AutoCAD Civil 3D :: 2012 Surface Style Set User Slope Ranges

May 26, 2012

I am grading a parking lot and trying to highlight areas with less than 1% slope.

I can't find the spot to set user slope ranges in the setting tab.

I can find setting number of ranges with three options of minimal use.

This used to be so simple in LDD.

The examples I have seen for this function all show odd ranges of limited value.

AutoCAD Civil 3D :: Can't Display More Than Two Slope Ranges

Jul 8, 2013

I've got a surface that displays contours correctly. When I go to Surface Properties-Analysis tab, I can  set an arbitrary number of ranges for contours, directions, elevations, slope arrows, etc, and they display correctly.

I can set an arbitrary number of ranges in the slope range box too, but when I click the Analyze button, Civil 3D 2014 hotfix 1 only displays two slope ranges: 0% to 2979736.0077% and 2979736.0077% to 99999900.0001%. (!)

AutoCAD Civil 3D :: Slope Analysis - Ranges Set To 10

Oct 12, 2006

I can not get the slope analysis to come up with 10 slope ranges. My ranges are set to 10, but my Range details populate to 22? Screen Cap included. I've tried this with Equal Interval, Quartile, and Standard Deviation. Nothing will create 10 intervals.

My "slope analysis" surface style is set to show Slope, with the range set to 10. In surface properties, my range is set to 10.

AutoCAD Civil 3D :: Surface Slope Style Plan Read?

Jan 22, 2012

Using Civil 3d 2012, I have a slope label with mult lines, and set to plan read.

When I rotate the label, the goes to plan read, but the bottom line text is on the top, top on the bottom.

I  hope it would be simular to mirror.

I look at the expression, but didn't see any way to get the  label angles.

AutoCAD Civil 3D :: Create Volume Surface To Show Elevation Banding With Cut And Fill Ranges

Nov 12, 2013

I am working on a large park project.  I have a proposed and existing surface.  I have created a volume surface to show elevation banding with cut and fill ranges.  I need to create a drawing for someone who doesn't have civil 3d showing all the "cut" areas.  They really want a boundary of hatch.  What is the best way to do this after I change my analysis to -30 feet cut to 0 feet cut.

AutoCAD Civil 3D :: Slope Of Surface After Kriging

Apr 5, 2013

Please find the attached picture. It shows a surface with its data points. I extended the surface to the outer boarder shown by kriging. The slope of the surface that was added with the extension (past the data points) has an upward slope that was generated. I need the surface to stay level with the data points that are there.

How to avoid that added slope when extending a surface?

AutoCAD Civil 3D :: Daylight To Surface Max Slope?

Apr 18, 2012

I'm modeling a simple corridor (12' lane 2%, 6' shoulder 6%, 4:1 to match EG).  I used the "LinkSlopeToSurface" subassembly for the 4:1 to match the EG.   Unfortunately our EG isn't always wide enough for the 4:1 slope to match it somewhere.

Is there an assembly that would use 4:1 as a standard daylight slope, but where necessary adjust the slope, max. 3.5:1, to match EG surface?

AutoCAD Civil 3D :: Slope Surface Percentages

Aug 16, 2013

I am using AutoCAD Civil 3D to do a slope analysis across project locations. When defining slope categories, I am finding that the max slope percentages are astronomically high; ranges are being returned up to 360,000%--and I've only done three regions! I understand vertical slope but these percentages are not realistic by any means, especially through the areas in which I am working.

A specific example: between a contour at elevation of 792 ft and a contour at elevation of 794 ft at a distance of approximately 60 feet, the slope percentage being returned is in the 9000% range. There is not a sudden drop or rapid change in elevation between these two contour intervals to provide reason for this high of a percentage. I would expect to have a slope percentage nearer the 3% range.

The data source of the contour information is LiDAR being brought into CAD via the task-based geospatial option using MapImport. All data tables are being kept. Polygons are being imported as closed polygons. There are no surface errors being reported upon creation. The project locations were created in another program and imported into CAD using the same manner. The only thing that I can conjure up is that there is some sort setting issue.

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 :: Corridor Grading - Slope To Surface

Dec 12, 2013

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?

AutoCAD Civil 3D :: Find Path Of Determined Slope Along A Surface?

Oct 25, 2013

I am trying to draw an alignment for a road.  I want the alignment to represent the outside of the curve as the road climbs up and around a mound. Is there not way to do this in Civil 3D?

[URL]

and now I am thinking I will have to do this manually, extract contours, and trim/extend my way to victory...I really would like to have this in a dynamic situation so I can make adjustments.  Also, it would be adventageous to have the line actually follow the grade so I dont have to add curves in etc later...

AutoCAD Civil 3D :: Transitional Lanes And Link Slope To Surface

Aug 4, 2012

I am having trouble getting my assembly to work in my corridor.  I have a Basic Lane Transition subassembly with a Link Slope to Surface subassembly attached to it.  The assembly follows my centerline alignment and the lane widens as designed out to my offset alignments.  The slope grading to daylight works fine until the transitional lane starts to widen, then the slope assembly stays at the same point on the lane and does not stay linked to the end of the lane. 

I am also having trouble getting the subassemblies to attach to the proper points.  I keep trying different OSnaps unitl one seems to work, but I am never sure the subassemblies are connected properly.

AutoCAD Civil 3D :: Suppress Trailing Zeros In Surface Slope Label

Sep 24, 2013

I'm trying to suppress trailing zeros in a surface slope label in run:rise format. Basically, if it's a 2 to 1 slope, I want it to read 2:1 or if it's a 2.5 to 1 to read as 2.5:1.

I found this blog showing how to do it for line slopes, but I think it's not able to work using the run:rise format.

AutoCAD Civil 3D :: Add User Contours And Extract Polylines 2012

May 21, 2013

I know 2013 are more exposed and the .net can extract contours. However using 2012 at the moment. so my plan is using .net to add the user contours and then use com object to extract.

so far i can get the surface object and assign to two different surface variable one is .net and one is com. I am looking at the surface analysis object and can't figure out how to add contours at user elevation. it is also read only in the surface object. but i find this:

SetContourData
(analysisData()

which is obvious not read only. so any sample code of the procedure of assign user contours?

AutoCAD Civil 3D :: Shoulder Subassembly That Varies Slope In Relation To Lane Superelevation Slope

Jan 22, 2013

i need a shoulder subassembly that varies slope in relation to the lane superelevation slope. i know that i can get a subassembly for the shoulder that will follow the alignment superelevation xml data but in my case i can't use it because we are just adding a shoulder to an existing road. we're not changing the superelevation of the existing road, just milling and overlaying and widening. right now i've created a profile of the outside edge of the shoulder that gives me the correct shoulder slope but whenever i change my centerline profile i have to redo the shoulder profiles which is a real time suck.

AutoCAD Civil 3D :: Slope To Depth Of 10 Feet Than Change To 2:1 Slope

Aug 13, 2012

I am in the process of transitioning from land desktop to Civil 3D. I design roads in steep terrain and sometimes need to have my catch (daylight) slopes change. So my question is, how do I change a daylight slope at a specified depth? For example, from the shoulder of the road I want a 3:1 fill slope to a depth of 10 feet than change to a 2:1 slope until it catches the existing surface. Can this be built into a subassembly such that if the fill is less than 10 feet it will daylight correctly at a 3:1 and if the depth is greater than 10 feet then it carries the 3:1 for 10 vertical feet and then changes to the 2:1 until it daylights?
