how to convert "real world" angles of elliptical arcs into those shown in a dxf file?
Say that I have drawn an elliptical arc with its start angle on 210 degrees and an end angle of 324 degrees. The values in a DXF file, for an elliptical arc, have something to do with the contant "PI" (3.14159). I know that a full circle is 2*Pi but how to do this with elliptical arcs!!
Im drawing in isometric view and want to change the default drawing angle from 30 degrees to another angle.

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.
View 4 Replies View RelatedI 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".

A question regarding converting angles between co-ordinate systems in AutoCAD .NET.
Im creating my first little utility to form selected block attribute references into a nice neat list. The current version takes a selection of blocks and a list insert location and then moves the attribute references to the location and rotates them to WCS angle of 0.
I now want to expand the program to make it a little more flexible and allow you to form the list parallel to the currently selected UCS x axis (the i.e. and angle of 0 in relation to current ucs's).
I have managed bumble my way through and transform the attribute positions correctly to form a list relative to the current UCS but am strugling on how to work out in code what the equivlanent WCS angle value would be.
I have done some calcs using .net framework to calculate an angle between two vectors (see code extract below). But this introduces a small error into the angles (i.e. if my ucs is set rotated 45 degrees around the zed and i use the below maths, the resulatant angle is 45.0000002 when read in acad afterwards).
Matrix3d ucsCur = ed.CurrentUserCoordinateSystem;
CoordinateSystem3d cs = ucsCur.CoordinateSystem3d;
// the below seems to work by calugulating the angle between two vetrex using .net maths class but this introduce a small accuracy error. Is there a better way?
Double rotAngle = Math.Acos((1 * cs.Xaxis.X) + (0 * cs.Xaxis.Y) + (0 * cs.Xaxis.Z));
//set the attribute reference rotation to the calculated WCS radian rotation value "rotAngle"
attRef.Rotation = rotAngle;
Im sure there is a better way built into the managed autocad wrapper using a tranform matix and the ucs vertex information but dont really know how to go about it. Any links explaining how to work with the UCS in .net.
For some reason my angles are all way off. I type line 3<65 and it goes nowhere near 65 deg. My coordinate system is normal. I attached screen shot.
you can see command line on bottom and line not at 65 deg.

View 1 Replies View RelatedMaybe I've just been doing it wrong for the last 5 years, but the Angle constraint is obnoxiously unpredictable. When I constrain a part in an assembly with an angle constraint from the assembly origin plane (or anything else), Inventor always has two solutions; a positive and negative.
Is there something I'm missing here, or is just a design flaw we have to live with?
I am doing takeoffs from a CAD drawing. Without getting too deep into it, I have one origin point, and then I have 200 or so points around the origin. I'm trying to find the fastest way to get the X offset, and the Y offset between each point and the origin.
Right now I'm drawing two lines to connect each point to the origin, then using PROPERTIES on the lines where they meet to get each length - I need to be able to see the numbers on the screen for a second while I copy them into a database. But I'm wondering if it would be easier to write a script, or if there happens to be a tool that could do this with fewer clicks.
I'm trying to sweep it around shape like this But it won't, it says "The selected path curve is not valid." - so what do I do? (it is polyline) Is there maybe some other way to get this 3D shape fast?

View 5 Replies View RelatedSeveral 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?
