Use the Sketch Path or Pick Path tool to draw the path for a sweep or swept blend
Use the sketching tools to create a path for the sweep or the swept blend.
The path can be a single closed path or a single open path. You cannot have multiple paths. The path can be a combination of straight lines and curves, and it need not be planar.
Use the Pick Path tool to indicate the path for a sweep or a swept blend.
To select edges of other solid geometry, such as extrusions or blends, click Pick 3D Edges on the ribbon. Or pick existing sketch lines, watching the status bar to know what you are picking. This method of picking automatically locks the sketch lines to the selected geometry and allows you to sketch the path in multiple work planes, hence allowing for a 3D path.
