In this video, Shaun Bryant demonstrates how to specify length and angle with Dynamic Input in AutoCAD LT.
- [Instructor] We're starting another chapter now in our AutoCAD LT Essential training course. And what we're going to be looking at now is working in an AutoCAD LT drawing. So, I'm gonna show you some of the typical things that you might use and work with when you're creating drawings using your AutoCAD LT. We've got a new drawing for you. You can download it from the library, and it's called TypicalDrawing.dwg. There ya go, that's nice and original for you, but it is going to be a typical drawing, and we're gonna do some typical things that you might do in a drawing.
So, we're gonna have a look at placing a line in an AutoCAD drawing, but also how we utilize the dynamic input to place the length of that line and the angle of that line. Now, you might think that's a really, really basic thing to do, but there are ways and means of doing it, and little workflows, and little tricks that you might not be aware of. So, we're in our TypicalDrawing.dwg file. In the layers panel, in the home tab, just make sure that you're utilizing the objects layer.
So, click on the word objects there, and that will make it the current drafting layer. Now, what we're going to do is literally just use the line command, and I'm gonna show you how to utilize the dynamic input. Now just before we do that, make sure that your dynamic input is on. So, you'll see down here on the status bar, there's my dynamic input icon, it's blue, which means it's on. Now if you don't have a dynamic input icon like that, it looks like a little box with a cross next to it, you need to click on these three lines here, and just make sure that dynamic input is ticked, and if it isn't ticked, just click on it, and it will be ticked, like that, click on the little three lines again, and you'll have a dynamic input icon here.
Now, if I just right-click quickly there, I can look at my dynamic input settings in my drafting settings. Although I don't change any of this, I tick those two boxes there, and I leave all the settings as default settings. It's up to you if you want to investigate those settings, by the way. I'm gonna leave it as it is and I'm just gonna click on cancel so that it doesn't make any changes. Let's go up to the draw panel now, on the home tab, and there's the line command. So I click on the line command, and I come into the drawing area. Now I'm gonna start sort of down here, bottom left, and I'm just gonna click once and now as I move the mouse, I've specified the first point of my line, it's after the next point of my line.
Now the lovely thing about dynamic input is you get three bits of information. My polar tracking is on at the moment. You can see that on the status bar as well. Now, we did mention that previously in previous videos, and it's actually set to 45 degree angles, so I've got a polar tracking line there shooting off into space, so to speak, telling me I'm at an angle of 45 degrees. The distance there is 97.3176. Now, I don't have to go with the 45 degrees.
What I can do is, as I move away from the polar tracking line, the dynamic input picks up the angle as well. I might want 60 degrees, and I might want a certain distance. So, I type in the distance box one, two, five, there's the distance, and all I've gotta do now is press the tab key on the keyboard. That locks down the distance for me, and I want that at 60 degrees. Press the tab key again, and they're both locked down to an exact distance at an exact angle.
If I now left-click once, that locks down that point. Can you see? And now I can go for the next point on my line, so now what I'm doing here is creatin' a group of line segments. These aren't actually all one line. I'm usin' the line command so each segment of this group of lines is an individual line. So what I'm going to do now is I'm gonna come across here, and I'm gonna give this another distance of 150, but using the zero polar tracking line. Now, even if I didn't have polar tracking on, it would still find the angle of zero.
I could just move it around with the mouse, or I could actually type in a distance of one, five, oh, like that, and then tab again and put zero in that box, and it would pick that up as the angle, and then tab again. It's locked them both down, 150 long at zero degrees. I left-click again and it's locked off that particular line segment as well. So, what I'll do now is I'll basically come down this way, and I'll wanna come down to an angle of 60 degrees again.
Now, hang on a minute. I'm going in the opposite direction. That should be a complimenting angle, shouldn't it? If you think about it. I'm goin' in a different direction, but this is what the dynamic input's used for. It's always an angle that is relative to the last point placed. So now, I can put in my one, two, five again, my distance, press tab again, and put in 60 degrees again, like so, press tab again, it locks it all down, and I left-click once.
So, what I've got now is two lines that both go at 60 degrees, but in opposing directions. Now the nice thing is, what I can do now, is I can right-click, and on the shortcut menu there, if I click on close, it will take me back to the point I started, and there's my nice little shape. I'll just pan upwards a little bit. Where I've drawn that completely utilizing distance and angle in the dynamic input.
