AutoCAD Civil 3D :: Surface Profile Boundary
Aug 14, 2013
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.

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 would like to show the title boundary of our site on a profile in a way that is dynamic. Same idea than on cross sections, where you can create an alignment running along the title boundary and then show a block where the boundary lies on each cross section. I know I could project a cogo point where the alignment intersects the boundary.
This method is not perfect because, if the alignment changes and, therefore, the intersection point with the boundary changes too, the cogo point won't follow the alignment, staying at its original location. Hence, I'll have to update it manually. I tried using a feature line, but it seems I cannot show a marker only where it intersects the alignment.

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.

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 need to convert my surface boundary to a polyline so I can use it to clip another surface. Is there a simpler way than tracing it with the polyline command?

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.

Cannot get corridor surface boundary from daylight points. Is there another way so that I do not have to trace the outer limits?

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?

Im creating a Profile Bandset and would like to have multiple surface/profile elevations shown, ie: EG, FG, Back of Curb and Back of walk. While creating this bandset I see that the text component editor properties only has code for profile 1 elevation and profile 2 elevation in the properties area, which the code for this looks like below.
<[Profile1 Elevation(Uft|P2|RN|Sn|OF|AP)]>
<[Profile2 Elevation(Uft|P3|RN|AP|Sn|OF)]>
Ive tried to write my own code using the profile 2 as an example but it doesnt seem to work as a 3rd surface/profile and only seems to mimic the profile 2 elevation when placed in the band
My questions are as follows
1) does Civil 3d only allow 2 surface elevations in any band set? if it does allow more profiles/surface elevations what am i missing to create it?
2) if Civil 3d does alow for multiple surfaces to be shown in the band set how do i get the text component editor to supply the extra profile elevation codes? or would i need to create from scratch
3) if i need to write the code from scratch does any listing of the codes and meanings of each code ie what does RN, Uft, Sn and so forth do and mean .

I have a profile showing proposed storm sewer, existing sanitary, rock surface, existing surface, and proposed profile. Today for some reason the proposed profile and labels, and the existing surface are not showing on the profile and I'm not sure what has changed or how to get them back.

We have an engineer who is taking an existing surface and wants to show a proposed road 2" higher than existing.
I told him to simply adjust his assembly for his corridor to account for the 2" difference, but the County agency needs to see a profile.
My questions:
1) Is there a way to easily copy a profile made from a surface and "convert" it to a proposed profile? If we copy and explode, it turns into hundreds (thousands?) of tiny pline segments and it would be a mess to convert all those to a profile 1 by 1. If we make the corridor, and choose "profile from corridor", we do not have an option that could be used to represent the centerline.
2) Other than loss of dynamic updating), would it make sense to adjust the assembly so the top surface would be accurate, then copy the profile, explode the copy to a block and simply shift that (as essentially basic linework)?

Attached are survey points that created the surface of a road embankment portion that caved-in. The road is very near a reservoir shoreline.
1. How can a surface profile be produce? I/'ve use line to change it into an alignement and then create a proile , then a profile view. But the the surface profile is missing.
2.the points having higher elevation are the top edge( road level) of the cave-n . A few few shots were take before the shorline elevations.
3. What the best way to come up with the rock volume to fill the cave-in given this surveying points., Also the shoreline elevation will be lowered some more while work is being done since the fill is not allowed to fall in the reservoir.

I have created a surface from a corridor. I set the boundary of the surface to the daylight of the corridor. In some areas of the corridor the surface does not triangulate see attached.

i need to know if there is any way to control the points in the point cloud.
1. either only import the point cloud in a polyline area i specify
2. add all the points within a boundary not limited to the pointclouddensity = 100, freaking default is 15 almost cost my job today. extremely stressed out right now.
i am talking about extreme lidar surveys. 1km 1km LAS/0.5m contours/xyz files times 355 of them. covers a 2km wide corridor. but i only need 100m wide after i define the road alignment. no need to have all the extra points.
right now i densify the heck out of it and end up like 5-12m points. decent but not good enough because the geotech is bitching about that accuracy is not good for some feasibility study. or is there any software i can do this besides civil 3d.
what i want can also do is automate the 'add points to surface" under point cloud and have the software do multiple boundaries without having me baby it over the night. right now every click is 5 minutes and adds like 400k to 1 million points. Civil 3D 2012

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 a surface profile which has 2 surfaces in it. The surfaces overlap, and where there is overlap I just want to show one surface. Right now it looks like I'm going to have to smack a new boundary on the one surface to clip it, but I thought there might be a way to limit the display range of one surface in the profile.
Right now, I've only figured out how to do this so both surfaces are limited to the same range, but I can't figure out how to do it if you want to just control the range displayed of one surface and show all of the other surface.

I Created a profile from existing surface and created a layer called "PRO-EXISTING" and set linetype to "HIDDEN". I also set my standard style to display linetype "BYLAYER" but my dashes are not even like polylines when plinegen is "ON"

i need to transition from a proposed to a future linetype part of the way down my profile. It's the same surface, just that @ station XX+XX.XX it becomes future. I need it a diff linetype to faded back, for example. Is there a way to do that? I'm thinking my only option is two create two surfaces, one propsed and one future. My situiation currently is that I already have one complete surface and would like to know if it's possible.

I have a drawing with surface profiles and the linetype generation is working on some and not the others. They're all dynamic and they're not dref'd in and like I said, a few with the same style look correct and a few are incorrect.

I have modeled a storage pond on my site and I have the existing surface hidden for the extent of the pond.
Is there a way to make that hidden existing surface, show up on the profile view?
I have attached images to better explain myself.
