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 :: 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 :: 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 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 :: 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 :: Snapping 3D Feature-lines To 2D Objects?

Apr 26, 2012

If the 2D layout is updated I need to move featurelines and gradings to the new locations without changing their Z values. It seems OSNAPZ is supposed to serve this purpose but it's not working for me. I have OSNAPZ=1 and ELEV=0 but when I snap a featureline vertex to the 2D linework the vertex ends up at elevation zero. How do I make this work?

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 :: Joining Three Grading Objects

Apr 24, 2013

I have a compost pad and retention pond to design, I set my back Pad line to surface and then graded to elevation so the slope to the pond will have no cuts

I created a pond and left out the grading to surface on the up hill side towards the pad which will be paved one day. I now created two side feature lines to enclose the whole pad and graded by distance and slope.

My problem now is the two side and back seem to blend together as I attached the feature lines together but I can not figure out how to blend into the pond create as it has side slopes to EG and the front which must join to the side slope crest to enclose the pad to drain into the pond.

AutoCAD Civil 3D :: Surface From Grading Objects

Jun 20, 2013

It 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.

AutoCAD Civil 3D :: Grading Objects Disappearing When Editing?

Aug 18, 2009

Using 2010 with update 1 or whatever it's called these days, I'll just call it the first fix.

I've made three grading objects using "Grade to Relative Elevation" along a feature line. Then I've added a grading transition between them. This seems really unstable now, like making the wrong move makes the whole thing disappear...but what is strange is the feature line that is attached to the grading object that I have added into my surface remains, but there are only a few lines where the grading objects used to be, basically the line that seperates the different sections of grading.

There's no way to edit the grading again either, it has to be remade, because there is nothing to select.

AutoCAD Civil 3D :: Creating Grading To Surface With Slope?

Dec 30, 2013

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?

AutoCAD Civil 3D :: Grading Objects To Fill In Area At Building Corner

I have a Proposed Building Pad. Grading is 3:1 on 3 sides. Grading is 5:1 in the front of the building. How do I get Grading to fill in the area at the building corner between the 3:1 and the 5:1 grading? I thought infill would accomplish this but it seems to have no effect when I select the objects. I included a screen shot and the area at the left corner of the building.

AutoCAD Civil 3D :: Grading Tools - Creating Proposed Grade Surface?

Feb 21, 2013

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?

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 problem...it 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.
