Object Name.  This shows up as "CogoPoint 124" for point 124 (see attached).  How do I make this simply say the point number ONLY, i.e. "124"?

It would be nice to program the label style to display this field, yet delete the first 10 characters of "CogoPoint x", so it only says the point number, "x"
