AutoCAD Civil 3D :: Grading Groups And Multiple Feature Lines

Mar 19, 2013

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...

AutoCAD Civil 3D :: Grading From Feature Lines

Aug 15, 2013

I 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.

AutoCAD Civil 3D :: Creating Objects (Feature Lines / Grading) With Naming Template Query

Jun 26, 2012

When 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.

AutoCAD Civil 3D :: Infill Grading VS Feature Line Grading

Dec 24, 2013

"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.

AutoCAD Civil 3D :: Grading Groups And Surfaces?

Jul 8, 2013

I have created several pond embankments using the grading tools and have created surfaces using the grading groups. The problem I am having is when I turn on the triangles for one surface, I get the triangles for all the embankments and EG. The software keeps adding to the EG and doesn't cut out each embankment. I know I'm missing a step but I'm unable to find it.

AutoCAD Civil 3D :: Merging Grading Groups

Oct 3, 2013

I'm currently trying to model all siteworks for a project using Civil 3D 2014. I created several grading groups that represent the various pads I need for the general project layout.  Since this was the way I knew how to model the pads, now I have some intersections on the slopes between one grading group and the other. I was wondering if I could "merge" the grading groups in order for them to be just one big pad, that maintains all the levels from the other pads. Here is an image of what I am trying to explain:

What I want to do is to merge the regions circled in red, so that I have only one building pad on my terrain.

AutoCAD Civil 3D :: Move Multiple Feature Lines Between Sites?

Move multiple feature lines between sites?

Is there a way to move all the feature lines in a surface from one site to another site all at once?  I know how to do them one at a time, but when I select them all, right-click "move to site...", it does nothing.

AutoCAD Civil 3D :: Grading To Existing Surface From Feature Line

Aug 2, 2012

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?

AutoCAD Civil 3D :: Gaps In Grading From A Single Feature Line

Oct 10, 2012

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.

AutoCAD Civil 3D :: Extracting Feature Line From Grading Or Corridor?

Feb 22, 2013

I 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.

AutoCAD Civil 3D :: Convert Polyline To Feature Line For Use In Grading

Aug 22, 2012

I'm working on crane pads for a windfarm development and have run into an issue that has never happened in the other 60 or so ones I've done previously.

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.

AutoCAD Civil 3D :: Projection Grading Create Segments On Parent Feature Line

Dec 12, 2013

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?

AutoCAD Civil 3D :: Grading Objects From Curb Lines - Linking?

Oct 12, 2011

I have been creating grading objects from my curb lines, assigning grades using the editor, then offsetting that line for the BACK of curb, and using the raise-lower command to raise the curb line height. If I edit the original face of curb line (gutter grade) then I go back and redo the process. Is there any way to intelligently link these two lines so that if one gets edited C3D knows the other is 0.5 feet higher (or lower) than its neighbor?

AutoCAD Civil 3D :: Exporting Multiple Point Groups?

Oct 22, 2013

I have about 50 point groups that the client needs in an ENZ format, is it possible to export them all at once with the name of the point group being the name of the file?

if so, the more annoying part of this is that I actually have to make the ENZ file an ENZD file with the D being the name of the file for each point, if both of these things are possible

AutoCAD Civil 3D :: Multiple Auto Generated Point Groups

Mar 21, 2012

I am running into a problem where Civil 3D is creating multiple point groups of my 4 existing groups (the original group names are Topo, Existing Ground, Hide, and All Points).  The new groups seem to be copies of the originals in terms of styles but do not include the points  that were designated in the originals (no points are assigned in these copies).

The groups appear some time after I create the surface.

I've also noticed that this occurs in my list of grading criteria as well.

AutoCAD Civil 3D :: Viewframe Groups And Creating Multiple Double Plan View Sheets?

Jan 10, 2013

I new to using the view frame groups we do allot of double plan view 11x17 sheets using an alignment on top of MrSid aerial drawings. It is very time consuming to setup the viewports along the alignment doing the old fashion method of copying the page setup and sliding the model space along the alignment for the next sheet.  I understand the plan profile and cross section methods of creating multiple sheets and how the viewframe group works for those type of sheets.  I'm just not sure how to create a dwt template for one plan view on top of another plan on the same sheet with to viewports.  I know I'm not the only person that creates road cl double planviews when your not concerned about a profile.

AutoCAD Civil 3D :: Feature Lines Moving?

Oct 23, 2013

So here's an odd one (at least I think it's odd ): I have a drawing that it utilizing feature lines which are projected to the cross sections to display R.O.W., easements, etc.  However, every now and then (there doesn't appear to be any similar operation that causes this) the feature lines will change their location, in this case they typically seem to move north and east about 200'.  I can't deuplicate the just seems to happen on its own.

I'm running Civil 3D 2013 with SP 2.

AutoCAD Civil 3D :: Edit Feature Lines

Jun 12, 2013

I have created a feature line from a survey which will be the inside shld of my new road design.  I have created the feature line using my design elevations but need to add a PI and Elevation at a specific Northing.  When I try to edit I can only seem to find the chainage and elevation but I also need to know the northings and eastings so I know where to insert my PI.  I would like to just edit the table since I can't seem to figure out how to insert the PI. (I am new to C3D and still learning...) My final product will be a road with 2% crossfall and I intend to use offeset and grading features to accomplish my final design.  How I make this edit...

AutoCAD Civil 3D :: Exporting Feature Lines

May 13, 2013

I'm currently using the Autocad Civil 3D 2014 on daily basis for urban infrastructure design. When using Autocad Civil 3D 2013, I always would create feature lines from corridors and then export this file to a ACAD 2007 version, which would read the feature lines as 3D polys. The company's topographer could then use this file to make his markings on the field very easily.

Now, when I do the same process using  Autocad Civil 3D 2014, the ACAD 2007 file won't present the feature lines as 3D polys, but as 2D polys. This presents a major inconvenient, because I now have to export the file to ACAD 2007, open it in  Autocad Civil 3D 2013, rebuild the surface from the design contours and create a feature line from the design surface; export the surface AGAIN to ACAD 2007 and FINALLY I'll get the 3D poly my topographer can read.

AutoCAD Civil 3D :: Feature Lines And Sites

May 6, 2012

I am new to civil 3d. I am building a site down the side of a mountain which consists of 4 tiers/ pads with different levels. Each of the 4 pads has its own feature line. To prevent any confusion or attractions of the feature lines to each other i have moved them to a site that i created called temp site locations. 

What is the best way and location to do each of these gradings and how do i tie them all back on to the same drawing ? I assume (maybe wrongly) to do each separately and copy back into the the real drawing.

Do i need to create a new site for each pad. If i do my grading in the temporary site when i bring them back to the real site will the interact with the other feature lines.
