AutoCAD Civil 3D :: Cut And Fill Analysis / Values Different - Corrupted Surface

Jul 10, 2012

I was undertaking a cut and fill analysis but the values were very different. Evaluating spot levels the depth was given as 1.2m but the volume surface stated it was only .6m.

After a while I noticed that the master surface had been "corrupted" duing a recovery, all definitions to the controlling corridor and other objects had been removed and a snapshot added with the description "added during recovery".

I had to remove the surface and start from scratch re-building the definitions.

AutoCAD Civil 3D :: Surface Volume Analysis

Jan 3, 2014

I have a large 200+ acre site that I have created a volume surface and analyzed it using the elevation banding with color to show different levels of cut and fill.  The owner has broken this area into 10 different irregular zones.  Is there a way to do the elevation banding of a volume surface and have it color the individual parcels.  They don't all have to be at once.  I can do each one at a time and PDF the drawing.

AutoCAD Civil 3D :: Exporting Surface Analysis

Jul 11, 2013

We have an "original" existing surface of a ditch, a massive ditch. dredging has taken place and now we have a new existing surface of the ditch. the client wanted to see the delineation between the areas that are now 3" lower, 6" lower and 9" lower (and so on). I was able to do this easily with elevation banding. now the client would like some sort of GPS uploadable based on the color map that shows the banding. How to accomplish this without having someone set there and set points along the different colors on the surface. that is going to be incredibly time consuming. is there an automated way to export the data that I am looking for?

AutoCAD Civil 3D :: Surface Analysis And Transparency

Nov 6, 2013

It appears color transparency for surface analysis is now broke in 2013.  It used to work in 2011 because I use to bring in Lidar data and run elevation analysis over top of aerial photos. I never found any type of resolution.  Is Autodesk aware and are they working on this?

This issue reminds me of the Point Cloud issue with Lidar data right after 2013 came out.  It worked in 2011 just fine and then 2013 they broke it.  After calls to autodesk support and thread exchanges plus several months of waiting, service pack 2 for 2013 fixed the lidar classification issue.

AutoCAD Civil 3D :: Surface Analysis By Elevation?

Feb 8, 2006

I've tried to create a surface analysis by using a point group reading xdata to set the elevations and when I set my surface properties to display the elevation shades it will only allow me to set the range to 5 or less. All of the other analysis settings for direction, slope, and slope arrows allow me to input the nuber of ranges I want, but I need the elevation analysis.

AutoCAD Civil 3D :: Surface Analysis Range Colours

Oct 31, 2012

Is there a way to automatically adjust the cut range colours (REDS) in the attached scheme such that the lighter colours denote lower cut depths in the same way that the fill range does (Greens)

I know they can be manually adjusted but when the analysis is run again the colours revert back

(No connection with Autodesk other than using the products in the real world)

AutoCAD Civil 3D :: Default Surface Analysis Type?

Jun 20, 2013

I am working on a commercial development with multiple large tenants with multiple standards.  To begin to verify the preliminary grading is in compliance, I use the slope arrow surface analysis type.

Due to my multiple standards, I find myself changing these values frequently.  My question : Is there a way to make the slope arrow the default analysis type when you are in the surface properties dialog box? 

I know it is not a major issue, but it is annoying and repetitive, having to go to the list box, and select slope arrow over and over again.  One workaround I have considered to avoid this maddening situation is to make two surfaces, with each criteria assigned to the surface properties and simply paste the main surface into each.  Then control which is visible based on what I need to look at.

AutoCAD Civil 3D :: Create Cut Fill Surface From Existing Surface

Mar 1, 2013

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.

AutoCAD Inventor :: How Long For Part Fill / Mold Fill Analysis

Sep 7, 2013

Okay, so it's been a while since I've done one of these, and I haven't done one on 2014 at all yet.

I've got a fairly simple part, it's about 6" long x 3" wide, less than 3/8" thick, without a whole lot of complex geometry to work with.  I've built up my whole mold for it, and that went okay, but the fill analysis seems like it's taking forever.  Like hours.  It gets to the "Fill" stage, gets just a sliver of green on the progress bar, and then sits.

Last time I tried this was on my workstation at the office, using 2013.  It didn't take nearly this long, and the part was much larger and far more complex, with a significantly slower computer.

Is something broken with this in 2014?  I guess I can just let it run overnight, see what happens in the morning ...

