I have an existing surface with a steep slope and a feature line for the edge of a proposed walkway. I need a buffer of 25m on either side of the walkway but offsetting doesn't take the grade of the slope into account. How do I grade down the hill from the feature line at 25m to match to the existing surface?
View 3 Replies"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.
why I would get gaps in my grading from a single feature line? The feature line is at the same elevation all the way around and I am trying to grade to my existing surface at a 1:1 slope. No matter what I do it continues to leave out portions of the grading. I have attached a 3d image showing what's going on.
View 1 Replies View RelatedI have grading style set up to create a cut/fill boundary and the same thing for my corridor. I made surfaces from my grading and corridor and no longer need them. I need to keep the cut/fill lines for my design. How can I extract these lines from these objects? I tried keeping the grading/corridor on one layer and lines I wish to use on another so I can turn pieces of the grading off. However, it will not print the cut/fill boundary without printing all the feature lines created from a grading.

I have a polyline (elevation added in via Properties) that I want to convert to a feature line for use in grading but when I try to convert I get the message below
When I check the properties and do a LIST the list reports a negative elevation.
When we apply surface projection gradings to feature lines, we get locked vertices on the feature line wherever the grading transitions from cut to fill. In turn these vertices create segments in the feature line which influence any labels applied to the line. I don't want a bazillion segment labels on my FL. I only want segment labels between the physical vertices and elevation points. Is there a workaround or is an enhancement request in order?

I understand I could possible to a create grading feature line for a stoop, but what happens if the stoop would be irregular shapped and not a rectangle?
View 5 Replies View RelatedI needed to remove a feature line that I used as a break line when creating a surface. When I removed the feature line from the definition of the surface, the grading did not change. It appears the points created by the feature line remain which is why grading didn't change. The only work around was to delete these points.
I noticed the same thing happens when I removed the surface boundary and inserted a new boundary. why these points remain and how to remove when I delete boundary and feature line from surface?
I created a label for retaining wall that takes the z value from the start and end of a feature line. Works great except that it isn't dynamic. I have created the feature line in a grading sheet where the surface is data shortcut into it and I'm just using grips to make sure the ends are on the bottom and top of the retaining wall. Is there any way to dynamically pin/tie the feature line to a surface that has been data shortcut?
View 9 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.
This is the message I get when trying to elevate a featureline to a surface in C3D 2012, SP3. The featurlines (4 of them) lie entirely within subject surface but I am unable to get this command (AeccFeatureElevsFromSurf) to complete correctly with any of them.
The 4 featurelines are at the red arrows, a corridor from the centerline at the green arrow has been created, from which the subject surface was derived and is depicted by the yellow & green contour lines.
I don't undrstand why my assembly line increased after the existing surface in cut and fill condition, it should be stop at the existing surface. due to this problem my cut and fill quantities is not coming accurate. I'm attaching the screens shot of section. I'm using civil 3d 2009 32 bit software.

Is there a way to add elevation labels at any position on a feature line without having to create a surface?
View 9 Replies View RelatedI have a created a surface from contour lines.I have drawn a feature line and assigned elevations (it slopes down from 3.5m elevation to 2m elevation). I have added grading from the feature line to the existing surface but have not merged the feature line with the surface.
I also have to make a low area (elevation at 1.5m) on the surface and know i need to grade at 1:1 from the feature line to the low point. Is there a way to grade from a feature line at a given grade (1:1) to a known height (my low point at 1.5m) without drawing another feature line for my low point? Seeing as the height of the feature line varies I can't just offset it at the grade.. I.e. the grade is the constant here.
I will have a few walls and lower / higher areas to grade to. I have drawn the top of my wall and mounds and have assigned them elevations but not sure whether to now make them all feature lines and try to merge with the surface by grading at a set grade or to do some sort of infill.
I have this problem when creating grading groups with more than one feature line in them. It seems really unstable when you trying get the grading to connect. I have tried to create two separate grading groups in one site or two feature lines in one grading group. And the result is the same, the grading that will be create can sometimes look oki, but suddenly they tend to disappear or look weird...
View 4 Replies View RelatedI'm trying to create an all new existing surface over existing ground. I have a TIN surface of the EG, and I have drawn overlay splines that describe the new surface, but how to go about creating that design surface.
It is a compound surface, open on one end and closed all around on the other, somewhat like a half of a football stadium, but with an irregular upper edge because I am needing to figure out cuts and fills to manipulate the EG into this new surface without costly major terraforming. There is about 40-50' vertical elevation between the "field" and the upper rim with a generally constant 7-10 deg. slope all around. I'm just at a loss to figure out how to approach this project, and am quite new to Civil 3D.

I have feature line with elevations that represents bottom of ditch and want to go UP 3:1 slope. also i have edge of road feature line that is higher than ditch and want to go 2% down until it hits side of the ditch that is 3:1. Any easiest way in civil 3d to create intersection line between ditch bottom going up 3:1 and edge of road going down 2%?
View 2 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 show the surface in the prospector but there is nothing there. The one levee will show contour styles but this one ZIP!

View 4 Replies View RelatedWhen creating Feature Lines, I wanted them to be e.g. Step Line 1, Step Line 2, Step Line 3 etc so I amended the name template to suit. I created multiple from objects and the naming convention worked. If I did features individually (as I wanted certain ones in certain sites) it worked for the first feature but reverted back to the default Feature line name on subsequent entry to the dialog i.e. it had "forgotten" the template name just set.
Am I missing something to get this to work correctly or is this how it's supposed to work i.e. useless for individual feature line creation?? This also happens for gradings.

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.
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.

View 9 Replies View RelatedI 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!
My goal is coming up with the volume bounded by the design surface and the existing surface. I don't have the design surface modeled yet.
Do i need to create alignment offsets?. Alignment 1 profile view is also attached. Then Alignment2.
What about starting with alignment1 profile view? Since I have created a polyline as the design profile ?
how do I shrink labels? Where is it in the settings ; the Align folder had been check.
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.
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.
