AutoCAD Civil 3D :: FG Elevations At Alignment

Sep 12, 2005

. How to assign proposed elevation to layout alignment along each station?. I know there is a way in LDT to assign proposed elevations to s specific range of stations or the full alignment, under menu "profiles/ FG Vertical Alignments/Create COGO Points" I am looking for the same one in C3D.

2. How to add connecting alignment label and station in profile view. For example I have an main alignment and in-between lot of other alignments are meeting with this alignment.

I want to show in profile view of the main alignment the meeting alignment's name and the station it meets with?

AutoCAD Civil 3D :: Setting Alignment Label Elevations

Mar 27, 2012

Way to snap or drape the alignment (station) labels over a surface or bring them to the elevation of a selected surface.  I'd like to know how to do this if there is a way, so when I look at surfaces in object viewer I can get an idea of where problem areas are from the stationing labels.

AutoCAD Civil 3D :: Adding Profile Elevations To Alignment Labels

May 10, 2010

Is there a way in C3D to add elevation information from a profile to an alignment label? What I'm trying to do is add labels to an alignment in a plan view with elevation information from a profile design associated with that alignment at a particular station. For example, the note would read:

ALIGNMENT B
STA: 12+83.67
ELEV: 435.87

I can't figure out how to add any elevation data to the alignment note. I really don't want to have to create a section and a corridor surface, but that's the only way I can think of right now... and I'm not sure that would actually let me add a station and elevation in the same note in a plan view.

AutoCAD Civil 3D :: Data Reference Alignment Stationing Differs From Original Alignment

May 3, 2012

I using a data reference/shortcut to properly label an alignment in paperspace. However when I reference the alignment in and apply the labels the aren't the same as the original alignment that I am referencing. Is there a setting where I am supposed to apply a new beginning station.

Also it seems as though the stationing(distance) isn't even matching up 1:1 with the original drawing. For example in the original base drawing my alignment starts at 10+00 with the next PI at 14+76.98, but the stationing on the reference alignment starts at 0+83.33 with the very same PI being labeled as 1+23.08. So the very same distance is 476.98' in the real design and the drawing it's being referenced in, but the stationing of the referenced alignment shows it as 39.75 Units.

I've attached a screen of the beginning of the alignment.

AutoCAD Civil 3D :: Change Alignment Label Style Set After Alignment Has Been Created?

Jul 18, 2013

Using Civil 3d2012, Is it possible to change the alignment label style set after the alignment has been created?  For example, for an alignment that was created with alignment label set X - change the label set to alignment label set Y?  It seems like this should be pretty easy, I must be missing something obvious.

AutoCAD Civil 3D :: Alignment Style Vs Alignment Labels - PI Treated Differently?

Apr 6, 2013

I have a question on Alignment PI's. (Point of Inflection/Intersection)I have an alignment where some PI's have curves, others are merely hard bends.

Is there a way to automatically label the PI's even if they have an associated curve? (I'd like PI, PC and PT)Alternatively, can I only show markers at PI's without curves?

Launching alignment grid view/alignment entities,

I’m wondering if there is a way to launch alignment grid view/alignment entities (attached) without the need to first launching “alignment”? This dialogue box is quite essential in editing the values of radius, degree of curvature and deflection angle for the selected curve.

AutoCAD Civil 3D :: Alignment Begin Station Inherited From Another Alignment

Aug 8, 2012

Can I inherit the station from one alignment as the begin station for another alignment?

For example. Alignment 1 is 1000 ft long and starts at sta 0+00.

At sta 8+01, Alignment 2 begins and goes off in another direction.

I manually enter 8+01 for begin station Alignment 2. Life is good. Still in the design stage, and customer needs to modify Alignment 1 to avoid something. Now Alignment 2 intersects Alignment 1 at sta 8+15, but same N/E coordinates.

I manually enter 8+15 for begin station Alignment 2.

It would be better if Alignment 2 could inherit the begin station based on the new stationing from Alignment 1.

AutoCAD Civil 3D :: How To Know Surface Elevations

May 3, 2012

In C3D 2012, when I needed to know what elevation a surface contour was at, I simply hovered my mouse near the point in question and a small window would tell me what elevation my mouse was hovering at. Now, in 2013 I am trying to do the same thing but the little window only has the name of the surface and no elevations. So, how am I supposed to know surface elevations on the fly? Is there some setting to turn that back on?

