AutoCad :: How To Find The Areas To Exact Precision
Sep 17, 2012
I have a problem of weather of not you can change the accuracy of the calculation of areas in AutoCAD 2011.
In my line of work, we need to find the areas to exact precision, though it seems that my AutoCad is messing with the calculations and rounding up.
E.G AREA - .017666 and turns it into .002
I calculate the Area thorught the usage of Polylines, and or the area command when i need to.
mabye to change it to give me EXATE AREA!?
those who are deemed awesome get a virtual cake, and the cake is NOT a lie....

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.

How can I find all pixels in an image with an exact, specific color? So far, I've only managed to find the pixels matching a pixel I click on; but I wish to find pixels matching a specific color value!

Is there a way to find the exact area of an irregularly shaped object? If there is, does the procedure work for compound paths (objects with holes in them)?

What is the difference between rooms and areas? Why create an area schedule off 'areas' as opposed to using 'room' areas? Can you create a schedule off room areas?

In the image below I have an aerial photo of an Island. I need to make it so as water areas are black and land areas are white (not greyscale) almost like a silhouette. My first plan was to draw round the island with a black paint brush and then use the "bucket fill" with a suitable threshold to fill all of the areas up to the black outline with black, however this doesn't work as the bucket fill either breaks through the black line or when I reduce the threshold, doesn't color the water areas solidly.

Colours are being over saturated in shaded areas and less saturated in light areas when filled over an aeea. The colours need to remain the same saturation level when darkened or lightened. Is a setting affecting the saturation levels?

I am working in AutoCivil 3D 2014. I have created a curve table for a plat of an allotment with the precision for the curve length set to "Normal Rounding". My problem is that we have to show data for the individual lot frontage as well as the total length of the right-of-way curve length. So the individual lot frontages must add up to the total right-of-way length.
If they don't, I have to make an adjustment to one of the lengths. If I change the precision of the tag syle, there is no change in the table. I have attached a screen shot to show my results. The left picture shows a "span" style with the tag and curve length with the precision "truncated". On the right, is what is in the table. I would like to keep the table dynamic and not have to explode it. I think my problem lies in the table and the only way this can work is if I can override the one length in the table. But I have not been able to do that yet.

I am currently using AUTOCAD 2012 free version for educational purposes. I have a drawing that requires high precision. It has a length of 1 cm and it goes as low as 0.115 millimeters. I would like to convert this drawing to direct .pdf. However, when I do, the dimensions get incredibly distorted and the lines get thicker. I have no problems in drawing the whole thing, but exporting to .pdf and even to .DWF is problematic.

Unable to change line label precision (both bearing and distance).
The goal is N10d10'10"E, 100.00'
Civil 3D 2012 is giving N10d10'10.00", 100.000'
I am using a template with the distance precision set to 2.
The drawing setting->Ambient settings distance precision are set to 2.
The feature settings distance precison is set to 2.

I have the following problem:
I have created a form in which I need to see the volume value. For that I created a User Parameter that is set to be equal with part's volume:
Volume=iProperties.Volume
What I don't like is that the precision for the parameter is too long and I can't change it. I changed the precision in Document Settings and also for the parameter itself in the Parameters window, but these changed don't affect what is the form.

How to set display of precision in my parts list to just one digit?
When I edit parts list set up im styles editor or edit parts list and go format column, apply units formatiing and set columns for one unit type and precision, then I get an error about units being incompatible because some items I have listed as each some by lf.
How to change precision in one column of parts list and keep unchanged unit formatting?

I made a drawing which contains lots of circles with a diameter of 12 and some lines that connect them. Pretty simple.
But.. i made the drawing with a x.xx precision (2 numbers and the program that has to load the .dxf file only likes all objects on the x. precision.. so no tents or hundredths precision.
I changed the precision from "0.00" to "0" in the unit settings but... the objects in my drawing still hanging on the old coordinates.
Is there any simple function or way to bulk action all this objects to the correct precision grid? I worked out that it is possible to select the circles which are in 1 horizontal line with each other and then change the Y setting to (for example) 45.0 if it was at 45 In this way it will put the circles on the correct grid. But... i have 1400 circles and lines
I also saw that the X coordinates of the circles in a horizontal line are different (ofcourse) and will be mentioned in autocad with *VARIES* I thought maybe can do something like *VARIES*.0 to put them on the correct grid but this kind of things didn't work.

