AutoCAD Civil 3D :: Adding Building Levels To Existing Ground
Oct 12, 2012
I have an existing ground surface with all different z co-ords and im trying to add three proposed buildings to my exisiting ground with all the builidngs having a level of 32.5 as a minimum, however at some points the ground is higher than 32.5 and I only want to raise my existing ground to 32.5 within the proposed buidling layout if it is below 32.5 as im doing a flood calculation. What do i need to for this?
I'm trying to create an all new existing surface over existing ground. I have a TIN surface of the EG, and I have drawn overlay splines that describe the new surface, but how to go about creating that design surface.
It is a compound surface, open on one end and closed all around on the other, somewhat like a half of a football stadium, but with an irregular upper edge because I am needing to figure out cuts and fills to manipulate the EG into this new surface without costly major terraforming. There is about 40-50' vertical elevation between the "field" and the upper rim with a generally constant 7-10 deg. slope all around. I'm just at a loss to figure out how to approach this project, and am quite new to Civil 3D.

I have a rather large project for a roadway reconstruction. Therefore, the existing utilities are in a separate drawing and the existing ground surface model is in a separate drawing. All the above surface items (curb and gutter, asphalt, concrete, signs, sidewalks, landscaping, etc..) are in the master drawing. I then xref'd in my utility drawing and though I would use data shortcuts for my existing ground surface drawing. I took the surveyed triangles (3d faces) from our raw survey drawing and copied them into my surface drawing, created a surface from the triangles, created a boundary and such. So far everything is good. I created the working folder for the data shortcuts for this project and saved the drawing and closed it. I went into my master drawing and clicked on "Create Reference". I did not promote. The reference came though and everything is fine. Now I want to add contour labels in my surface drawing which I did but they do not show up in my master drawing but the contours themselves do. Do I have to promote this drawing into my master drawing so I can create the contour labels in my master drawing? I guess that is fine but the issue is we have small areas of topo that will be added as needed down the road. If I promote the surface drawing into my master drawing then when I add topo to the surface drawing, it wont update in my master drawing.
While I was out, my partner somehow now has two existing ground lines in my cross-sections. ####exist and ####exist (1). They are offset by about .5 feet left to right. Where do I remove the surtface ###exst (1) from the cross sections. I am looking now.
I've worked with LDD for 11 yrs. Last week the IT guys changed my PC to Windows 7 64bit, so I can't have LDD and I have to work with C3D. so I am following software tutorials.
Corridor is created with daylights ,but I don't see existing ground in corridor section editor.
There is nothing about this in tutorial. Also I don't know how to calculate the volumes, in LDD after this stage we could calculate the volumes. i think in C3D I should do more for calculation.
How to prepare for rendering Existing ground with cutted corridor river? Specially in places where corridor river is below EG. If there is some tool like cut?
I have an existing ground profile, and a design profile. All I want to do is label the slopes of the design. When I click my line label style and turn on the text it labels the existing ground and the design ground. I cannot find the setting in my two profile styles to turn the slopes off in the existing ground.
Oh, how can I get a tick on the V.C. dimension line?
I am trying to label existing ground & profile grade on my cross-sections the way old Land 4 used to do it. I've muddled through section view property style settings, band settings, group properties w/no luck. It can't possible be this difficult. What am I missing?
When working with multiple building pads and configurations change rapidly. Is there a method to add a Block or Xref into a Civil3D Surface under Drawing Objects? If so, how could you do it.
I want to have a building block type 1 that I can update the block or xref then updates the surface rather than doing each one individually. The Block would have a FFE of 0.00 and then the stoops, etc would either be a 0.1 drop or so.

