Getting the outside measurement (225° in this example) is done by following the prompt. To get the angle on the arc, just select anywhere on it. The example above shows 3 common uses of this tool. The command works similar to the linear dimensions (see a pattern?). The measurement of the angle is defined by your dimstyle, but degrees is standard. Angular dimensions will display the angle between two objects. Not every dimension gives the reader a length. You can also select Angle for your text to match the angle of line (just select 2 points on the line you are dimensioning). Also Rotate is missing to avoid confusion and errors. Of course, there are no option for horizontal or vertical placement. You’ll see that command line prompts are almost the same. It will create a dimension parallel to the angled line. You can also use this on any 2 points that are also compatible with the linear dimension. The big difference is that it works with lines or distances that are not square to the UCS. The Aligned dimes ion works just like the linear dimension. This is a lot quicker and more accurate as you don’t have to worry about picking the wrong Osnap. You’ll also notice on the first prompt, you can, Press at this point, and then you can just select the line instead of the two endpoints. This will create a vertical dim, but you select this when you place your dimension line. This will create a horizontal dim, but you select this when you place your dimension line. This will place your text at the angle you specify You don’t need to use these, it doesn’t really affect your dimensionSE Note that there are some options at the command line: MText / Text Specify second extension line origin: SELECT SECOND POINT Specify first extension line origin or : SELECT FIRST POINT Just pick the two endpoints of a line (or any two points) and then place the dimension line where you want it. To create a linear dimension, either use the icon or key in DIMLINEAR. Make sure that it is not to close to overlap the object and not too far to confuse which object you dimensioned.
It’s good practice (thought not always allowed by time) to have your dimensions at a consistent distance from the object. This is the most commonly used dimension and is very easy to use. Linear dimensions are used to create a dimension that measures a line that is either horizontal or perpendicular to the UCS. This section will describe how each one works in mre detail. You have most likely already used some of the common dimension types like ‘linear’ or ‘radius’.

Learn when each dimension is needed and how to use it. If your dimensions are inaccurate, you will not be working in CAD for very long, no matter how accurate your drawing is. Dimensioning is used to let the drawing reader know what size each length or curve is, without having to open the drawing. A good AutoCAD drawing will convey the needed information clearly and accurately.
This tutorial will explain the different types of dimensions that commonly used in AutoCAD and help you understand their differences.