AutoCAD Civil 3D :: Determine Elevations Along Slope

Dec 3, 2013

I need to project a surface/grading (or something of that nature) across my berm and have it intersect with the inside bank. This is better explained if you see the attached image. In the plan view you see 4 featurelines. Outside TOE, outside TOB, inside TOB then inside TOE. I need to project the outside TOE across the berm (shown in the section view) then create a new featureline where the line and inside slope of the berm intersect. Note that all the elevation shots vary as does the widths across the berm. What's the best way to do this?

AutoCAD Civil 3D :: Point Groups Elevations

Feb 28, 2013

I have two different point groups that I am using in my drawing.  One is from a survey done a few years ago and the other is from one that I did just the other day. 

I don't have a problem inserting the points or whatnot, but the issue I am having is that when I click "Datum" to adjust the elevations of my new point group (to make my benchmark 100.00'), Civil 3D alters all of my points; including the ones from the older survey. Is a way to adjust elevations to only one set of points.

AutoCAD Civil 3D :: Survey Figure With Bad Elevations?

Jun 29, 2012

I have a survey figure that no matter what will not come in with the correct elevations, its a spline (continous) curve that the elevations get blow up on.

Only thing I can think of is the when it starts to interpolate the curve it cant get the elevations correct, this only happens in the curved area, once it goes tangent everything goes back to normal.

AutoCAD Civil 3D :: Feature Line Elevations

Mar 25, 2013

We are running Civil3d 2012. When converting a line or 3d poly to feature line, or just creating one it adds elevation points where it crosses surface breaklines even if you do not assign elevations. We want the feature to just have 2 elevations. The beginning and end. Is this a bug? Or is there another setting somewhere?

AutoCAD Civil 3D :: Elevations On A Curved 3D Polyline?

Aug 13, 2013

I am working on laying out data for some survey crews along the centerline of the road.  I have a BC and EC elevation, but the vertices along the CL are at different elevations, which were the original elevation of the poly line before being transformed into a 3D polyline.  Is there an easy way to make the full line follow the slope from BC to EC other than manually shifting the vertices?

AutoCAD Civil 3D :: Delete Zero Elevations From Surface?

Feb 1, 2013

I graded a commercial site with mostly feature lines. I added points where I needed them to get everything to work. After modifying my surface, I suddenly have zero elevations randomly throughout my site. They don't make any sense why they appear. Some are just added to my drawing and others are existing points that were changed to zero. I can go to a back up drawing from a few hours ago and redo some grading, but I would like to know if there is a way to just erase zero elevations from the surface. I remember LDD was able to create surfaces ignoring elevations below a set elevation.

AutoCAD Civil 3D :: Elevations Change During Insertion Into Drawing

Jun 21, 2013

I have imported a survey file.  When I insert the points into the drawing, the elevation changes to something that isn't even recognizable.  When I view the point in the survey tab, the elevation is correct, when I view the point in the prospector tab it is different.

AutoCAD Civil 3D :: Can't Edit Elevations Of Feature Line

Apr 19, 2012

I Created a Feature Line from Objects (a polyline).  I added it to Site 1, gave it a name, layer.  Do I Assign elevations during creation (conversion options)?

I set the Elevation to 8.5  (NOT From surface)

Then I go to

Modify Feature Line -

Elevation Editor.

Why are the elevations locked?  I want to set them.

AutoCAD Civil 3D :: Extract Elevations From Survey Drawing

Sep 24, 2012

I've been sent a survey drawing with elevations. The format is a block, but it's not a named block. Each entity has it's own block name. So, I'm having trouble getting at the elevations. I can't seem to export and get the elevation or Postion Z.

I've tried exploding these blocks, but all I get is a couple of polylines, and some text. Useless. I've attached a sample drawing with a couple of these points.

AutoCAD Civil 3D :: Profile Bands - EG Elevations Blank

Jun 28, 2011

Civil 3D 2011: 

I have 7 roads in my drawing and all of the profile data bands except one are correct.  We first started with an overall profile with the EG created from a surface and the FG created by drawing in profile, then created multiple profile views.  The only thing wrong with the one road profile is the data band is not showing the EG elevations.  The strange thing is under Profile View Properties - Bands Tab, Profile 1 is set to EG and Profile 2 is set to FG, so it recognizes it is there and is also shown in the profile, however no elevations.  I have tried recreating the multi profile views.  Attached is a screen shot to give you a visual.
