AutoCAD LT :: Area Calculations In 2013?
Dec 17, 2012
I am trying to calculate the area of the attached file. Just the Blue section. Is there a faster way to calculate the area than using the "area" command, then going through and selecting each line, then each arc, over and over again? I also tried making a poliline that follows the entire pattern at the width I wanted, then using the "area" command for the "object" that is the poliline. This is faster, but does not give me the correct area. It says that the calculated area does not take into consideration the width of the poliline. The width of the poliline is very important in my application, and will sometimes be changed. Than a new area will be needed with the new width.

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.

Any routine or tool that simplifies calculating and labeling floor areas?
Currently, I draw a polyline around the desired area, list it to get the square footage and then create a text line and type in the square footage. This method takes multiple steps and is easy to mistype the area.
I would love a simple tool that would let you draw a polyline and automatically label it for you.

I am relatively new to AutoCAD LT and I am constructing floorplans and measuring the area in m2. My problem is that my areas are not adding up correctly. We are investigating possible future redesigning of units, and although the outer boundary of the building is the same, when I add up the individual units this total area does not add up correctly. While trying to figure out what was going on I traced one unit exactly on another layer and compared areas between the two identical polygons....and they have different areas!?!?!?

I must monthly calculate quantities. So i have 3 surfaces, one is representing the original ground level and the other two the measurements on the end of the months. Between the measurements I calculated volume. But I want calculate the quantities what is inside of the original ground level, what is outside that I want to exclude from the calculations. There is a way how to crop that surfaces to match with the original ground level?

I have been dealing with a tolerance issue when trying to create room area calculations in Revit. There seems to be a tolerance that is set to somewhere under 9" if two walls are to close together it will ignore the area.
Although if you are using the area calculation this tolerance is set much finer. and it seems to work just fine. I have already tried to create a multicategory schedule but cant combine rooms and areas. I have attached an image .

how to calculate the gross area of a portion of a building - it is about one-third of one floor of the entire building but is comprised of several rooms. I need this for both tenant area and for figuring the area of insulated floors for purposed of energy-code analysis.
Is there a way of just going about it the old AutoCAD way via a P-Line? I know there are no P-Lines in Revit, but is there an easy way of doing this?

how to get the area of this polyline .........
i used properties command >>>
i used li command >>>
i used area then o command >>>> it says that area = 362.5350 ok this is wrong ..
i calculate the area of the polyline by separating it to parts then subtract the area >>> 368.62 - 7.79 = 360.83 this is the correct area
actually this is to hard to separate polyline to parts, when i have alot of polyline.
i guess this problem causes, when you have self-intersecting polylines the file is attached ..

Let's assume we have a square drawn and another smaller square inside of the larger square. If i want to figure out the area of the larger square less the area of the smaller square but adding the perimeter of both squares, how do i do that? I know i can select the square and the properties tab will provide the area and i know i can use the area command and choose "subtract area" and do it that way. But my friend tells me theres a way by just selecting both objects that the properties tab will automatically do that for me. But when I select both objects, the properties tab under geometry would just say "varies" and not do the math for me.
I don't know if this provides additional information but he says somehow both objects are linked, like a block where its really one object and not 2, but when you explode it, it becomes 2 objects and therefore will now say "varies" on the properties tab as opposed to doing the math.

Presently the "AREA" of a closed polyline is in "sq-in" first, THEN "sq ft".
For everything I do, and likely others, I need sq ft - without having to waste time and roll my cursor over the results.
Is there ANY way to change this default to have sq ft FIRST!??

I used to be able to obtain the sqare footage of an area with the AREA command. A list would generate about seven or eight lines, listing the square footage, inches, perimeter etc.
Now all i see is one line; the area/perimeter (see attachment). Did i change a setting somewhere to obtain this simplify version of the AREA cmd? Something is not right...
I tried the MASSPROP and MEASURE GEOM, those will not show the square footage. This used to be so easy, what am i missing...

Have recently upgraded to 2014 and can no longer get the AREA of a closed polyline in quick properties. It is no longer an option when customising the quick properties information. I know you can measure area in a number of ways but it was very handy to click on a closed polyline and have the area of that object come up in the Quick Properties window.
how to get the Area of a closed polyline in Quick Properties for 2014?

When I was using AutoCad 2010 I could HATCH within a cube, circle or within any object that was joined together even if it had text in it would HATCH within the boundaries of the area to be hatched. Now that I use AutoCad 2013 this option does not work as if there is text in the object only a partial area will become hatched. This means I have to MOVE the cube or whatever shape to a place where there is no text inside it, HATCH and then move it back to where I wanted it in the first place.

I'm looking at several surveys and using plines to quickly map it out and divide. But then to find the area in acres, I'm using a seperate calculator to convert the area given in the properties box.
I've searched and found that there was lisp used before acad 2011. and was hoping that there maybe a way for acad to do it now.
Can I just change the units from sq ft to acres in that field on the properties box in acad 2013?

I've read through some of the discussions on this subject. I have three lines of command visible. I blocked out my file. I audited my file. I have Service Pack 1.1 installed. I still continue to have intermittent problems with the area command. Please see in the attached video how it works in one area of my file, but not another area of the same file. URL....

