AutoCAD Civil 3D :: How To Make A Smaller Surface
Jul 26, 2012
I've downloaded a DEM and made a surface from it creating a HUGE file. I only need about an eighth of that area. How can I crop the surface to be a smaller area? I realize I can create a boundary, but I really don't need all the data outside the boundary.... I want a smaller file so it doesn't have to create one of those *.mms files.
Surely I don't have to export the boundaried area as triangles to a regular ACAD file, then make a surface from those triangles... do I? Not that it's that big of a hassle, but seems like a roundabout way of doing things.

How can one make a survey file smaller? The current file is 11 mb with survey figures and cogo points. It takes too long to load versus simple cad. How can I speed it up?
When I exported to autocad, first it crashed, then the annotation ability seemed to be missing and the points scaled/disappearred.
Or is this how it is...

I have this contour lines from dwg file (see attached) and I am trying to make a surface out of it. Initially i thought it is already a surface for C3D but i cant seem to follow tutorials. While browsing for solutions from the Internet, it seems it is not even a contour file that can be added in C3D. what is this file and how i can convert it into a surface in C3D?

I've to make a tunnel on my project. I get some subassembly on web but all the tunnel subassemblies have the target point on Width or Offset Target and Slop or Elevation Target. I don't know whats happens but only my region that owns the tunnel subassembly isn't recognizing on corridor, and isn't drawing on my sections too.

How can I make sure the annotated surface labels spot elevations from my 3d design drawing which is being xrefed into a new Precise Grading Breakout Sheet plots screened?
The Label Style which I created for the annotated surface label spot elevations has all its properties set to be ByLayer for example its color and lineweight. The Layer I assigned the Label Style was assigned to a layer with a color and plot style that should plot any object screened. Color 8 and Plot Style Screened.
What other steps am I missing to assure myself that this Label Style will plot screened in my new Precise Grading Breakout Sheet?
I also made sure that the xref drawing in which this Surface spot elevation has the correct colors and lineweights and Plot Styles in my new Precise Grading Breakout Sheet.

If you look in the attached PDF, I have an elliptical wall that also has changes in elevation. call it a compound radius if you will. What I have to do is to make a wall cap to go on top of the wall. I know, sounds fun.....I have the surface on the right of the PDF and i need to figure out how i can take that shape and have it lay flat so that i can cut this shape out on my CNC. i know I can use the FLATSHOT command, but this will not give me the true shape of the board.

I have a huge file that I am working with. I keep getting fatal errors. I am trying to make the file size smaller. Within the file there are 1836 layers, I am trying to reduce that number greatly. There are also lots and lots of blocks. I have heard that it is possible to make all of the objects on one layer and also compress layers.

I have xref-ed two .dwg files into my drawing. They are on top of each other, and now I want to make horizontal sections from several smaller areas containing both files. However, when I do, all lines turn olive green and I loose the original layer structure (in the section, that is, not the original x-ref).
Is there a way to make these sections and keep the original layers in the sections? I'd rather not use xclip.

How to make the dimension get bigger and smaller as we “scale” the drawing?
For example, the drawing in the screenshot below is scaled by 0.5 but that didn’t affect the “size” of the dimension (height of the text, extension lines, …).
Is there a way to get the dimension line affected as we scale the drawing such that the “dimension text” and the “extension line” are increased/ decreased with the scale factor?

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 don't use Photoshop for extensive stuff, I like to make graphics for Glitter-Graphics for fun. I can't find out how to make an image smaller. When I go to the top and click on layer and try to make it smaller, it disappears althogther. How does the crop tool work? Also after I hve one picture open, if I open another the first disappears, why?

I'm trying to take a face from one picture and put it onto a face on another picture as a layer but they're different sizes. I know to use the lasso tool to move the face over but how do I shrink it down to size?

I am currently working on making a map out of a satellite image. I am stuck trying to figure out how to get text to be small enough to be legible. I have cropped and resized the original image, It is 137x224 @ 72ppi. I want the text smaller, I think I cant get enough definition because the pixels are huge, text size 7 and under becomes like 6 squares per letter and there is no definition.
The same effect is keeping me from getting well defined and sharp lines. I try to stroke a path and the line looks like a row of squares instead of a line.

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'm trying to make this picture's file size smaller. It's the startup page for my website that I'm making. The file size is somewhere around 130 kb, and it takes a while for it to load up for a website. Yes I've used Imageready, and that doesn't help a whole lot. I just want it to load up quicker, without losing a lot of quality. The website is for the Air Force, I'm joining as a pilot and am making a site documenting my growing up in an air force family, and my going in the Air Force myself.

I would like to make the dimension text smaller so that the information doesn't become so crowded. I notice that the dimensions are written like 12' - 10 3/4", with a space between the ' and the - and a space between the - and the 10, rather than 12'-10 3/4", like an old-fashioned person like me would write. Is there a way to control that? I looked into the dimension edit dialog box & couldn't see a way. AutoCAD writes them like I like.

I'm making a swatchbook (Pantone ® style), with a large 100% swatch and three smaller ones (5%,25% and 50% ink.). Right now I've got a 7x7 grid with all the swatches as I want (see screenshot), however the other 26 other pages only have the 100% swatch. Is there an 'automated' way I can make the smaller swatches in the 3 different percentages?

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.

The case is, i got a pdf file and then i am using illustrator to edit it and then save as pdf.
After that, i found that the pdf file size is quiet large. Someone know how to make the file become smaller but not using those compress software such as winzip and etc.
