hello my name is Randy Dobson and I'm an instructor here in the Houston Texas area and this video will be covering the AutoCAD command polygons which if you look on your screen it's actually shares the spot with rectangle they do similar things kind of like trim and extend and fill it and chamfer so to make it work they little share here now polygons one of the first things that ask you is how many sizes you want to have now when you create a polygon whatever sides you give it those will be equal sides so if you did three then you would create an equilateral triangle okay if you did four you would do a square because a square all four sides are equal and then of course you go into Pentagon hexagon decagon octagon all the different guns and so they're based on a center and that's why I drew this circle over here but just to again just to let you know if I did ten sides all ten of these sides let me just do something here real quick oops I wanted it I'll stop but it would do it differently but have you tried it this way so on as you can see they're all the same size lines okay and for some reason my snaps are not on here we go get rid of some of this other stuff there we go so just to kind of give you a history on a polygon you the more sides you do obviously it'll look more and more like Epcot at Disneyworld like a golf ball with all the dough with all the dimples on it if I did a polygon and gave it a hundred sides well when you look at it like that that looks like a circle but if you zoom in more and more you'll see that those are lines in there so don't use this ever as a circle I just want to give you that reference so when you do a polygon it's based on two things is looking for a radius and it's looking to where you're doing it on a circle do you want to be inside the circle or outside the circle okay giving the same information creates two different something the same radius can create two different polygons I'm going to go with polygon and I'm gonna give it as two five sides and it's asking for a center I want to use the center of this circle now it's asking me do I want it to be inscribed which is inside the circle or do I want it to be circumscribed which is around the circle so I'm going to go with inscribed and it wants a radius and I know my radius is five so I'm gonna give it five and there it is as you can see it's inside that circle now I'm going to do it again same thing five sides right here I'm going to pick the center of this circle again on this side I'm going to go circumscribed and I will still put in a five-foot radius now as you can see is going around the circle now like I've mentioned in some of my other video which one you use if I if I asked you in the classroom I said which one of these are you going to use when you do an assignment your answers should be whatever information I have you may have something that gives you the dimensions that show this being you know from here to here which that would mean now let me let me just do that real quick see if it'll let me okay like you know if I've got this and I'll move this and say it's it's like that then I know that if it's giving me this radius I'm going to circumscribe it but I also know that if it's giving me distances like this it's giving me a distant like that and I know it would be inscribed so the nice thing is if you do it wrong do one way just undo it and go back and redo it the other way but this is something that you can use on some of your assignments I think one of them you actually have an equilateral triangle like this you just have to rotate it let me just do that if you haven't watched the rotate video watch that I'm going to rotate this 180 degrees and you can actually use this to create one of your assignments but the polygon again I want to let you do this equilateral triangle I'll let you create a square besides everything else but just remember all of these sides are equal and they're all one one item I'm just going to get move if I move it out over here okay so nice tool instead of trying to draw a square by line line line and so on are doing you know 60 60 and 60 degree angles it's so much easier just to use a polygon and that concludes my video on polygons thank you
