AutoCAD Map 3D :: How To Measure Area (sq Meters) In WGS84
Sep 19, 2012
We are able to measure distance in meters between 2 points using COGO tools. Though, when meassuring areas (command area) even setting units to meters it shows: "Area = 0.00000073, Perimeter = 0.00343123" which is not expressed in meters. The area in meters is around 8900m2. We are using latitude, longitude LL84 (WGS84). Is there a way to easily measure area over the map using this coordinate system?
The attached lsp puts tick marks at equal distances along a line/polyline and tags them with the distanace value from the start point. I draw using millimeter units but things like chainage should be displayed in meter units. Using this routine displays the values in millimeter units which I then 'find and replace' to edit their values to meters.
Take a look at the lisp to see if it can be altered to input the mm value at the start but output the meter value to the text values?
Found that in certain drawings, the measure area tool will just suddenly stop working? It's very odd. It let's me pick points, but won't let me press enter to see the total.
Closing and reopening AutoCAD doesn't work. It seems to be a permanent thing to the affected drawing.
It's happened to me in a few drawings, but only in those specific ones. Other drawings are fine. I'm guessing it's a setting I've changed somehow?
I've been getting round it by creating shapes using the polyline, and then looking at the area in the properties window. It's an ok solution, but not ideal.
Is there an 'easy' way to see a cross sectional area and measure it? I have tried getting a cross-sectional area by off-setting a work plane into the model, sketching on that plane, and pressing F7.
This shows the cross-sectional area, but when I click the inspect>area I can not select the cross-section. Any thoughts besides creating a sketch on that surface and extruding it to remove; taking the area measurement, and then undoing the extrusion?
I'm wondering if there is a lisp possible to measure area's by pick point (as in bpoly). This little feature exists in Microstation so i was looking for something similar.
Is it also possible if this lisp can measure areas from an external reference (dwg, dxf, dgn, shp etc..)? I'm kind of new to AutoCAD in that sence.
How to create a revolve surface in an assembly for the purpose of measuring a flow area through a specific area? See the attached JPG, I basically have a conical internal diameter with a pin protruding into it..... I need to measure the flow area as shown in the sketch attached here. the way I have this shown in the attached JPG is the way that we had previously performed this in Pro-e.
I have cs3 extended. Is there a tool ( i can't find one) that will allow you to make a selection and then calculate the pixel area of the selection? For measuring areas in a scientific application.
I need to be able to measure the square inches of a printed area in which hew will be using specialty inks. We want to get a descent cost estimate, how to measure the square inches of a specific element of a design, in Photoshop or any of the other adobe programs?
I have a utm .tif and .tfw files which I need to convert into a wgs84 ascii file (csv ideally) with the full list of x,y and z values. The UTM needs to become geocodes and it needs to be in ascii. I am using Civil 3D 2012.
I don't know what to do with my drawing Units and Scale.
I want to draw in Meters! But when i make a rectangle 30x15m it looks so small that i can't see it in my draw. Using my scale is 1:1 and Units Meters.
I tried changing my scale and my units and the rectangle still looks the same way it was. If i want something to look big, i have to draw in mm, for example, 30000x15000mm rectangle.
But, when i do that, everything go wrong...For example, when i draw a rectangle in mm (30000x15000) and i change the line style in layer command or when i try to hatch/linear dimension and etc all looks very small or very big.
I still cant understand about the units. I open acad iso template to work in mm and the insertion scale is also showing in mm.what if i want to draw in meters or cm.
I recieved a drawing in which the coordinate values are a thousand times too high; they are in millimeters and I need them in meters. I checked the settings of the drawing, and it clearly says that it´s in millimeters, but it doesn't change the setting or to copy the whole drawing into a new file with meter settings.
i want to draw a line long 3 meters and i have to type @ before typing 3. If i dont type @ then there is a problem when i want to dimensioned it - there doesn't appear 3 metres but totaly different number. why that happens?
I have some annotation scale in my drawing but over the course of the last year many have come from different places.
We use Annotation scales called Meters 1:1000 but another company we work with use 1:1000m. Is there a way to merge these two annotation scale to Meters1:1000?
Is there a way to change the annotations so that they become millimeters and not meters?
I dont really want to change my entire drawing to millimeters because i have other drawings in my model space which suit meters. It's just this one section I have drawn is so detailed and zoomed in, it really should be in millimeters.
If there isn't i'll just change the whole drawing, but thought I should ask on here first in case I was missing something obvious
I am trying to set up a METRIC project (that I want to make template) that uses meters instead of millimeters.
So I created a new project, without the use of any template. I copied from the default Autocad templates folder the Model and Sheet templates to the new project folder and I set the units, scale and grid to meters and changed the path in project properties to these files.
Everything seems to work fine, except creations of sections/elevations.
I edited the SectionStyles (Metric).dwg file in default styles folder and It works fine.
But I donțt want to change that file in the default folder, but to change the path of the section styles in the project. The only way I could do that was to change it in the tool palette - right click on callout.
So how can I make the SectionStyles to load from a specific location for a project without having to right click on every callout that I want to use and change it manually?
There are some other things to do/change for making the project template that I want? (I am referring to the units setup).
I have a set of dimensions in meters and I am trying to automatically convert to feet. So I am going to the Dimension Style that rules the numbers that I want to convert and after clicking in Modify button>Primary Units I go to Linear dimensions group and change the Unit format from decimal to Architectural and 100 m turns to 8' - 4" not to 328.08'.
I have been sent a DWG floor plan from a firm in South America. The existing file is Type: Decimal and Units to scale: Meters. We need to convert the file to a useable architectural and feet set up. I know that I will need to scale the existing dwg however I am not sure what the exact steps are or what I should scale it by. Should I change the drawing units first and then scale? Or the other way around? Biggest thing I need is the scale factor.
I'm trying to create a surface from a DEM (as a *.adf file)
How to convert between coordinate systems. (a UTM system to a State Plane)
How do I control the elevation values? My DEM has x,y coordinates in meters, but elevation values are in feet...
So far what's happening is that I end up with all the z values multiplied by 3.08... (I assume it is trying to convert the meters to feet..., but since I already have feet in the DEM ... no good)
