When dimensioning an angle, AutoCAD is quick to give you your angular measurements as well as the measurement of the opposite angle or supplementary angles. The problem arises when you want to dimension an angle greater than 180 degrees. At first glance this might not seem possible. In this lesson, we're going to learned how to dimension a reflex angle, an angle that exceeds 180 degrees. On my screen, I have an architectural example. This geometry represent a door that is mounted on a double hinge, so it swings in both directions.
Let's say I would like to dimension the full range of motion of the door. To do that I'm going to select the Angular Dimension Tool and since my angle is greater than 180, I'm going to press Enter to use the Specifying Vertex option. Specify Vertex allows me to measure the angle by clicking three points. I'll specify the angle vertex using the Intersection objects mapped. I will then click to select this line and this one to find the intersection. I will then grab this end point to identify the first line of the angle and then I'll select this end point to identify the second line. I can then pull out my measurements and click and we can see that this door has a 290-degree range of motion.
In fact I'm going to select this one more time and I'll grab this grip and I'll pull the value up to here so it's little easier to read. More often than that, when you dimension an angle you'll be expecting a measurement of less than 180. However, if you need to dimension a reflex angle it's important to note that AutoCAD can do that too. Just use the Specify Vertex option.
