AutoCAD Civil 3D :: Contours Partially Vanish When Xrefed

Aug 3, 2012

I can stumble a bit, and have reasonably competent in the ACAD side of it.  but here's my issue: existing grade was created in a separate office (by a non-c3d guru) and the surface drawing was shipped up to the remote office. There's nothing in the drawing except the surface (created from GIS contours) and the contour labels. Layers for major and minor and labels are all on, not frozen, visible, and none are set to non-plot. (C-TOPO-MAJR, C-TOPO-MINR, C-TINN, C-TOPO-TEXT)

This file is XREFed into modelspace in a sheet file that has a half-dozen tabs, two to three vports per tab. In some of the viewports, not all by any means, either none of the contour lines show up, or only some of them do. There are no per-viewport over-rides, and all layers are on, thawed, and plottable. In the area where the contour lines fail to show up, the contour labels do.

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 :: Xrefed Cross Sections

Feb 29, 2012

I have created a drawing called xsec. I xrefed the corridor drawing into it and data shortcut the alignments in as well. I created sample lines and cut my cross sections in the drawing. Everything at this point looks fine.

The problem happens when I create a new drawing and xref the xsec into it. In this new drawing only the right side of my cross sections is showing up. I want to use this drawing for my sheet set rather than have a bunch of tabs in the xsec drawing.

AutoCAD Civil 3D :: XREFed COGO Point Markers Pick Up Color Of Current Layer?

Aug 7, 2012

We have survey files that we xref into our design files. In the survey files themselves, the points don't change color. When we xref them in, the point markers (only the circular node on the actual point, not the line coming off of it) take on the color of whatever the current layer is in the drawing, only fixable by changing the current letter and regenerating.

AutoCAD Civil 3D :: Contour Labels Vanish On Rebuild

Apr 9, 2013

2012. I have contours from a corridor merged into a full surface. I labeled the contours, then had to rebuild the corridor after the profile changed.

The contour labels all vanished and had to be redone. While surface contours work well for roadway corridors with few intersecting roads.  I am not finding them to be useful for parking lots.  I am thinking I will have to go back to the extract all contours from model and neaten them up for acceptable graphic presentation, then label them using the label line function and pray they don't change.  i.e. old LDD work flow.

The automatic outside boundary also does not work well when updating parameters and rebuilding.  The old fashioned LDD boundary from polyline seems to work better most of the time.

AutoCAD Civil 3D :: How To Smooth Contours

Oct 23, 2012

I'm drawing a topo and trying to figure out a way to manually smooth out my contours. I'm not talking about the little jagged edges that you can remove if you use the smooth surface option under surface properties but the big ugly looking jumps you see when contouring a relatively flat lot. In the ancient version of AutoCAD my company used the contours came in almost like splines and you could move the vertices around to make them look good. I know you can go in and delete some TIN lines and edit point elevations but that is very time consuming and I'm hoping there is a quicker way.

I know I can extract them into polylines but there are too many little segments to be useful. I've seen the SIMPLIFY SURFACE option and while that takes away some of the roughness it creates some as well. Is there some better option than extracting and then drawing a spline between the parts I want to smooth out? These contours don't need to be 100% accurate, I just need them to look simple, like if someone was drawing them by hand.

AutoCAD Civil 3D :: No Contours On TIN Surface?

Apr 25, 2012

My TIN surface either did not generate contours or did not display them on my drawing. I created and tried  surface styles of many contour intervals(from 0.5' and 4' to 2' and 10') without success. I made sure my contour layers on both the Style Dialog box Display Tab and Layer Properties Manager were turned on, still no success.

AutoCAD Civil 3D :: Breaklines And Contours

Nov 26, 2013

I'm having problems contouring in C3D 2014.

I'm using the command PL - polyline to create my break lines (Centerlines, top and bottom of curb)?.

 In this particular drawing the first point I click on is carrying the elevation throughout the entire length and yielding bad contours.

Essentially the bottom of curb on each side of the street should be the same elevation with a crown at the centerline.

Instead the elevations are about five feet different because the beginning point is around the corne at a point of tangency on a hill.

This has not happened in any other drawings and I've done them the same way.

I redid the breaklines with the 3DPOLY command and aside from a few minor edits the surface came out OK.

I've been reading about 3DPOLY command but have not found out too much about what the actual difference is between 3DPOLY and PL commands.

Seems like 3DPOLY is the way to go. 

I do not have too much experience with C3D 2014 and am making a huge jump from 2004 LDD. How to build 3D surfaces/contouring.

AutoCAD Civil 3D :: How To Get Simple Contours At Once

Sep 9, 2012

When I generating contour(surface) using Civil 3D it gives very complicated contours.Some times those contours cuts each other and have very strange shape.

I used to use SURFER software to generate contours.It gives simple contours.But I like to use Civil 3D because.

I attached SURFER contours and Civil 3D contours. I also attached AutoCAD file those who using older versing of Civil 3D.

I know how to smooth contours in Civil 3D but it does not solve my problem. You may say "You should  use commands like swap edge,delete line .

AutoCAD Civil 3D :: Computer Lag With AECC Contours

Mar 20, 2013

We have a total of three machine at our office that are running 64-bit Windows 7 with Civil 3D 2013. Two of the three machines have problems with drawings that include AECC_Contours. When you try and start a polyline or line the mouse will begin to jump and lag. As you move the cursor off of the AECC_Contours the mouse returns to normal operation. I have looked around throughout forms and have yet to find anything that relates to this. Also I have disable Aero within Windows, thinking that may have been the issue. All three machines are running the same version of Civil 3D with the latest service pack.

