i have a number appear when a get the AREA of the attached rectangles shapes especially when i use SMD ucs.for instance see the rectangle C07 74 X 39=2886.00000000 BUT i get the area like 2886.000000003.why the precisions doesn't all 0...

with this I changed placement of coordinates from being outside of a viewport to inside.
However, I still do like this unnecessary zeros in the end of numbers.
Do you know how to get rid of them in a code?
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.
View 5 Replies View RelatedI was just wondering why there is no base unit for parts based on Area?
I model a lot of parts that are made from Plate.
When you order or sell plate it is usually sold by the Square Meter
The same would go for Square millimeter, Square foot etc.
Also other base units would be handy like Pack, Box, Carton I am sure there are many more.
The main one I really can't do without is Square Meter.
In Civil 3D 2013, when I execute the _area command, i get results in square feet as opposed to acres. Under the ambient settings, the area unit is set to acre. how to get C3D to display my area in acres? I just want it to list the area, not label it.
Also, is there a way to get it to display the area in BOTH acres and square feet?
I've recently migrated from AutoCAD 2008 (non-industry specific) to AutoCAD 2010 so I don't know if this was an issue in 2009.
Back in 2008, when I choose the 'window' option when specifying a plot area, AutoCAD would show the workspace so that I could manually select a windowed plot area, and at the same time the whole workspace would be greyed out except the previously active window area.
This was handy, because we can have as many two dozen title-blocks (and therefore separate viewports) in paperspace, and knowing what plot area I last plotted or added as a saved page setup.
In 2010, it no longer does that. I now have to rely on the dashed border to know where the active plot area is/was (checked 'display printable area' in options>display tab) which I personally don't really like using.
I had tried to draw in different units in autcad other than inches, but fail to find i way. I tried going on tutorials, but all they say was to type in:
"Type in Unit in command
Press enter
A option will pop up
Change Units to whichever.
Okay so I tried this, and I change it to feets. The problem is, that whenever i draw a line, it would always be in inches. I want to find a way to draw in feets, so how I can do this.
So we have started some work overseas and I have been trying to make sense of the metric units in CAD. Metric units in general, make way more sense then imperial units but how they work in CAD has been confusing.
I am familiar with the UNITS command and have changed the drawing units to "decimal" and the insertion units to "unitless"
I know that when you draw a 1 unit line in model space it could represent a 1 millimeter line or a 1 meter line and that it is up to the drafter to decide what it will be. I also am familiar with setting up dim styles to dimension correctly based off of whether you are drawing in meters or millimeters.
I have set my Adobe pdf printer to A1 23.4" X 33.1" (594mm x 841mm). when I draw a 1 unit line in paper space and print the layout the 1 unit line measures 1 inch?
I have a query on the units for Autocad, every time i start Autocad up it defaults to inches, i have to change the units manually to mm using in units. is there a way to set this that i don't have to keep doing this?

View 3 Replies View RelatedI sometimes am given drawings which are done in a software package called LSS of which I do not know much, these drawings are usually to show a model of a band, by using contours of a site on which I am working and are saved by LSS in a dxf format so I can then import them into my autocad drawing.
The problem I have is that I also have drawings of the same site from a surveyor which has the buildings new and existing, but they are in different units.
The surveyors drawing for instance the grid measures 100000mm whereas the LSS model drawings the grid is 100m.
This means the coordinates are different so it is difficult to match them up , the only way is I have found is to rescale the LSS drawing up by 1000, then find a common intersection i.e. corner of boundary line. This is not always very accurate.
The guys who do the LSS drawings tell me they cannot change the units to mm.
a) can send me geological elements hatching patterns in .PAT format to g.jamalashvili@gmail.com (e.g. hatch for tuffs, basalt, tuff breccia, andesite, dacite, diabase, etc), or
b) Websites where I can dowload them or otherwise buy them quickly...
I'm using the exporttoautocad command to convert a 3D drawing with a proposed surface (a TIN object) into a drawing with just contours (polylines with elevations). My original drawing is in feet and has a NAD83 state plane coordinate system.
Everything seems great in the exported dwg, except it is converting the elevation units from feet to inches!? A contour that was originally at an elevation of 7.0 feet, ends up at 7 inches in the exported drawing. Spatial coordinates are preserved.
We have some machines which seem to work in imperial maesurement a dn others which work in metric. it is frustrating when trying to insert a map block that is metric and is inserting into a drawing which is set up as imperial. We have tried using the - dwgunits to change to mm, and then using insunits , insunitsdef source and insunitsdeftarget to 0, this works when the PC is currentyl in use. when shut down and restarted it reverts back to imperial setting.
Am i right in thinking this is something that needs to be done at the software installation stage to make it default to metric everytime?
I have a venue drawing that is in mm and I need to convert it to ft/inch so I can update and get dimensions from it. Can this be done so when I change the format in drawing units it will update the drawing units?
Current settings.
Drawing units
Length:
Type - Decimal
Percisin - 0
Angle:
Type - Decimal Degrees
Precision - 0
Insertion Scale:
Unitless
I want to chose the better, to start drawing. I use inches at work, but I want to use international system for myself for personal projects
I think there is a standard unit in files imported o r exported from another soft, smaller files, easier size to process by pc, quicker units to introduce, accurate, prototyping models soft compatibility, etc.
Any previous criteria for recommendation is perfect.
¿Which is the best measure units to use?
Spoiler (Highlight to read)
I am displaying dual units in a drawing with primary units being Customary. The metric unit displayed is incorrect.

