Performing Boolean operations on regions

“

In this video I'm going to discuss regions, and the Boolean operations you can use to manipulate them. Begin in a blank drawing, and draw a circle. The size doesn't matter. Draw a rectangle next to it. Draw an ellipse. And a polygon. I'll draw a pentagon over here. At this point, these objects are defined only along their perimeters. The interior of these bounded objects is mathematically undefined, if you will. What we're going to do is convert these objects into regions, and then they'll truly be two dimensional objects. Once that's done, we can then use Boolean commands to manipulate them. And that's where it really gets interesting. So let's go ahead and expand the draw slide out and click Region. Select all the objects you've drawn and press Enter. It says four regions created. You can only make a region out of something that has a closed boundary. We can't turn a line into a region because it doesn't contain an area. Now these objects are regions but they look the same. The…
