Ok Proctor, you got me curious. One appilcation for Region in 2D that I can see would be similar to converting something into simple block. If you draw a rectangle using the rectangle command, you can grab a corner and stretch it. But if you region that same rectangle, you can't stretch it anymore. It will only move if you grab a snap and drag it. Same with a circle. Try it. Draw a circle. Now click on it. You have snaps at the center and quadrants. If you grab one of those quadrant snaps you can change the size of the circle by dragging it. If you region that circle, then click on it, the only snap you get is the center. You can no longer stretch it, only move it. So in a sense you've converted that shape into a block without having to go through the steps of making a block. Now let's say you draw 2 concentric circles, then region both of them. You can move each one individually. But if you put up your Solids Editing tool bar and us the Subtract command to subract the inner circle from the outer circle, it still looks the same on the screen but the circles are now locked together, like a donut. If you click on it, both circles highlight and you get the same center grip but both circles will move together if you drag that grip and drag it.
Up until today I'd only ever used Region for 3D but now that I've thought about it, I can see a use in 2D: Giving a geometry set properties similar to a block without actually creating a block, and a block drawing file.
Thanks for sending me off on that little exploration. :-) |
