AutoCAD Civil 3D :: Surface Slopes In Small Area

Aug 2, 2013

I have a large ex surface that I have divided into basins and such. I know need to evaluate the slopes in these areas. To do the whole surface at once seems to not be possible. Is there a way in c3d to view analysis information for a section of surface for instance in a polyline or fence?

AutoCAD Civil 3D :: Takeoff Surface Area Of Daylight Slopes

Feb 28, 2012

What approaches are available in civil 3D to takeoff the surface area of daylight slopes?Which do you recommend for given scenarios?

I tried compute materials but the volume report for cut and fill area is zero - so either I missed something or the compute materials for surface area does not work yet. Then, I tried the QTO manager and linked the corridor codes slope_link and daylight_fill to payitems. Slope_link has a QTO of 1,458,099M2 and daylight_fill has 913.39M2; I have more confidence in the daylight_fill takeoff.

AutoCAD Civil 3D :: Surface Slopes On Grid

Nov 20, 2013

I was wondering if it's possible to add surface slopes on grid (similar to how there is a tool for adding spot elevations on grid). I can do them individually at a grid spacing but that's tedious, and considering you can add spot elevations on a grid, I'm not sure why this wouldn't be possible. 

If there isn't a built-in tool for this, would it be possible to make a block of a bunch of one-point spot slopes and you simply choose which surface & the insertion point when you insert the block?

AutoCAD Civil 3D :: Corridor / Surface Style To Display Slopes

Jun 6, 2013

I am looking for either a corridor style or surface style to display slopes while in plan view while working on a corridor. I know you can turn on slope arrows as a surface style, but I am actually looking for the grade to be displayed next to a slope arrow. Hopefully I am explaining it properly.

I just am looking for a better way to spot errors before putting surfaces into machine control without checking station by station in the section editor.

AutoCAD Civil 3D :: Different Surface Cross Slopes And Super Elevation

Mar 6, 2012

Our provincial standard requires subgrade and subbase surfaces to have a normal cross slope of -3%.  The base and asphalt surfaces have a normal cross slope for the driving lane of -2% and -5% for the shoulder.

I have been trying to figure out how to do this in C3D.  I have thought of different ways of handling this for a straight tangent, but have not tested them.  What is causing me the most grief at the moment is how to handle this in a curve with super elevation.

The transition will be different for -2%, -3% and -5% Runout distances. 

Can C3D handle this? What about using Subassembly Composer?

(I should mention that I have tried with Subassembly Composer, but I am not sure how to deal with superelevation.  -

AutoCAD Civil 3D :: Create A Label For Slopes In Cross Sections For Surface

Apr 30, 2012

I am trying to create a label for slopes in cross sections for a surface created from breaklines using gade breaks as you can not weed segment labels

I am weeding the labels out based on the change in grade of the section profile and making the label text high very small of the labels I do not want to see. But the first label returns ??? because there  is no grade coming in so I get ??? instead of something usefull like null. Any way to convert?? to something you can evaluate and use.

AutoCAD Civil 3D :: Bounded Surface Area

Nov 24, 2013

I am trying to get C3D to report the surface area for a bounded area with no success.  I am aware of the Bounded Volume feature, which BTW appears to be retired in the 2014 release (AECCCFDBADDBOUNDEDVOLUME fails to produce any results). Obviously there have been some major changes.

What I want to do is retrieve a report for a defined section of a surface, regardless, of what type of surface it is.  I see this as simple as deriving the 3D areas of the trinangles within a bounds of a TIN.

AutoCAD Civil 3D :: Surface Depth Area

Nov 15, 2013

For a surface: I would like to a boundary above a inlet point that is 3" deep.

I would like something like catchment area but the ability to specify a depth distance. Or specify a depth in the water shed analysis in the surface properties.

The only way I know to do what I want is user defined contours for each elevation. Is there a better way to do get a specific shed area for a depth?

AutoCAD Civil 3D :: Calculate AREA Of Cut And Fill Between Alignment And Surface Profile?

Aug 18, 2013

How to calculate the AREA of cut and fill analogous to the volume of cut and fill between surfaces, but instead only between the alignment and the road profile in the prolfile view. From what I've read of similar posts a few people have had the same question but have been instructed how to do it with volumes as opposed to area. Also how to insert a table of cut and fill area analogous to the one you can inset from the volumes dashboard.

AutoCAD Civil 3D :: Slopes And Angles In Profiles

Aug 31, 2012

I am using Civil 3D 2012. I am drawing a water line in a profile with a vertical scale of 1" = 10'. I am trying to draw lines at 45 deg angles to account for standard fittings.

Now, I tried to block a 45 deg angle and exaggerate the y scale, but for some reason this does not work well mathematically. Is there a way to draw lies at a certain slope, or at a certain angle from another line, while taking into consideration the scale exaggeration?

AutoCAD Civil 3D :: Use Different Slopes To Create Pond?

Apr 7, 2013

I have a surface and i have the outer border of a pond i want to create (see attachments). What makes it difficult for me is that different areas of the pond have different slopes. The area marked as "A" has a slope of 1:5, the are has a slope of 1:2 and the rest of the pond has a slope of 1:1.

My problem: I do not know how to grade the borderline so i end up having a surface with different slopes as my pond.

AutoCAD Civil 3D :: Topographical Survey That Show Different Gradients / Slopes

Feb 26, 2013

I am new to Civil3D And I am using it for one purpose, Im working at producing planning drawings for solar farms, and the client has asked to me produce topographical surveys highlighting where the gradient or the slope is greater than 15 degrees. Is there someway i can use Civil 3d to do this?

Ideally im looking at producing a 3D Model which has shaded areas for the areas which are above 15 degrees. And Hopefully another shaded for areas between 15 and 10 degrees, 10 and 5 and 5 and 0

The topographical surveys i am downloading at the moment are from a site called promap and are DSM Type?

AutoCAD Civil 3D :: Subassembly - Variable Earthwork Slopes Beyond Alignments?

Nov 29, 2013

I just want to start by saying I have been extremely impressed with the speed and effectiveness of finding Civil 3D solutions through this forum. However I do not think there is a way to solve the problem below without making a custom sub assembly.

There is a common problem that I run into when modelling earthworks on airfields. All Taxiways and Runways will have sepirate areas that determine the slope of earthworks in that area. As an example I will explain my problem for a Runway.

Any ruwnay will have a Strip area (150m offset from its centreline) and a Clear and Graded area (105m offset from its centreline). Therefore any earthwork slopes between the runway pavement edge and 105m offset from the centreline will be determined by the requirements within the Clear and Graded Area. Likewise any earthwork slopes between 105m and 150m offsets from the centreline will be determined by the requirements of the Strip area.

My problem is that when overlaying a runway, the new earthworks required may extend beyond the clear and graded area (and into the strip) at some points but not in others.

Therefore I would like a sub assembly that does earthworks at a set slope unless it passes the clear and graded line where it would then continue the earthworks using a different slope. It should be pointed out that the clear and graded line will be present along the entire length of the runway and the earthworks may or may not extend beyond it.

Just for the sake of clarity, when I say earthworks, I mean the subassembly within autocad that will "Cut or Fill" at a set slope until it reaches a chosen surface level. Similarly the "clear and graded line" and "strip line" are 2D and mearly delineate the areas in plan.

save time and make my model more dynamic. As it stands I have been getting around this problem by modelling the earthworks at the initial slope (clear and graded area) and then manually amending the corridor to use a different assembly where the earthworks extend beyond the clear and graded line.
