AutoCAD Civil 3D :: Tie Feature Line To Surface
Sep 4, 2013I created a label for retaining wall that takes the z value from the start and end of a feature line. Works great except that it isn't dynamic. I have created the feature line in a grading sheet where the surface is data shortcut into it and I'm just using grips to make sure the ends are on the bottom and top of the retaining wall. Is there any way to dynamically pin/tie the feature line to a surface that has been data shortcut?

Jul 12, 2013I was wondering if there is a way that I can take an existing grade surface and apply a designed pond surface.
Right now I have the pond as a set of 3d Polylines in the proper geometry.
I want to place the pond into this surface and cut/fill at a 3:1 from that pond to the existing surface.
AutoCAD Civil 3D :: Elevate Feature Line To A Surface
Jun 6, 2013This is the message I get when trying to elevate a featureline to a surface in C3D 2012, SP3. The featurlines (4 of them) lie entirely within subject surface but I am unable to get this command (AeccFeatureElevsFromSurf) to complete correctly with any of them.
The 4 featurelines are at the red arrows, a corridor from the centerline at the green arrow has been created, from which the subject surface was derived and is depicted by the yellow & green contour lines.
AutoCAD Civil 3D :: Add Feature To Surface - Get Generic Numerical Name
Jan 16, 2013When I add features to a surface, they don't keep the feature name. It gets a generic numerical name ie dike:1, dike:2. Is there a way to get the names to hold? How does one keep track of the features/breaklines?

AutoCAD Civil 3D :: Grading To Existing Surface From Feature Line
Aug 2, 2012I 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?

Jul 11, 2012I am working on a 6 mile highway project whose surface file is 85MB big. So, I created a Data Shortcut of this surface and used this for creating profiles. However, at some locations the corridors go below the surface(as per their original profile) which was not intended. So, I need to restrict the surface to follow the corridors but not go beyond it.
I have created feature lines from corridors and tried to add them as breaklines to the surface. But " error adding breakline" error pops up.
Is it because I am trying to add the breaklines to the mirror surface which I created from Data Shortcut ??
Will it be useful if I copy feature lines to original surface file and add these feature lines as breaklines in that file??

Dec 11, 2012I needed to remove a feature line that I used as a break line when creating a surface. When I removed the feature line from the definition of the surface, the grading did not change. It appears the points created by the feature line remain which is why grading didn't change. The only work around was to delete these points.
I noticed the same thing happens when I removed the surface boundary and inserted a new boundary. why these points remain and how to remove when I delete boundary and feature line from surface?

AutoCAD Civil 3D :: How To Correct / Manipulate Surface To Show Proper Flat Surface
Dec 2, 2011I often have to do storm pond surfaces that (for the purposes of planning) are flat on the bottom. These surfaces are created from a combination of survey data and grading groups and the tin of these surfaces is perfectably acceptable. However, when contours are shown, the flat bottom is shown with contours jig-jagging all over the place.
The attached image shows a comparison of the same pond. The top was created with survey data and grading groups; the bottom was created using contour data only. The generated surface on the top shows the bottom contour going in different directions and has parts where the an expected contour is missing.
How to correct/manipulate the surface to show a proper flat surface?
AutoCAD Civil 3D :: Reduced Maximum Length For Surface Triangles Causes Surface Holes
Oct 22, 2012Has instances where you set your tolerance for the maximum triangle lenth to say 50m to reduce the amount of triangles along the edge that run at long distances. When I do this I end up with multiple surface holes and I'm not sure why as there are points in the area.
I thought well maybe it's because i should've reduced my max triangles first then added breaklines. Would this matter? I also thought I could add a line to the surface to fix the holes vs. deleting surface lines along the entire edge of a surface for many many miles.
AutoCAD Civil 3D :: Editing Existing Surface Using Edit Surface Command
Nov 14, 2012I 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!
AutoCAD Civil 3D :: Volume Bounded By Existing Surface And Design Surface
Dec 10, 2012My goal is coming up with the volume bounded by the design surface and the existing surface. I don't have the design surface modeled yet.
Do i need to create alignment offsets?. Alignment 1 profile view is also attached. Then Alignment2.
What about starting with alignment1 profile view? Since I have created a polyline as the design profile ?
how do I shrink labels? Where is it in the settings ; the Align folder had been check.
AutoCAD Civil 3D :: Add A Surface To Blank Drawing / Then Upload DEM Files To Surface
Oct 2, 2012I am issues with DEM files that I am downloading from the USGS website.I download 24k, elevation for the area I need. I then choose staged 1 second, add a surface to a blank drawing, then upload the DEM files to the surface.
The surface imports correcty, but when I try to import points taken by a surveyor on the same drawing, they plot incorrectly.The DEM surface and the points from the surveyor do not correspond. Also, the DEM surface is in meters, not feet. I have tried changing drawing settings, datum types, coordinate types, etc.

