In Rhino 4.0 Essential Training, author Dave Schultze shows how the 3D NURBS-based modeling tools in Rhino 4.0 are used to engineer products from toy robots to full-sized aircraft. This course concentrates on using Rhino 4.0 for industrial design and rapid prototyping, with a review of common 3D terminology using specific examples. Along with a comprehensive exploration of the Rhino interface, the course includes an introduction to building 3D objects with Rhino's three primary entities: the curve, the surface, and the solid. Exercise files are included with the course.
In this video, we'll highlight the flexible nature of the Rhino interface. This flexibility means that you have the ability to run commands any of several different ways. So, this gives you considerable freedom, although it can sometimes add to your initial intimidation, or even confusion. So, at a bare minimum, you have four different ways to start any command and then two additional methods you can use to repeat those commands and really speed things up. So, for this example, we are going to use a circle each time. I am going to zoom in. And we are going to find it via the menu. It's under Circle.
And I am going to select the Center, Radius version, although you can see there is like six or seven other ways to start a circle. So, we click to these points that are already set up. I will just drag out any radius that looks good. So, that's the circle via the menu command. Now, you have probably seen all these little icons on the side of the interface and since the circle is the most common, it's in there also. So, I am going to start with a button click, Center, Radius. Third way is via Popup. Assuming your mouse as a center button or scroll wheel that can depress, you are going to click that now. And this is a fully customizable Popup menu of any command that you want.
Right now, it's got some of the defaults. So, I am going to drag the circle onto this little interface, put it over here. By holding down the Ctrl key, you can drag any icon that is visible anywhere in the Interface from its original position and make a copy. I am going to do it one more time, Ctrl+Drag. Now, we have two. The reason I did that is I want to show you how to remove a button if you have an extra or just want to rearrange these. You hold down the Shift, and that will move, and therefore delete, if you pull it outside. So, be careful that you don't use Shift to remove these interface buttons that really need to stay there.
I am going to close the Popup now for a second, just so I can bring it back up here, close to where I need it. There is the circle. Notice that the Popup, when it disappears that saves you a lot of screen space. And the final way you can do a circle is via the Command line. This is this text area at the top. I am going to type in the first letter of the command and notice we have a lot of matches, more than a full, screen full. So, you just type as many characters as it needs to zoom in and narrow down. There is the Circle command. You can just hit Enter. It will fill in the rest of the letters.
Notice the Command line gives you all the options too; we will get into those a little bit later. And I can draw a circle from the Command line - a little a bit old school, but it always works. Now let's get into Repeating Commands. As long as I am not in the middle of a command, I can right-click on the mouse, and that repeats the exact command that was previously done. There is our Circle. Now for jumping around and doing a circle, square and another shape and then back to circle, square, we have the option to go up to the Command line and click in a blank area, right-click, and that gives you the last 10 things you have done.
So, you can go back to 2, 3, 4 Commands, pick them and save yourself a lot of time. So, I'll just pick that Circle one last time. None of these four methods that can be used to start a command are inherently better than any of the others. So, as the course progresses, you'll see each of these entry methods used.
