AutoCAD 2013 :: How To Set Up Scale Of Known Distance On Photograph
Apr 23, 2013
I am trying to set up a scale of a known distance on a photgraph that I have put in autocad. I know that this distance is 100mm, and have tried to work out how to mark this known distance, and then be able to work out the measurements of other dimensions in the photograph, including non-linear measurements. Is this possible?
I am trying to find a routine that will allow me to offset an arc by a distance and to a scale.
The offest command is very limited as to how far I am able to offset without the boject completely vanishing.
I am trying to make a flat pattern from a cone or something close to it. The routines and programs that I have found do not quite accomplish this very accuratll. They are always off on the upper and lower arcs and on the distance between the arcs. Tho this would not completely sovle my problem, it would allow me to get the distance between the top and bottom correct.
I am trying to oTrack distance from the top circle edge of a cylinder to a certain distance ... whenever i try to do that ... it either track to x and y .. but not in z :/ ... the video i have on you tube he did it so simply and it seems to be easy .
I am not sure what is wrong .. but i heard parallel and perspective view could make a difference .. i actually try both :/ ...
I have a photograph of a house and measurements of the porch columns, windows, etc. When I scale it some of the measurements are correct while others are way off. The photo is angled a bit but I am only concerned with the porch.
I have been using AutoCAD for many many years and only recetnly discovered the "MEASUREMENT" command. This has allowed me to work out why some hatches are larger than others but I still don't understand hatches! I have a few questions,
Lets establish some things I know,.
1) MEASUREMENT 1 is for us metric people. 2) HPSCALE alters the hatch scale for all drawn hatches after 3) Default for HPSCALE is 1 (tiny in metric)
Now the questions:
1) Does the hatch scale relate to any type of distance variable? e.g. the gap between the lines in ANSI31 is say 5 times the hatch scale or is this totally and unterly random?
2) If there is a logic behind it, does this apply to all hatches in ACADISO.PAT? e.g. scale of 10 produces 10mm gaps in all hatches? (I know it doesn't but there must be some logic to it? Surely?)
2) If the hatch scale is not logical (see Q1) what is the point in the meaurement command and ACAD.PAT and ACADISO.PAT files?
I have just updated to Autocad 2013. While working on existing drawings (previously created in V2012), I am having issues with the SCALE command. Most times, but not always, when I add a line or block, with a base point on an existing line or object and try to scale it, I get an "extremely small scale factor ignored" message, although I did not get a chance to enter a scale factor. While it appears most times, but not always, if I draw a new line in empty space on that same drawing, I am able to use the SCALE command without problems. I also have the same issue when trying to scale an existing line or block, most times but not always.
Here is a copy of the command line while I am trying to make it work:
Command: l LINE Specify first point: Specify next point or [Undo]: 100 Specify next point or [Undo]:
Command: sc SCALE Select objects: 1 found Select objects: Specify base point: Specify scale factor or [Copy/Reference]: Extremely small scale factor ignored.
Command: SCALE Select objects: Specify opposite corner: 1 found Select objects: Specify opposite corner: 1 found, 2 total Select objects: Specify base point: Specify scale factor or [Copy/Reference]: Extremely small scale factor ignored.
If you notice, it does not give me the chance to enter a scale factor. As soon as I pick the base point, it skips over to the error message, yet displays the scale factor prompt with a blank factor. I'm experiencing this issue on various files (not all but most), so I don't think it is a corrupt file. Why I get this and if I can correct it?
I am looking to extract natural noise from a photographs material and create a black and white layer out of it, but I am new to photoshop and unsure how to proceed with this.
For example, here is a photograph of a hard plastic gun.
I have seen on forums where users will find a good reference image and use it to create a new black and white noise picture utilizing the reference.
For instance the hard plastic noise from the gun, might look like this once extracted and done correctly.
When I open a new drawing in my AutoCAD 2013 that I just recently installed last week, I encounter a problem that I am not familiar with from previus versions of AutoCAD I have worked on. First of all, the units default to decimal, and I want them to default to architectural, with feet and inches. I have to type UNITS in the command line every time I open a new drawing in order to adjust this. I have AutoCAD for Architecture 2012 on another computer, and the program automatically defaults to architectural units upon opening up. Just to let you know, the program I am having this difficulty with is part of a package called Autodesk Building Design Suite 2013. I was under the impression that it included AutoCAd for Architecture, but I think it has only standard AutoCAD.
