I need to export a DTM for use in another package which I previously did by Extracting the Triangles, Selecting the 3D faces & Wblocking to DXF for import to the other package.
The developers of the other package have introduced an XML import which I have been trying out but when the surface is imported into the other package via XML most (but not all) of the triangles honour the original 3D faces.
The question is therefore: Does the XML output contain sufficient information to allow the other package to "join the dots" in the correct way so as to mirror the original 3D faces and thus create an exact copy of the DTM??
How practical is it to create and manage surfaces across multiple DWG files? One of the reasons I'm asking is some of our users are insisting their work can only done in a single file, resulting in massive DWG files and naturally, Civil3D slows to a crawl. I'll admit I'm not a full time Civil3D user or specialist - thats not my job. I'm reasonably certain it can be done from the most basic of research (which apparently nobody else wants to do...), but am Uncertain what the potential pitfalls are.
They complain of slowness and are requesting better computers from IT (I've talked them down to more RAM). I'm trying to forestall a potentially nasty political situation spiraling out of control: they get better computers, others will want them as well and either get them only because of connections, or won't get them and are resentful for the perceived lack of importance. We don't need people doing 2D schematic drawings on gaming rigs.
I'm using the pointlist.xsl file and outputting in pdf.
I would like to modified the file with the following changes.
1. increase the left margin, now it seen to be 0. 2. add page breaks, it seem to be one long page. 3. add a header on each page (nu n e elev desc). 4. add page numbers. 5. have the client information fill-in using sheet set manager.
Is this possible, and where do you find information on wrighting XSL files.
I started with a points file which I created an existing surface called EG. I then used a number of feature line to create the gradings, grading surfaces and associated volume surfaces (compared to EG) also had other drawing elements and aerial photo in place. I had a lot of grading scenarios to do and it was all in one file. It was getting out of hand, so I duplicated the file, deleted the gradings (retained the EG surface) then added another set of new gradings and volume surfaces against EG. I did this in 4 files. So now I have multiple files that contain duplicates of the same EG surface and other features, but have unique gradings and surfaces referenced to those individual EGs.
Files all have similar structure:
+Various features (duplicated in all files)
- base aerial photo
- other drawing elements
+Surfaces
- EG surface (duplicated in all files)
- Grading A-1 surface
- Grading A-2 surface
- Grading A-1 volume surface
- Grading A-2 volume surface
+Site A
- Grading A-1
- Grading A-2
I recognise now that I should have data shared the EG surface from 1 file (and xrefed the other common drawing elements??) but given my situation now, what is the recommend way of putting it all together?
i'm jumping into 3d late in life...playing with volumes. i've created surfaces from aerial surveys and have saved the surfaces as separate files. i would now like to run volumes of the two as they represent the same quarry site from different years. it appears (?) i need to have both surfaces listed in prospector to run volumes. each separate file has its own surface listed. question...how do i get (import?) the second surface drawing into one of the files so i have both listed and can run volumes? i see where i can create a surface from importing a .tin file...but i don't see how to export the surface as a .tin file.
I am having a problem with my data shortcuts for my surfaces not updating. I have 2 surfaces (one ex and one prop) both are on auto-rebuild. Both of them are in separate files and data short cutted into my profiles files (I have one for water, one sewer and a third for storm drains). Any time I make a change whether I add or subtract data the file the data does not update in the profiles. As a work around I have been creating a new data short cut and adding it to my profiles files. What am I doing wrong that would make them not update?
When you paste a surface into another how does it connect the surfaces? Does it create a vertical wall where at the edge of the paste surface? Can you tell it to grade a certain slope to the surface you are pasting into?
I'm trying to create a surface under my 'existing ground' surface. There is shallow rock where one of our projects is located and using geotechnical data I want to create a 'rock surface' at the known rock elevations. I just want this surface for visual reasons and do not want it to interact with the existing ground or pipe network.
I have 4 places along the roadway where I know the rock elevations. I created new points around each known point with the same elevation so there would be more than just four points on the surface and so I could make it the width of the road allowance. But when I look back to my profile of the road, it shows the existing profile drop to the rock surface at each place that I created points for the rock elevation. Not sure how to make it so the existing ground surface doesn't pick up the new points I added for the rock elevations.
We will be doing some grading in a park with trees. Probably maximum depth or fill of 12 inches. The question has come up to be able to show cut and fill quantities as a visual shade of colors. I have a way to display cut and fill ticks and it will give me the value, but that's not what they want. I change the cut ticks to red and the fill ticks to green. What is the best way to represent this like when you turn on slope percentages and assign different colors. but I want like 0-2" fill to be red, 2" - 4" to be green, etc.
Im working in Civil 09. I need to adjust the surface I created in order for the contours to be correct. Right now I'm interpolating point elevations to adjust the contours. I find myself adding lines and adding and deleting points. It's tedious. I tried changing the grid spacing to smaller one. It didn't seem to work.
I have recently upgraded to Civil 3D 2011 when we started receiving LiDAR data. I have been playing around with the data a bit and have a few questions on how the data is dealt with. It appears that when a point cloud is added to a surface, it is using the point cloud display somehow to generate the TIN. I believe that the point cloud display is showing a percentage of points based on the maximum number of 1.5 million points. On these particular datasets (citywide LiDAR coverage, about 2,600' x 2,600' panels), we may have 4-7 million points in each LAS file. Is Civil 3D ignoring all points beyond 1.5 million in surface building operations? Also, when adjusting the slider, is there any way to know which points will be displayed...or maybe the points are reduced randomly??
I have an existing topo surface created as well as grading for a proposed elevated pad of earth done in civil 3d 2013. I simply want to calculate the cut and fill quantities. I created the grading with automatic surface creation checked on. When I use volume tools to see what the quantities are, it says 0.0 for both cut and fill.