I was wondering if it is at all possible to add a polyline to an existing alignment? The purpose of doing so would be to extend the alignment so that I can display the proposed kerb and gutter.
I have an existing alignment issued to me which has been created using all straight lines even where there should be curves. I am trying to insert curves in these areas. Using free curves (2 entities and a through point) I create a curve then somethings happen I can't work out -
1. The curve is created but the original straight linework stays. I would have thought the original linework would automatically delete. See attached pdf between points 60 and 62 the curve and straights can be seen. 2. Then all stations after the curve are changed to the question mark symbol. If i click on the alignment all the grips are still there for the full length of the alignment, indicating the alignment is still in one piece. 3. If I try to create another curve further along the alignment it won't allow it. Stating on the command line "Selected entity must be part of the main entity."
I have one surface "EG" and two alignments, I'll call 1 and 2. The profile view already has the alignment 1 surface projected on it. I go to profile>Create Surface Profile and select alignment 2, Surface EG, go to ADD it but the profile list is empty. Shouldn't it already be populated with alignment 1 and all I'm doing is adding 2 to it? Both alignments are in the same site.
I am in the process of creating the cross section sheets and including them to an existing sheet set manager. When I try to create them I get an error saying "Sheet Set not created" which is odd because I selected add to existing ssm. If I save and exit out of the drawing and then get back into it, the sheets are created correctly in my layout tabs, but aren't added to my ssm.
I need to swap my level 1 and level 2 of my building's floorplans. What is the most efficient way to take the walls etc. from level two and place them on level 1, and take whats on level 1 and place them on level 2? I am swapping the floorplans.
I have created an existing ground surface...also 2 surfaces from corridors...one a road and 2 a berm. How do I merge these and get final contours of the proposed site after construction?
I have 3 profiles that I've superimposed together. Then I created sheets using the superimposed profile. I used the wizard and had Civil 3d do it for me (2012). Now I have to add a 4th profile to the mix and get it to show in my profile views that have already been cut. The data is shortcut into the drawing with my cut profiles views. How do I get it to be in the cut profile views without re cutting everything?
I am modifying topography to include multiple building pads at varying levels and also including sloped pads. I am having a non-consistent problem at the common boundary of some pads. A small sliver of topography sometimes 'sticks through' the common boundary. The height it sticks through seems arbitary, sometimes to the height of the original topography when cutting and sometimes much higher. I have used the copy/paste aligned commands to ensure the boundaries are exactly common but this does not work.
I have read that some users cut the topography globally and then build up the various levels and ramps using floors and the variable floor thickness command. This seems a bit cumbersome and I imagine would cause problems when cutting sections etc.
Sometimes I'm unable to place a truss in my building. When I am able to get it in, it's never at the right height (either too high or too low). I've tried moving it in an elevation and section, but it will only move left and right, not up and down. My teacher said something about changing the view range, which I did.
i have an office building designed in Revit and i want to put a Fascia around the top- it just will not work for me!the same to the roof- i want a flat roof, so i did a roof by extrusion and it asks me for workplanes etc?then it tells me this:Extrusion roof sketch must be open. The roof's thickness and material composition are defined in its type.
We here at work have recently implemented using the survey database feature in CAD as a better way of manipulating and organizing points in our drawings. However, we have begun to notice a few issues with how the survey database imports points (?).
Sometimes, and I say sometimes because it is very sporratic, some drawings exhibit the issue and some do not, the points will be skewed off the linework (we are converting existing projects to the survey database). In these situations I find that the Northing and Easting don't match the ascii file it was imported from, instead the "Grid Northing" and "Grid Easting" do. Also, some drawings will have a slightly different Grid Northing and Grid Easting vs Northing and Easting, whereas some drawings will have the exact coordinates for both sets of fields. I believe the issue is one and same.
Our points handling goes like this, Data Collector--->TBC (where ground to grid and scaling is performed)---->exported to ascii file------>Imported to CAD.
This is very confusing and irritating at the same time, and really counterproductive to be troubleshooting why our points keep moving. Redrawing the linework is NOT an option, we'll sooner go back to simple ascii file imports (where the problem is NOT present) then have to redo all of our work on our projects.
I need to extend the existing ground profile. I previously had stopped the profile at 25+00 as shown in the attached. However, I need to add on another 100' to 26+00. I can only view info in the Profile Properties. I can't change the end station.
Previously in LDD when I had a project i needed to transfer from grid to ground I could simply create a block of everything. Scale the entire block from a mid point of the site, explode the block, run check points and done.
Now in C3D 2012 when I explode my block it changes my elevations too. Yikes!!!! Luckily I had a copule of points
elevations labled and I noticed the new "Feature" of scaling my elevations too.
My site is 4,500' across and grid to ground changes it 0.32'
I'm having trouble adjusting the levels on a layer after I've previously added noise to it. Basically I'm trying to add a simple snowstorm effect to a painting I'm currently working on.
The way I normally do is: create a new layer, then fill it with solid black, after that I go to filters>noise>add noise, then I add about 150% noise and check monochromatic, press ok, after that I go to image>adjustments>levels and adjust it so it leaves only a few white spots and then I press ok, but this time nothing happens after I press ok in the levels window and the image stays the same.
How can the cross sections be setup to label the existing and proposed grade at the centerline of a cross section, see attached. Could do this in LD but have not been able to figure it out in Civil 3D

I have cut a ground line in profile view. Is there a way to "mask out" a portion of the ground line in the profile? I need to detail some stair but the surveyors only shot the top and bottom tread. I don't want to add points to the surface, I just want to draw the steps in and place them in the correct profile location. And I don't want two horizontal alignments.
