AutoCAD Civil 3D :: 3D Orbit For Surface-2d Banding Too Slow
Apr 19, 2013
I have a surface volume analysis with 2D banding..Regardeless of it is a +- surface and it is not at the right height location, I want to see it in 3D. uffffff, 30 seconds waiting to acad ....
I have a good pc (wirth a superb nvidia) (I have no problems with any other software or 3D actions)
First , I have to wait almost 30 seconds before have the 3D mouse movements avalaible.
Second, every mouse move ( to change the point or view, etc ) means 3 seconds of delay.
The model is little , 400 x 600 meters. (It is an example from mastering c3d) .
I am using Civil 3d 2012 and an trying to apply elevation banding (one color) to a surface that is completely flat. Everything seems to be in order but nothing shows up. If I add another point file to it that has a variety of elevations then the elevation bands show up, if i remove it it disappears again. I can view the boundary and get elevation readings when I mouse over the surface.
Today I created a TIN Volume Surface. The volume surface seems to have a "resolution" issue if you will when displaying using elevation banding. In the attached screenshot note how the edges of the surface are "squared" or pixelated. Also, the blue lines are "hide" boundaries, and they have the same effect. I've created volume surfaces before with no issues until now.
The volume surface compares 2 surfaces that were created from nothing but contours. Some of the contours can be seen in the attached image.
I've tried REDRAW and REGEN, the image looks the same in model space and paper space, I've tried closing AutoCAD and reopening the file. I deleted the volume surface and then created a new one... I'm sure there's just a setting somewhere that I'm missing.
For comparison, also attached is a screenshot a "normal" volume surface that I created before. This one has no "hide" boundaries, but the edges of the surface aren't "squared."
I am working on a large park project. I have a proposed and existing surface. I have created a volume surface to show elevation banding with cut and fill ranges. I need to create a drawing for someone who doesn't have civil 3d showing all the "cut" areas. They really want a boundary of hatch. What is the best way to do this after I change my analysis to -30 feet cut to 0 feet cut.
Sometimes 3D orbit works perfect, and sometimes it causes a fatal error before you even get started with it. I originally thought it was just large 3D objects causing it, but now I think it's just a 2014 issue...because I've had simple 3d surfaces (3d polyline with a surface) that have caused it to crash, yet have other larger surfaces that orbit without issue. I'm mostly using it to compare 3D polylines to surfaces, usually on as built alignments that we're working on.
When I go into 3dorbit, or orbit mode, as I am panning moving around in space I can still see the points. As soon as I press 'Esc' or 'Enter' the points dissapear, how can I get them to stay visible?
I'm trying to determine a way of color banding my point files so that different ranges of elevations are visually represented by different colors. See example below that I believe was done with a different software program.
I have a surface that has Elevation Banding but I also have an air photo in the drawing. Can you apply transparency to elevation banding so that the air photo shows up.
In Civil 3D 2010, how does one output the volume of earthworks in terms of elevation bands of for example 1.5m?
Using the TIN volume surface, I've already established the total volume of earthworks (cut). However, as I have pointed out earlier, the data is required in terms of elevation bands of 1.5m.
I have created existing and proposed surfaces in Civil 3D 2008 and I'm trying to create a volume surface to produce a cut & fill map. The problem I'm running into is everything I try to follow mentions choosing Elevation Banding (2D) as the style. The only style I have to choose from is Standard. Does the Elevation Banding (2D) style normally come with the program? Or is this something you have to create?
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!
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.
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?
My 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..
I 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 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?
I have a drawing that was working fine yesterday but today every Civil 3D command takes several minutes (3 or more). I have two very small surfaces and two cross sections. I deleted 3 grading objects.I've run audit and recover, audit found some errors it fixed but recover didn't find any. I have shut down and rebooted. I just tested a similar drawing and it works fine.
On Civil3D 2007, at least on my machine, the mouse seems to move slowly when it is over the drawing space, but moves at normal speeds when over menu or toolbar items and when in other applications. It's almost as if the "resolution" of the mouse changes as soon as it is over the drawing area in Civil3D. The result is that the mouse/pointer falls behind a little bit when you move it, almost like it does when you use a remote computer over a slow network connection. This makes it difficult to have precise mouse movements.
I should also mention that I don't have this problem in any other applications, including Land Desktop 2006. Some hardware specifics: Dell, P4-HT 3.0GHz, XPpro machine, 2 gig of RAM, RADEON X600 256MB video card, single monitor, Logitech Mx500 mouse, all updates current.
