48. Checking Your Skills • True_ False_ When creating a single rib or a web feature, you can only select a closed profile. • True_ False_ Both the Extrude and Revolve tool can use the minimum or maximum extrusion solutions. • True_ False_ You can only place embossed text on a planar face. • True_ False_ A sweep feature requires three unconsumed sketches. • True_ False_ You can create a 3D curve with a combination of both 2D and 3D curves. • Explain how to create a 3D path using geometry that intersects with a part. • True_ False_ The easiest way to create a helical feature is to create a 3D path and then sweep a profile along this path. • True_ False_ You can control the twisting of profiles in a loft by defining point sets. • Explain how to save both halves of a part after splitting it. • True_ False_ You can copy features between parts using the Copy Feature tool on the Part Features panel bar or toolbar. • Explain the difference between suppressing and deleting a feature. • True_ False_ After mirroring a feature, the mirrored feature is independent from the parent feature. If the parent feature changes, the mirrored feature will not reflect this change. • Explain why you would want to override a part’s mass and volume properties. • True_ False_ After changing a part’s physical material properties, the part’s color in the graphics window will change to match the material. • True_ False_ A derived part cannot be scaled.
