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 :: 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 :: Create All New Existing Surface Over Existing Ground

Sep 28, 2012

I'm trying to create an all new existing surface over existing ground. I have a TIN surface of the EG, and I have drawn overlay splines that describe the new surface, but how to go about creating that design surface.

It is a compound surface, open on one end and closed all around on the other, somewhat like a half of a football stadium, but with an irregular upper edge because I am needing to figure out cuts and fills to manipulate the EG into this new surface without costly major terraforming. There is about 40-50' vertical elevation between the "field" and the upper rim with a generally constant 7-10 deg. slope all around. I'm just at a loss to figure out how to approach this project, and am quite new to Civil 3D.

AutoCAD Civil 3D :: Composite Surface Of Existing Surveyed Contours As TIN Pasted Into Existing Aerial Contours

Nov 15, 2012

Some background: We have a composite surface of existing surveyed contours as a TIN pasted into existing aerial contours that we received from a client.  We used polylines to generate our proposed contours, and then generated a proposed surface from that.  We've made a blank surface, pasted in the existing surface, and are trying to paste in our proposed surface...  only the existing contours outside of the proposed suface no longer line up correctly once we do.

We've tried applying the method laid out here: [URL] ........ (and the link referenced in the bottom) but are still having trouble getting the surface to work.  We've tried offsetting as little as 0.25' and as much as 5' with the feature line draped over the existing surface, but it seemed that the greater the offset, the greater the discrepancy.

Just to make sure we even tried that correctly - should the breaklines that we add be standard or non-destructive?  (I've tried it both ways with little success either way, so I don't know if it matters much in this instance, but perhaps for future reference it would work.)

I've attached a screen shot of our surfaces.  The pink and green lines are the proposed contours, the white dashed are the existing.  The outer red line is offset 0.25'.  As I've mentioned, we've tried offsetting various amounts with decreasing success.

AutoCAD Civil 3D :: TIN Surface At Zero Elevation

May 22, 2013

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

Dec 28, 2012

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.

AutoCAD Civil 3D :: Surface Elevation Labels

Jun 26, 2013

I have a drawing that someone else created that has a spot elevation label for a surface. It labels the surface (PAD) then automatically subtracts a set distance for another elevation (GFE) and adds a set distance for another elevation (FFE). After doing some research, it looks like it was created with an expression?

I have two questions:

First, where to go to get a better understadning of this? I'm not familiar with expressions.

Second, where can I find the expression in drawing to make an edit to the set distances. I can remove the GFE/FFE as they are separate components in the label style, but I don't see where to modify the distance it adds or subtracts.

AutoCAD Civil 3D :: Surface Analysis By Elevation?

All of the other analysis settings for direction, slope, and slope arrows allow me to input the nuber of ranges I want, but I need the elevation analysis.

AutoCAD Civil 3D :: SHP File Elevation Is Being Truncated

Dec 14, 2012

I am importing a Gis (2007) shp file into C3D 2013 (Attaching Query and everything else) and everythings seems to be working.  However, I get an elevation of 3 for all contours (Even before the Query a 3 feet elevation is depicted in the properties windows).

The only reason behind this, that I could think of, is that C3D is not reading after the 3.***** in the dbf file.

AutoCAD Civil 3D :: Super Elevation With No Curves

Jan 24, 2011

I'm working on a runway in Civil 3D 2011. I want to transition cross slopes along the runway. i.e. 1.5% for sta 1+00 to 10+00 and then transition into 1.0%. I thought super elevation would be the best way to do this (I dont want any actual super elevation, just transitions in cross slope). When I select the alignment and "Calculate/Edit Superelevation" i get the following message in the commanding line:

"_AeccCalcEditSuperelevation No superelevation data has been calculated for the selected reference alignment." It does not bring up the wizard.

My runway alignment doesn't have any curves and I'm thinking that's the problem. Is is possible to create super elevation without curves?

So far it will only let me use the SE for 4% local roads and I have to edit it using the SE layout.
