In this video, we'll get some extra introductory practice with our basic geometry of performing some basic transformations. Keep in mind this is just a brief demo, but we'll cover each of these transformation topics in much greater detail in upcoming sections. So, first up, I am going to grab this polyline and just move it with the drag by clicking, holding, and dragging. That's kind of a random movement, so I prefer nudging it with the arrow keys on the keyboard. We have four of the Cursor keys. Let's go ahead and check those settings and make sure the defaults have not been switched back.
So, I am going to click on the yellow gear to access Options. I am going to go to Rhino Options > Modeling Aids > Nudge, and make sure it says arrow keys or change it. Now when we revisit the geometry, we select it, and using the four arrow keys, it will move around a predictable amount each time in a predictable direction. Now let's visit the Rotate. We have an icon here on the main toolbar. We'll just to do a simple, two-dimensional rotation. I am going to select this surface here.
It asks for a Center of rotation so that could be anywhere inside or out. And then we start with a reference angle, which means you can click anywhere, and a second click after that is the differential rotation. So, I'd stop it rotating by clicking again. That's a simple rotation. Let's try Scale. I am going to use the Scale icon here for a three-dimensional Scale, which is the left-click button. I am going to select this box, and we can pick any origin to scale from.
It can be a point on it or off of it. Let's start outside, and again, we have a reference beginning, which is one point and then the second point. If you go farther away, it gets bigger. If you move in closer, it gets smaller. Let's do some copying and pasting to make additional copies. I'll start off with this hexagon here. We can make an additional copy by the Edit menu > Copy command. So, we've copied one to the Clipboard. We need to paste it to get it back into the scene.
So, now we should have two hexagons there and we do. So, let's move one of them away. We can do the nudge, to go to the side, but I am going to show you a new little trick. We are going to go nudge vertically so this will go perpendicular to the Z axis, and we use the keys Page Up or Page Down. So, I am just going to click it five times to get into five-unit separation. I am going to go ahead and repeat this a few more times, and we'll get a whole bunch of hexagons, Copy- Paste, Page Up five times: two, three, four, five, Copy- Paste, two, three, four, five.
If you do something you need to reverse, for example, you've moved this surface over aways. There is a simple undo with Ctrl+Z. So, creating objects goes hand-in-hand with the ability to transform them, whether it's moving, rotating, scaling, or just making lots of copies, you'll almost always spend far more time editing than you do creating.
