AutoCad :: Determining Angle Between Two Lines

Mar 24, 2009

I wish to determine the angle between two lines (that meet). I know how to do this manually, although does AutoCAD have a built in command similar the DI command maybe, or a LISP?

AutoCAD Visual LISP / AutoLISP :: Determining Number Of Lines In Multiline Attribute

Sep 26, 2013

I am basically trying to determine how many lines are in the mutliline attribute. I have abandoned the idea of directly trying to find the the number of lines and have moved on to trying to fine the height of the multiline attribute. I have included the lisp and sample drawing that will draw a box of the boundingbox around the mutiline attribute. 

This block as originally a dynamic block that different visual states. I have tried using the bounding box option on the block itself, however, if there are blocks hidden with the visual state, it will draw the bounding box according to the largest element in dynamic block every time. So I need to determine the height of the multiline attributes instead and adjust the dynamic block accordingly.

AutoCAD 2010 :: Plotting Lines Using Compass Direction For Lines Angle

Apr 25, 2012

i am doing a simple project making a survey plot for a piece of land that will be broken into subdivision. all measurements are of my starting point. after plotting the starting point i try to draw line that is 113 feet long and at a bearing of N 5d W i have no problem entering this data but when i hit enter it draws a straight line. now i know 5 degrees is much of an angle so i thought maybe it just looked straight and tried to plot the next point which was 542 feet from the last point at a bearing of N 39d E but once again after i put the info in and hit enter or space it would plot a line of the proper length but vertical, not the proper angle i need it at. here is how i would put in the info:

first i choose the lne command and choose my "beginning point" as that starting point for my line then i type 113<N 5d W for the length and direction and hit enter. when i do this it plots a vertical line of the proper length but wrong angle. what am i doing wrong? i have ortho set to off and idk what else to mess with

AutoCAD .NET :: Angle Between Two Lines?

Aug 10, 2011

II am looking for two things...

1) A good explanation of Vector3d.  I have been unable to find a good explanation in the ARX documentation or on the online .Net developers guide.

2) Need getting the angle between two lines.  The lines in question are in an orientaion similar to the greater than operator ( > ).  I have attempted to use the Vector3d.GetAngleTo method to get the angle, but I do not understand it enough to be successful!

AutoCad 2D :: Measure Angle Between Two Lines?

Jul 7, 2012

Several people recommended DIMANGULAR. I have some concerns using this method because it is dependent on the precision of angular units in the drawings DIMSTYLE settings. For example, if a drawing file's DIMSTYLE has a precision set to the nearest whole decimal degree or only shows degrees and minutes but not seconds then the angle may appear at a certain angle, let's say perpendicular at 90 degrees. But in reality the angle might be slightly less than 90 degrees, if its off by a few seconds.

I learned an alternative way by selecting both lines and typing the LIST command. The Angle in XY Plane will show the measurement for each segment in bearings, not azimuths. I simply find the difference between the Angles in XY Planes for both lines to determine the angle. I have a few concerns with this method.

1. How do you add subtract bearings measured in degrees, minutes, and seconds? For example, N 76d3'18" W and N 13d56'42"E? I "think" there are websites that can do this? Can this be done directly in AutoCAD through QuickCalc or some other tool?

2. Lines, but not polylines, have Angles in XY Planes in the LIST command. Is this because AutoCAD assumes that polylines will be composed of more than one segment (and each segment with a possible different angle)? Is there anyway to measure the angle of a single one-segment polyline?

Is there a DIFFERENT way between the two methods I just described to measure the angle between two lines (and two polylines) in AutoCAD?

AutoCAD Civil 3D :: Maximum Angle Between Adjacent TIN Lines

Sep 12, 2012

I am trying out this option, and am noticing that whenever I close and reopen the drawing with a surface that uses this option, it resets my maximum angle from whatever I have it set to, to 90 degrees. Am I missing some setting that defaults the max angle to 90 degrees on drawing open? Or is something else going on here?

AutoCAD Visual LISP / AutoLISP :: Available For Angle Between Two Lines?

Nov 28, 2011

i know DIMANGULAR command will let me draw a dimension to display the angle between two lines, but is there a way for my commandbar to show me what the angle is rather than draw a dimension?

I often want to simply know the angle but not display it in the drawing, and it'd be good if there was a command/lisp which showed me in the command line area, or perhaps a pop up window, similar to what the TLEN lisp does here: URL....

AutoCAD Visual LISP / AutoLISP :: Calculate Angle Between Two Lines

Apr 10, 2002

I have about 30 profiles with water pipe lines that I need to measure all their vertical angles. since the vetical scale is exaggerated so I can't use the acad angular icon tool bar. Only thing I cant think of is to block each run then import them back in at 1/10 in y direction. How to get this done faster or more direct by any other methods.

AutoCad :: Angle To Put A Line Of Specific Length Between Parallel Lines

Jun 23, 2012

I am drawing a diagram to describe a mathematical word problem. Since it is easier to visualize with a drawing, I want to draw it using the given dimensions. But angles used in the diagram are unknown and are not needed for the answer to be calculated, so the only way to draw this freehand is to guess at the angle resulting in the correct distances to be off.

