AutoCAD Civil 3D :: Adding Retaining Walls And Curbs To Surface?
Nov 9, 2013
I am having a lot of trouble adding retaining walls to my surface. I also have to add the curbs of parking lot.
I already have the surface. However I need to tell Civil3D to stop the contours at the retaing walls and not to try to tie them in to anything else. The closest I got was using wall breaklines and I got the top of the retaining wall to have the desired elevation. However, all the contours going to the retainig wall try to go around it and tie in to something else. This ends up creating weird contours and crazy slopes.
Now for curbs, how do I tell Civil3D to jump 6" when it reaches the curb line?
I cannot figure out how to create a solid surface on top of the retaining walls and also how to grade the transitions for the high to low points of the retaining wall. This would be so much easier for me in Solid Works
I am in Civil3D 2012, and am trying to render a retaining wall we doing. I set up a corridor, surface, and profile, and have it working with plans and such, but when I try my hand at rendering it looks rather odd. The surface is fine, and I can choose materials on the vertical wall subassembly, but It just shows a paper thin object ever 25' and a large surface on top. Does the top of the wall need a feature line as well.
we are in a situation where we want a dynamic wall label. how can i make that happen if technically the top of wall and bottom of wall are at two different x and y points. ideally i would like have one label and list it this way by referencing surface elevations:
I am trying to visualize a road project. The problems is, whenever the corridor surface goes below the EG surface (when the road is in cut) the EG surface is the only visible surface.
I sort of need to subtract the corridor surface from the EG surface, or merge the both surfaces into one.
A lot of my work is on steep slopes, and I need to incorporate sloping driveways, parking areas, site retaining walls (boulder walls as well as inter-locking block walls), benches between the top of one wall and the bottom of the next, re-grading, and landscape plans into the design model.
It seems Revit lacks any real site tools to accomplish these tasks, and there are some work-arounds. I've been playing w/ floors for a sloping driveway, but it's tedious and the results are mediocre at best. Haven't yet played with ramps for driveways. I haven't yet figured out a good way to deal with site retaining walls, where the bottom is sloped to match the driveway, and the top is at a different slope to match the existing/re-graded terrain above.
Any work-arounds to address issues with modeling driveways & retaining walls on a steep site?
I'm trying to create an assembly that consists of two curbs sub-assemblies that are tied to independent alignments with a pavement section in between them. I have been successful in actually creating an assembly with the two curb sections, but I cannot figure out how to define a line or pavement section that will connect one gutter to the other.
I have one curb tied to the main baseline and the other tied to an offset. I have assigned horizontal alignments and profiles to the baseline and the offset. The curbs actually place where I want them when viewed with the section editor. I had thought that I could use the LinkToMarkedPoint subassembly and simply attach it to the gutter of one curb and to a marked point on the gutter of the other curb, but I can't get it to actually work.
Again, the curb alignment and profiles are completely in independent one another, and I need a way to define a pavement section (or just a surface) between the two gutters.
I have got a csv file and want to add to the surface but it says error in adding point file.....don't know what to do. Size of the csv is 13MB and contains about 0.2million points.
I have created a surface with a point group. I have a few points on the edge of my surface that need to be added to the surface. I can add them to the point group, but when I updated my surface nothing happens. The triangles don't extend to my newly added points and my profile of the area doesn't show a surface where these new points should be. the new points I want to add have the same properties as the other points in the point group, they are cogo points.
I am using AC3D 2014. I have created a surface from downloaded DEM points, but, as expected, the contours are not as accurate as I would like. They vary from known elevations anywhere from a few inches to several feet.
I also have survey data from approximately 500 points which include Northings, Eastings and Elevations. Is there a way to add these points to my existing contour surface and incorporate these know NEZ points such that he contour surface is more accurate?
I have already converted my "known point" file to a .txt format with comma delimited information.
When working with multiple building pads and configurations change rapidly. Is there a method to add a Block or Xref into a Civil3D Surface under Drawing Objects? If so, how could you do it.
I want to have a building block type 1 that I can update the block or xref then updates the surface rather than doing each one individually. The Block would have a FFE of 0.00 and then the stoops, etc would either be a 0.1 drop or so.
I am placing a lot of suface slope labels in my drawing (as in hundreds). The default settings force you to choose a surface, and then to place it by selecting 1-point /or/ 2 points. The CAD default is the 1-point. Is there a way to change this default to the 2-point so I dont have to change it everytime?
When adding data to a surface, there is the option to add it as a "Non-destructive" breakline. [URL] .....
What is this good for? I created a surface, copied it, and created a volume surface between the two of them. As expected, the resultant volume was 0.
I then draw a 3d polyline and snapped to elevations on the surface. I then took that 3d polyline and moved it up 5'. I then added that breakline to the surface as a "Non-destructive" breakline and the resultant volume between the original surface and the one modified with the new breakline was still 0. Absolutely no change was made to the actual surface, it just added additional triangles.
I'm trying to find a reason it's even option and I'm coming up blank. There has to be SOME reason it's there.
When adding break lines to a surface, a dialog box like appears that asks for weeding factors and supplementing factors. What I would like to know is, how can I change the defaults to reflect the settings needed on my project.
I 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??

I have a platform at level 13.275m and nearby there is a retaining wall at aprox. level 4.0m.
For the wall i've made a surface using feature lines from EG till level 15.0m and then pasted into the EG surface to create the 'barrier' for the slope. But when i do the grading with the fill slope projection to surface, when it reaches the retaining wall section, the contour lines go crazy and if i do a quick profile, the fill slope line (obvious) is iregular, rather than a straight down line (2:1) going from level 13.275m till it hits the EG.
I've attached a picture to show the problem better.
I'm new to Revit. For instance I was working on adding foundation slabs to my walls .. all walls were done and had slabs beneath them and one wall still didn't have any. Once I tried to add the slab to that particular wall ( just by clicking on it, like ive done with every other wall ) it fails to do so and doesn't add any slab.
But my main problem is, sometimes when I work on my project everything becomes UNCLICKABLE, I do not know what im doing wrong and the only way for me to add walls or anything is by clicking CTRL+Z untill the meny gets highlighted again.
I have a series of curved feature lines in Civil 3D where the elevation varies along the length of the curve. When I export the file in AutoCAD the feature line elevations are 0. In my previous version of 2010 civil 3D this did not happen but now I am running 2012 version and I can't find a way around it.
Why does 2012 Civil 3D not export feature lines the way it did in previous versions and retain the elevations?
I have numerous text objects I want to rotate 180 while retaining each text objects insertion point. There's got to be an easy way to do this.
Long explanation: I created an annotation template to label pipe diameters on an imported shapefile. Everythings good, labels are parallel with lines, except for the fact that some labels are upside down. Is there an expression that would eliminate this? In my annotation template, my rotation expression equals the "angle" field of the object. My "quick and dirty" fix was to burst the annoation labels, and manually rotate necessary text, which wasn't a huge headache since I'm dealing with a relatively small number of labels, but in the future I might have hundreds of upside down labels.
I have an assignment to draw a bathroom. I have walls that are spaced 3 5/8 inches apart and the drawing shows insulation batting between them. When I use the batting insulation linetype and run a line between the walls the batting symbol extends beyond the 3 5/8 inch walls. how do I get it to fit between?
how can i draw this plan without knowing the angles for each wall? when i draw , the last wall is incorrect can autocad adjust the angles of walls for me after typing the length of the walls ?
I created a new wall type that includes Stud, Sheathing, and Rigid Insulation. I need to show the existing CMU walls cutting through the new Stud walls. Can this be done?
I 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?
Has 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.
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 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.
