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.
I was given a file with LDT points in it that show point#,Elev, Desc. When I convert the description turn into a number. How does that happen and how can I change it to convert the description correctly?

I had command shortcuts created in 2012 (in the acad.pgp file) for AECC commands like drawing feature lines, trimming feature lines, etc. My shortcut commands that began with AECC aren't working in 2013, perhaps becasue these now pull up a dialogue boxes before the command is shown in the command window? How I can get keyboard commands to work for this? I'm lost now looking for all sorts of buttons!
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.
i'm exporting a surface from 2013 to be used in 2010 for presentation. works great but the contour interval is not the same as the surface i'm exporting. working in 5/25 contours...xml import comes in with 2/10 contours. looked for a setting but can't seem to find.
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.
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.
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.
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.
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.

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.
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).
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?
trying to create a model from existing polylines (at elevation). I have created a surface, went to definiltion, drawing objects, but there is no "polyline" option there. I must be missing something. How can I create a c3d model from existing polylines?
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.
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.
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.
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.
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!
I have created surface contours from points, but I just can't sem to figure out how to decrease my midordinate distance. I know I can go all old-school and explode the surface then make a new one by defining contours, but there has got to be a better way.
I have defined 3 user-defined contours for various elevations in my pond. I would like to disply them differently from one another, so I set their display styles in the analysis window where I created them. Unfortunately, the are only displayed per the settings in the surface style which is 1 - not what I want and 2 - all identitical. I have tried various settings in the surface style, but the contours will not display the way I have selected in the analysis window.
