AutoCAD 2010 :: Measuring Area Using Override Dimensions?
Jun 13, 2012
I am responsible for populating a database in which one of the fields is the area of individual rooms in a building. The instructions indicated that I was to use polylines to enclose each room / area and to find the area based on these values.
Earlier this year, another student was hired to confirm the measurements on building blueprints. This student took accurate measurements of each room, however instead of correcting the drawings, he simply added override text to the dimensions. Therefore the displayed dimensions are correct but my area values using polylines are inaccurate.
The project that I'm working on includes a number of drawings and close to 1000 rooms. I downloaded a function I found online that allows me to figure out which dimensions were overridden by boxing them in a different colour and I've found that it is a significant ammount.
Is there a way to use these overridden dimensions, without altering the physical nature of the drawing, to find the area of a room?Need to use polylines to calculate area of many rooms. Dimensions have been overridden and are inaccurate. Can i use the overridden dimensions without altering the physical drawing?
I am trying to measure the area of an office space within the stadium and keep getting a ridiculous figure - it keeps saying that it is something like 14 thousand square metres. Am I doing something wrong because it should be coming in somehwere near 150 sq metres?
Two different problems (questions). These are IV2012 files but the problems are the same in 2013.
Open the two attached ipt's. Launch the Measure Distance tool and measure between the blue an red face on the DimTest. It should read 1 inch.
Change to DimTest Derive using the tabs on the status line. Measure still gives 1 in. Change precision to All Decimals. The mouse pointer changes to calipers and the distance now measure 1.004 (which is correct)
Switch back to DimTest again using the tabs.
Measure again and notice the mouse pointer still shows the calipers which imply that it is going to return all decimals but the dimension given is still just 1 inch. Either the mouse pointer should change back or all decimals should stick.
OpenDimTest.dwg. Manage> Modify> Replace Model Reference and pick DimTestDerive.
ALL dims disappear and the origin indicator goes sick.
I have a plot plan, that is rotate about 31 degrees off true north. So when I draw inside the plan, I rotate the UCS to be able to follow a "plant" north.
> UCS > point 1 > point 2 (along x axis) > point 3 (along y axis)
> PLAN > enter > enter
Now, I'm trying to measure a distance between 2 points with my drawing rotated along a new UCS. However, it keeps giving me the measurements as if it were still in the WORLD UCS.....so my x and y values are weird numbers instead of the nicely rounded numbers to which I have offset from a certain point.
> DIST > point 1 > point 2
How do I get my distance to show me what the x and y distances are in the UCS that I have rotated to, instead of showing me the x and y distances based on the WORLD UCS?
I am still unable to assign a viewport color override to a 3D solid xreffed into the current drawing. Is there a fix yet? The override color shows in the vieport but when executing a "hide" or plotting the object reverts to it's original color. It would seem to be a large enough "bug" to warrant a hotfix
I'm using Sheet Set Manager in Autocad 2011. I'm using 'page setup override', and as plot area 'print extents'. So far, so good. Until someone forgets something outside the title block, and the extents feature is not good anymore (several people working in the same projects).
So, I decide to use as plot area 'Layout' instead, typing the X & Y to determine the area to be plotted.
Now, the setup "override" doesn't override. It’s using the drawing plot area from the drawing itself, which completely defeats the purpose. Am I missing something?
I have a text style called standard2 in a drawing, I put all text whether it be in blocks, dimensions, mtext, dtext everything into the style I want. Purge the drawing which gets rid of the style, save it, close it then reopen. I then get Standard style reset, existing objects moved to standard2 and now the standard2 style is back in the drawing. This problem is only affecting some drawings and not all drawings.
I'm trying to override the F9 key with an AutoLISP subroutine invocation. However, though I have redefined the Temporary Override Key (associated with the F9 key) in the CUI editor, the F9 key nevertheless still triggers the default Toggle Snap Mode behavior. So it's not accepting the redefinition even though the new definition persists between AutoCAD sessions.
I need to change the color of a layer in one of my viewports, which I set using the layer manager. That change doesn't show up in the viewport however.
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 have an xref in my drawing. I am trying to use a VP override to make a layer plot with a lighter lineweight. I have changed the layer to number 9 (set to plot light) in the viewport and the layer changes color. When plotting the layer does not plot with the correct lineweight. The object color on the layer is set to bylayer. Visretain is set to "1" What is wrong? Why isn't the layer plotting correctly?
Im trying to show some measurements in layout view. But when i dimension between 2 points i get the number 71,84. When i use the measure tool in model view i get 1150mm which is the correct length.
