In this video, we'll review the organizational structure of Rhino's pulldown menus at the top of the screen. This is actually a great place to find and learn new commands, but also understand their logical relationship to each other. I have this interesting thing that I call The Department Store Analogy. With this, we classify each of the Rhino three entities or categories is being located in departments. So, we have a department for curves, we have a department for surfaces and a solid department. Now this is further organized by levels.
So, at the top of any of these departments we have, create new ones, generate new geometry. At the lower levels, we have edit existing things that you already made earlier. So, all three of these menu sections are organized the exact same. We'll go ahead and do a few demos, just to further explain. We'll be making new geometry here of the three different types. For the curve, I'm going to select Rectangle. Now just a note: a curve is basically any type of line, whether it's straight or smooth.
So, I'm going to pick the Center to Corner. With a little bit of snapping, we have a brand-new square. Now let's make a brand-new surface. Surface menu. For the next two examples, we're going to extrude these shapes into a third dimension. Now these are something we'll cover in more detail in a later movie. So, I'm going to select these curves. So, there we have a new surface. Let's make a new solid. On the Solid menu, top floors, pretty much in the same general location as the prior one, Extrude Planar Curve > Straight.
I'm going to select the curve and then pick the end, and there we have a 3-dimensional solid from a curve. Those were all at the top section, since they were new. Now let's explore kind of editing existing geometry. For this example, I'm going to use Fillets on all three entities. This is another great example where a command can work on different types of geometry, whether it's a line, a surface or a solid. So, it's another way that you can extend your knowledge. First, let's Fillet, the square.
We'll choose the Curve, so here's the Fillet option, located on the lower level, radius of 3. I'm just going to verify that. You can change it by clicking at any of these options. Click the two sides, zoom in a bit, repeat, click the two sides, and there is a Filleted curve. We can do the same thing with the surface, lower-level, Fillet. Let's verify the radius is okay and just pick the two sides, Fillet at the Surface.
Last up will be the solid. It's the same command and the same general location, Fillet at the Edge. Just pick that top edge here, hit Enter. Now we've got a solid fillet. Many new Rhino users forget where a command is located. So, with this Department Store Analogy, you can easily find any command simply by asking, 'What are you making - a curve, a surface or a solid? And the next question, 'Is it new, or an edit to an existing one?' This system works really well, even when you can't remember the name of the command.
All you have to do is find the best department, the level, and take a look around, just like you're shopping.