View 1 Replies View RelatedWhen 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.
View 9 Replies View RelatedI 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.
Is there a command where I can stretch an object and keep its Area. Like a baseball when hit turns into an oval however keeps its same mass.
Not like the Stretch command that infinitely stretchs an object.
Suddenly I got this issue when I draw an area boundary its not possible to close it with "enter" or "spacebar"..

Its terrifying how many official documents may be wrong because of this bug.
I would like to be able to draw squares by the area they should have. So that if I need a square of 50m2 autocad automatically draws a square of sqrt(50) x sqrt(50) Because right now I have to draw 200 squares with 100 different areas and I have to calculate and manually draw each one of them.
View 3 Replies View RelatedRecently, on my machine i have noticed that the print area (layout white space) of my drawing in paperspace moves and re-sizes every time i print.
I am trying to create a template and want everyone to print "layout" as a standard practice. But, if i happen to change to print window and window something off the page the layout space (white area) has now been resized and moved to the area i just windowed.
I want to print something "off the page" this time is no reason to change or modify the LAYOUT area that was initially specified. This never happened before and is not happening to my colleagues, so this must be a local setting.
I have a 3D polyline (blue in attached) for which I am trying to calculate the surface area. I use the area-->object command and get 1912342m2 in AutoCAD 2012. My colleague uses the same command in AutoCAD LT 2009 and gets 1807093m2. Due to the discrepancy, I roughly traced a polyline (yellow in attached) around the area in AutoCAD 2012 and I get approx. 1810000m2 so assumedly the AutoCAD LT 2009 version is giving the correct answer while my AutoCAD 2012 is not!
Why am I getting a different area for the polylines...is the difference is due to it being a 3D polyline? Is there a way I can ensure I obtain the correct area using the 3D polyline?
I have an 11 x 17 border (true). I am printing on an 11 x 17 sheet (true). I have specified 11 x 17 sheet in plot dialogue box.
SO WHY IS MY PRINTABLE AREA 11.5 X 17.5??
i have established LIMITS at the corners of my border. there is nothing else outside the border.
this is for a template. i would like to establish the 11 x17 LAYOUT and lock it in position, never to be changed again. If someone wants to print a portion or outside they can use WINDOW, or EXTENTS, but, when LAYOUT is selected i want to see an 11 x17 rectangle eliminating from the 0,0 point and nothing else.
Plotting to layout (as opposed to extents or window) is infuriating. I cannot get my drawing to center properly within the printable area, and I can find no consistency on how AutoCAD is offsetting my drawing. My titleblock is drawn with a trim line of 22x34". I choose the ANSI D sheet size which is 22x34" and when I preview the plot the bottom left corner is offset from the bottom left corner of the printable area by .25, .25.
If I delete the 22x34 trim line from my titbleblock and replace it with a simple point at the 0, 0 bottom left corner, then when I check the layout and printable area, the point shows up offset from the bottom left corner of the printable area by .0006, .0016. Why is it any different than when a line was drawn? If I delete the point the offset from the bottom left corner of the printable area to the closest drawn element then becomes .0013, .0012.
This is absolutely ridiculous. I want to batch plot and I want to have proper margins, but it seems nothing renders consistently and I am stuck with ill-formatted plots. I would love to batch plot to extents, but as I go through the setup, that is not an option for me, so I appear to be stuck with the layout, which I have never gotten to work properly since it was introduced. What is the trick to make it work?
I am just printing to Adobe PDF with the Acrobat printer.
I've just got AutoCAD 2012 and mkaing some rings, I needed to fit the same textures of a ring of 8mm in a 6mm ring. My problem is that the inside diameter is larger in the 6mm ring, and that's why I can't use the Scale command. Is there a command that allows me to fit all the objects in this area??
Here is the file with both of the rings.
while tracing a plan on Autocad 2010, by accident I clicked on something, or performed some unknown commands. My lines, that were smooth just seconds before, suddenly became really pixelated, as if made of many small segments. And when rendering the plan on pdf, it is still the same, and the lines are really thick. I have checked, the line thickness is on default (0.25mm), but compared to renderings I've done before, this time the drawing has really awful lines.
