I'm trying to create a proposed grade surface using the grading tools. I drew the outline boundaryof the proposed surface as a closed polyline then created a feature line from it and assigned different elevations to it. When I try to select the feature line in order to create the grading, I get "THIS FEATURE OVERLAPS ITSELF AND CANNOT BE GRADED". What could be a possible reason for this?
View 5 RepliesThe engineers at my company digitize proposed contours in a drawing and then they want me to create a surface out of the contours....the contours usually are 2 foot contours with areas that the software tends to translate based on the contours that I selected to create the surface.....I then usually need to create a profile, which does not look accurate compared to the contours, such as low spots etc...............
My question is since the engineers at my work do not how to use the software, and I am not an engineer, making the profile look a certain way sometimes needs to be tweeked by me.... How to alter the proposed surface?I am pretty sure that feature lines cannot cross contours that I have selected to create the surface?

View 4 Replies View RelatedI am trying to create grading slope from a Feature line that was created at a constant elevation of 609m. I want to create a slope of 3:1 from the feature line to a surface I created. I recall in AutoCAD Civil 3D 2011 that you could create a slope directly to a surface. Is there a way of doing that in 2014 or did I simply forget a step when I created my Grading Groups?
I created the grading group using the Grading Creation Tool Pallet and selecting Set Grading Group. Then I set my target surface to the one I want to grade towards. I thought all I had to do than was go to Create Grading select the direction of grading and the slope. I thought the slope would continue to the target surface but it asked for a distance for grade that would throw off any volumes I want to pull off.
Did I have to create a new surface for my Pad at 609m than grade from that and how would I make sure my slope continues till it contacting the surface I want to target?
I had a proposed surface in Civil3D2010 that was fine, made revisions to the proposed contours using grips or deleting/adding contours. Now when I try to add the new contour data to the surface either the program hangs up or I get contour error messages and the surface never gets re-built.

I'm working on a grading plan which excavates down from just outside the waterline of an existing pond. When I create a surface from the grading, it looks like a whole bunch of strange break lines have been added, messing up the surface. I thought it might be the mid ordinate distance but changing that doesn't seem to fix it it. Interestingly, when I grade from the original waterline, this doesn't seem to happen.
Here is my workflow, a picture of the result is shown below.
1. Turned the current waterline into a feature line.
2. Created new feature line by offsetting outside that feature line by 3.16 ft.
3. From new feature line, grade down 10 feet at 3:1
4. Create new surface using grading.
The grading lines (shown in white) look correct. But when I create the surface (green and yellow), it is all messed up.
When I paste the proposed surface with the corriodor surface and I check the profile the proposed surface ties to the bottom of the kerb ignoring the footpath.Also in the same drawing file I can't seem to export it to ACAD.

View 8 Replies View RelatedI 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.
When we created our fist C3D template in 2007 it was possible to make a grading criteria that targeted a surface at a fixed distance. In other words, the slope was variable. Looking at it again in 2013 it appears it's not possible to creat a criteria like that. Am I missing something? Or was that option removed? .....perhaps because it was too unstable?
View 9 Replies View RelatedI am at a crossroads with this corridor that I have to create in Civil 3D 2011, with a sub assembly that logically seems very simple...the conditions for daylight can be found in "Proposed Cross Section". In short I have 4 fill conditions and 2 cut conditions, based on height above original ground...(there are additional requirements for guardrails and retaining walls but at this point i will settle for my slope reaching original ground)
View 9 Replies View RelatedI built a containment dike using the grading functions in Autocad Civil 3D. I set up the feature lines at the top toes of the embankment and graded nicely down to the original dtm. I want to use user defined contour to get the interior storage from the original dtm up to a selected elevation within the containment dike. The containment dike forms an enclosed area. I know I could use infill and add a false bottom to the embankment surface (triangulation from bottom toe of embankment across to opposite embankment) but I want to check storage from original ground dtm.
Is there a workaround method to do this without creating infill? I know I need to get down to two surfaces to get a calculation.
I'm building up my assembly and I want to add a daylight sub-assembly in order to grade my proposed surface to the existing surface. Typically I would have a 1:3 slope up or down. I have choosen the DaylightGeneral for this and although there is quite a few parameters to play with, I'm only interested in the up/down slope but when I put anything sleeper than 1:4 it doesn't work, I get this red line and circle.
View 4 Replies View RelatedIt has been too long since I created Grading Objects and Proposed Surfaces. I am working in a file with my existing surface DATA Linked. I am creating a grading plan. I have created three separate grading objects in the Site named Proposed. One in the building, One is a new ditch, one is a graded existing ditch. I need to make these three with the unaffected areas of the existing surface into a new surface. How do I accomplish that . All my grading objects appear to be individually accurate and are created with a Feature Line and Grade to Surface Styles.

I've deleted the grading even the feature lines and re-did them. In my grading group I have automatic surface creation checked and the volume base surface checked. I show the surface in the prospector but there is nothing there. The one levee will show contour styles but this one ZIP!

My problem is when I go to edit any feature lines or Grading; the drawing just crashes and will not save my work... I ran an audit and it does not find anything... I need to get the grading done ASAP and this is a major hold up... Do I need to go back through and manual grade everything or is there a secret that I am missing?
I have read multiple forums on the matter with older version of Civil 3d... so this is to tell me that the problem has never been fixed with Autocad?
I attached 3 pictures describing my problem.
On the first one you can see the feature lines i'm about to grade. The closed line is a pond and the two lines on the right is a riverbed. The area between them is just land.
On the second picture you can see a part of the surface i need to get by grading. I need the pond, riverbed and land to be one surface.
On the third picture you can see what happens, when i try to grade the riverbed under the same grading group. The pond surface disappears while the grading stays.
I'm trying to replicate a dump surface from a cad file, but this one is rather different from what i'm used to (more simple and poligonal).
This one is curved and the top of the platform has inclinations has the picture shows.
I'm having trouble on finding the best way to aproach this dump surface. I tried to start from point 2 with the curved feature line and grade back 2% till EG and then grade forward 10% till it reaches point 3 at elevation (900) , but when i grade forward the sides obviosly dont hit my EG.
On my corridor I am using Link Slope to Surface, using a 3:1 slope. But it is giving me a 3:1 slope radial to the corridor - what I really need is a 3:1 slope between the contours themselves. On the inside of a tight curve, this makes a big difference. See the attached screenshot. Is there a workaround for this?

View 3 Replies View RelatedWe 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)?
