Im working on a grading plan and want to consider raising the site to cut down on my export of earthwork. What I would like to is take my PROPOSED SURFACE A and copy it along with the grading features to a NEW SURFACE B. This way, if B doesn't work out, I can go back to A.
Im assuming I need a new surface and a new site?
I often have to do storm pond surfaces that (for the purposes of planning) are flat on the bottom. These surfaces are created from a combination of survey data and grading groups and the tin of these surfaces is perfectably acceptable. However, when contours are shown, the flat bottom is shown with contours jig-jagging all over the place.
The attached image shows a comparison of the same pond. The top was created with survey data and grading groups; the bottom was created using contour data only. The generated surface on the top shows the bottom contour going in different directions and has parts where the an expected contour is missing.
How to correct/manipulate the surface to show a proper flat surface?
Has instances where you set your tolerance for the maximum triangle lenth to say 50m to reduce the amount of triangles along the edge that run at long distances. When I do this I end up with multiple surface holes and I'm not sure why as there are points in the area.
I thought well maybe it's because i should've reduced my max triangles first then added breaklines. Would this matter? I also thought I could add a line to the surface to fix the holes vs. deleting surface lines along the entire edge of a surface for many many miles.
I am trying to add points into a surface. I have done this before without any problems, but now I am having issues.
When I ID points which makes up the surface it gives me the correct Z level e.g. 24.5m, however when I hover over the surface it shows me the surface name and a different z level e.g. 0.65m. What is the reason for this difference in z levels? I think this may be causing the issue I am having when I add new points.
I select the surface and use the 'edit surface command' in the ribbon, choosing add point.
When I add a point at the level I require(23.89m), it puts it in a lot higher than the surrounding area, so I tried to put the point in to the lower z levels (0.4m) it puts it in a lot lower!
My goal is coming up with the volume bounded by the design surface and the existing surface. I don't have the design surface modeled yet.
Do i need to create alignment offsets?. Alignment 1 profile view is also attached. Then Alignment2.
What about starting with alignment1 profile view? Since I have created a polyline as the design profile ?
how do I shrink labels? Where is it in the settings ; the Align folder had been check.
I am issues with DEM files that I am downloading from the USGS website.I download 24k, elevation for the area I need. I then choose staged 1 second, add a surface to a blank drawing, then upload the DEM files to the surface.
The surface imports correcty, but when I try to import points taken by a surveyor on the same drawing, they plot incorrectly.The DEM surface and the points from the surveyor do not correspond. Also, the DEM surface is in meters, not feet. I have tried changing drawing settings, datum types, coordinate types, etc.
Is there any way to change the referenced surface on a Surface Elevation Label. I can see the surface in the properties but cannot change it.
C3D 2011
I have a project involving 3 programs. I am creating a planned development in 3d to be 3d printed when finished. The project is a 5 acre tract containing 8 buildings. I have built the surface in C3D and each building in Revit. The buildings are not in the same Revit file. For my solid work, I will bring the files over into 3ds Max Design to section into smaller quadrants to build in the 3d printer.
The questions:
Would it be better to import the surface into Revit to merge surface and buildings together?
Would it be better to import the buildings into C3D to merge entities?
Would it be better to bring those entities into 3ds Max and then merge them into one? Will 3ds Max Design allow me to insert entities accurately in the environment?
I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.
i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline. This seemed to work, but when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.
Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.
The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.
I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.
1. Novapoint is quite unstable and crashes alot
2. You cant create profiles out of 3d faces
3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface
4. A large surface made out of 3d-faces demands alot of computer power
So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.
all of a sudden whenever I run audit on my corridor file the surface definition becomes a snapshot. To add to the drama, the corridor surface will not paste into an empty surface. Why?
View 2 Replies View RelatedMy problem added with pic ... I want to make volume calculate for sample road project. When I try to compute materials I cant use Corridor surface for DATUM... There is only target surface on option..
View 2 Replies View RelatedI am trying to visualize a road project. The problems is, whenever the corridor surface goes below the EG surface (when the road is in cut) the EG surface is the only visible surface.
I sort of need to subtract the corridor surface from the EG surface, or merge the both surfaces into one.
I was wondering if there is an easy way to trim one surface to another. Right now, I have two slopes (3:1) that are perpendicular to each other. They meet at a corner and I have extended them past each other so that I could see the intersecting edge. Now I would like to trim them to each other like you would a polyline etc... but I am not sure how to do this.
If I select surf trim, it tells me they are the wrong object type, but they are tin surfaces?
I am a surveyor who wants/needs to perform survey adjustments on our data and from what I can tell this will require us to use FBK files generated from our TDS RAW files. Easy enough, but I am running into problems during import because when our field crews shoot a bad point or need to fix a point code they will overwrite the "bad" point with the "fixed" one.
when I go to import the points via FBK apparently the system doesn't realize these points were overwritten and I get duplicate point errors. This in itself isn't that big a deal except that I am only given the option to ignore the duplicate point (no overwrite, renumber or anything) which leaves me with a bunch of bad points, bad codes, etc. Sifting through the fbk to find the problems has proven dificult and time consuming.
Is there any way around this problem? we can bring our RAW files into other software (Carlson Survey, Trimble Business Center specifically) and everything works fine but we would rather not use extra software just to do survey adjustments, which C3D seems apparently capable of.
I had a few problems moving a project from 2012 to 2014. After a couple of tries I got everything set except the main alignment. When I originally used the Data Shortcut Editor to change the path of the shortcuts. I noticed that most of the paths were mostly UNC paths. So I replaced them with the current UNC path.
