AutoCAD Civil 3D :: Creating Inside Masks On Surfaces
Sep 19, 2013
I'm modeling a couple different alternatives, and I want to make an inside mask on EG where my FG surface will be.
Is my workflow the problem, or are surface masks just buggy?
I've created three EG surfaces, EG-1, EG-2, and EG-3. I pasted the dref'd EG into each one, so now I have three copies of EG, one for each design option. Each surface is on its own layer.
I have three FG surfaces, one for each design, FG-1, FG-2, FG-3. I want to use the outer border of each FG in turn to make an inside mask for its respective EG surface. I can make one, masking FG-1 out of EG-1. When I move on and try to make the mask for FG-2 to mask EG-2, no mask is created. Is it not working because I pasted the same original EG into each of the three EG option surfaces? Do I need to promote the original dref'd EG and copy it two more times, so each mask is applied to a completely unique surface?

I'm trying to create a surface under my 'existing ground' surface. There is shallow rock where one of our projects is located and using geotechnical data I want to create a 'rock surface' at the known rock elevations. I just want this surface for visual reasons and do not want it to interact with the existing ground or pipe network.
I have 4 places along the roadway where I know the rock elevations. I created new points around each known point with the same elevation so there would be more than just four points on the surface and so I could make it the width of the road allowance. But when I look back to my profile of the road, it shows the existing profile drop to the rock surface at each place that I created points for the rock elevation. Not sure how to make it so the existing ground surface doesn't pick up the new points I added for the rock elevations.

I have created 2 surfaces of a matierial that is buried, using drill hole data. I have a surface for the top, and then a surface for the bottom of this material. I then created a 3rd suface comparing these 2, creating an isopac contour showning the thickness of the material. My question is this:.....is there a way to make the zero (0) contour show up? I have a .5 contour interval, but 0 doesn't generate. Could i be missiing something in the settings?

Our company, was contracted to create a DTM of a residential neighborhood using our Lieca HDS C10 Laser Scanner. Utilizing the Leica software I was provided LandXML file that contained a 2ft by 2ft Mesh surface along with breaklines for the edge of roadway, driveways and sidewalks, which was imported into Civil 3D 2012.
Our client now wishes for us to provide them with a breakline for the crown of the roadway. My first thoughts on calculating such breakline was to set the Contours at an interval of 0.05' to identify the crown of the road, then drawn the break line along the crown based on contours.
Is there a way to automatically create a Breakline from Exisitng Surfaces?

I am working on a project, I was given a file with the contour already mapped out. I am tasked with finding volume of a fill I had to create. I made a 3-D polyline at the elevation I want my fill to start from and going down to my final grade. How can I make surfaces with my map. I do not have any files to make the surface off of. What is the easiest way I can make a layer, TIN has already been done but no surfaces are in the file.

I created a volume surface between the as-built and design surfaces, now I would like to show the points that display the cut/fill depths between these two surfaces. I tried modifying the surface property of that volume surface but doesn't seem to offer what I want.

When creating cross section views ("Home>Section Views>Create Multiple Views"), my sections are being placed at the exact boundary of the viewport (viewport is per my template).
Surely there's a way to create a margin inside the viewport.
Here's a screen shot of what I'm seeing. Notice how the dotted "Plot Area Boundary line is going right thru the left axis labels and on top of the bottom axis blue line (which means the bottom axis labels will NOT be seen).

I made a drawing of a stone floor excavation and I used 'draw inside' to delimit the excavation borders as below:
and this is what it looks like with edit contents selected:
I also wanted to carry on drawing in 'Live paint' mode to 'colour in' sections (the above is just a small section of a much larger drawing), but because 'draw inside' creates a clipping mask, this object is now incompatible with the 'Live paint' paradigm! So I thought I would 'expand appearance' to continue and this is what I get:
My question is, is there a way for me to successfully translate a 'draw inside' object to a 'Live paint group'? The above objects are just simple shapes with a single fill & stroke.

I'm having trouble creating a solid from different surfaces.
I already tried the surface stick, but it seems that it is still not a solid. (How can I check this?) The part is still yellow. If I try to apply the sculpt feature it says:
Modeling failure: A valid body cannot be constructed based on the selected inputs.
It 's a quiet complex shape. You find here: [URL].....

My question is "Can I create surfaces, profiles, & alignments using AutoCad2012?"
I know if I had Civil3D2012 I could do it, but can it be done with the Regular version I should say.
At my previous job I was using Civil3D2010 (darn economy Government job did lay offs) and now I'm using CAD2012 with new employer and I'm realizing that there are a lot of functions/commands that I don't have.

i have a road layout consisting of 3D ploylines. i want to create a surface over this layout.... i have tried but it will only seem to work on straight sections of road and not the intersections.. And i know it would be simple in civil 3d but i dont have access to that.

