AutoCad :: How To Find Areas Of Stream Cross Section
Mar 13, 2012
I am using autocad to find areas of a stream cross section such that when we take a water height measurement of the stream in the field, we can easily get the area from a spreadsheet since the cross section of the stream at any height will be known (once I get done in AutoCAD).
To further illustrate my needs, I have attached a picture. I need all the seperate areas between the red lines (the red lines are equally spaced vertically and have lengths that go end to end to the edges of the stream).
I have been hatching between the red lines and taking the areas of each hatched object. However, this is a slow and tedious process.
Hatching is not the issue because I can hatch multiple objects at once using the create seperate hatch option.
What I need is a way to list all the hatched object's areas into a text file so that I can easily copy and paste them into an excel file. Even if it is not a nice and neat list, I can atleast use a find for "area" to get them into a nice list a little faster.
I received a cross section file that was created in Micro Station and need to calculate the cut and fill of the project. There is no way to get the 3D files the cross sections were created from. Everything in the file is exploded and flat.
I was going to hatch under and above the existing grade to find the cut and fill and then thought about the scale of the cross sections. In model space the cross sections are 1=1 H and 1=10 V. When I do a hatch and get the area it is giving it to me way high. If I just divide by 10 I don't think that is right either since the hatch areas are very irregular.
Scale the cross section vertical down by 10 and don't change it horizontally. I don't know if this is possible.
Somehow set the horizontal and vertical scale and hatch above and under to get the areas. I don't know if this is possible either.
How to find the cross section details like area and movement of inertia at particular cross section
in( solid works there is a direct option select the section and select the face and click on the calculate automatically gives the are and movement of inertia etc in part and sassy level also) but in inventor in part level its possible but in an assembly level.
I am trying to annotate a floor plan to show the location/orientation of section, elevation and detail drawings. The labels must also indicate the appropriate drawing cross reference. (basically a circle with a arrow, text inside circle showing drawing cross reference). My question is - is there an automated way/library to insert such labels or do I have to create each of them from individual elements and make a block?
I am trying to verify the bending strength of a solid part. Need to calculate the section modulus on certain cross section. Don't know how to do it using inventor.
My solid model is imported from IGES file format. I'd like to make a plane at specified location (perpendicular from the surface), and I'd like to have a cross sectional geometry cut by that plane. (attached pic.)
1. How can I make a plane following perpendicular line from the surface? 2. How can I export the cross sectional geometry?
subassembly from centerline is LINKOFFSETONSURFACE out to a target alignment
next sub is good old LANEINSIDESUPER, using depths for PAVE1DEPTH and SUB-BASEDEPTH
the corridor definition under SURFACES specifies top links for both PAVE1 and SUB-BASE surfaces, but they appear to ignore that and cut across the road (see graphic) making a mess of it
do I need to add a link code to LINKOFFSETONSURFACE subassembly? other work-around?
if i have one feature line i want to project to all sections in a sample line group it would seem you should be able to pick the one line and assign in a label style and you would be done quick and easy. instead if you pick the multiple projection option you get this percentage distance box and it tend to grab stuff you don't want.
I'm just starting to get involved with using SSA, and I'm wondering if it's possible to import sample lines/alignments (a la Hec-Ras). I see that there's an irregular channel editor, but no import options that I can see. I'll end up with about a dozen or so x-sections.
I have a band label set up for my cross sections that will show existing grade and finish grade elevations at the 0' offset mark of each section.
However, the band does not show when I create my sections. The only way I can seem to get it to show is by right clicking a section, section view properties, bands tab, click 'import band set' at bottom of window, and select they style i want to use. But I have to do this for each section individually. That is a problem as I have over 200 sections for one piece of this project.
I'm currently working on a cross section plan and was wondering if there was any way I can change the direction of the cross section view. I'm currently just using 2 sample lines, so just 2 views are needed. My problem is that it seems like one cross section...the view is facing upstream and the other sample line, the cross section view is facing downstream.
Is this normal? How come both cross sections don't face the same direction? So with one x section it's in a East-West direction but the other is a West to East direction.

I am working with cross sections for the first time and have run into a few things I can't seem to figure out. In attachment XSEC CIVIL 3D.pdf you will see how the cross sections currently look in my drawing.
My questions:
1. I cant seem to edit the elevation labels on the right side of the section to match the left side. Where/how can I do this? 2. What is the red line? In some sections it exactly follows the assembly section, but in a few (like this one) it doesn't quite follow. Does this line show where manual editing was done? 3. Where the pavement ends, there is a vertical line which I only want to show on the two pavement layers, it shows all the way thru the assembly. This also happens at the centerline of the assembly and at the edge of shoulder. I figured out how to turn them all off, but I want the edge of pavement vertical lines there. 4. Although the assembly section comes in on color 161 which should plot black for my pen setting, it plots true color. I haven't been able to figure out how to switch this. The second attachment shows a section from a LDD project a few years back which is how I would like this section to plot.
I am a new user of AutoDesk inventor and have a few questions about saving different views of the drawing. I have a floor plan layout and need to save several different cross section views to see different angles and different parts of the interior. I am familiar with how to do this in programs such as google sketchup but not inventor. I also need to insert text with arrows pointing to different things in the drawing. Is this possible with inventor or does the drawing need to be put into other software such as paint.
create a label style for cross sections that will label the travel way in the run:rise format and will label fore and back slopes in a percent format. I can figure out how to make them all one or the other, but am having trouble getting them to reflect correctly based on where they are attached.I am having trouble coming up with the actual expression or you can do it thru code set styles, but regardless of settings that I change nothing on the cross section view changes.
I've created a solid in Inventor and used the Section Analysis tool to create several cross sections. I'm trying to find a way to export the geometry of each cross section to a some format so that I could laser cut each cross section.
I have been asked to place volumes on cross sections with a certain look, that I am not sure if it is possible. For know I am just going to use text, but I would like to come up with a solution for our template and work flow. Below is an attached copy of a markup I have received asking me to show this information on the cross section similar to how he has written it. At this point I only know how to create the tables of to the side. Is it possible to dynamically show this information quickly like shown below? I have a feeling the engineers I work with will not be happy at all with a table off to the side. I am currently using 2013

Using 2011 - Having trouble with cross section labeling. I have multiple label markers such as ROW, and multiple EASEMENT types. I've created corridors for each label type - each will show up if their corridor has a corridor section line at the same station as the base corridor, but at odd ball stations (like driveway openings) the labels do not show up, I'm thinking its because I don't have these corridor section lines in each corridor. Is there an easier work around rather than manually adding the section lines in each corridor?
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 a series of points from a cross section taken using an adcp and i am trying to draw the cross section in autoCAD lt 2014. is there a way i can enter the points as a sort of script so i dont have to manually typoe in the distance and height between each point as i have about 200 points in each cross section.
I am creating a data band for Finished Ground. I have created a Top surface from my corridor and have sampled that as well as my original ground. I am trying to add data bands to an existing cross section view. When adding data bands for the cross section, I first go to the Section View Properties, add the data band, in this case, "FG Elevations", In the "Section1" column, I pick the Corridor surface that was sampled.
The data band does not display data. I know the data band works, because I picked the original ground as the "Section1" and it gave me the elevation.
I have noticed that under the "Sections" tab of the Section View Properties, and in the "Type" column, the original ground surface has a different symbol than the corridor surface. I have also noticed that if I have only the "Draw" boxes for the sampled corridor surfaces in the section view checked, nothing is drawn the section view. The corridor surfaces seem like they are not really there. Am I not able to retrieve data band data from a corridor surface?? If this is the case how do I go about making the corridor top surface something I can get data from?