Now when trying to fix the one shortcut I've noticed that there is now a duplicate of the UNC path shortcut and one using the pathed network drive. So there is now a total of 3 references for each shortcut. I don't know yet if this is part of the problem but it doesn't look like it's a good thing.
My first inclination would be to delete all but the newest XML file for each reference.
Somehow I copied something and now when I open my drawing I have deplicate pipe networks with one being named something like Pipe Network and the 2nd being named Pipe Network(1). Pipe Network(1) does not show up in the toolspace. It has duplcated every pipe network in the drawing. I deleted all the pipe but when I close and reopen the drawing it comes right back. I've attched a pic. The single line is the original, the double line is network(1).
View 6 Replies View RelatedNot sure if this is something that has been going on a while, if it is a design flaw, or if it just a workflow thing that we should be more mindful of, but here goes:
1. I data reference an alignment into a drawing.
2. I later data reference in a profile that was created from and associated with that alignment.
In this scenario, Civil 3D creates a duplicate alignment for the profile i.e., the orginal alignment is in prospetor as 'Alignment A' and the profile being data referenced in creates a 'Alignemnt A (1)' duplicate and associates itself with it.
This also happens if I bring in a different profile created from the same alignment IF the alignment was already present as a data reference in the drawing.
This seems wrong. It doesn't do any of this if I data reference the profile in first...
For some reason I have three copies of my point groups. I have not inserted any drawings into my current drawing. Just been working with pipe networks. There are three copies of every point group even though only a couple of point groups are being used in this drawing if that matters.
View 6 Replies View RelatedI am trying to duplicate a feature line report I did a while ago. It has offsets,elevations,eastings and northings. What I would like is the offsets shown. I am in toolbox, reports manager, corridor, Feature Line Reports. When I create a report I get the list of feature lines which shows point codes which are back_curb,etw,...etc. When I create the file, all I get are the point code such as Back_Curb Left which shows the station, easting, northing and elevation. How do I get those offsets?
View 2 Replies View RelatedFor some reason my drawing had created several duplicates of my grading critera. For example, my drawing has the following critera:
Cut to Surface
Cut to Surface.1
Cut to Surface.2
Cut to Surface.3
Cut to Surface.4
I did not create all these criteria, they just appeared one day. The problem is that I can't seem to be able to delete the duplicate ones. I get an error saying that the criteria "is currently in use, so it can not be deleted". I have deleted all the grading in my file and I still get this error. I have tried RECOVER and AUDIT several times with no luck.
I do know that tere is supposed to be an algorithm in C3D that will recognise when two geometry points are coincident on a profile view...that is, say a profile vertical geometry point happens to occur on a major station (for example).
I have never seen this actually work. When I have this situation, the labels stagger and I get two columns of identical data on my PV.
I know I can remove individual labels bY CTRL+select and eIther erase or turn visibility to false, but I would rather that C3D figured it out for me and removed the duplicate data.

Where is the command delete duplicate objects in AC2012? In version 2011 it was in express tools. Whether this command is not in version 2012?
View 2 Replies View RelatedC3D2012. We have a master C3D template that includes a number of point filters (let say 20 of them) and a number of layouts (again, let say 20 of them) to accommodate our two sheet sizes.
Here is the issue that I am running into, when the Plan Production tools use a layout to create plan and profile sheets from the same master template that is used to initially create the file, the whole process will duplicate each point group 150 times for every group (see attached). So, what I ended up with is 20 point groups X 150. In my example, I ended up with 3000 duplicate point groups.
The end result is a file that is somewhat unusable do to the number of point groups. The other issue is now that all of these point groups are in the file you are unable to delete them all at once without "crashing" C3D. So you are left to deleting a handful at time. It is also best if you turn UNDO off while you do it.
I have been able to duplicate this in multiple files; however, from the same master template. As a test I did create separate templates (which are pretty bare bones) for the plan production and all works well. Therefore, there is either an issue with C3D and Plan Production and point groups or it is our template.
I would really like to nail down (as best I can) what is generating the 150 duplicates/ point group name to see if there is a way "around" this.
Currently, I am unable to share the template, but it shouldn't be too difficult to re-create. Take any template, add some point groups to, add a plan and profile sheet to one of the layouts, create a new file from this template, finally create plan and profile sheets from the layout in the very same template.
I used a 2d polyline to create a surface boundary for a surface created. The polyline is a closed loop. For the boundary type it is outer, unchecked Non-destructive breakline, and mid-ordinate distance = 1.
My problem is that when I do this I only get a small portion of the surface to show up within my surface boundary. If I don't have a surface boundary the entire drawing surface shows up no problem.
The purple polyline is my boundary and the light blue is the surface created within the boundary.
Is it possible to export created surface from civil to revit architecture? If yes , How? And if its not possible - maybe i can somehow import cogo points to revit?
View 6 Replies View RelatedI'm working on a grading plan which excavates down from just outside the waterline of an existing pond. When I create a surface from the grading, it looks like a whole bunch of strange break lines have been added, messing up the surface. I thought it might be the mid ordinate distance but changing that doesn't seem to fix it it. Interestingly, when I grade from the original waterline, this doesn't seem to happen.
Here is my workflow, a picture of the result is shown below.
1. Turned the current waterline into a feature line.
2. Created new feature line by offsetting outside that feature line by 3.16 ft.
3. From new feature line, grade down 10 feet at 3:1
4. Create new surface using grading.
The grading lines (shown in white) look correct. But when I create the surface (green and yellow), it is all messed up.
If I change a point or link code in one of my subassemblies, is there a way I can build my top surface using those?
