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 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?
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).
I am creating a surface from polylines and the surface is not being created per the what the polylines represent. These are simple 5:1, 3:1, and 3.5:1 slopes. The surface wants to create curves instead of straigtlines (see attached).
The engineers at my company digitize proposed contours in a drawing and then they want me to create a surface out of the contours....the contours usually are 2 foot contours with areas that the software tends to translate based on the contours that I selected to create the surface.....I then usually need to create a profile, which does not look accurate compared to the contours, such as low spots etc...............
My question is since the engineers at my work do not how to use the software, and I am not an engineer, making the profile look a certain way sometimes needs to be tweeked by me.... How to alter the proposed surface?I am pretty sure that feature lines cannot cross contours that I have selected to create the surface?
I have created 2 surfaces of a matierial that is buried, using drill hole data. I have a surface for the top, and then a surface for the bottom of this material. I then created a 3rd suface comparing these 2, creating an isopac contour showning the thickness of the material. My question is this:.....is there a way to make the zero (0) contour show up? I have a .5 contour interval, but 0 doesn't generate. Could i be missiing something in the settings?
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 grid survey of points and I've entered these points into Civil 3D. Now what I want to do is use these points to create a surface so that I can create a slope analysis of the surveyed area. My problem is that I can't get the points into a point group.
I have a generic grid (15 x 15) of points set up and I've only used a portion of them (defined by the dimensions of the site). So I want to create a surface that includes all of the points that aren't set at an elevation of 0.
I created a Description Key called "EP" and it will land in a "S-PTS-EP" layer automatically.
I then created a Description Key called "NEW EP* " and created it to land in a new layer called "S-PTS-EP-NEW". But, when I manually create a point called "NEW EP" or "NEW EP BC", it does not land in the "S-PTS-EP-NEW" layer.
Is there some switch I need to turn on or is my description not complying with some naming convention?
I have a number of 3D polylines that where exported from SDF previously created. They have numerous vertices, each one with a given elevation.
How can I create/highlight the higher and/or lower point in each 3D polyline??
A different solution would be automatically breaking these polylines in slope changing points (i.e. high or low points).
I understand that i can create points according to slope or elevation, but it has to be done manually, each poly at a time, and by tipping numeric values that i am sure that a powerfull software (as Civil 3D is) is able to calculate using the drawing information.
I am building a surface and started looking at the triangles and found that some are going to non-existant points. I have unfrozen, checked, etc. all of my points to make sure they are not in the drawing.
I have a problem about creating feature line. When I want to create feature line between two red points, another point come into being by itself (blue point). If you look at the file I have attached, you will understand well what I want to express. I cant make any changes on this point. I cant delete, modify etc.
I have been given a survey on AutoCAD which was orginally 2D with the levels written in text next to it. I changed each point (690) to include the level in the Z-direction. I am trying to calculate volumes of topsoil removal and then cut anf fill volumes.
So I opened up Civil3D in metric template and imported my drawing as I have not been given a ddata file with the co-ordinates. Unfortunately I am having trouble creating a surface between the existing points.
We are in the middle of upgrading from LDD2008 to Civil3D2013. This is a 2 part question. Since there are NO point labels similar to Poiint labels in LDD2008. It is making cleaning the elevations up very teadious. With point labels that are just Mtext. I would rotate 1 label and then match properties to rotate the rest and then jiust more the elevations to make them readable.
How do you all deal with cleaning up the elevations? Is there a way to match proprties as far as the rotatiion of the points? or do you Create blocks from Cogo points?
So, I starting playing with the Creating Blocks from Cogo Points. This creates a block with attributes similar to the way Softdesk treated points back in the day. I ran into a couple of issues. 1 being, it rounds the elevation to 3 decimals places.
When it creates blocks from the Cogo Points some of the blocks are giving me 0.000 elevations for points that had actual elevations.

I am trying to set several hundred points along polyline verticies with the point number starting at 5000. There are no other points in my drawing, yet everytime I start the process, it begins at 1. I have set 5000 at my Next Point Number under Point Identity in the Create Points toolbar. I have also verified that the 'Save Command Settings" is set to yes under the 'Commands-Create Points'. We cannot get this to behave as desired.
I am having some trouble creating a TIN from a point layer in Civil 3D 2011. Would the best course of action be to extract the points from the drawing and creating a surface from there, or is there a way to create the TIN around the existing points in Model space?
I'm much better versed in AutoCAD, but excited about furthering my understanding with Civil3D.
I have a Drawing "A" that is the source drawing containing the existing ground surface, topographic linework and features, and points in the Survey Database which are under the Survey tab.
I have a Drawing "B" that is the source drawing containing the Design alignment and profile with references to the data in Drawing "A" such as the surface.
If I create additional points for survey stakeout purposes within Drawing "B", will it automatically be included in the survey database in Drawing "A" along with all the other points or is there some procedure in order for me to continue adding additional points into the database from Drawing "B" or any other drawing that references Drawing "A"?
Is it possible to create manual points from a cross section.
For example, I want to create a surface from a sketched (hand drafted) proposed cross section by clicking on the different points on my cross section and having a point created in my plan view.
I am working with an ancient engineer who swears by hand drawing data into the cross sections, and then wants me to produce proposed contours based on this data. I am trying to get out of writing down the Station, offset, and elevation, and then manually creating points and having to type in the offset and elevation again.
Stuck on Civil 3d 2011 (until the end of this construction season)
I am using Civil 3D 2012. I know how to label a line with bearing and distance. What I would like to do is make a table with these bearings and distances referencing the point numbers. For instance, I have a new ROW line that starts at point 1000 and changes direction at point 1001 and changes direction at 1002 and so on. I need a table that shows Points 1000-1001 is ___ Bearing and ___ Distance.
The lines are not parcel lines; they are only line segments.
I'm working with both Carlson 2012 and Civil 3d 2012 so this could apply to either one.
I have a set of caissons that were shot on separate days, and they started in the middle when they shot them in. I wanted to create a coordinate table, with the points listed from the northernmost point to the southernmost point. I had thought there might be a way to create a table with dynamic input, where I could pick the points as I go along and have the information entered as I pick.
Is there any way to renumber the points via drawing a polyline connecting them, starting with the one I want as #1 and ending with the last one?
I created a volume surface between the as-built and design surfaces, now I would like to show the points that display the cut/fill depths between these two surfaces. I tried modifying the surface property of that volume surface but doesn't seem to offer what I want.
I am creating a corridor with custom assemblies on two alignments. the alignments are not parallel and graded independently.
Between the two assemblies I would like to fill from one assembly to the other with a dynamic link. I can't do this as a target to featureline etc as it is within the same corridor. We have created the link with a target but this was done by creating a non-dynamic featureline from the corridor and using that as the target. This is obviously not great as far as keeping the corridor dnamic is concerned.
So I would like to customise a subassembly to allow it to target a marked point on an adjacent assembly.how the SAC tools (Get marked poinit or set marked point etc.) can be used to do this. The help file is less than useful. I am still on 2012 and dont have access to the 2014 SAC yet but will do shortly.