The scale of the objects I draw vs. the scale of the drawing field is very out of proportion. What I mean is, when I open a new drawing and draw a 30' -0" line, the line appears so long on the screen that I cannot see the whole object, even if I zoom out to the maximum. I should be able to see the object in it's entirety. In fact, when I draw a line that is only 12" long, even when the zoom is all the way out, the line looks huge in length. I have tried adjusting the units to the architectural/inches setting of course, and I have tried adjusting the scale in model space from 1:1 to 1/4'=1'-0", but nothing is working.
I am trying to insert a block into a file in Acad 2014 and it comes in too large. If I insert the same block into the same file using Acad 2012 it comes in at the correct scale. Doesn't seem to matter if insunits is 0 or 1, or insunitsdefsource or insunitsdeftarget are also 0 or 1.
There must be some variable or variables I'm missing.
I have a block that i would like to scale based on the plot scale when plotting.
We set up our drawings full size and occasionally we want to plot them at half size. We do this by setting the plot scale to 1:2 (custom) in the plotting dialog. We have a few blocks that we want to print at the same size on paper, essentially become twice as big.
Is there is a way to fix the size or just set a few scale states and have them automatically adjust based on the plot scale (not drawing/annotative scale)?
I have located steel beams of an existing building roof frame. I am being asked to provide a distance from the theoretical roof to these points. The roof is sloped and I can create the sloped roof plane but I am unsure how to get the distance from the point to perpendicular to the theoretical roof slope, not the difference in elevation. Also would it be possible to label or make a table?
I used direct-distance entry to place the dimensions 3/8 away from the object lines... needless to say, while most horizontal dimensions are 3/8 away, the vertical and inclined dimensions are not. see attached. other than creating construction geometry and physically moving the endpoints of the arrows to the correct location, is there any way of getting this precise and correct the first time i do it?
How do I control the 'auto' option under DIMSPACE?
I have found that the entry listed as 'Jog Height Factor' under the 'Linear Jog Dimension' are of the 'Symbols and Arrows' tab of dimension style does the trick. However, does that control a variable?
I keep trying to draw a line by bearing and distance using the format @50.00'<N80d04'30''E. Everything enters but when I enter the last command of the bearing and hit enter it stays in the red boxed outline and does nothing. Upgraded to 2014 and trying to get things set for drawing property boundaries. Tried setting the units to surveyors mode and such but nothing works.
I thought there was a setting for this? I want to adjust the Osnaps so they appear further away from the point. IE: As I want to pick the quadrant I have to get so close to the quadrant before the osnap shows. I can't remember the variable to adjust this distance.
I was wondering if there is a way for me to setup Autocad so that instead of putting in S 88d20'12" W I could put in something like S88.20.12W so that I don't have to mess with apostrophes or "d." Also, can i do something similar with distance settings? Where instead of saying 5'-6 1/2" I can say 5.6.1/2. I know I could convert the measurements into decimals, but that would waste the time I would be saving with a faster input method.
this Nudge command. Seems like it could be very useful, and I must say i like the IDEA of it (to those not familiar, you hold CTRL and hit arrow keys to slightly shift an object) but how to set the distance default on it. It seems to me to just move things by whatever distance it feels like.For my job specifically, I need 1/2" increments. how to set that variable?
how to edit the line space distance for the dimension text. I can change the style, size and several other features. But the line space distance is the one thing I can't seem to edit. The only solution I know of and use is exploding the dimension and then the text turns to mtext and the option becomes available. But then if the section changes to a shorter/longer area, i have to go through several steps with the exploded lines. how to edit the line space distance for the annotation in the dimensions. i have also attached a pic of my issue as well.
Did 2013 change the way Direct Distance Entry is handled?
Say I want to start a line a distance of 3 from another line using Otrack and a running endpoint snap. Before, I could just hover over the existing line's endpoint, move the cursor in the right direction, and enter 3 on the keyboard. Now in 2013, I need to have Dynamic Input (F12) turned on to get this behavior. 2012 was not this way.
My units are set to decimal. In acad 2004, the dropdown list showed options like 1"=50' In 2013, it shows options like 1/32"=1'-0" How can I get it to display such as 1"=50' like before?
I have a drawings with drawer frame (margins left are 25 mm and rifgt, top and bot margins are 5 mm). I don't know how to export them in pdf in right scale. I always got cut off edges or i see outer line.Drawing example is in attachment i need to print it in a3 paper. Explain me whole process converting drawings to pdf on my drawing.
Is it possible to insert a scale bar? I have searched all over but the only instruction I got was to click insert scale bar in the annotation pallette, but no such thing exists. Surely this should be easy enough?
So if I am in a layout page and I plot the sheet directly to our printer the drawing comes out to scale.However if I plot to PDF using DWG to PDF.pc3, and then print to printer it is always slightly smaller around 10% to 15% smaller.
