AutoCAD Civil 3D :: Simplify Surface View?
May 21, 2013
where is the option to modify the quality of a surface tham I'm displaying?
For instance if I zoom out, it looks with less polygons, if I zoom in it looks with more polygons.
I've downloaded today some DEM Surfaces with an area of an entire city, and the civil 3d is simplifing automatically the surface... I gave a friend the same surface and on his civil 3d it works very bad without simplifing the surface at all.
I guess there has to be a switch somehere? Civil Engineer / Infrastructure of metropolitan transports [URL]

Any real good setting to edit surface in 3D. I typically just set it to shaded, and i find that i have difficulty making out details. I like to have Tins and points displayed and occasionally turn on contours. Also I hold shift and the mouse wheel to rotate the views.
Any settings they feel make it easy to tell what is going on? Or a good way to 3d rotate without having to constantly use zoom extents to find the surface?

I have my surface, I'm seeing it in orbit view mode . (also it doesn't work on 2D...)
I'd like to create a 3d Poly using some points on the triangles of my surface....
I'd need a transparent Inquiry tool , to use when I create points or 3dpols
I think it is basic....
I know _AeccFeatureElevsFromSurf
but i'm talking about a 3d Snap....
Civil 3D (2013) how much you have to improve....

I changed my Corridor Prop : From "Specific Code" : Top to Datum as shown below
and afterwards my section view Don't have the corridor in it !!
I tried to creat a new one but in the Section Creation tool i could not find surfaces :

Attached are survey points that created the surface of a road embankment portion that caved-in. The road is very near a reservoir shoreline.
1. How can a surface profile be produce? I/'ve use line to change it into an alignement and then create a proile , then a profile view. But the the surface profile is missing.
2.the points having higher elevation are the top edge( road level) of the cave-n . A few few shots were take before the shorline elevations.
3. What the best way to come up with the rock volume to fill the cave-in given this surveying points., Also the shoreline elevation will be lowered some more while work is being done since the fill is not allowed to fall in the reservoir.

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.

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?

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 have a long text (using special true type fonts) exploded using the express tools. Problem is that, for example, an "O" became made by a lot of straight lines. So my file becomes heavy weight, and that file has tube cut using a laser. So how can I simplify that text/lines?

I have an assembly that is derived from a solid body part. The assembly can rotate in the part hence the .iam that was created using Make Components also rotates. The trouble is I need to make a template drawing showing the assembly in the same position all the time.
Is there a way to make a base view always look at a surface and follow that surface so that the view on the drawing always looks the same?
For example: If I had a dice and I create a base view of the two dots side of the die. If I roll the die I still want to see in the base view the two dots side of the die in the same orientation.

So I've been creating a building and I can't seem to get rid of (or hide) the lines that make up the edges of my surfaces (or solid) in the animation view. Is this typical?
For instance, I have one side of the building that is using 4 different textures all on the same plane and they butt up to one another (example: brick meets siding). Where these two surfaces meet the lines that makes up the edges of the surface won't go away. Thus always showing white line showing the boundaries o the individual surfaces.
Can I turn these off, hide them, or am I being a total 3D Modeling noob and missing something basic?

I was wondering if after drawing an alignment, creating a profile, and profile view, is there a way I can mark items along the alignment so they could show up in the profile view. I am laying out a pipeline and want to have the profile display a marker for items such as tees, elbows, reducers and other items. The marker I would like to use will be something like the vertical style grade break markers.
Also on a side note, as each of these items will have a different name, is there a way that I can add these markers and then have each one with a unique name?

1. I had trouble with profile view of the alignment line shown. What step am i missing? Are there things that is turned off?
2. How can I best come up with the right volume to fill.
3. Do I need to learn the grading tools? or could i get buy with a section profile from the alignment. ( it is not even an alignment yet)
4. How to I render a rock fill in this cave-in.
The attached aerial image , has survey or cogo points that are imported to surface, to become surface points. . So I wanted to create a surface profile below and an outline of fill above it. Iideally the side profile would look like a trapezoid, where the base is the surface proile and top would be the design embankment.
But the reason , a surveying crew went down and took shots at the shoreline and a couple shots around the cave-in walls (higher elevation on the cave-in wall cannot be surveyed, although I coud have used a laser , did not) is so that a more accurate volume of the cave in can be obtained. I tried to label how far the road edge is from edge of the cave-in . Norice the higher elevations are the top edge around the cave in area.
The ouline for the embankment will be a mild slope then breaks to a more steep slope. like 4 :1 , then 1.5:1

I created 8 points (4 locations with 2 depths in each location) in the DWG of my AutoCAD Civil 3D 2013 project. I grouped these 8 points into 2 Point Groups: Point Group 1-high depth has Points #1, #3, #5, #7, and Point Group 2-low depth has #2, #4, #6, #8. I changed the 2D Wireframe to 3D Wireframe and on TOP view I saw Point Group 1 is on the top of Point Group 2 (because the 2 Point Groups have the same values of X- and Y-coordinates with different Z(elevation) value - see the first attached file. How can I change the TOP view to the TOP-FRONT view by using some Command to get this fixed TOP-Front view thar has the good separation of the 2 depths as shown in the second attached file?

I have been creating directly the DWG of AutoCAD Civil 3D 2013 for a couple of months.I created a project for the 8 points (4 locations with 2 depths in each location - i. e. same XY-coordinates, but different Z) And I just cannot separate the 2 "depth" points of the "same XY-coordinates" location in the 3D Wireframe by using the 3D Rotation Cube. I wonder I should start the C3D 2013 with choosing the right Template, configuring proper Viewports and creating suitable View Frames. I don't know what Template is right for my project of the 2 "depth" points of the same location in the 3D Wireframe of C3D 2013 - see the attached file. what Template (.dwt) is right for my project, how to cofigure 2 or 3 Viewports, and create the View Frames.

I was given a horizontal centerline of a 5 mile bike path. We have to stake all the even stationing every 50 feet and all the VPC's and VPT's with vertical elevation. I have created the horizontal profile and also the vertical profile including all the vertical curve information. Is there an easy way to incorporate the elevation information back into the plan view so I can create points that carry x,y & z points that I can transfer out of autocad as a .txt file so we can upload it on our gps equipment?

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.