AutoCAD Civil 3D :: Import Surface Into Revit To Merge Surface And Buildings Together?
Jul 29, 2013I have a project involving 3 programs. I am creating a planned development in 3d to be 3d printed when finished. The project is a 5 acre tract containing 8 buildings. I have built the surface in C3D and each building in Revit. The buildings are not in the same Revit file. For my solid work, I will bring the files over into 3ds Max Design to section into smaller quadrants to build in the 3d printer.
The questions:
Would it be better to import the surface into Revit to merge surface and buildings together?
Would it be better to import the buildings into C3D to merge entities?
Would it be better to bring those entities into 3ds Max and then merge them into one? Will 3ds Max Design allow me to insert entities accurately in the environment?
AutoCAD Civil 3D :: Creating Subset Surface From Main Surface
Sep 15, 2013I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.
i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline. This seemed to work, but when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.
AutoCAD Civil 3D :: Create Cut Fill Surface From Existing Surface
Mar 1, 2013Im 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.
AutoCAD Civil 3D :: Corridor Surface Will Not Paste Into Empty Surface

AutoCAD Civil 3D :: Trim Surface To Another Surface
May 3, 2013I was wondering if there is an easy way to trim one surface to another. Right now, I have two slopes (3:1) that are perpendicular to each other. They meet at a corner and I have extended them past each other so that I could see the intersecting edge. Now I would like to trim them to each other like you would a polyline etc... but I am not sure how to do this.
If I select surf trim, it tells me they are the wrong object type, but they are tin surfaces?
AutoCAD Civil 3D :: Surface Boundary Only Showing Portion Of Surface Within The Boundary
Oct 24, 2012I 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.

AutoCAD Civil 3D :: Feature Line Projection

My profile is a separate dwg with plan view xref'd and surface a data shortcut. Of course there are feature lines and Survey Figures in the existing top I want to project into the profile, but can't because it is an xref. Besides copying .
AutoCAD Civil 3D :: Feature Lines Moving?
Oct 23, 2013So here's an odd one (at least I think it's odd ): I have a drawing that it utilizing feature lines which are projected to the cross sections to display R.O.W., easements, etc. However, every now and then (there doesn't appear to be any similar operation that causes this) the feature lines will change their location, in this case they typically seem to move north and east about 200'. I can't deuplicate the problem...it just seems to happen on its own.
I'm running Civil 3D 2013 with SP 2.
AutoCAD Civil 3D :: Edit Feature Lines
Jun 12, 2013I have created a feature line from a survey which will be the inside shld of my new road design. I have created the feature line using my design elevations but need to add a PI and Elevation at a specific Northing. When I try to edit I can only seem to find the chainage and elevation but I also need to know the northings and eastings so I know where to insert my PI. I would like to just edit the table since I can't seem to figure out how to insert the PI. (I am new to C3D and still learning...) My final product will be a road with 2% crossfall and I intend to use offeset and grading features to accomplish my final design. How I make this edit...