AutoCAD Civil 3D :: Unwanted Rounding Of Elevation Values When Exporting TIN Surface To DEM

Jul 7, 2010

My workflow consists of building a point cloud object from a LAS file, filtering it for ground data, and and building a surface object with it. Breaklines are inserted into a surface object, and then the surface object is exported to a DEM file to be used in a GIS application. The problem is that Civil 3D rounds the elevations to 1-foot intervals, even when the file is structurally floating point. How to override this rounding to get floating point values that reflects the original data?

AutoCAD Civil 3D :: Cut / Fill Surface Labels - Color Specific

Apr 29, 2013

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 :: 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.

Photoshop :: Analysis Measurement Gray Values Incorrect?

Jun 23, 2013

I'm trying to use the Image Analysis functionality of PS CS6 to obtain brightness levels from an image.
 
To test the "Gray Value" measurment, I've created 11 patches from 0%-100% in 10% increments. I used the fill tool (Shift-F5) and specified values using H=0, S=0, B=<percentage_value (0-100)>.
 
The respective RGB components of the generated patches are exactly as expected (255*percentage_value).
 
The measurements obtained through "Record Measurement", however, do not agree, with the exception of the 0% and 100% extremes, which are reported with 0 and 255, respectively.
 
Inbetween, there is disagreement which rises from 0 @ 0% to the highest (5 @ 50%) to then decrease again to 0 @ 100%.
 
Here is the series by which the reported Gray Values are too low (from 0% - 100%): 0, 3, 3, 4 4, 5, 3, 3, 2, 1, 0.
 
How come?
 
I've tried removing colour profiles (to exclude gamma encoding issues) and using different colour spaces and/or models, with no change in behaviour.
 
All my patches are pure gray so there shouldn't be any problem with unexpected colour weighting.
 
One funny observation I've made is that even though the patches are a 100% homogenous, PS reports different miminum and maximum values. For instance for the 50% brightness patch (RGB triples of 128, 128, 128), the report is MinVal=123, MaxVal=124, MeanVal=123.934809.
 
Clearly, the value for all three aspects should be the same, and I expect the value to be 128.
 
I'm using PS CS6, Version: 13.0.1 (13.0.1 20120808.r.519 2012/08/08:21:00:00) x32, on Win 7.

AutoCAD Visual LISP / AutoLISP :: Insert Block And Fill In Attributes With Var Values

Nov 4, 2011

I am using 2008 and I have a dynamic block with attributes that I want to insert with the below program and have the attritute values filled in automatically.  I have done this with other programs in the past and they worked great with literally no problems.  They were not dynamic blocks may be the reason this does not work. Why the block will not fill in the attributes like it should.  Occasionally in my testing I see a message about "units" when I am inserting the block but I have my insunits set to 0.  I have attached one of the blocks I want to use.  I am thinking either you cannot do this because it is a dynamic block or there is a new variable that won't let it work. 

(setq upisosym "L:/AcadUtilsJack/Programs/InsertIsoSymbols/ELL90BW_Flip_01" isosym "rat")
(setq upod "3" upsch "sched" upmatl "matl" uprat "400")

I found these two new variables and turn them off or 0 thinking they might be the problem???

(setvar "INSUNITSDEFTARGET" 1)
(setvar "INSUNITSDEFSOURCE" 1)

AutoCAD Civil 3D :: Corrupted Layout Tab DWG?

Jul 10, 2013

i have been working on a DWG (c3d 2012) most of the day, and sure enough, after my last edit in Model space, c3d crashed.  

i can remain in model space, but once I try on open the only layout tab, c3d hangs and crashes.  i was able to create a new layout in the command line and rebuild my layout, but i still cannot open the original tab without a crash.  i ran AUDIT and found 2 errors, but if i allow c3d to fix or delete them, c3d crashes.  also, if i run PURGE, c3d crashes.

how i can determine what is at fault or a method to maybe even isolate the problem? maybe a trick?

CorelDRAW Graphics Suite X6 :: Inverting Fountain Fill Values

Jun 25, 2013

Is there a way in X6 to invert fountain fill values? I have a design that is separated into three spot colors...a black, a red, and a white. I need to take everything that's black and invert all the values. So for example....where it is 100% black , I need it to be 0% and where it is 40%, I need it to be 60. The design has several fades and I need to maintain those, but invert them. 

I've tried the Invert tool....but it's not doing what I need it to do. Also note, that the white channel on this design, does not hold all the white info....as some of it is just a low percentage of black. 

Here's the design I'm working with, and a screenshot of the channel I need to invert as well.
