I am trying to create a proposed surface using grading. I created a closed polyline representing the site's outer boundary then created a feature line from 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".
View 1 RepliesI'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 Replies View RelatedI have two separate graded levees in my drawing. One has created a surface just fine, the other absolutely refuses to generate a surface. 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!

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.
We 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)?
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.
View 1 Replies View RelatedThe 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?
I have a existing surface. I want to create a proposal surface so I can know the volume between boths. This proposal surface is represent for a disposal area that can be filled up to a elevation. I have a bottom of P-surface as a feature line at EL 1608, and I want top of P-surface to EL 1613.

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.

I have a profile showing proposed storm sewer, existing sanitary, rock surface, existing surface, and proposed profile. Today for some reason the proposed profile and labels, and the existing surface are not showing on the profile and I'm not sure what has changed or how to get them back.
View 3 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 want to grade downward from that feature line at a shallow slope until it daylights somewhere down the embankment slope. How do I accomplish this? All I can get it to do is slope upward (cut) to the existing surface.

View 4 Replies View RelatedI 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 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?
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 9 Replies View RelatedAs you can see, the nature of my model forbids me from making a 3D solid using LOFT.
The top surface is consisted of 3D polyline and arc, which if "joined" will be become a spline.
The bottom surface can easily be joined into polyline.
If I loft the top and bottom, it'll only give me a LOFTED Surface, which is not I want (wanted a 3D solid).
I have a 5 acre surface which includes a 2 acre parking lot. I want to lower only the parking lot area to bottom of sub grade level and then grade back to surface at 10:1 for mass grading purposes.

View 3 Replies View RelatedI have an Existing Surface i created from survey data. I have a Proposed Surface i created with feature lines. Now i want to create grading around the outside portions of my Proposed Surface. I create the Grading Group and specified a projection surface and selected a Criteria Set for a 3:1 slope to match back to Existing Surface. I select the Feature Line i wish to create the grading from and progress through the cut and fill prompts and nothing happens. Nothing gets created. I have tried an audit on the drawing to see if errors are causing the problem and there are no errors.
I use this tool all the time and this problem comes up frequently. Especially if i have made any surface adjustments.

I am designing a fill volume. I have created my surfaces and feature line. My topos however are on two seperate layers as one is existing ground and the other is engineered ground. How can I get my grading to work using two layers in a grading group?
View 5 Replies View Related"An infill grading has no criteria applied to it. Any area bounded by feature lines or lot lines that is not already a grading can be converted to an infill grading."
So given an area enclosed by a feature line, an infill grading can be created. Using the same features line, an feature line grading can also be created. what is the difference between these two surfaces? They both have no criteria applied to them.
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.
how to use Civil 3D to create a grading plan for a solar PV site or a golf course?
Here is the situation. We have a large 100 acre site that is not flat. We want to do minimal grading to "smooth out the surface". So that maximum slope on the site is 10%. The site does not have to be graded completely flat. We are trying to work with the existing contours and terrain as much as possible.
Is there some functiion or some way for Civil 3D to "smooth out a surface"? We want to work with the existing slopes and contours of the site and just need a grading plan that will smooth out mounds, holes, or high slope areas.
I have a Grading Plan that is getting increasingly unstable as time goes on... I used Grading creation tools to create 3:1 mounding for a stock pile that is on my site... there are a couple dozen mounds on the site for this stock pile...
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?
