In this drawing we're going to draw some objects utilizing our Objects Snaps. Now the first thing we need to do is we need to make sure that our Object Snaps are switched on. Now things I am going to turn off down on the status bar at the bottom of the screen are Polar, O-Track, Dynamic UCS. We only need Object Snaps and Dynamic Input switched on. But we need specific running Object Snaps switched on. So I right click over O-Snap, go to Settings and I'm going to do a Clear All first of all and then the Object Snaps I'm going to switch on are End Point, Center, Intersection and Extension. They will be the only Snaps that appear when I hover over objects on the screen. I'm going to click on OK now and those are the Snaps that I'm going to use. I'm going to zoom in on this area here like so and I'm purely going to use the Line Command and when I hover here now instead of putting in a coordinate I can left click on that end point snap. I can then drag my line to here at the next Object Snap which again is an end point and I left click, that line is now drawn. I can press Enter now, that finished the Line Command. If I press the Spacebar or Enter again that repeats the Line Command and I can now click on this Object Snap here and then this Object Snap here and again press Enter. So I'm drawing lines now without worrying about coordinate input. I'm now going to pan across slightly and look at the circles at the top of the object. I'm going to click on the Circle Command on the Draw Panel and use the Center Radius Option and I'm going to hover now over this circle here and as I hover over it you'll see the Center Snap appear, I can just touch on the edge of the circle or actually move into the center of the circle. If I left click now my new circle is utilizing the center of the existing circle and it's asking me for a radius. The radius is going to be 6 and then Enter. The smaller radius circle is now placed within the bigger circle. Now the benefit I have now is the Circle Command will remember the radius that I've just placed. So if I do a Circle on the opposite side now, so I press the Spacebar to repeat the Circle Command, hover over this circle over here on the right hand side now and get my Center Snap which is here, left click on the Center Snap, I don't even have to type in the radius. If I just press Enter it remembers the last radius drawn. So there's lots of little tools like that in AutoCAD that can make things that little bit quicker. Let's pan downwards now to the bottom of the object and what I want to do now is I want draw a line from the bottom quadrant of this circle and all the lines be Perpendicular to this line here. I don't have the quadrant snap or the Perpendicular snaps switched on. I can use override snaps. Now the quickest way to get to them is to use a keyboard shortcut. So I'm now going to click on the Line Command and come into the drawing area. If I now hold down the Shift Key on the keyboard and also press the Right Hand Mouse Button I get my Object Snap Override Shortcut Menu and I'm going to select Quadrant and now it will only select Quadrants, so I select the bottom quadrant of my circle there and I left click. There's my Object Snap, Quadrant and my line is snapped to that Quadrant Snap. So now I need a line that is Perpendicular to that vertical line. So I hold down the Shift Key again for the next point of the line and I right click, I then select the Perpendicular snap and as I hover over that line there's my Perpendicular snap, left click, Enter to finish the Line Command and there's my horizontal line going from the bottom quadrant of the circle Perpendicular to the vertical line next to it. Let's repeat that one more time, so it's Line Command, hold down the Shift Key and Right Click. I select Quadrant off the Override Snap Menu and I'm going to go for this Quadrant here on the opposing circle on the other side, there's my Quadrant Snap, I left click. My line now goes from that Quadrant so I Shift and right click again and select Perpendicular on the Override Menu and on this line here there's my Perpendicular Snap, left click, Enter to finish the Line Command, do a Zoom extents to have a look at your drawing and you'll see there now that you completed that exercise using some of the Object Snaps available to you in AutoCAD.