How can I make better the second labeling precision in Civil 3D? It's only has four digits precision for the seconds. I did change the ambient settings (Lat Long precision to 8) but haven't got the result.

I've recently been playing with the "Retrieve Dimension" feature in IDWs to pull the model dimensions and tolerances from the IPT. I'm wondering if I am understanding the behavior correctly.
The IPT Document Settings > Default Tolerance "Use" and "Export" standard tolerance values boxes are checked.
I have standard tolerances defined for .xx and .xxx precisions. Default in the IPT is .xxx.
If I place a sketch dimension and extrude a feature, place that part in an IDW, and "Retrieve Dimension," the result is that the dimension's precision and tolerance are defined by the active IDW style.
However, if I place the sketch dimension, and then modify its precision to be something other than the IPT default, when I "Retrieve Dimension" in the IDW, it pulls the modified precision and tolerance from the IPT settings.
Is this the expected behavior? When I see the box in the IPT Default Tolerance tab that says "Export Standard Tolerance Values," I understand that to mean that the standard tolerance values in the IPT will be propagated to the IDW. Is this incorrect?
I'm using Inventor Pro 2013

Is it possible to change the precision in the properties box for the maximum and minimum grades and elevations of a feature line? I like to select my feature lines and see the minimum and maximum grades and elevations in the properties. (I keep the properties window docked and open at all times.)

I am working on updating my Parts List and ran into a little issue. When I make a Parts List with components from the content center, in this case some angle, I cannot get the correct precision.
See attachment.
The first picture shows the correct units in the QTY column but I would like the 2.000ft to just be 2ft. If I modify the style to correct the precision it adds the units to every item in the QTY column as you can see in the second picture.
Is there a way around this without editing the Parts List each time I create one?

All the values I put in to set my tolerance are being rounded to three decimal places even though the value is four place and I am setting the dimension precision to four place.
For Example: I have a hole of diameter 2.0466. It is to have a tolerance of +.0005/-.0000. When tolerance.setToDeviation is called, the .0005 is strangely forced to .001 and is set as this in the part file. The precision value had already been set to 4 at this point.
I am using the following code in Inventor 2010:
'Create hole feature
Call oCompDef.Features.HoleFeatures.AddDrilledByThroughAllExtent(oLinearPlacementDef, dDiameter, kExtentDirection)
'Get hole feature just created
Dim oHole As HoleFeature
Set oHole = oCompDef.Features.HoleFeatures.Item(oCompDef.Features.HoleFeatures.Count) ' need most recent index
[code]...

My parcel inverse reports from the Toolbox Report Manager are still coming in with the bearings having decimal seconds to 3 places (N 0-00-00.000 E). I have already changed the variable for angle precision to zero in the "General_Formating_JScript" xsl file but it's still not coming out correctly. Is there any other file that holds an additional angle or bearing precision setting?

When referring to flat pattern length and width you can make an custom iproperty and add =<Sheet Metal Width>. You can then add 2 fields in the drawing parts list and set precision, trailing zeroes and unit string on/off.
Most companies have 1 field for 'Size' or put size inside description and then you cannot format
The problem is that if you fill in description: =Sheet <Thickness>mm, <Sheet Metal Width>x<Sheet Metal Length> you get the following:
Description: Sheet 15mm, 3411,978 mm x 2000,000 mm
i Want to have Description: Sheet 15mm, 3412x2000
You can't change property format as you can with user parameters you set to export as far as I know. Is there a way? excluding iLogic, which would only be a half baked solution. I would really like to have width and length as a sheet metal parameter, rather than a iproperties formula.

I have had a problem with retrieved dimensions decimal precision. I set the precision to 1 decimal place in the ipt but when I retrive the dimension it set the precision to 3 decimal places. I then go to the precision control in the drawing and change it to 1 decimal place.
If I then go back to the ipt and edit the dim, the drawing precision then jumps back to 3 decimal places. (This is particular to the decimal precision for the tolerance of a dimension). How to sort this out?
