AutoCAD Civil 3D :: Extract Boundaries From 2D Solid Level Band Surface Style

Jun 20, 2012

I'm using 2D solid level band surface styles when generating simple flood maps - In order to manipulate I generally have to extract the surface objects (faces or hatches) which gives me a single face or object per triangle within the surface.

I then try and get round this by using a combination of various Lisps and Union to wind up with a single boundary that I can then use in ordinary AutoCAD and 3rd party software.  However on big surfaces this is killing me as I have 50k+ triangles, so 50k+ faces or individual hatches, so its causing 15min long unresponsive stalls on my PC.

What I'd like to do is simply export the boundary of each level band to a polyline, or even better to extract the whole solid band as a single hatch object.  Is this possible within C3D as it stands, or is there a lsp out there

AutoCAD Civil 3D :: Elevation Colors In Surface Style

Jun 24, 2013

I have a surface with all sorts of heights, and want to add color to different heights. Getting the color there is not that difficult, but how do I swap them around? i.e. red is 'low ground' and blue is 'high ground'. In Holland we use it the other way around though, so blue should be low ground and red high ground. 

Where exactly do I change this? I've tried it in the surface style tab, surface properties tab, analysis tab, and some others, but no success so far.

AutoCAD Civil 3D :: Elevation Bandon (2D) Surface Style Is Missing

Apr 9, 2013

I've created a triangulation volume surface to compare two surfaces. Under the analysis tab in Surface Properties I have banded my levels in metre intervals and coloured the bands accordingly. I would now like to display the 'banding' in my drawing. Under the information tab I should be able to select 'Elevation Banding (2D)' as a Surface Style, however this is missing and I can only select 'Standard'... How to get this selection back.

AutoCAD Civil 3D :: Custom Color Scheme For Surface Elevation Display

Sep 19, 2012

I want to color cut/fill using red/greens schemes.

I want to use "interval with datum" method, and 2' intervals.

That gives like 20 rows for cut and fill, and so c3d applies one red to 5 rows, then next red to another 5, and so on.

I could pick colors by hand, but that dumb dialog is so slow, and its not easy to visually pick a nice gradation.

Is there no way to say "step from this color to that"?

Even when I do get all set up, I am finding performance of displaying the 2d solids takes forever.

I obviously have a large surface, but that is why we pay for good software right?

I am on c3d 2012 on a fast 64 bit win 7 machine. [URL]

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 :: Profile Band Style Setting?

Aug 26, 2013

In the Band Style_A pdf you can see the location of my elevation labels, they are below the bottom line of my profile view grid. In the Band Style_B pdf the labels are showing up in the proper location (above the bottom line of the profile view grid). To move the labels to the proper location I changed the "Gap" setting from 12.5 to -24. Is there a way to change this setting in my "style" rather than have to go make this change to the style every time I use it in a profile?

AutoCAD Civil 3D :: Pipe Gradient Band Style

Oct 29, 2013

I'm trying to create a profile view band style to display a gradient as a fraction i.e 1/100 rather than a % I've tried creating an expression to do this  ( see below)  the sum works but I don't get a solution/answer just the sum displayed on the band.Basically the sum is  length/change in elevation  

for clarification / = divide
(<[Pipe Start Chainage(Um|FD|P3|RN|AP|GC|UN|Sn|OF)]> - <[Pipe End Chainage(Um|FD|P3|RN|AP|GC|UN|Sn|OF)]>) / (<[Start Invert Level(Um|P2|RN|AP|GC|UN|Sn|OF)]> - <[End Invert Level(Um|P2|RN|AP|GC|UN|Sn|OF)]>)

AutoCAD Civil 3D :: Band Style In Profiles - Staggering Labels?

Dec 12, 2013

When I generate a band and the points that need to be labelled are very close to each other there is the possibility to stagger the labels (left, right, to both sides).

This works as I would expect it to.What I haven’t been able to determine is whether it is possible to adjust or influence the spacing between the staggered labels.

AutoCAD Civil 3D :: Profile Band Title Text Style

Jul 2, 2013

Is there a way to make the Profile band title a specific text style?  At the moment it seems that when I access

Profile Properties>Pick Band Style>Profile Data Bans Style>Compose Label>Label style composer

I go to the Contents (under Text) and edit it to bring up the Text component Editor.

In this if I go to the Format Tab the text style is set to annotative, however under that it says font style as an overide. How do I remove the override and set the style of the text to the text style. And how do i change the text style.

AutoCAD Civil 3D :: Super Elevation And Horizontal Transitions

Feb 14, 2013

I need getting a roadway to transition horizontally for a turn lane. If it were straight without super, it would be easy. However, the transition happens in a curve that needs to be super elevated.

I know I can use the lane transition assembly and set it to "change offset and grade" but with that, I would have to manually calculate my EOP elevations.

Is there a sub assembly with the ability to use the centerline super elevation data as well as transition horizontally?

AutoCAD Civil 3D :: Section Band Style - Design Levels At Grade Breaks - No Triangles

Feb 26, 2012

What I would like to achieve is a section band style for bulk earthworks and simple access roads that shows the design level at Grade Breaks only. The problem I am having is that Grade Breaks are being recognised as where the sample line crosses a triangle, not where the the grade actually changes/crosses a feature line.

A have a number of simple platforms, that I have created using an infill from feature lines, usually these platforms are surrounded entirely by feature lines of the same height. As to be expected, Civil 3d creates a few flat triangles, and as a consequence, all of the points where the sample line crosses these show up on my band style. Is there any way to achieve this band style?

AutoCAD Civil 3D :: Large Surface - Converting Points To Cogo Points

Mar 5, 2013

I have a large surface (over 1.5 million points and 20 000hectares)

I need to get a point file .csv from the TIN to be able to use it in another program.

-so i've extracted the points from my surface, but they are Autocad points.

-next step is to convert them to civil 3d points.

-I can not select them all when converting them or my computer crashes.

-so i select about 25 000 at a time, the converting takes roughly 10 minutes.

and i have over 1.5 million points to do.

how can i speed this up.

will more ram useful?

AutoCAD 2013 :: Display Elevation Heights Of Survey Points Without Having To Type Heights In Text

Oct 23, 2013

Any way using autoCAD LT 2014 to get CAD to display the elevation heights of survey points without having to type the heights in text bozes next to each individual point. i can insert a field which displays the elevation of the point but doing this again i would have to do every point individually.

Another words is there a way to select all the survey points required and get CAD to display a certain property, which in my case is the elevation height of that survey point, next to it? so it looks like    x 23.35  x 23.57 etc..

AutoCAD Civil 3D :: Creating Points According To Elevation

Jan 3, 2013

I have a number of 3D polylines that where exported from SDF previously created. They have numerous vertices, each one with a given elevation.

How can I create/highlight the higher and/or lower point in each 3D polyline??

A different solution would be automatically breaking these polylines in slope changing points (i.e. high or low points).

I understand that i can create points according to slope or elevation, but it has to be done manually, each poly at a time, and by tipping numeric values that i am sure that a powerfull software (as Civil 3D is) is able to calculate using the drawing information.
