AutoCAD Civil 3D :: Elevation Design Value Is Greyed Out

May 31, 2013

I am pretty new to subassemblies and corridors and I think I have the jist of it but I have a few questions.

How do I lower stations of my corridor? I am making a grassed waterway and my corridor seems just ride on the surface.  I get to the parameter editor but the elevation design value is grayed out, so I can't change it.

AutoCAD Civil 3D :: Super Elevation Corridor With ETW Design Profile

Aug 15, 2012

I've got a highway project for which I'm modeling the corridor but the design profiles given to me are for the right lane top edge (ETW) and not the centerline (crown).  This is an undivided planer roadway with a typical 2% cross-slope.  How can I use that profile for the right edge to run my corridor?  I can't seem to get the corridor to use the super table that is attached to the centerline when I use an offset assembly.  Is an offset assembly the right way to go with this design?  

What I've done just to get going is to take that right edge design profile and draw it in my centerline profile view, then lower it 0.24' (which is my 2% normal cross-slope for a 12' lane) and then use that as a centerline profile and let my normal super assembly and table data control the corridor through the supers.  So far that is working--but is there a better way to do this?

AutoCAD Inventor :: Split Greyed Out Design Tree?

Mar 19, 2013

This just happened to me this morning, I split a part into a multibody part and as soon as I did the split, the entire design tree got greyed out. It doesnt matter if I have only one body visible or both of them, the tree stays greyed out. I can still edit features but its annoying to not know what is on and whats off. I opened a new file mocked up a quick part with various features performed a split and same results.

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 :: Edit Profile Geometry Greyed Out?

I have a strange thing that all of a sudden started happening. If I Rt-Clk on a surface on a profile and select Edit Profile geometry, the dialog box comes up, but almost every option in there is greyed out!

This is not drawing-specific, not is it machine specific.

AutoCAD Civil 3D :: Linework And Text But Not Blocks And Leaders - Greyed Out

Dec 11, 2013

When I draw new linework and text it shows up greyed out, even though it should be showing up full tone.  Curiously, blocks that are inserted on the same layer as the linework and text come in full tone.  

The attached image provides an example of what's happening (it's difficult to see the greyed out text reading "TEST", the leader, and a sawtooth section of polyline). 

More info:

Xrefed drawings are displayed at full tone.

Linework from earlier sessions are displayed at full tone - this is only affecting new work.

This happens only in this drawing.  

This happens on different sessions of C3D (i.e. different computers). 

This happens on when drawing on any layer.

The layers are unlocked.

This occurs in both model and paperspace. The drawing has been audited (no errors were found). Everything prints out properly. 

I suspect there's a variable that deals with visibility has been inadverdantly changed in this particular drawing.

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 :: 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.
