I have a few points within an area of 2m x 2m and I will like to create contour lines. At the moment I can only produce models with shade difference.
Thge contour command does not accept sub 1 metre accuracy (putting 0.1m does not work).
Is there something I can do?
I encountered a problem while creating contours from the points. what actually is the problem with the points or tell the steps once again that would be great. I'm attaching the points file.
View 9 Replies View RelatedI 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 just installed AutoCAD 2010 Civil 3D on a 32 bit Windows 7 machine. When I open a dwg sent from a surveyor I can see and manipulate all the linework, contours, points, and SRF breaklines in the drawing. When I proceed to save the file to my computer and reopen it, the contours and points disappear; however all linework and surface breaklines remain. The two files that I have been working with were saved originally in 2004 and 2007 format. I have tried saving to their respective versions but that has not worked.
The only way that I have been able to retain these objects is by first exploding them and making them into a block and later inserting them into the other drawing. If I try to make them into a block without exploding them they also disappear.
Is there a way to retain all drawing objects directly from saving?
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 have a large surface (over 1.5 million points and 20 000hectares)
I need to get a point file .csv from the TIN to be able to use it in another program.
-so i've extracted the points from my surface, but they are Autocad points.
-next step is to convert them to civil 3d points.
-I can not select them all when converting them or my computer crashes.
-so i select about 25 000 at a time, the converting takes roughly 10 minutes.
and i have over 1.5 million points to do.
how can i speed this up.
will more ram useful?
there is a way to convert land desktop aecc points to cogo points and use the full description?
I do not have access to the ldt files nor to the Descriprion keys file. It would be nice if there was an option to preserve full descriptions when converting (that would be just too simple).
I have recieved a file with many points and would like to convert them into COGO points in Civil 3D. The problem is; I would like to keep the hole ID's as I convert, I've made a few conversions and lose the hole ID every time (not showing in Name or Description). Is there a seting I am missing to keep these? My aim to to organize the COGO points in different point groups.

I can't seem to find a way to do that other than perhaps re-importing the specific points as control points and overwriting the existing ones.
View 2 Replies View RelatedI have a project that was started by leaving all the survey data inside the "All Points" group. So, I'm concerned that when I enter my as built survey points, that even if I put them into their own group, that the original surface will still look at them and just rebuild to my asbuilt data, effectively cancel out the purpose of the asbuilt survey. Will this happen?
I want to take the original points and put them into a group of their own, but I don't know if that will affect anything or not? I have several wetlands already designed on that surface with volume calcs already done too.
What should I do?

View 3 Replies View RelatedI have two locations marked by steel stakes on my land that are also shown on a CAD drawing. The CAD drawing is two dimensional; however, contours are shown. I have physically measured distances between these two known points and numerous other locations that I wish to plot on the CAD drawing. I could always print the CAD drawing to scale and plot the new points on the CAD printout by using the two known locations, a compass to draw arcs and locating the new points by where the arcs intersect. I am sure there is a much more efficient way to plot these new points within the CAD program itself. I have just started to use CAD;

View 2 Replies View RelatedI'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.
I have added contours to my surface (the blue lines). For some reason the surface generated contour (the orange line) is jumping across the contours I've added.

View 6 Replies View RelatedI'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 want to color fill between contour lines. Most of the plug-ins I have tried only color the actual contour lines. Some of the large stand-alone packages say that they do it, however most are beyond my maker financial reach.
So my queries are: can this be done within any AutoCAD package? Are there any known plug-ins that can do this?
Or will I have to commission a customized plug-in. The image below is an example of the color fill required.

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.
View 6 Replies View RelatedWhile 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.

Is there some sort of quick selection I can use to select the elevations I need to delete?
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.
