AutoCAD Civil 3D :: Creating Depo For Excess Soil With Known Outer Boundary
Sep 17, 2013
I have a known outer boundary for my depo for excess soil. I know how much (volume wise) is going in to the depo. I know that the slope is 1:2.
I do not know where the upper boundary (top of the depo) of the depo is. That's what I would like to find out.
I know that I can create a upper boundary with a feature line and then use the grading and volume tool in order to find out at what height the upper boundary is placed. But then the outer boundary is either too small or exceeds the known boundary.
What is the easiest way of finding out where the upper boundary is? I am thinking about drawing a feature line around the known boundary on top of the EG surface and then using stepped offset. Then I can check out the volume.
But is it possible to do this automatically instead of manually?
We have a client who is looking to dispose of a large quantity of excess soil on a vacant property. We plan to hold the elevations near the northern property line, slope 2% in a southerly direction, then tie in at 3:1 slopes along the southern property line. What is the best method to determine where the break point between the 2% and the 3:1 tie grades would be?
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 try freezing my proposed storm structures inside Viewport for Existing Conditions sheet. My proposed DI's freeze because they use a block (in structure style). My proposed headwalls use the outer part boundary from catalog. BUT both DI and Headwall Style Component Layers are set to C-STRM-STRC.
In the pic for Existing Conditions Layout, you see a white headwall boundary. In proposed layout, you see a magenta headwall boundary. It's using the Object Layer and not the component layers for the headwall.
I didn't see another way to logically set up Object Layers for Pipes and Structures that contain Existing and Proposed Water, Storm, and Sanitary. My Object Layers have Pipes set to C-UTIL-PIPE and Structures set to C-UTIL-STRC, BUT the Component Layers inside the style are specific. Example: Existing Storm Structures and Pipes have layers such as V-STRM-PIPE and V-STRM-STRC. Proposed Storm would have Component Layers such as C-STRM-PIPE and C-STRM-STRC. The Object Layer for both existing and proposed use C-UTIL-PIPE and C-UTIL-STRC.
How I subivide and get the interior lot lines dito not show over the outter lot? I don't do a lot of parcel work just trying to make it easy for the others

When cleaning up a surface, I've always created an Outer Boundary to define the surface limits so that the triangles wouldn't go where I didn't want them.
I'm trying prepping in hopes of sitting for my Autodesk Civil 3d Certification exam at AU. The chapter I'm currently reading through talks about deleting triangles from the surface.
So now I'm wondering about the pros and cons of both methods.
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?
Let's say I have a letter 'B' and I want to create an outline on the outer boundary only and not the inner boundary i.e. the two small 'D', how can I achieve that?
I have downloaded the SSURGO file from Web Soil Survey. They are in .shp files, I have imported the spatial files into AutoCad Map 3d 2012. My goal is to create a Topology so that I can detemine the soil type and acres of parcels of land.
When I click on the polygon in my drawing it is a closed polygon with double line or overlapping lines and it does has object data but it is part of the line not a point as I am used to.
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
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 am looking at a large area with approximately a thousand parcels in a shp file. The polygons of course are independent and the lines sometimes don't touch or they overlap. I want to be able to draw a perimeter around the parcels. What is the best way to draw a boundary? I have tried exploding the polygons and then delete all the non essential lines and then try to create it that way but pline edit and join doesn't work and when you are looking at 10000 segments and the overlap issues or not even touching. I am just trying to save hours if possible.
I'm having problems creating a boundary patch on the attached model, Its a Y-Pipe joint in 3 planes that I'm attempting to split in half. I've used a silhouette curve to create a centre line in a 3d sketch then joined the ends together, however when I try to select the lines to create the boundary patch it only allows me to select some not all of the lines.
1. find the attached “Rays on Oval.png” file. (Tried attaching .cdr file but the File Size is 400KB.)
2. I would like to Repeat / Duplicate that Black Color on Outer Path of Oval Shape. (Like shown in the Yellow versus Black. The Yellow is a Circle and the Black is from Star Tool)
3. I think the Best Bet would be to Link the Rays to the Outer Path of Oval Shape.
4. I need the Rays and Oval as 2 Different Objects so that I could Change the Color Scheme.
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.
Is there a method to obtain the overall Site boundary? I have not found one, if there is, but it would sure come in handy when creating reports. We must always include the project Boundary as the first item in a report, so being able to add it to the existing reports would be a huge timesaver.
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 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.
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've attached a screenshot of the issue I'm dealing with. I have a closed polyline and when I first hatch the area it appears to be correct, but then I'll go do another command and then the hatch seems to extend beyond the boundaries of the polyline.
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.
I have just received a drawing, and getting message on excess drawing scales trying to xref it into drawing, how do i change scales, get rid of all different annotation scales how can i purge it?
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 like the 'Extract" feature for surfaces, where I get get the contours or boundary of a surface in PL form without having to explode the surface. I have not figured out how I can do that same thing for grading objects. So far I have been exploding grading objects and then remaking them. Seems cumbersome.
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?
