Apr 16, 2012

i have some existing drainage pipe and structures in a base plan that i need to change the invert (which is the easy part) and the top elevation to the existing top elevation that does not meet the minimum presect in civil 3d 2012 is there a way to change these min. to match my exisitng elevation for example i have a catch basin invert is 15.45 top is 17.56 with a 18" rcp  the cover will be less than 12" and i need to change this.

AutoCAD Civil 3D :: Find Invert Elevation Or Top Of Pipe?

Sep 7, 2011

I'm creating pipe networks to represent existing utilities and am still a novice of Civil 3D. 

I am creating sewer laterals that need to connect to the sewer main that I have already created.  My problem is that I can't find a way to find out the invert elevation of the sewer main at the specific point that the sewer lateral will be tying in to.  I no longer have an alignment or profile for the sewer main and I hope that I don't have to re-create them.  I just want to pick a point on the pipe and have it tell me that vital information.  Is there any way that I can do this in plan view?

AutoCAD Civil 3D :: Removing Extra In And Out Invert Elevation From Labels

May 9, 2013

Is there a way to remove the extra (In) and (out) invert elevation from my labels? If the IN or OUT (I.E.) is the same there is no need to label them twice. So, can I remove them?  If you can remove them, how do you do it?

This is what I have

AutoCAD Civil 3D :: Point Elevation Takes On Elevation Of Snapped Object?

Dec 19, 2012

When I snap a point to an object, the point takes on the elevation of the object. I would rather the point's elevation stay as is.

-changing osnapz variable

-latest civil 3d service pack

A few weeks ago I did not have this problem but once my computer was switched to the company's global server and c3d was reinstalled the problem appeared. Furthermore (post switchover), when a colleage of mine prepared a simple test drawing with just a line and a point, he was able to snap to that line without the point changing elevation. When he sent that drawing to me and I tried snapping the point to the object, the same problem occured with the point taking the elevation of the line object. I suspect it is a system variable issue

AutoCAD Civil 3D :: Structure Table That Lists Both Existing Surface Elevation And Proposed

Mar 5, 2012

So we have to adjust the elevation of hundreds of drainage structures from their existing elevation to the new finished ground elevation.I know we can give this information within the structure label by adding a reference surface but we would like to produce a table with three columns:

Structure No.      Existing Rim Elev.      Proposed Rim Elev.

How to produce such a table?

AutoCAD Civil 3D :: Import Point File And Assign Elevation Based On Existing Surface

Apr 12, 2012

I have a bunch (hundreds, so manual input not an option) of X,Y points without elevation data that I would like to import into a DWG and assign an elevation that is based on an existing surface object.  Is there a way to do this for a point file? The command for inserting individual points would be the "Create points - Surface > Random" but I don't see a way to do this in a batch type method where i have my PNE formatted input file to just move the points to sit on the existing surface.

AutoCAD Civil 3D :: Network Structure Elevation Change?

Aug 22, 2013

I assume nobody has been able to create a parametric part used for storm pipe networks that can have the pipes attached to a point within the structure other than the insertion, or have the elevation read from a point other than the insertion.

With that in mind, we are trying to develop a tool that would allow us to pick a strucutre, and set its "rim" elevation to a point on a proposed surface that is not at the insertion of the strucure. I am decent with lisp, but have not attempted to gather info from random points on civil ojects.

AutoCAD Civil 3D :: Change Elevation Of Survey Point Within Drawing?

Aug 28, 2012

I'm looking to change an elevation of a survey point within a drawing. I can see where it is possible to manually unlock the points from the Survey Database to allow the user to edit the point. I'm not seeing a method or property in the API Help for 2013 to do the unlocking with code.

Also is it possible to convert a Survey Point to a regular Cogo Point through the code? Or do I have to delte the point and then recreate it as a COGO point? I think this will be my work around if the above doesn't work.

AutoCAD Civil 3D :: Unable To Change Number Of Decimal Places In Elevation Label

May 7, 2012

The defaul label style for the Elevation of points is set to 3 decimal places. We are trying to change the elevation display to 2 decimal places. We have tried the directions in the following discussion: [URL].......

Which is:


-->Drawing name
--->Edit Drawing Settings
---->Ambient Settings
------>Precision -> We modify from 3 to 2 decimal places.

It does not modify the display settings.



---->Label Styles
----->(right-click) Edit label styles
--------->click on the "..." (three points) button

(Open "Text Component Editor - Contents"

--------->Select Point Elevation in the driop down list.
---------->Precision: Set to 0.01
------------>Ok, Apply, etc...

This does not seem to work either.

AutoCad 2D :: How To Change Elevation Of Each Vertex On Polyline

Sep 1, 2011

how to change the elevation of each vertex on a polyline so that each vertex has a different value. The way I attempted this in the past was to click on polyline, click properties and give each vertex the required elevation. However when I looked back at the values I noticed that every vertex had the same value as the last elevation value entered. is it something to do with ensuring polyline is 3D?

AutoCAD Civil 3D :: TIN Surface At Zero Elevation

I used the Volume dashboard to cal volume so when I view the surface in object viewer or 3D I see my TIN volumes surface at zero elevation is this right? I think the reason is because they want us to see both surface so they are not on top of one to another.

AutoCAD Civil 3D :: Object Elevation Label

Jun 20, 2013

Any way to label the elevation of an object where it is picked?  For example, I'd like to be able to pick on the node of a feature line or 3D polyline (or any object really) and have a label placed that displays the elevation of the object at the point where it was picked.  This could appear similar to the surface spot elevation label, but instead of getting it's elevation from a surface, it would come from the object where picked.  

Alternatively, any way to create a label style, perhaps using the Note label, to display something like this?  I don't even care if it is dynamic or not, static would be fine.  However, I do need it to scale innovatively .  Tool Pac has a feature that does this, but the label is just a polyline and text that is not annotative.

AutoCAD Civil 3D :: Changing Elevation Quickly

Dec 16, 2013

I conducted 2 surveys on different days and somehow the second survey was off by exactly 0.9 (don't ask because I do not know). With the temperatures being -10C with a very high windchill. I said I would worry about it after the fact once I put it into CAD. 

So I am on to Civil3D 2014. I imported the 2 .FBK files and was wondering how to do an elevation drop of 0.900m for just the one survey quickly.

AutoCAD Civil 3D :: How To View Contours At Elevation 550

I have a surface with a bunch of contours. I want to view the contours at elevation 550. In Microstation there is a set display depth command. Is there a tool in autocad where I can view certain elevations.

I want to make layouts/viewports that are clipped to different elevations. For example I have a surface with 5' contours. I want to create multiple viewports on a sheet showing what each contour looks like at its elevation.
