You can define up to three path curves. You can define open or closed path curves. When constructing swept features with more than one path curve, select the elements for the first path curve, then click the Accept button. Repeat this process for the second path curve. When constructing a swept feature using three paths, after you define the third path, the command automatically proceeds to the cross section step.
When using more than one path or cross section, each path curve must be a continuous set of tangent elements or edges. For example, if you define a path curve using a profile or sketch, the elements must be tangent at their connect points (A).
Note:
The path curve does not have to be tangent for a swept protrusion constructed with a single path and a single cross section.
When using more than one path curve, the order in which you select the path curves can affect the shape of the feature.
A swept feature is allowed to deviate from the first path curve you select. The swept feature typically will not deviate from subsequent path curves. Because of this, you can change the shape of a swept feature by changing the order that you select the path curves.
Path selection order can also determine whether the feature is constructed successfully, or fails to recompute properly.
In some cases, you also may want to consider constructing a loft or BlueSurf feature instead of a swept feature. For more information, see the Comparing Swept, Lofted, and BlueSurf Features section.