Sure there is some simple reason why the two arnt coming in with the same value. Also it isnt an issue with Units as i have checked both and they are both in millimetres.
I am using AutoCAD 2012. I am trying to use ordinate dimensions for the first time. So far, when I want to add the X and Y dimensions for a particular feature in my drawing, I choose the "ordinate" dimension type and then I select my feature. I drag my leader horizontally and it gives me the Y dimension. Then I choose the "ordinate" dimension type again, I select my feature again, and this time I drag my leader vertically and it gives me the X dimension.
I like how this works, but I think I would like it better if, rather than having two separate leaders for X and Y dimensions, I could just have one leader that would show both X and Y dimensions separated by a comma...i.e. something like [X:5.0; Y 7.5]
I have some aligned dimensions in model space - they look ok, text is oriented according to WCS. Also I have some viewports with UCS (I used commands UCS, PLAN) where dimensions look wrong, text is not oriented correctly. Is it possible to "update" dimension in viewport to orient text as in model space?
Programmatically created dims in viewports oriented as in model space, not considering current UCS.
When I make a layout with a part of my drawing in a viewport, I switch over to paperspace to draw dimension lines in it. Although the layout is displayed in another scale (e.g. 1:100) it puts the right dimensions at the drawing.
But now a problem appears:
With one of my drawings the layout does not put the right dimensions at the drawing in paperspace. I really don't know what went wrong. Strange dimensions appear, as if there must be a strange scale factor somewhere. (Dimlfac=1)
I'm working out some bugs that have cropped up now that I've upgraded to 2011. For starters, I can't seem to be able to snap to existing dimension lines like I used to, even though I have almost all of my snap types activated.
When 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.
I had the need on occasion to dimension in Paper Space. I set up a "Dim Style" to accomplish this in either 1/8" or 1/4" Scale. The problem I am having is the consistency of the actual dimension.
For example: I could draw a simple box 10'x2'. When I dimension in Paper Space, sometimes it correctly displays the dimensions and sometimes it incorrectly displays the dimension.
I attached 2 screen shots of what is happening. Notice the dimension on top of the box shows 10', but when I dimensioned the bottom of the box it shows 480'. This seems to work at random.
The other screen shot shows the Dim Style settings I used.
I am unable to see the dimensions that I measure using power dimensions as per the attachment on the drawings itself. If i want to see it, I have to select the green line, and right click and select the line and select standard as the dimension style. I did not have to previously do all of this.
I've completed a drawing, with dimensions and everything and I have to reduce it to 1:2 scale to fit my drawing frame. How do I do this without changing the dimensions? Every time I reduce it the dimensions halve as well!
We do a lot of labeling in paper space and have been encountering a problem with our dimension command mislabeling lengths and widths. Please see attached DWG. The road width should be 24' and its labeling it 880'. BUT measuring hoizontally it seemed to work fine. Really strange.
I am using the dimension command and snapping nearest and perpendicular. If I just click without using osnap it seems to work.
We tried using the DIM / DIMFLAC / V / and selectiong viewport
The funny thing is that I dont have this problem with every drawing. Just some seem to have this glitch.
I have some serious fight this morning with AutoCAD. I have to dimension my drawings properly so it can be build. I did some already, a few aligned dimensions in an layout snapping on modelspace objects. when i put them all is fine and right dimensions.
BUT after i saved, closed the file and opened it again those dimensions are everywhere exept where i put them originally. And no the modelspace objects are not moved.
How can this be? can i solve this? or is this a know bug for AutoCAD 2012? i can't check all the dimensions before publisching again and again.
Why is it that some dimensions in a viewport are out of sync with the rest of the dimensions? Eg. a correct dimension is 240, but the next time you dimension the same distance, you get 24 as a dimension figure?
Also, in a long run of continued dimensions one or two of the dimensions is out of scale? I have tried making all dimension Annotative, same dimstyle, etc.
I think sometimes Autocad forgets that it is in a viewport, so some dimensions are correct to the viewport scale while others are to the limits of the paper size?
I am looking for a way to get my dimensions to round up instead of to the nearest.
For example... when I have one line that is 11-15/32" and one that is 11-17/32" and I need them to round up to the nearest 1/4". I want it to round up, showing 11-1/2" and 11-3/4" but instead i get 11-1/2" for both.
When dimensioning in paper space and move or make any adjustment to the viewports the dimensions go haywire and move of the parts but not all dimension and not all viewports are doing this. I'm using the same dimension style and templates that I normally use.
