In this example, the path and the sketch are nearly identical to those used in Figure 3. Sweeps are powerful tools for modeling tubing, wiring, and other shapes that follow some sort of path.įor extra fun and excitement, the twist along path option can create a spiraled rotini noodle as shown in Figure 4. The profile must be a closed loop-or set of loops. The path can be made from a variety of lines, curves, and splines.
This example begins to reveal the distinctive advantages of sweeps. To create the elbow shown in Figure 3, I edited the path sketch by adding a second line and creating a fillet in the sketch. The sweep tool allows you to select which sketch to use as the profile (the circle) and which sketch to use as the path (the line). The final step was to launch the sweep tool. In this case, the path is just a straight line. Then a second, separate sketch for the path was made. This sketch is the profile-the cross section of the sweep. In this case, the sketch with the circle was completed first. It doesn't matter in which order the sketches were created. Figure 2 reveals the two sketches that were required. This example, however, was created as a sweep. The part in Figure 1 could have been modeled in any of several ways to achieve the same dimensional result.
Can you tell how it was modeled? Is it an extrude, a revolve, or a sweep? Without having access to the model, you really can't answer that question. Peek at a Pegįigure 1 shows a cylinder that has a 1-inch diameter and a 1-in. Second, we're going to cover only a little bit of what sweeps can do.
#SWEEP IN CHEETAH3D SOFTWARE#
First, if you're not using the same software as I am, some of the operational details and terminology may be a bit different. A sweep consists of three basic elements-a profile, a path, and a set of rules for "sweeping" the profile along the path.īefore getting too far into the details of sweeps, I am going to offer up a couple of disclaimers. Like an extrude or revolve, a sweep is a tool for modeling a 3-D shape.
