When you hold your cursor over a surface it will display a window with different surface elevations if there is a surface where your cursor is located.Is there a way to make it display all of the different surface elevations rather than just 6, because I have a few more surfaces that wont display their elevation. Or is there a way to set the order in which they show up? I can get to see what I want to see if I isolate the selected surfaces but sometimes it takes awhile to load up the corridors, etc..
I need to figure out a way to sample multiple surfaces for multiple alignments.
Example 1: I am creating cross sections for a river dredge showing the pre-dredge bathymetry, design dredge elevation, and post-dredge bathymetry results. I have 100's of alignments that I need to sample 3 surfaces and display in profile view. Due to the clients requirements for display, using the cross section tools don't work for me, so I have resorted to using a seperate alignment for each cross section.
Example 2: Working in a subdivision with many utility alignments it would save quite a bit of time to be able to choose a group of alignments and sample multiple surfaces in just a few clicks.
I am working on three different projects at once. For each project, I was sent a drawing with contours as polylines. Each contour is broken up into polylines about fifty feet long each at elevation 0. I am trying to set the polylines to proper elevation without editing each one individually. Each drawing contains several hundred polylines to modify. I was hoping for some sort of way to use a fence and interval (2') with a starting elevation.
I've searched the internet but haven't found a lisp routine to do this. I thought I remember Land Desktop having something like this, but can't seem to find it in Civil 3D 2012. I have found several threads asking the same question. Each time the poster was referred to a blog 7629. That blog unfortunately seems to have been taken down. If I can’t find an answer soon, it looks that my best option would be to retrace each contour which makes me glad to be paid hourly.
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.
using CIvil3D to figure volumes. I have a very large aerial topo from a couple years ago to compare against a topographical survey I completed this year. No problem creating surfaces.
Question: In the topo's, I need to get a volume from two different areas....one area being a fill area, the other being the borrow area. Don't want any volume data throughout the rest of the site.
Do I just create one large surface for each topo and designate boundaries somehow? Or do I need to create multiple surfaces for each topo? If this is the case, will I need to make sure any breaklines, etc. don't cross from one area to the other?
I am creating my Final Grading surface with from 2 surfaces - a proposed road surface and a proposed grading surface. (Note of roads within the road surface)
The issue is that when I paste the proposed road surface (that consists of several looped sections) over the proposed grading surface, the proposed grading surface within the looped road areas dissappears.
I have tried several options using boundaries for the inner looped areas on my road surface, and has altered my order of opterations for my final surface edits, and many other things also.
I have 2 different surfaces (Existing Ground & Proposed Pipe Invert) that I want to have the elevations shown for in a profile data band, but I want them to show at the design profile's PVIs (Proposed Road). Is it possible to set up a data band style that samples at one profile's geometry points but displays the elevations from these points from a different profile? My workaround is to set the data bands to all sample from the design profile first and label over the design profile's data band but I'm hoping for a cleaner solution. Attached is an image showing the profile view in question.
I have a need to find the lowest elevation inside of a small rectangular polygon (6'x7'), then assign the polygon to that elevation. This is fairly easily done manually with feature lines, however I need to repeat the operation about 3,000 times to create a design grid (therefore, not obliged to using all of the design budget to do so).
I employed the GIS department to run the analysis, which they can do, however they can't rotate the DEM grid output to match my project because it doesn't run parallel to north/south, thus skewing the results.
In highway construction, I usually check for lowest ditch elevation and see how the existing drainage flows. Typically one would create or specify in CL profile creation with a 15m offset right and left which would then generate existing CL and 15m offset profiles in profile view. However, the 15m offset profile might not represent the lowest point in the ditch as the lowest elevation offset distance varies along the highway.
My question: Is there a way in civil 3D profile creation where it can automatically trace the lowest elevation in the ditch and plot it in profile view?
. How to assign proposed elevation to layout alignment along each station?. I know there is a way in LDT to assign proposed elevations to s specific range of stations or the full alignment, under menu "profiles/ FG Vertical Alignments/Create COGO Points" I am looking for the same one in C3D.
2. How to add connecting alignment label and station in profile view. For example I have an main alignment and in-between lot of other alignments are meeting with this alignment.
I want to show in profile view of the main alignment the meeting alignment's name and the station it meets with?
In C3D 2012, when I needed to know what elevation a surface contour was at, I simply hovered my mouse near the point in question and a small window would tell me what elevation my mouse was hovering at. Now, in 2013 I am trying to do the same thing but the little window only has the name of the surface and no elevations. So, how am I supposed to know surface elevations on the fly? Is there some setting to turn that back on?
We have a good size channel and the section for the channel varies quite a bit. We want to find the volume excavated in the channel between 2 elevations (it is the area of sand per the goetech report)? A template was not used to create the channel surface, breaklines and gradings were used.
I need to project a surface/grading (or something of that nature) across my berm and have it intersect with the inside bank. This is better explained if you see the attached image. In the plan view you see 4 featurelines. Outside TOE, outside TOB, inside TOB then inside TOE. I need to project the outside TOE across the berm (shown in the section view) then create a new featureline where the line and inside slope of the berm intersect. Note that all the elevation shots vary as does the widths across the berm. What's the best way to do this?
I have two different point groups that I am using in my drawing. One is from a survey done a few years ago and the other is from one that I did just the other day.
I don't have a problem inserting the points or whatnot, but the issue I am having is that when I click "Datum" to adjust the elevations of my new point group (to make my benchmark 100.00'), Civil 3D alters all of my points; including the ones from the older survey. Is a way to adjust elevations to only one set of points.
We are running Civil3d 2012. When converting a line or 3d poly to feature line, or just creating one it adds elevation points where it crosses surface breaklines even if you do not assign elevations. We want the feature to just have 2 elevations. The beginning and end. Is this a bug? Or is there another setting somewhere?
I am working on laying out data for some survey crews along the centerline of the road. I have a BC and EC elevation, but the vertices along the CL are at different elevations, which were the original elevation of the poly line before being transformed into a 3D polyline. Is there an easy way to make the full line follow the slope from BC to EC other than manually shifting the vertices?
I graded a commercial site with mostly feature lines. I added points where I needed them to get everything to work. After modifying my surface, I suddenly have zero elevations randomly throughout my site. They don't make any sense why they appear. Some are just added to my drawing and others are existing points that were changed to zero. I can go to a back up drawing from a few hours ago and redo some grading, but I would like to know if there is a way to just erase zero elevations from the surface. I remember LDD was able to create surfaces ignoring elevations below a set elevation.
I have imported a survey file. When I insert the points into the drawing, the elevation changes to something that isn't even recognizable. When I view the point in the survey tab, the elevation is correct, when I view the point in the prospector tab it is different.
