AutoCAD Civil 3D :: Spanning Pipe Labels Calculating Incorrect Slope

Oct 30, 2013

I notice issues using spanning pipe labels for the first time recently after having used them for years.  The slope calculated by the spanning pipe label is completely wrong.  I've attached a picture in which Labeled two pipes connected by a null structure.  The two labels on the bottom are the pipes labeled individually at 3.53% and 3.34%.  When labeling them as a spanning pipe, if I choose the downstream pipe first and them the upstream pipe it shows me a slope of 0.48%.  If I choose the upstream pipe first, then it gives me 2.88%.  Either way it's wrong.

As I was writing this I decided to check and see if the pipes were flowing the same direction (Start to End or End to Start).  Turns out they weren't.  After flipping one of the pipes around so that they both are laid out in the same direction (Start to End from Upstream to Downstream) the label now reads 3.37%, which is correct.

Seems like an the label should honor the flow direction of the pipe, no matter if they have been laid out in opposite directions or not.

AutoCAD Civil 3D :: Calculating Average Parcel Area

May 16, 2013

Any quick way of calculating average Parcel Area?  I used to export to LandXML and do an area report in CSV.  That doesn't seem to be working for me when I export out of C3D 2012.

The workaround I found was to select all the parcels in Prospector, copy to clip board, paste in excel, find and replace "_Sq. Ft._" with 0, then do the average.

AutoCad :: Calculating Area Of Floorplan

Nov 1, 2012

Any good tips when it comes to calculating the area of a floor plan? You are supposed to start measuring from the outermost part of the walls, but when I do that I run into trouble with the porch on the bottom of the drawing and the room on top left.

The problems are basically that the porch is not supposed to be included in the total area, and in the room on the top I end up measuring a small area twice if I start my measuring from the outermost part of the walls. This is not very well explained but I've drawn two red lines on the drawing to try to show where the problem areas are.

AutoCad :: Calculating Area With 2010?

Jul 15, 2012

When I am trying to calculate area, i got wrong answer. At very first i thought it calculates area with inches (iam in metric sys), but then i checked options and its answer should be in mm, but I am getting wrong answer. In my object (which is rectangular) there's many other things, like hatch, buildings and so on. Maybe this can abstract for direct answer, because when i draw just a simple square or rectangle.

AutoCad :: Calculating Total Area Of Windows

Oct 31, 2012

I have a building like this and it has a lot of windows.

I know how to calculate an individual window area by using 'area' or 'ls' command. But this is just partial drawing and the whole building has hundreds of windows and it will take forever to calculate one by one and add them together to get the total area. Is there any way to get the whole area easily?

windows are just rectangles (and solid hatch inside the rectangle).

AutoCAD Civil 3D :: Shoulder Subassembly That Varies Slope In Relation To Lane Superelevation Slope

Jan 22, 2013

i need a shoulder subassembly that varies slope in relation to the lane superelevation slope. i know that i can get a subassembly for the shoulder that will follow the alignment superelevation xml data but in my case i can't use it because we are just adding a shoulder to an existing road. we're not changing the superelevation of the existing road, just milling and overlaying and widening. right now i've created a profile of the outside edge of the shoulder that gives me the correct shoulder slope but whenever i change my centerline profile i have to redo the shoulder profiles which is a real time suck.

AutoCAD Civil 3D :: Slope To Depth Of 10 Feet Than Change To 2:1 Slope

Aug 13, 2012

I am in the process of transitioning from land desktop to Civil 3D. I design roads in steep terrain and sometimes need to have my catch (daylight) slopes change. So my question is, how do I change a daylight slope at a specified depth? For example, from the shoulder of the road I want a 3:1 fill slope to a depth of 10 feet than change to a 2:1 slope until it catches the existing surface. Can this be built into a subassembly such that if the fill is less than 10 feet it will daylight correctly at a 3:1 and if the depth is greater than 10 feet then it carries the 3:1 for 10 vertical feet and then changes to the 2:1 until it daylights?

We have a good size channel and the section for the channel varies quite a bit.  We want to find the volume excavated in the channel between 2 elevations (it is the area of sand per the goetech report)?  A template was not used to create the channel surface, breaklines and gradings were used.

AutoCAD Civil 3D :: Calculating Volume From Corridor Models?

Sep 19, 2013

I've been learning civil3d for some time now and I really want to understand how the program calculates volumes from road corridors.

When the top code is used to create surface from a road corridor, the created surface coincides with the top of the road pavement (binder/wearing course), which is not part of earthworks.

How can I create a surface at the formation level so as to compute actual earthworks?

AutoCAD Civil 3D :: Calculating Volumes With Out Of Date Surfaces

May 9, 2013

I have been provided a file with a surface, however I have not been provided with the point files referenced to define the surface.  As a result, when I try to calculate the quantities in the volume dashboard using a volume surface, I get the error that the surface is out of date.  Is there a way to calculate volumes with an out of date surface?

I am trying to calculate the amount of material required to be cut when creating a flat bottom ditch.

AutoCAD Civil 3D :: Calculating Capacity Of Rectangular Pipe (not A Culvert)

May 7, 2013

In Land Desktop using the Hydrology tools, we could get capacities for rectangular pipes based on slope, size, etc.  

I have tried using the Hydraflow Express tools for this, but cannot figure out how to use them for a RECTANGULAR pipe (i.e. 10x4) box.  Saw the circular option, but couldn't change where it says circular.

This is not a culvert analysis because we have inlets, multiple slopes, etc.  It is part of an entire system.  

I use these tools to layout the system before I want to put it into the analyses software we are using.

AutoCAD Civil 3D :: Using Negative Cut Slope

Oct 30, 2012

I have a simple driveway corridor along a steep hillside.  For cut, I would like to have a negative slope away from the shoulder edge.  I have tried numerous approaches and all 'cut' reverts to positive.  I searched and found no clear answer.  It's such a short driveway, I can 'fake' it in, but I would like to calculate quantities.

AutoCAD Civil 3D :: Can't Display More Than Two Slope Ranges

I've got a surface that displays contours correctly. When I go to Surface Properties-Analysis tab, I can  set an arbitrary number of ranges for contours, directions, elevations, slope arrows, etc, and they display correctly.

I can set an arbitrary number of ranges in the slope range box too, but when I click the Analyze button, Civil 3D 2014 hotfix 1 only displays two slope ranges: 0% to 2979736.0077% and 2979736.0077% to 99999900.0001%. (!)