I have my original surface I created with my point file and break lines. I created a new surface and was able to determine how to create my grading at a 3:1 slope that stopped at the surface I created from the point files. From there I went back to my Grading Groups and selected the Automatic Surface Creation.
From there I don’t know if I have to selected the Volume Base Surface and selected the surface I am grating from or if I can simply create a volume tin surface selecting the new surface and the original point surface for comparison. How do I make sure the Volume I am getting include the volume from the grading slope?

I have no background with AutoCAD 2013, but my boss has given me the software and tasked me with taking entire floor plans of an individual floor .dwg and create smaller areas of each floor into separate, new .dwg's (like several rooms together) that then could be converted into .pdf's for sharing and/or printing. I have tried to find a simple tutorial or explaination of how to do this, but AutoCAD is such an amazing and complex tool that I'm having trouble with the terminology even.
I was right-clicking on the 'Model' tab to create a 'New Layout', right-clicking that to get to 'Page Set-Up Manager' and 'Modifying that to select 11 x 17, Landscape, and 'Adobe PDF' in the Printer dialog box. When I worked in the new Layout window sometimes I could zoom in to a section of the floorplan and then go to 'A' button in the upper left corner and select 'Print' and sometimes the resulting .PDF file would be that smaller section, and sometimes it would still just be the whole floorplan.

I can't seem to confirm the discharge table that hydraflow produces in hydraflow hydragraphs. I think I understand the equation itself (it's been a while since I took hydraulics), but can't understand where I'm making my error (if I am). Normally I trust the stage/discharge curve that hydraflow produces, but the City Engineer is asking me to confirm the values by hand and show them on the plans. Is there a link to an detention pond example that shows how a curve (the outflow values) was generated (confirms the discharge table at various elevations)? The equation is on page 85 of the users manual.

I have been asked to do volume calculations using Civil 3D for some concrete piles for a oil/survey company. I have done volume calculations for site and land development projects but nothing to do with concrete piles before. It also appears I am the only person with any Civil 3D back ground in the office. I did mention my experience with Civil 3D was limited but I was trying to expand it by looking for Civil 3D jobs and working through the 2012 Mastering AutoCAD Civil 3D book.
I am assuming doing volume calculations for concrete piles is quite different from doing volume calculations for grading plans. The company has been primary using AutoCAD Maps and doesn't have much set up for AutoCAD Civil 3D yet.

I built a containment dike using the grading functions in Autocad Civil 3D. I set up the feature lines at the top toes of the embankment and graded nicely down to the original dtm. I want to use user defined contour to get the interior storage from the original dtm up to a selected elevation within the containment dike. The containment dike forms an enclosed area. I know I could use infill and add a false bottom to the embankment surface (triangulation from bottom toe of embankment across to opposite embankment) but I want to check storage from original ground dtm.
Is there a workaround method to do this without creating infill? I know I need to get down to two surfaces to get a calculation.

I am using the calculation tab in the bolted connection generator. Is the maximal tangent force (Ft) the total force of plates in shear or per fastener? It appears to be the total force because changing the number of bolts changes the results.
I have been running different configurations due to a failure in a test cell and the numbers don’t seem correct. The calculation indicates that the fastener would fail at a much lower force than it actually is.

After starting my previous thread "What formula will work to achieve this result" I decided to post this new thread because I have changed my mind and will now be using the external Excel file that the "Extract Data" creates to do my calculations.
Here's what I would like to do: create a Macro [button] in Excel with the following conditions:
*
Sample of excel spreadsheet:
*
MANUF NoSUB No.DESCRIPTION** UNIT QUANTITY
A123494456TYPE A, XXXX XXX * * * * EA** * * * 45
A423520374YA1AM, XXXXXXXXXX * **EA** * * * 55
A148231375TYPE B, XXXXXXXXX * * * EA** * * * 33
A146151725A1AAM, XXXXXXXXXX * * EA** * * * 67
A135621873TYPE A, XXXXXXXXX * * * EA** * * * 24
1. * * * CONDITION #1:
IF "DESCRIPTION" TAB ["C" COLUMN] CONTAINS "TYPE A" AS PART OF TEXT/DESCRIPTION, TAKE THE "QUANTITY" TAB ["E" COLUMN] SPECIFIED ON THAT PARTICULAR ROW AND DIVIDE IT BY 20, ROUNDED UP TO NEAREST ONE.*
2. * * * CONDITION #2:
IF "DESCRIPTION" ["C" COLUMN] CONTAINS "TYPE B" AS PART OF TEXT/DESCRIPTION, TAKE THE "QUANTITY" SPECIFIED ON THAT PARTICULAR ROW ["E" COLUMN] AND DIVIDE IT BY 10, ROUNDED UP TO NEAREST ONE.
3. * * * AUTOMATICALLY SAVE THE EXCEL FILE AFTER THIS MACRO HAS BEEN UTILIZED.

Any way for Vol. calcualtions to be shown in Acre Feet? I am doing Volums of lakes and the client needs a report of the number of Acre Feet in the lake. To get the data, he uses a depth finder hooked up to a GPS. I can do this by hand calculator but using Civil 3D 2013 would be much easier.

I'm wanting to know if there is a way to Copy a selected area from Excel and Paste into Autocad and have it as lines and text objects?
Before everyone is entering the information in RED multiple times, once in excel and again in our cad file.
I don't want a data link because we are sending, only, cad files to our customers.