AutoCAD Civil 3D :: Contours Disappear In 2010

Nov 8, 2013

While working in a drawing with civil 3D points and a surface created from those points, once in a while the contours will disappear. The contours disappear during any number of different commands, so it doesn't seem to be linked to a specific set of commands. If we save the drawing, close it, and then open it back up the contours are there with no problems. Is there a fix for it beyond closing and reopening the drawing. We are using Civil 3D 2010 in our office, and all of the current updates.

AutoCAD Civil 3D :: Correcting Surfaces / Contours

Nov 6, 2012

Im working in Civil 09. I need to adjust the surface I created in order for the contours to be correct. Right now I'm interpolating point elevations to adjust the contours. I find myself adding lines and adding and deleting points. It's tedious. I tried changing the grid spacing to smaller one. It didn't seem to work.

AutoCAD Civil 3D :: Labeling Contours In Every Drawing

I'm running 2012. Is it still true that I need to label my contours in every drawing? I have a drawing that contains my existing surface (about 90 Acres). I have labeled the contours in that drawing. I then have a output drawing that the existing contours are a data shortcut. The contour labels do not show up.

AutoCAD Civil 3D :: Creating Surface From DGN Contours

Dec 10, 2013

This is the first time I have imported a .dgn file into Civil. The drawing contains contours lines with Z elevation data. When I create a surface using this geometry (polylines + some lines) the surface seems to be scaled in the Z axis by 12.

For example pline (from dgn) is at elevation 46' but the Civil3D surface is 552'

I assume this is a setting in the Surfaces dialog box, but I cannot find it.

Also the elevation field in Properties from the dgn contours is weird. For example, in one area the (pline) contours display -28', 26', -24', -22', -20', -18' in Properties but Civil3D interprets this as a downward slope - which is the actual field conditions. I don't understand the conversion going on here.

The geometry of the pline and contours generated from the surface seem to line up in a side or isometric view (see attachment).

AutoCAD Civil 3D :: Labeling All Of Surface Contours At Once?

Nov 6, 2013

Often I've found myself dealing with some pretty complicated surfaces that have a lot of nooks and crannies, and many of the contour lines are only in a corner of the surface or are small and closed, and thus when I find myself wanting to have contour labels on all of the contours, there's not really one line I can draw using the "Create Multiple Labels at Interval" option to ensure that every contour is labeled. Thus I end up doing "Create Multiple At Interval" with a few different lines intersecting contours, but I often end up hitting some of the contours multiple times and I get a mess of labels.

I haven't been able to find a way to automatically just multiple labels on all of the contours at an interval in one fell swoop, so I started trying to program one...but then I got stuck with that, too.

Does any built-in method of doing what I want to do, or do I need to continue pursuing a programmatic solution?

AutoCAD Civil 3D :: Stretching / Adjusting Contours

Oct 28, 2013

We are currently STILL in the transition from LDD to Civil 3D 2013.  Is there an easy way to stretch the contours within a surface without physically editing the surface.  Right Now,  I have a couple contours that have have spikes in them from lack of survey data.  The Problem is that if I don't change the contours, I have to show steep slopes between them which I would rather not do.

Do I have to keep editing the surface to try and resolve this problem or is there a way I can just stretch the contours?

Right now I resolved the problem by coping the surface, exploding it and putting the contours on a different layer so that I can stretch them as I see fit But this is not a time effective solution.

AutoCAD Civil 3D :: Surface Contours Do Not Print

Jul 24, 2007

I have a surface with 1' and 5' contours. In model space the surface behaves normally - I can select it, add labels, change the properties, etc.

But...I have several paperspace layouts and in some of them the surface is not 'selectable', it is visible but I cannot select the object (as though it didn't exist). It does not show up in the print preview or the actual plot either. (Oddly enough, the contour labels are selectable and do print out just fine...)

The paperspace layouts are pretty much identical (plan and profile sheets of a road). There are no layout overides of any sort as far as linetype, visibility, etc.

AutoCAD Civil 3D :: Only One PC Will Not Print Surface Contours

Ok we have 6 identical PC's all with the same drivers, same support paths, same plotter paths. Only one PC will not print surface contours. I can open the same file(s) on any other PC and the things print w/o issue. This one PC will not print the srf contours on only a few files. Most files there is no issue...

Quite odd that it's only one machine messing up with a few files that another machine has no issue with.

AutoCAD Civil 3D :: Cannot Select XRef Contours

May 15, 2013

I am looking for a way to make it so that I cannot select an xref.  I want it to sit neatly in the background and leave me alone when I'm trying to select things in the current drawing. 

I am trying to design roadways on a steep hillside and the contours are very close together such that whe I zoom out to the view the whole project, there is no space on the screen where there aren't several contours within my pickbox.  I need the contours on so that I can layout around the topography, but in order to select the centerline of my road without clicking on the contours, I have to zoom in really tight and then select and zoom way out again to manipulate the other lines.  It would really speed things up if the xref contours could not be selected at all.

AutoCAD Civil 3D :: Contours Disappear On Corridor Surface

May 14, 2013

I built a corridor, then corridor surface.  Then I changed the corridor onto a different profile.  I noticed that the contours at the end were going crazy: the new profile ended before the corridor and everything was going down to zero elevation.  So I went to edit my corridor region.  I enter the required station, and my contours disappear.

Observations so far:

If I set the end of the corridor region to 2+377.91 to  2+384.54 inclusive, the contours on the surface disappear.  The triangles and boundary still display, and the surface gives a Z reading when I hover the mouse over it.  If I set the region end to something above 2+384.54 or something below 2+377.91 the contours reappear.

My profile ends at 2+383.00, and I would like the corridor and the surface to end there too!
