AutoCAD Civil 3D :: Rounding Of Values
Dec 10, 2012
I have 2 surfaces that I am sampling and have the bands depicted in the attached. I would like to have all bands with 1 digit of precision and the values in the Cover Depth band add up. The Cover Depth is supposed to be subtracting the two but is often off by one digit. I have tried changing the rounding options in C3D but there is always disagreement between the data in the bands.
I tried searching for this issue to no avail. Perhaps I need to have an expression to do the rounding is what one case eluded to. Seems that C3D may use a type of rounding that rounds to the nearest even number?

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?

Is there a way to have no layer value set for the description keys. I set all the layers, and now I realize I'd rather set this to no layers (boxes are all unchecked). I'd rather see no value under the layer column, but there doesn't seem like a way to set this.

I have a problem where the Inverse Report is returning values of "N 89-59-60 E" instead of "N 90-0-0 E".
I have attached a screenshot. A simple rectangular parcel rotated 1 degree.
The head of our survey department is going nuts trying to check things.

I think you will see from the pic my line mabel do not = the distance or property mesurement. all the labels are truncated so there is no auto rounding..

We sre doing 3 line profiles for a road and the left and right curb should be .13' lower than the centerline elevation. In many cases we are getting .14' or sometimes more or less. We tried resampling the cooridor with a tighter interval but still the same results.

How do you set an object's annotation, say a line, to display a line's angle or bearing precision to the nearest 20th second.
Kinda like this for decimals:
0.000
0.00
0.0
But for degrees minutes seconds.
Also, I will require the seconds to hide if the nearest 20th second was a 00. I also need a leading zero for minutes if the minutes was under 10 minutes.

I have an attribute blocks and this att block has two tag values , is there a simple code for to change 1st tag values automaticly according to 2nd values ?
for example :
1st tag (50x50) - 2nd tag ( 100 ) ==> 50x50-100
if i enter 201 valuse to 2nd tag then 1 st tag has to change as 100x100
if i enter 501 valuse to 2nd tag then 1 st tag has to change as 150x510
I attached a jpg file for explain much better

I have a section of road that has super elevation from -6% to +6%. The asphalt layer (top green) supers from -6 to +6 but the base course (red) only goes from -4 to +6. I attached a sketch for some visual information.
What subassembly recommended for this scenario?
Is there a way I can set max values for the subgrade? Or an assembly where I can use superelevation for the top and for the subgrade?
I am using C3D 2012 but can use 2013 if it makes a difference.

Attached are two files: 1 file has 0 values on the volume table, and the other file has Sample line group Properties.
Surface 3 is the surface that has the existing actual survey points . Do I have to pick another surface : the other two are the surfaces I created in the Corridor as surface boundaries , Top and Datum

is it possible to export elevations from a surface at a given interval? i can easily export all the data i used to build the surface, but now I am wondering if its possible to export/extract the surface to a CSV or TXT file with a position and elevations, say, every 5 feet?

What is the best way to insert a c3d point with assigned values. For example, I want to insert a point with the style curb stop, on a certain layer with a certain label. Going through thr insert point tool is not very user friendly for users looking to add points, not assign properties. Can this operation be added to the tool palettes? I am not familar with creating my own.

C# public bool FindStationAndElevationAtXY(double x,double y,ref double station,ref double elevation)
I don't understand this method. API documentation says that "Finds the station and elevation values at the given X,Y coordinate." but this method return a bool value.I don't understand neither "ByRef".

I am creating some simple grading objects from feature lines. I am targeting my existing ground surface with a 2:1 fill slope. My resulting surface shows me 5' contours, which I think should all be spaced out at constant 10' offsets, but they are not. When I measure the offsets I get different values ranging on 10.2' to 9.7' (depending on the section of the feature line I am looking at). How to make the slope build properly with a true 2:1 offset between contours? What good does this grading tool do if you can't get a properly constructed slope?

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.

I have learned the hard way that Civil 3D has a Curve Tolerance value that is to be used when applying sample lines and computing average end cross section volume calculations along an alignment with a curve. How I discovered this was by double checking my self and using a straight alignment verses an alignment with a curve. When using the alignment with a curve the average end cross section volumes differ. I did some reading in Autocad help and it mentions that sometimes a curve tolerance value is needed when using curves and this value is changed in the compute or edit materials window. What is a curve tolerance?" The edit materials window prompts a user to enter a Degree value. How do I calculate this curve tolerance value? I assume it is related to one of the values of a curve.

I'm trying to show, using the eyedropper tool, the actual values of pixels in an 8-bit grayscale image (Mode command confirms that's what's there). In the Info panel, the eyedropper tool displays percentages for every type of color information (K, CMYK), while the "8-bit" field remains blank.

I'm getting unexpected results using "round( )" in the parameters table. File attached (Inventor 2014). Details below.
width = 35.125
end_result = round(width)
Nominal value for "end_result" is 35.039370. Why is this not rounding to exactly 35?

Autocad appears to be seclectively rounding this dimension. Both are the same DIMSTYLE, but one is rounding down, and one is rounding up. They are in the same drawing with the dimension taken on the same two lines.

Any information about using the floor command within iLogic. i have written the rule ok and it does not come up with an error. However the rule doesn't actually activate, as the component pattern it is set to gives it 7.6 ul. Inventor then automatically rounds this up, the floor rule should counteract this but does not.

How can I round drawing dimensions modulo five, keeping them dynamic?
If I have length equals 203, I can get rounded length 205. Besides, having 206 - getting 210.
If in model length changes to 313 - I'll get 315, when 316 - 320.
Probably, I should override value, using VBA. Are there other abilities?

With using superelevation wizard in Civil 3d 2012, changing the lane width is not affecting the resulted values of transion length and run-off length, Is that correct ? ( as civil is using standerd AASHTO tables which assume that lane width typically is 3.6m )
Also, There is only 2 tables for 2-lanes and 4-lanes roadway, Is it for total road width or for one directon only, and what about different no. of lanes ?

Copy a corridor successfully? I'd like to try this just a little worried about the explosion of evil this may cause to my Civil 3D session.
Even all the properties of the corridor setup from one to another would be useful. I'm building one corridor and an 2nd one that matches everything except I need to replace my Assembly with one meant for stripping.

One of the users on mCADForums discovered this bug.
"I have a value of 3516.41mm and I want to round it to the nearest whole number.
I have tried to use the round command and it seems to round up to the nearest 10 so 3516.41mm would round up to 3520mm. So how do I get would I go about rounding to the nearest whole number?"
I suspect this is due to Inventor's internal units being cm. However as we specific "a" to be in mm and "b" to be in mm this should not be happening.

I'd like to create a lisp that would check my drawings for stray vertices (I only draw in full measurements per UCS), and automatically round them up to the closest whole value, or at least mark them up in circles for manually fixing them.
