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

Found this code at //blog.civil3dreminders.com/2011/0 ... aries. html to extract all surface boundaries - something I do a lot. How can I take this code and use it in C3D 2012
Extract All Surface Boundaries
Ever want to extract a bunch of surface boundaries? I have, but I don't really want to select each and every surface. Here is some code for VBA that will automate the process.
Sub ExtractBoundaries()
Dim oAcadObject As AcadObject
For Each oAcadObject In ThisDrawing.ModelSpace
If (TypeOf oAcadObject Is AeccTinSurface) Then
Dim oSurf As AeccTinSurface
Set oSurf = oAcadObject
oSurf.ExtractBorder aeccDisplayOrientationPlan
End If
Next
End Sub

I used to have a tool (not sure where I got it from) that would extract all surface boundaries that were in a drawing but this tool no longer works in 2014 as it was written for 2012. Time/inclination to write a similar routine that would work in 2014?

C3D 2012 SP3 on Win 7 Pro:
I have an alignment with horizontal PVI points that are coincidental with COGO points. I want to display in a profile view, a surface elevation at the alignment PVI points in a band style. Is it possible to do this? If so, how?

I have a surface with several boundaries inside its extents representing areas where I do not want contours to be visible. Inside some of the boundaries (type = "HIDE") the contours do not show up, but in others, some segments of the contour lines are visible and others are not. How do I get all of the contour segments to be not visible within the boundaries?

Pasted into multiple smaller surfaces; made smaller by adding outer boundaries.The smaller surfaces are adjusted by using the Raise/Lower edit.Make a new surface. Paste all the small surfaces in together.
Now, I notice an area that was not included in any of the small surfaces, but was part of the original large surface. Somehow, this area is showing up in my final surface. So far I tried adding the polyline that forms the 'outer' boundary of each small surface also as a 'data clip' boundary, but don't see any difference. Only thing that works is delete surface point...click, click, click.

I'm making other routine and I want to check if there is some boundaries in the selected surface and in that case, which of them has the most priority.
contorno= "boundary" and exterior=SurfaceBoundaryType.Outer
I have done this: URL....
I think that the last boundary in the list is the first boundary priority.How can I get that list?

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?

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
Expression
(<[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)]>)

I am trying to create islands of surface by multiple enclosed polylines as boundaries.
Each enclosed polyline has several 3d lines as drawing objects.
After creating the surface from the 3d lines I use "Select similar" to select all boundaries(enclose polylines) and add them as boundaries using the "Show" option.
However, it is not working and I do not see the islands of a surface.

I have several surfaces pasted to make a composite surface, and a poly line is added as a none destructive boundary.
The surface looks fine on the screen, but when it is exported to LandXML the boundary is ignored, This creates a 120MB XML file, which will not load into Windes for Drainage work.
I can trim the breaklines defining each surfaces, but there is 8 models and 8 different areas to trim in this manor. This would take far too long and would also create 64 surfaces!!!

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.

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.

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?

I have some topo drawings (contours with Z elevations) and am trying to create lines representing where we did our field work. I then want to extract X, Y & Z coordinates of points along those lines (either where they cross the contour lines or at regular intervals along the lines that I create). I can create surface(s) of the topo that I have, but my questions are what kind of lines would be the best to use to represent our lines of field work (3D poly lines, feature lines, or alignments) and once I get those laid in, how do I extract the XYZ info into a text format of some kind (excel, csv, etc.)?

I just got a topographic map of some land we plan to develope, and would like to work out some preliminary earthmoving analysis.
I would like to sample that surface at very specific locations -- I could produce the required points in PNE format.
What I want is to find the way to: (1) import those points, (2) sample elevation from the surface at those locations, and (3) export the 3D poitns in PNEZ format.

I do realize this is probably a trivial matter for experienced users but I really cannot figure this one out by myself.
I dragged another GIMP image onto the main one, then tried to enlarge it (it worked) but the visible portion remains within the boundaries of the unscaled image..

I have created a surface in Civil 3D by adding contours....... Now that I have created the surface I need to Exoprt it to .sat / .stl files. But in order to do this I need a 3D Solid.
How do I convert this service to a 3D solid in order to the the export?
I have tried the thickening option in the 3D Modeling workspace but it doesn't want to accept my surface.

I have section views created from corridor model that also have had materials computed. The cut and fill areas are hatched solid and I want them set as another hatch style but after attempting to adjust the pattern it does not change. How does one change this and have it show? Civil 3d 2013 is currently being used but may have to back track to 2009.

I customized a surface style to show relative elevations, with lighter tones representing higher elevations, and darker tones representing lower elevations. With a single glance, I know the high and low spots in my project area.
C3d provides several default surface elevation styles. None of them comes close to providing the instant, data-at-a-glance information that my customized style does, which I use to design stormwater systems. Again, it's really useful to see, with one look, where the high and low spots are in my project area.
I can't figure out how to export, transfer, copy, whatever, my customized style from one drawing to a new drawing. If I want to see my customized style, I have to recreate it from scratch in each and every drawing where I want to use it.
How to transfer a surface style from one drawing to another? By the way, I tried opening up both drawings, with both toolspace/settings windows open. Tried dragging and dropping the customized style to the new drawing. Didn't work.

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.

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.

I have surface style (could be slope or spot elevation) with a 2 line component, and text component above and below the line. I'm trying to create on style for many options. I'm using c3d 2013, but moving to 2014.
I would like to do the following after placing the label:
1. adjust the length of the line component. (ex: as I rotate the lable, the length of seg 1 changes )
2. turn off one of the line component
3. adjust the angle of one of the line component.
4. when drag, the length of the line changes to a new value.
and while I'm asking, is there a way to move/rotate/drag the syle to a percise distance. I want the leader to be 1 unit long at 30 degree angle.

Is there a surface setting / style option where contour labels (elevations) will display at some specified interval as part of the surface rather than going through and adding them as labels afterwards? Seems like a rudimentary operation, where the labeling can be so scattered and random.