I created another surface (TIN) and pasted the existing topo surface and the proposed grading surface into it and I couldn't get any quantities.
I created another surface (TIN volume) and set the base surface as the existing surface and the comparison surface as the surface created from the grading but again could get no quantities.
I created a grading and a surface for a pond that is abotu 30' away from a roaway that has a seperate surface. What would be the best way to connect the two surfaces? I need a uniform slope from the edge of pavement to the top of berm of the pond.
I have an oddly shapped "cut" area with various elevations that I want to create as a surface so that I can compare the volume with existing survey data. I've been able to get the basic "cut" template in 2 seperate surfaces, but now I want to combine them into 1 surface. When I paste one surface into another, the surfaces go haywire. I have attached a plan and cross section view of what the 2 surfaces (cuts) look like in relation to each other. how I could combine them into one surface and "trim" off the inside grading that overlaps..?
I have a set of sheets that have an surface (contours) on them.
When I plot them individually the surface plots fine. When I publish them using the same page setup, the surface will not plot. The contour labels do plot, just not the actual surface contours.
I've changed my workflow slightly and have created 4 junctions via the wizard but kept them all in the same Corridor (previously I kept each one in its own corridor).
I now need to create the formation surfaces for the corridor (in the way I always have done it) but only one of the junctions has a surface. I then added a show boundary and the "missing" surfaces appeared but with many connecting triangles and superfluous triangles in the curved areas.
How to get a nicely shrink wrapped surface or is it a matter of brute force removal of triangles etc?
I have created several pond embankments using the grading tools and have created surfaces using the grading groups. The problem I am having is when I turn on the triangles for one surface, I get the triangles for all the embankments and EG. The software keeps adding to the EG and doesn't cut out each embankment. I know I'm missing a step but I'm unable to find it.
I am looking for a better way to get my 3D Faces from a surface into a DXF. Note: I need to have 3D Faces in a DXF as it is the only way my data collector will accept them. My current process is 1)export surface to a XML 2) open new drawing and import XML 3)make the surface style only display triangles 4)extract triangles from surface 5)change my surface style to no display 6)save drawing as a DXF. I don't like to extract the triangles from the original drawing because I am often making adjustments to the surface and then the old extracted triangles and still hanging around in the drawing. I don't want that. Looking to see if it would be possible to record a macro(or some other automated procedure) that would allow me to extract triangles as save them in a new DXF from a selected surface all in one step.

I've created a T intersection and have created the surface for the T corridor and the entering side road. The surfaces appear correct. When I create a surface for the main road, which has been split into two regions, the surface goes thru the T corridor. How do I create a surface that simply goes up to the T intersection and picks up again after the T intersection?
Until now I have used Civil 3D for small projects. Now I'm starting a large project, 30 parcels, 5 roads in rough terrain.
Earlier I got some problems with some surfaces of the new construction that unwanted connected together. This time I want to get control of all small new "constructions" (parcels and roads) and connect them to the surface. I realize the original surface will be covered 100% of new terrain. How will I be able to connect all the surfaces together so that I can eventually create a single surface with all the new designs? (and run the waterdrop :-)
I'm trying to combine two surfaces to make one. I saw lots of people saying create new surface and paste the two in the new surface. Is there a way to create a copy besides doing the copy base, because that keeps causing my AutoCAD to error.
I wonder how to get intersection lines between two surfaces in Civil3D API. It seems that the "MinimumDistBetweenSurfaces" command in Civil3D can do this work. But I can't find corresponding API.
Using the export to DEM functionality for surfaces?
My understanding is that it is supposed to use USGS dem format, but I'm having trouble getting the resulting dem to show up intact in ArcGis. The extents are off and it chopped off the northern half of the site...?
I think this is a Coordinate System issue, but can't figure out where I can change anything...
two screenshots attached. one shows surface in CAD, the other in GIS.
it seems that there's a setting so that when it imports steps it assigns weld bead colours to all the surfaces of the imported model. is there a way to change this behaviour so that it imports with solid colour surfaces instead?
As you can see in my attachment, I have a emergency spillway coming out of a dugout wetland. The fill area, the pool area, and the emergency spillway channel are all separate surfaces. All three of these surfaces are created from gradings. The fill was a feature line drawn around the top witdth of the dam, and then graded down to the Existing Ground. The channel is another polygon feature line with elevations at each PI and then graded up to the EG. The pool was a feature line I drew around the perimeter of my pool, laid on the surface EG, and then graded down to an elevation on a slope.
I'd really like to blend all the surfaces together. Right now, they are all separated with tiny slivers of Existing Ground.
How do I go about this? As you can see, I'm still pretty green with gradings.
The issue i'm having now is that when i create a comparison surface, the tinn lines are created on the same layer as my existing surface. what's weird is that it didn't use to do this. so now whenever i try to turn off the tinn in the "edit surface style" all surfaces are either turned on or off. any way to fix this so that each new surface is given it's own display properties?
I'm modeling a couple different alternatives, and I want to make an inside mask on EG where my FG surface will be.
Is my workflow the problem, or are surface masks just buggy?
I've created three EG surfaces, EG-1, EG-2, and EG-3. I pasted the dref'd EG into each one, so now I have three copies of EG, one for each design option. Each surface is on its own layer.
I have three FG surfaces, one for each design, FG-1, FG-2, FG-3. I want to use the outer border of each FG in turn to make an inside mask for its respective EG surface. I can make one, masking FG-1 out of EG-1. When I move on and try to make the mask for FG-2 to mask EG-2, no mask is created. Is it not working because I pasted the same original EG into each of the three EG option surfaces? Do I need to promote the original dref'd EG and copy it two more times, so each mask is applied to a completely unique surface?