Here is the word problem: There are two ladders, one 40 feet and the other 30 feet, each touching the base of one of two buildings and leaning against the other building. If the ladders cross 10 feet above the ground, how far apart are the buildings?

So for my drawing, being rather simple considering what AutoCAD can do, results in this:

Can AutoCAD calculate the angle needed to place a line of a given length between two parallel lines that are a distance apart less than the length of the line to place between them, having the endpoints of this line touching the parallel lines, fitting exactly?

For the word problem, the distance between the two parallel lines is what needs to be solved and the math is quite invloved, having to find the roots or solution of a quartic equation. (I have the solution figured out to be 26.03287754 feet)

What I am afraid of is that this would require to program an AutoLISP routine to create a new command that one can call from the command line. I see it using the the measure command with relative and absolute co-ordinates. This may be far from a "beginner" question. I can do this quite easily on a peice of paper: having two parallel lines drawn, take a ruler and placing the "0" mark on one line, then adjusting the angle until the desired length just reaches the opposite parallel line. I used to use this trick quite often when drafting with pencil and paper to divide a distance into a required number of even amounts, so this can't be that difficult to do with AutoCAD!

GIMP :: Add Angle Measure Lines To Image

Feb 6, 2013

I use it to measure angles of micrographs (images taken with a microscope) --- the angle measure tool is great, and easy to use! I would like to be able to save the angle measure "rulers" into the image, for documentation purposes. Is there a way to incorporate the angle "ruler" in a layer or overlay in the image so that I can save a new file with the ruler "burned in" (for lack of a better term).

I will also be adding the text of the resulting angle measurement --- it would be cool if the result of the angle measure could be automatically added as text to the image (preferably in a different layer than the original image). I can type it the result with the text tool.

I'm trying to match the style of an illustration done by someone outside my company; all the lines taper at both  the ends like an actual brush stroke, but when I used the brush tools I have to change the angle to get the tapered look - is there a trick to this? It's not efficient to have to stop and change the angle of the tool for every stroke -

Photoshop :: Adaptive Wide Angle Causing Wavy Lines Even Though Marked As Straight And Vertical

May 24, 2012

I have the beta installed but I also installed the trial of CS6 on another computer.. Both do the exact same thing with the Adaptive Wide Angle filters. I set a line as straight, mark as vertical (2 lines really) and then process.  The lines that are vertical come out wavy... best way to describe it..
I add the 2 control lines to the very outside most windows where the windows meet the brick... This is a closeup of the output...   I don't know when straight lines became waveforms.. but they do with this filter!

AutoCad 2D :: Rotate An Object To Match An Angle Without Knowing The Angle?

Oct 5, 2011

Is there a quick way to rotate an object to match an angle without knowing what the angle is? I am using AutoCAD 2011 now. I was using 2007 and I had an add on command the would rotate an object using a base point and picking the two lines that make up the angle, and it would match the angle you wanted. I can not get that command to load in 2011.

AutoCad :: Rotation Angle Doesn't Match Angle Inquiry

Jul 25, 2012

I have a property line that is N 36d19'52" E but needs to be N 12d52'18" E. The obvious and calculated rotation angle would be 23d27'34" but when I rotate the line by the calculated angle it doesn't rotate to the right angle. It's off by 0d11'10"!? When I draw a line by bearing at N12d52'18" E and inquiry the angle between the property line and the drawn line the angle difference is in fact 23d27'34".

AutoCAD Inventor :: Determining A Counterweight?

Jul 16, 2013

Not sure if this is something I'm able to do in Inventor...

I have a "damper", it's more or less a diesel exhaust flapper type vent, that hangs upside down and is held in the horizontal/closed position by a counterweight.

Typically we would experiment in the shop with the counterweight quantity and the length of the arm required to get the proper operation of the damper/flapper in respect to the air/exhaust flow.

Since we know the axis along the shaft for the flapper and the weight of the flapper and it's bracket on the there a way to figure this out in Inventor? Obviously it still may need to be dialed in/tweaked...but I'm not sure if it's even possible.

AutoCad 2D :: Determining The Area Of A Hatch

Apr 19, 2011

Essentially, I have an odd shape that I fill in with a hatching. SOMETIMES, it will give me the area in the properties window (or when I use the list command). but other times, it will not give me the area.

I just hatched 4 different (but same general shape) areas, and on 3 of them CAD was able to compute the area, but not the 4th hatched area.

I created all 4 hatches using the exact same steps, so I'm not sure what I could be doing wrong. The CAD Tech at the office cant seem to figure it out either .

AutoCad :: Determining Scale Of Drawing

Feb 17, 2013

I need determining the scale of a drawing I got from the internet in ratio form. the drawing itself has a little scale bar in the corner, however, since i do not know the measurements of the actual structure i have no reference point and therefore cannot figure out the scale in ratios.

I read on here that you can use general reference point such as the average dimensions of a door/window ceiling etc. but the drawing is a longitudinal section of a church, namely, Temppeliaukio kirkko, which has no 'standard' dimensions.

I need this drawing in 1:100
