I am trying to add points into a surface. I have done this before without any problems, but now I am having issues.
When I ID points which makes up the surface it gives me the correct Z level e.g. 24.5m, however when I hover over the surface it shows me the surface name and a different z level e.g. 0.65m. What is the reason for this difference in z levels? I think this may be causing the issue I am having when I add new points.
I select the surface and use the 'edit surface command' in the ribbon, choosing add point.
When I add a point at the level I require(23.89m), it puts it in a lot higher than the surrounding area, so I tried to put the point in to the lower z levels (0.4m) it puts it in a lot lower!
I used a 2d polyline to create a surface boundary for a surface created. The polyline is a closed loop. For the boundary type it is outer, unchecked Non-destructive breakline, and mid-ordinate distance = 1.
My problem is that when I do this I only get a small portion of the surface to show up within my surface boundary. If I don't have a surface boundary the entire drawing surface shows up no problem.
The purple polyline is my boundary and the light blue is the surface created within the boundary.
I have a proposed surface that has been made by selection polyline with a z elevation as contours. Is it possible to have civil 3d easily change the weeding and supplementing factors to a tighter value after it has already been made?
I'm trying to create an all new existing surface over existing ground. I have a TIN surface of the EG, and I have drawn overlay splines that describe the new surface, but how to go about creating that design surface.
It is a compound surface, open on one end and closed all around on the other, somewhat like a half of a football stadium, but with an irregular upper edge because I am needing to figure out cuts and fills to manipulate the EG into this new surface without costly major terraforming. There is about 40-50' vertical elevation between the "field" and the upper rim with a generally constant 7-10 deg. slope all around. I'm just at a loss to figure out how to approach this project, and am quite new to Civil 3D.

Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.
The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.
I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.
1. Novapoint is quite unstable and crashes alot
2. You cant create profiles out of 3d faces
3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface
4. A large surface made out of 3d-faces demands alot of computer power
So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.
I have survey data of the inside floor of a pond ( the pond has a flat floor ). The surface made from the survey data needs to extend to the outline of the pond instead of the outline of the survey points.
I tried the smooth surface method of kriging with a grid base and I sellected the outline of the pond for the output region and that worked somewhat but there are still gaps between the boarder and the surface.
I have alignments that go in and out of a surface boundary (this is because I have a surface that represents the bottom of pavement.) I want to show the surface profile with the gaps in the profile view (where there is no surface. However in the profile view the gaps are sometimes connected with a straight line instead of being blank.
How can I have a surface profile represent the bottom of pavement properly? (An alignment that is not fully withing the surface boundary.) I know I could add the profile multiple time with different start/end stations But, I don't want that, I want it to be dynamic, as the alignment will change.
The odd shapes are outside the daylight line. They follow a straight-line around the daylight limits (see third attached file), apparently triangulating unwanted areas. I've used a corridor shrink wrap for the surface boundary.
What is the best bet? I'd rather not draw a polygon along the daylight line and use it as a surface boundary, since it could change. Setting a max triangle length in the surface does not seem to provide a desired result.
I have problems applying an Outer boundary to eliminate a small area within a big surface (and a few Hide boundaries within that Outer boundary): Civil 3D somehow creates extra triangles within my surface (that don't really make sense to me). I am applying the boundaries as non-destructive boundaries as I need the surface to extend all the way to my applied boundaries. The surface needs to be untouched (except applying a few Outer and Hide boundaries) as it is design data.
When I create a corridor surface I usually create a suface boundary automatically by daylight.Half the time this works fine, half the time it doesn't work at all. If I view the corridor in 3d view it looks fine.
I tried to create a shrinkwrap polyline to use as a boundary but when I picked the corridor in the shrinkwrap command
it locked up my computer. These are just simple corridors with no intersections. Why the automatic boundary only works intermitently? Is there a better/easier way to create the surface boundary?
I need to adjust a surface boundary. I need to remove a corrupted area in my surface. I do not need it. Is there any way to drag a boundary so I can exclude some of my contour area? Is there a command under settings on tool space that I may have overlooked? This surface was furnished by a client so I do not want to rebuild or alter except to exclude some contours.
what is the trick for holding triangulation within a surface boundary? I recall a setting somewhere but can't seem to find it... attached graphic, would like to hold the surface triangulation within the arcs which are in the surface definition as boundary
I use Civil 3D 2011. I have created a surface from a point group. Now i want to extend the surface to an outer boundary. To do so, i do the following steps:
- Select the surface and Extract the border object. - Create feature line from the extracted border polyline - offset this feature line (featureoffset) to outside specifying a offset distance and specifying the elevation difference as 0. - Add this offseted new featureline as the boundary in the definition of the surface - Rebuild the surface
Now when i am selecting the surface, I see that the featureline is not a part of the surface and I do not find the contours and the TIN extending to this new boundary. Also I still find the old border in the surface.
I'm creating a corridor to widen a road on the left and right sides. I am using OverlayWidenMatchSlope, with various other subassemblies. In places it daylights, in places there's a cut wall modeled from generic links. I am trying to create a good boundary for the corridor surfaces but I'm puzzled by one thing. The OWMS subassembly has a P2 code, but the corridor will not generate a featureline connecting the P2 codes..
I will try adding another baseline, and a new subassembly that will just use a generic link to target the sawcut line (the insert point for OWMS). That should give me a featureline I can use for a surface boundary. Is there a way to generate that featureline from the inside edge (the insert point) of the OWMS subassembly?
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 problem with corridor surface boundary , in curve boundary line is jumping on daylight fill , but i have created surface on wearing layer ,also when i am adding boundary there is only 3 types of adding , corridor extends , polygon and interactively , photo attached.
Civil 3d 2014.... I have existing surface and a profile with 5 sample lines. All of them are good except 1 sample offset. I can do I quick profile and the profile looks like it should but if I generate an actual profile 90% of the profile is off. I have already tried reoding the alignment but it looks same on either one.
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.
I have a survey of an existing road surface and need to show where water will collect (pond). I can obviously use the water drop function and show where water will flow over the surface, but what I need to show are the resultant pond extents on the surface.
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 don't undrstand why my assembly line increased after the existing surface in cut and fill condition, it should be stop at the existing surface. due to this problem my cut and fill quantities is not coming accurate. I'm attaching the screens shot of section. I'm using civil 3d 2009 32 bit software.
I have a rather large project for a roadway reconstruction. Therefore, the existing utilities are in a separate drawing and the existing ground surface model is in a separate drawing. All the above surface items (curb and gutter, asphalt, concrete, signs, sidewalks, landscaping, etc..) are in the master drawing. I then xref'd in my utility drawing and though I would use data shortcuts for my existing ground surface drawing. I took the surveyed triangles (3d faces) from our raw survey drawing and copied them into my surface drawing, created a surface from the triangles, created a boundary and such. So far everything is good. I created the working folder for the data shortcuts for this project and saved the drawing and closed it. I went into my master drawing and clicked on "Create Reference". I did not promote. The reference came though and everything is fine. Now I want to add contour labels in my surface drawing which I did but they do not show up in my master drawing but the contours themselves do. Do I have to promote this drawing into my master drawing so I can create the contour labels in my master drawing? I guess that is fine but the issue is we have small areas of topo that will be added as needed down the road. If I promote the surface drawing into my master drawing then when I add topo to the surface drawing, it wont update in my master drawing.
I have an existing surface with a steep slope and a feature line for the edge of a proposed walkway. I need a buffer of 25m on either side of the walkway but offsetting doesn't take the grade of the slope into account. How do I grade down the hill from the feature line at 25m to match to the existing surface?