There are many examples of creating rectangular patterns, but not many, if any, of interrogating existing patterns.I have attached the files and a screenshot of a rectangular part inside an assembly. The part contains a rectangular pattern of holes and workplanes.how do I get hold of each proxy of the workplane in the pattern?In other words I don't know what to put in the for loop at the end of this code fragment:
If _invApp.Documents.Count = 0 Then MsgBox("Need to open an the assembly document") ReturnEnd If If _invApp.ActiveDocument.DocumentType <> DocumentTypeEnum.kAssemblyDocumentObject Then MsgBox("Need to have an Assembly document active") ReturnEnd If Dim asmDoc As Assembly Document asmDoc = _invApp.ActiveDocument Dim asmDef As AssemblyComponentDefinition asmDef = asmDoc.ComponentDefinition im occurrences As ComponentOccurrencesoccurrences.

In Elements 9 I want to select and copy a layer which is partly empty. This is to make a layer mask. The non-empty part is too complicated to select using any of the Select tools. If I use Select All, then copy and paste to a new layer, the pasted image is not in the right place - it has been displaced significantly. I am then not able to use it to create a layer mask, because it will not be properly placed above the original image. Why does this displacement happen ? Is there something I can do to avoid it ?

In Photoshop CS5, some of my rectangular layer masks are creating a lighter shadow like bandin just below the top of the mask. No effects are applied to the mask.

Since we updated to C3D 2012, our background masks are not plotting.They show up and seem to work properly in both Model and Paper spaces as well as print preview.
They do not plot whether it is selected through the MText dialog or in an Object Label dialog box.
I have made sure the draw order was correct and made sure that the "Lines Overwrite" option is selected.
This is happening on all three of our workstations which are a mix of XP and Win 7. We are printing to a KIP 3000 and I have made sure the drivers are up-to-date.

i'm jumping into 3d late in life...playing with volumes. i've created surfaces from aerial surveys and have saved the surfaces as separate files. i would now like to run volumes of the two as they represent the same quarry site from different years. it appears (?) i need to have both surfaces listed in prospector to run volumes. each separate file has its own surface listed. question...how do i get (import?) the second surface drawing into one of the files so i have both listed and can run volumes? i see where i can create a surface from importing a .tin file...but i don't see how to export the surface as a .tin file.

I am having a problem with my data shortcuts for my surfaces not updating. I have 2 surfaces (one ex and one prop) both are on auto-rebuild. Both of them are in separate files and data short cutted into my profiles files (I have one for water, one sewer and a third for storm drains). Any time I make a change whether I add or subtract data the file the data does not update in the profiles. As a work around I have been creating a new data short cut and adding it to my profiles files. What am I doing wrong that would make them not update?

When you paste a surface into another how does it connect the surfaces? Does it create a vertical wall where at the edge of the paste surface? Can you tell it to grade a certain slope to the surface you are pasting into?

I'm now using a different computer. I have a drawing with an existing surface and contours. I have two buildings on site that I'd like to mask the contours that run through them. I used the mask feature for one of them, but that is the limit. How can I mask the contours so they aren't running through the other building.

We will be doing some grading in a park with trees. Probably maximum depth or fill of 12 inches. The question has come up to be able to show cut and fill quantities as a visual shade of colors. I have a way to display cut and fill ticks and it will give me the value, but that's not what they want. I change the cut ticks to red and the fill ticks to green. What is the best way to represent this like when you turn on slope percentages and assign different colors. but I want like 0-2" fill to be red, 2" - 4" to be green, etc.

Im working in Civil 09. I need to adjust the surface I created in order for the contours to be correct. Right now I'm interpolating point elevations to adjust the contours. I find myself adding lines and adding and deleting points. It's tedious. I tried changing the grid spacing to smaller one. It didn't seem to work.

I have an alignement to which I have applied superelevation.
The superevation has been applied and the alignment has been annotation and it shows the change from camber to superelevation on the curves.
However when I create a surface of my corridor it does not show the superelevation, the surface is showing a cambered alignment throughout.
I have created a new alignment, a new corridor and surface and still the same.

I have recently upgraded to Civil 3D 2011 when we started receiving LiDAR data. I have been playing around with the data a bit and have a few questions on how the data is dealt with. It appears that when a point cloud is added to a surface, it is using the point cloud display somehow to generate the TIN. I believe that the point cloud display is showing a percentage of points based on the maximum number of 1.5 million points. On these particular datasets (citywide LiDAR coverage, about 2,600' x 2,600' panels), we may have 4-7 million points in each LAS file. Is Civil 3D ignoring all points beyond 1.5 million in surface building operations? Also, when adjusting the slider, is there any way to know which points will be displayed...or maybe the points are reduced randomly??

I have an existing topo surface created as well as grading for a proposed elevated pad of earth done in civil 3d 2013. I simply want to calculate the cut and fill quantities. I created the grading with automatic surface creation checked on. When I use volume tools to see what the quantities are, it says 0.0 for both cut and fill.
I created another surface (TIN) and pasted the existing topo surface and the proposed grading surface into it and I couldn't get any quantities.
I created another surface (TIN volume) and set the base surface as the existing surface and the comparison surface as the surface created from the grading but again could get no quantities.
