AutoCAD Civil 3D :: Compute Materials Top Surface Will Not Show Up?
Jul 11, 2012
testing out using link to marked point and volumes i made a 1000' alignment, flat surface at 0, and put a generic lws 10' wide at 0% slope so i would know the real vol in my head to check. i omitted the lws link and then put a marked point at the center of the subassy and then put a linktomarked point and it put the link in ok as shown in the picture. the corridor made a top surface and if i make a vol surface all is correct.
but when i hit the comput materials > earthworks only the eg shows up.
the linktomarked point has top,datum codes by default.
In Compute materials, Eartworks field dialog I have two items in Surfaces section- EG and Datum. When i have to select Object Name for them i only get surface name, but not the corridor which i have created. What is missing?
I am having issues having two separate areas combined into one with subcriteria. While I can get them to figure independently of each other (see image 1) I need to have them combined into a single fill category. While I think I am using the subcriteria interface correctly I can’t find an example of a way to set it up to work correctly (see image 2).

I'd like to build a location-based quantity takeoff using compute materials (actually using a mix of QTO, composite volumes, and maybe parcels and bounded volumes but this question is specific to compute materials). I have been working on this technical challenge today and hope to have it solved by tomorrow morning.
I created a new 'Quantity Takeoff Criteria' and added materials for the items I'd like to takeoff with compute materials, such as the corridor shape volumes that are not well handled by QTO. So there are structure quantity types for materials Pave1, Base1, Curb, RW.Footing, Wall, and Barrier. But, when I return to Compute Materials I have the option to assign 1 object to each corridor shape named. Here is the problem, there are 36 pave objects named Pave1 and only 1 material Pave1.
The solution I tried is to go back and edit the code set styles to add a location prefix like 99CL1>M>06 to the link names - making 36 99CL1>*>**-Pave1 objects. But, apparently these are links and obviously not objects so the names did not go through to the compute materials objects list.
The next two approaches are: 1) Go back to the subassembly properties and edit the codeSetStyle with prefixes - I assume this means I'd need a distinct subassembly for each location, a unwieldy situation. 2) Create a specific material and shape pair for each location, for example 36 99CL1>*>**-Pave1 material and Pave1 shape pairs. An awkward workaround but preferable to defining a specific subassebly to each location.
I need to run two reports one for Cut and Fill, and one for Materials (shapes). I would like two material lists for the same alignment and sample line group.
The process, setup the materials list for Pave, Base, and Subbase. Generate report, delete list and setup for Cut and Fills, run the report. You do this over and over. Autodesk please add a way to save and import these setups, and a way to create multiple lists for each alignment and sample line group.
Note: Why the Civil 3d default for the interlude into the actual Compute Materials dialogue is Pave, Subbase, Base is beyond me, could someone tell the programmers that Subbase is generally below Base. Each time I have to delete the CIvil 3D defaults and redo this step.
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?
I created a new surface, pasted my OG surface into it, set the build to exclude elevations less than and greater than but my surface still is showing every contour range. I want to only show contours at elevations of 371.5 and 370.5
I created a surface with the style showing slopes as 2D solids. I extracted the slopes from the surface and moved them to their own file. They look fine in the file where they reside. When I xreference them into a drawing, they no longer show up as solids. They just show the outlines of the triangles.
I know I could change the style to to 2d hatches instead of solids, but I'm more curious as to why this is happening and how to fix the 2d solids.
I am working on a large park project. I have a proposed and existing surface. I have created a volume surface to show elevation banding with cut and fill ranges. I need to create a drawing for someone who doesn't have civil 3d showing all the "cut" areas. They really want a boundary of hatch. What is the best way to do this after I change my analysis to -30 feet cut to 0 feet cut.
I'm having trouble trying to place a material onto a surface so that it aligns with the x-y coordinates. When I use drag and drop from the materials library and use ctrl to select one particular surface/face, the material drop s in fairly arbitrary.
I thought I could use materialmap to force it into a particular alignment and while I can use the commands to set the base point and alignment, the material does not update with the boxed alignment.
I have a problem with Bill Of Materials in drawings.
I want to show a structured list of the top level components in this general arrangement. But whenever i select a view for inventor to create the table it only gives me to option for 'Components Only.'
I have edited the assembly and switched off the 'Components only' option in the IAM, but it still will only let me put a parts only BOM into the drawing. I have right clicked the node in the IDW browser and selected 'bill of materials' and here i have also switched off 'parts only' but still the same.
How to make the name of a material show up in the Compact Material Editor? For instance, if I double-click on a standard material, and put it into the first material slot, the name stays "Default-01" instead of "Concrete_brown_stucco" (for instance).
This isn't a BIG deal but it's just one more thing to slow the workflow down !
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.
I 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?
I 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.
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.
all of a sudden whenever I run audit on my corridor file the surface definition becomes a snapshot. To add to the drama, the corridor surface will not paste into an empty surface. Why?
My problem added with pic ... I want to make volume calculate for sample road project. When I try to compute materials I cant use Corridor surface for DATUM... There is only target surface on option..
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.
I 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?
I have several hypothetical well bore lines. They are deviated wells which means the lines go straight down from the surface for a bit and then continue down at an angle. I need to buffer these lines in 3D space.
I've used the buffering topologies tool, but all it get is a buffer around the what would be the "plan" view of the well bore. Is there anyway to get the program to buffer around the actual 3D line and compute a volume?
