Welcome to the Simply Rhino, Rhino for Mac Tutorial series. I’m Sean from Simply Rhino and in this tutorial I’ll be covering polyline, line segments, line and two freeform code commands, firstly control point curve and then interpret curve.
So let’s start by just looking at the line command. We can access the line command by placing my cursor over the polyline button here, holding down my cursor and sliding across here to line and release. Now in bold, it’s asking me here for the start of the line. My cursor has changed to a small pair of crosshairs which means that I can make a left click, or I can type in a coordinate or a distance in this line here. So I make a left click. Now I’m going to make another left click to define the end of the line. Now in order to repeat that command, I right click on the mouse and I slide along here to repeat line line and I make another left click. Now I’m just repeating this action to show you the both sides option. So I clicked on both sides there and you can see now that my line is being created, equidistant from the very first line that I chose. So by clicking on Ortho here, I am going to constrain my line to the horizontal and I make a left click. Now just drag a window across those and backspace to delete them.
Now, let’s have a look at polyline. Now if I click on this button here, polyline, start of polyline here in bold. So I make a series of left clicks. Now I’m constrained to 90 degree angles, so if I turn Ortho off I have now complete freedom. If I bring my cursor back to the very start of the line, I can find the very start by finding the objects that I can point. So that’s a polyline and if I select that, that will be selected as a single object because the point at which we have kinks, a kink is a sharp change in direction, the curves are joined.
Now let’s look at a line segment command. If I hold my cursor over polyline here, you’ll see that line segments is listed after polyline, so that means that I can make a right click in order to use the lines command, line segments. So I make a series of left clicks, very similar to the previous one. Again, we can close it with the left click. Now look, if I make a single left click on these objects, it’s going to identify them as single open curves. In order to flip between the two different states, I can select my polyline here and I can use my explode icon here to turn that into a series of segments, and just to do the same here, if I window select these objects here. Now I’m going to join them. So it’s as if this one now was drawn with a polyline and this one with line segments. We’ll see later how some commands require line segments, some require open curves. Now I’m just going to window space those, backspace and delete.
Now let’s have a look at some free form curves. We’ll be just having a look at two commands. If I make a left click over here, that’ll be a control point curve. You can see now over the top left hand corner, it’s looking for start of curve and there’s my crosshairs. Now if I make a series of left clicks on the construction plane, and you can see that the points that I pick don’t pass through them but it’s influenced by them. I press enter to close that.
Now let’s have a look at an interpret point curve. Now let’s find that on the list here. If I hold down my button I can come down to the third one and choose interpret points. I make a series of left clicks, now you can see how this differs. The curve that I’m creating is driven by the points that I pick, and of course we’ve got the undo here that’ll cycle us back through those points and to close that I just press enter on the keyboard.
Now let’s have a look at the control points of these two objects. Now I’m going to come across to here. Here’s my points on button and there’s my control points. So you can see now that I can window select some of these control points, and if I just drag them with the wheel of my mouse, we can see that that’s going to alter the shape of my curve and I’m just going to press escape twice to turn those control points off.
