So, I have a Style setting, and this determines the orientation of the profile curves to the rail. Now we see the Sweep 1 Rail options and I see some settings that look similar to what we saw in the Loft command. Then when I've got the seam where I want it, I can either click Done or hit Enter on the keyboard. And this last one is already in the middle, so that's just fine. ![]() So, with my Midpoint object snap activated, I'll just go ahead and click to adjust those and snap them right to the midpoints of each of these profile curves. So for this one, I'd like the seam to run right along the top middle of all three of these profile curves. So, this means somewhere in that surface, there will be a seam where it wraps back onto itself and I can specify where that seam is, either using these command options here, so the Flip, Automatic, or Natural, or by manually clicking and dragging these points in the viewport. So now, I'm being prompted to adjust the seam point and since all three of these profile curves are closed, the swept surface will also be closed in one direction. And now, it's asking me to select the cross-section curves and here, I want to make sure that I do these in order, so I'll go one, two, three, and then when I'm done, I can either press Enter on the keyboard or just click Done. So I'll go ahead and click to select the rail. Now, Rhino's prompting me to select the rail. So let's just go ahead and do a simple Sweep 1 Rail on these curves, so I'll go to Surface, Sweep 1 Rail. ![]() We have one, two, three cross-section profiles and then our rail. I'll maximize my Perspective viewport by double-clicking and then just pan over a little bit and zoom in. So, right now, I'll just go ahead and toggle off the Visibility on the rest of these layers so we can see what's going on a little bit better. So let's start with these curves here and these are located in the Sweep1-A layer. So we can find these commands under the Surface menu or through the Surface icon or by typing into the command line. And Sweep 2 behaves almost exactly the same way, only it has two rail curves that define the surface edges. Sweep 1 makes a surface that passes through one or more profile curves and those act as cross-sections along with one rail curve that defines a surface edge. So we'll look at making surfaces with two similar Sweep commands: Sweep 1 Rail and Sweep 2 Rails. I've opened up surfaces-sweeps.3dm from the Example Files and here, we've got a few different sets of curves and surfaces and to work with. Chris concentrates on product design, but the lessons are just as valuable for those specializing in jewelry design, architecture, automotive design, or any other CAD-driven industry.- Let's talk about creating surfaces using the Sweep commands in Rhino 5 for Mac. This course assumes basic familiarity with working in Rhino, and builds off the core skills covered in Up and Running with Rhino for Mac. Plus, learn how to produce detailed drawings and layouts and prepare Rhino projects for digital fabrication. Chris Reilly covers basic interface navigation, 3D modeling, parametric modeling with Grasshopper, and rendering. Learn everything you need to know to get started designing with Rhino for Mac in this essential training course. Along with a few third-party plugins, Rhino's built-in features make tasks like 3D printing and laser cutting easy and intuitive. Its hybrid solid+surface modeling toolset is powerful yet flexible. ![]() Rhino for Mac offers a compelling 3D modeling experience for designers who prefer to work in the Mac environment.
